Heritage Buildings – beauty or burden?!

Heritage Buildings - beauty or burden? 

       Castle Peep, Windsor – Internal Refurbishment within Conservation Area

There aren’t many people who don’t love the charm, character and history of our old buildings. But with their ownership comes responsibility and doing it wrong could be a criminal offence, which we’d like to help you avoid!


Preserving heritage buildings in England is a delicate balance of honouring the past whilst accommodating the needs of the present and future. England’s architectural heritage, symbolised by its Grade I and Grade II listed buildings and Conservation Areas, tells a story of historical, cultural, and artistic significance.


For owners of listed buildings, any changes—be it restoration, renovation, or adaptation—must adhere to stringent guidelines set out to protect their historical value. This is where Architects and Heritage Consultants can play a pivotal role.


We feel very lucky to be based in Windsor which is renowned for its rich heritage and architectural significance. We regularly work with historic buildings – Georgian townhouses, Tudor cottages, Victorian terraces and so on – against a background of planning and legislative constraints which rightly ensures they are protected.



Understanding the Listing System and Conservation Areas


The Planning (Listed Buildings and Conservation Areas) Act 1990 sets out the legal framework for the designation and protection of historic buildings. Listed buildings are graded as follows:


  • Grade I: Buildings of exceptional interest, constituting only 2.5% of listed properties.
  • Grade II*: Particularly important buildings of more than special interest.
  • Grade II: Buildings of special interest, warranting preservation.


Listing covers the entire building, including interiors and sometimes additional features like boundary walls or garden structures. Owners must obtain permission for any alterations that might affect the building's character or even it’s fabric; this might include putting pictures on the walls with nails!


Conservation areas exist to protect the special architectural and historic interest of a place rather than individual building. These are usually applied to an area that contains features that make it unique or distinctive. There are greater restrictions on work you can do within a Conservation Area without planning permission as councils look to preserve character and history.


It is also worth noting that the National Planning Policy Framework (NPPF) and/or Local Plans recognise non-designated heritage assets. These are buildings, monuments, sites or places that are considered important to a local area. Non-designated heritage assets are highlighted by local authorities or neighbourhood forums and are considered with greater rigor within the planning system.



The Architect’s Role in Heritage Preservation


So how can we help? Our role is to carefully balance the needs and desires of our clients against the limitations and requirements of heritage buildings. We hope to ensure that you gain all that you want for the project whilst protecting the history of the building.


1. Navigating the Planning Application Process:


When proposing alterations or repairs to a listed building, the first step is to submit a Listed Building Consent application. Artichoke can help you prepare the application by:


  • Developing Detailed Plans and Justifications: A successful application hinges on detailed documentation. Architects prepare scaled drawings, method statements, and written justifications demonstrating how the proposed works align with heritage preservation principles.
  • Producing a Heritage Impact Assessment (HIA): An HIA evaluates the potential impact of proposed works on the building’s significance. It considers historical, architectural, and cultural values, ensuring that alterations respect the building’s character and is justified.
  • Collaborating with Conservation Officers: Local authority conservation officers oversee listed buildings in their jurisdictions. If possible, we will engage with these officers early in the process to discuss plans, gather feedback, and incorporate their recommendations. Depending on the project, this might extend to liaison with Historic England – a public body and a statutory consultee in the planning system.
  • Understanding Local Conservation Area Appraisals: These documents outline the key characteristics and priorities for each conservation area. We will always ensure that the proposed works align with these guidelines.


2. Building Regulations Compliance:


Heritage buildings are exempt from modern standards, such as insulation requirements, though compliance with building regulations is still necessary. Architects play a crucial role in:


  • Balancing Conservation and Compliance: Retrofitting a heritage building for modern use can be challenging, especially when introducing fire safety systems, insulation or accessibility features. We enjoy this creative process and look to provide solutions which meet building regulations without compromising historical integrity.
  • Working with Specialists: we will liaise with several external consultants to ensure the project is successful. Key consultants are:


Structural Engineers (SE) – in all instances, we will seek advice from an SE to determine how best to support the building.


Planning Consultant – if a project is complex then we may seek detailed advice from a planning consultant to ensure that a project is fully compliant in advance of a planning application.


Heritage Consultant – as above, if a project is complex then we may seek detailed advice from a heritage consultant to ensure that the building(s) is preserved in a way that ensures its longevity.


Sustainability Consultants – in many instances, we will seek advice and assessment from a Sustainability Consultant. Each project is unique and so we need to understand which materials are best placed to enhance building performance without compromising the structure.


3. Advising on Appropriate Interventions:


Retrofitting heritage buildings is a critical strategy for achieving the Labour government’s carbon reduction goals. These goals aim to create a net-zero carbon economy by 2050, with the built environment playing a significant role due to its substantial contribution to national emissions – approximately 40% of the UK’s carbon emissions.


Retrofitting involves upgrading existing buildings to improve their energy efficiency and reduce carbon emissions. For heritage buildings, this process is more challenging due to unique construction methods. At Artichoke, we understand these challenges and can advise our clients on appropriate methods for integrating energy-efficient measures such as renewable energy sources. We can also help develop strategies to upgrade building performance without impacting the buildings heritage or longevity such as internal insulation systems that maintain the building’s natural breathability.


Case Studies: See some of the successful heritage projects below which have delighted our clients and have been incredibly rewarding to be a part of:

Church Farm, Surrey – Contemporary Residential Extension to Grade II Listed Building

A 17th century house which was originally part of Lord Lucan’s estate. It has a modern kitchen, dining and family space with a perfect balance of harmony and contrast providing a beautiful bright space to the delight of our clients. 

The Weir Cottage, Maidenhead – Refurbishment and Extension within Conservation Area

An old coach house, originally around 1/3rd of the size of what it was when we were involved. Unfortunately, it had previously been extended without much thought, so Artichoke had to be very creative to produce the bright open spaces the client needed whilst respecting the character and fabric of the house. Again, delighted clients and wonderful outcome. 

Castle Peep, Windsor – Internal Refurbishment within Conservation Area

Very much like Weir Cottage, but in this case, there were no extensions and all the magic happened within the existing house. Even so, a truly dramatic and incredible transformation! 

Manor Farm, Laleham – Refurbishment of Grade II Listed Buildings within Conservation Area

A charming heritage farmstead in the works. Artichoke is proposing the restoration of the house and barns, sensitively designed modern additions and a set of commercial units that blend into the context to ensure the longevity of the site.


Preserving England’s heritage buildings while adapting them for a sustainable future is a challenge that requires vision, expertise, and collaboration. Artichoke is equipped to guide clients through this process by ensuring compliance whilst achieving great design and functionality.


By embracing innovative solutions, Artichoke can help clients transform heritage buildings into energy-efficient spaces, demonstrating that conservation and sustainability are not mutually exclusive. For any heritage building owner, engaging a skilled architect is an essential step toward achieving these objectives.

If you’ve ever tried to extend your kitchen in Windsor and been met with more red tape than a royal ribbon-cutting, you’ll know this area isn’t exactly straightforward when it comes to building projects. Listed buildings, conservation areas, green belt, flood plains—and now, just to keep us all on our toes— biodiversity net gain . Yes, that’s right. The butterflies are now part of the planning process. And we’re absolutely here for it. We’re a small, design-obsessed architectural practice in Windsor, and we love a challenge. If your project comes with layers of complexity, maybe a 300-year-old wall or a site that’s prone to the odd flood, then you’re speaking our language. We’ve spent years navigating the quirks of this patch of Berkshire, and we know how to make the tricky stuff feel like the exciting stuff. So if you’re thinking of building, extending or reimagining your home (or even your business), let’s talk about why now is actually a brilliant time to get going—and how the new planning rules might just be the thing that pushes your project from good to gorgeous. What on earth is Biodiversity Net Gain? Let’s start with the buzzword: Biodiversity Net Gain , or BNG to those in the know. As of 2024, new developments in England (yes, even the small ones!) have to leave the natural environment in a better state than it was before. In simple terms, if you knock down a shed and build a garden office, you might also need to give something back to nature—think wildflower beds, hedgehog highways, green roofs, bird boxes, ponds… that kind of thing. And the aim is not just to replace what was lost, but to increase biodiversity by at least 10%. The government has officially asked us all to get a little greener—and in a town as leafy and heritage-laden as Windsor, that’s actually a lovely thing. What does that mean for your dream extension? Well, don’t panic. You’re not going to have to turn your back garden into a nature reserve. But it does mean the design process now includes a bit more imagination and a lot more collaboration with nature. For us, it’s like being handed a new palette of materials—only this time the materials are living, breathing, and occasionally fluttering. We might be talking about: Planting native species in your landscaping (the kind the bees actually like) Installing green roofs that soak up rain and look brilliant from above Creating little corridors for wildlife to move through (so the hedgehogs can get to their Friday night pub, presumably) Using permeable surfaces to reduce flood risk while still looking sharp It’s a challenge, yes. But it’s also an opportunity to make every project that bit more thoughtful—and beautiful. Why this is actually good news for Windsor Let’s be honest—this area is full of hoops to jump through when it comes to planning. But BNG actually fits in quite nicely with the way we already work. Here’s why: We already love working with heritage – Listed buildings don’t scare us. We know how to celebrate old features while sneaking in modern comforts and wow-factor spaces. We’ve got the green stuff down – With years of experience building in the green belt and flood-prone zones, we’re no strangers to weaving nature into the design. We believe in better – Whether it’s your forever home or your first leap onto the property ladder, we think good design should improve everything it touches: the lives inside the building, the neighbourhood it sits in, and now—the environment too. And let’s not forget—Windsor is special. We’ve got a town full of character, history, and people who genuinely care about where they live. So making things just a little bit wilder, greener, and more alive? It feels like exactly the right direction. But isn’t this going to make things harder? Well… maybe a little. You will need to work with someone who understands the new rules and can guide you through them without the process feeling like an uphill battle with a clipboard-wielding bureaucrat. But here’s the thing—we’re already doing this. We’re already weaving these ideas into our designs, already chatting to ecologists and planners, already sketching up ways to turn “requirements” into design features you’ll actually love. Think: a living wall on your new garden room, or a hidden bin store that doubles as a bug hotel. (Yes, that’s a thing. And yes, it can look great.) So… what kind of projects are we excited about? If you’ve got a listed cottage in a conservation area that needs a contemporary extension—let’s talk. If you’ve got a patch of green belt and a wild dream of a modern eco home—call us. If you’re a local business owner looking to build something bold but sensitive to its surroundings—we’re in. And if you’re just not sure where to begin, but you know you want a team who cares about getting it right—not just for the planners, but for the people and the planet—we’d love to help. Final thoughts (and an open invitation) Building in Windsor isn’t always straightforward, but that’s what makes it brilliant. There’s a richness to the fabric here—a layered history, a complex geography, a deep connection to landscape and place. And now, there’s a renewed call to design in harmony with the natural world. If that sounds like your cup of tea (preferably sipped in a light-filled extension overlooking a wildflower garden), then let’s chat. We’re here to help you navigate the quirks, embrace the challenges, and create something truly special. And who knows? You might even make a hedgehog happy in the process. Get in touch  We're a friendly bunch, and we’d love to hear what you’re planning. Whether it’s a single-storey extension, a new home, or something totally unexpected—we’re all ears. And sketchbooks. And strong tea.

People are often quite surprised at the time it takes (and no amount of forewarning prepares them for dealing with local authorities)! Embarking on an architectural project is an exciting yet daunting prospect and understandably, one of the most frequent questions we get when speaking with new or potential clients is “how long will the whole process take?!”. As every project is unique, so is the timeline. Projects vary in scale, brief, budget and location and timelines will be adjusted to suit this. Following our recent post about planning fees and timescales https://www.artichoke-design.co.uk/planning-fees-to-increase , this post walks you through our typical phases of a residential architectural project, provides timescales for each phase and hopefully encourages you to jump into your project with confidence (leaving yourself plenty of time)! Phase 0 – Initial Consultation (1-2 weeks) The journey begins with your initial vision for the project – this might be high-level or detailed (or you may have no idea how to get to what you want) – and your engagement with an Architect and/or other professionals. At Artichoke, we will arrange an initial visit to discuss the project and will hopefully come armed with a good understanding of the site (based upon a preliminary desktop review) to answer any burning questions you may have. During this phase, there are several key steps involved: • Project Brief Creation: We will work with you to define the goals and scope of the project. This involves discussing your vision, budget and expected timeline so that we can advise accordingly. • Initial Design Discussions: Early design ideas are often explored from the offset. As Architects, we are excited by design, and we will likely use this initial site visit to give our first thoughts about what might be achieved and the routes forward. • Fee Proposal: Considering our discussions, Artichoke will then produce a detailed fee proposal setting out our services, which are tailored to your needs. Phase 0 – Kickstarter Package / Feasibility (+4-6 weeks) • Feasibility: Depending on the complexity of the project, we may propose that we conduct a feasibility study to determine whether your vision is likely to be viable within the constraints of the site and budget. We have setup our ‘Kickstarter Package’ https://www.artichoke-design.co.uk/kickstarter , for a fixed fee for those clients who might benefit from a high-level initial assessment. Phase 1 - Survey and Design Sketches (+4-12 weeks) The pre-construction phase is typically the longest and most involved part of the design process as you navigate through the design and statutory approvals. We have broken this down into Phases 1-3 with Phase 1 being the first step forward: • Measured Survey: we will need measurements and critical information about the site to produce a set of existing drawings (floor plans, elevations and sections). Depending on the scale and complexity of the project, we may carry out the survey ourselves or outsource TO a surveyor to do this on our behalf. • Design Sketches: this is where the fun begins! We find that the best and quickest way to consider your design options is to produce a series of hand sketches. This is where we can provide our clients with ideas that may push the limits of their imagination. We welcome an open dialogue to ensure that our clients can voice their opinions (good and bad!) so that the final product is exactly as they desired. The first set of designs will be presented to you in person so that we can take on board all feedback and alter the drawings for your final sign off.

It’s likely that many architects and planning agents will be overwhelmed with people trying to get in early to avoid the increase in fees. Anyone with a project in mind should consider the time needed even to get the point at which a planning application can be submitted. Typical timeframes: 6-18 weeks + 1-4 Weeks – Find & appoint an architect + 1-2 Weeks – Measure property & prepare existing drawings + 2-8 Weeks – Prepare & develop design options with client meetings + 2-4 Weeks – Prepare planning information and submit application The Government released draft legislation on January 14th, to propose an increase in planning fees. In many cases this will rise by 100% or more. Although one exception sees an increase of 583% – albeit for major developments. This goes against the previous rise under the last Government where planning fees increases were to be pegged to the rate of inflation or a maximum of 10%. The biggest impact will be felt for changes of use with prior approval under Class MA, Class Q etc., and householder applications. The issue is that planning fees are not ring-fenced for the planning department – therefore these fees could go almost anywhere! Maybe even to purchase more government folders at £600 each! The planning departments need an increase in funds, but this legislation does not guarantee they will receive any of the increases. The Government estimates that the shortfall in overall funding for local planning authorities is estimated to be £362 million. Despite this, there is zero guarantee that this will not still exist in 2026 or it may even increase! The prices rises of of 100% or more, come after planning fees rises in December 2023 of 35% for major and 25% for all other applications. It is advisable to ensure that applications and fees are submitted before 1st April 2025 to avoid these fees. Applicants are reminded that the ‘free go’ on planning fees was removed in December 2023. Householder Applications Where permitted development is not possible under Part 1 of the GPDO, then a householder planning application is required. These fees are increasing for the enlargement, improvement or other alteration of a dwelling house. Increase the fee for applications for the enlargement, improvement or other alteration of a single-dwelling house from £258 to £528 – an increase of 105% • Increase the fee for applications for the enlargement, improvement or other alteration of two or more dwelling houses from £509 to £1,043 – an increase of 105% • The fee of £258 for householder developments related to small-scale operations within the curtilage of a dwelling house is not changing – this would be for items such as garages, outbuildings, porches, gates, fences and walls It is always advisable to see if you can just go ahead under permitted development. Contact Planning Geek if you need guidance on this. Click here to contact us. Prior Approvals Most changes of use under Part 3 of the GPDO will require a prior approval application. • The flat fee for prior approval applications that don’t involve building operations is increasing from £120 to £240 – an increase of 100% (was £96 before December 2023) • The flat fee for prior approval applications that involve building operations is increasing from £258 to £516 – an increase of 100% (was £206 before December 2023) • The fee for prior approvals relating to the change of use of Class E uses to residential (under Class MA of the GDPO) is increased from £125 per dwelling house to £250 per dwelling house – an increase of 100% (was £100 before December 2023) The fees for prior approvals related to the construction of new dwelling houses are not changing under Part 20 – these remain at £418 per dwelling. Section 73 Applications If you wish to alter a previous planning decision to perhaps remove a condition or alter the drawings etc., you would use a Section 73 application. These fees are altering from a previous flat fee of £293. These applications are now to be divided into three options depending upon the original application. To alter a householder application you may opt to wait until after 1st April, as this reduces by 70%, but for a major development this increases by w whopping 583% • £86 for householder applications – a decrease of 70% • £586 for non-major development – an increase of 100% • £2,000 for major development – an increase of 583%!! Discharge of Conditions The fee for an application for approval of details reserved by condition is increasing from: • £43 to £86 for householders – an increase of 100% • £145 to £298 for any other development – an increase of 106% Fee for submission of a Biodiversity Gain Plan is increasing from £145 to £298 which is an increase of 106% In Conclusion The last government increased planning fees by either 25% or 35% – at the time, householders and business were told that planning fees would increase each year by the rate of inflation or a maximum of 10%. Today, Matthew Pennycook the Minister of state for Housing and Planning at the Ministry of Housing, Communities and Local Government has decided to ignore that legislation. These fees will now increase by inflation or 10% from 1st April 2026 and beyond. That is unless the government decides to increase them again. These increases in planning fees will impact SME developers who will need to budget for the increase in fees as part of the conversion costs. The government is pushing forward with plans to allow local authorities to vary or set their own fees. This is likely to be limited to a percentage of the new fees announced today. All other planning fees remain unchanged until April 2026 – for now! The Planning Portal site is yet to announce their fees for processing your card payments to local authorities from 1st April 2025. Since early 2022 this fee has risen from £28 to £70 today – a 150% increase in under three years. 1st April 2022 – £32 including VAT (a 14% increase) 2nd May 2023 – £64 Including VAT (a 100% increase) 2nd April 2024 – £70 including VAT (a 9% increase) Note - Planning Portal is a private company owned by TerraQuest Solutions Limited. The site was privatised in 2015. Get in touch If you have a project in mind, please do give us a call or email and we’ll be delighted to discuss it with you.

Designing your dream home is one of the most exciting journeys you’ll ever embark on. But let’s face it—turning ideas into reality can feel overwhelming. How will the materials you love look together? Will the rooflines and proportions match your vision? That’s where 3D modelling and AI steps in to transform your design experience. Although relatively new, this game-changing technology lets you see your home take shape in stunning detail before construction even begins. From the overall form to the finest exterior details, 3D modelling brings your ideas to life in a way that 2D plans simply can’t match. Visualizing Form and Massing One of the biggest challenges in residential design is understanding how a building’s form will look and feel in the real world. With 3D modelling and AI, you can explore every angle of your home’s design. See how rooflines interact, how the building’s massing complements its surroundings, and how different elements—like porches, balconies, or overhangs—enhance the overall look. This level of visualization empowers you to tweak and refine your design until it feels just right. Want a more striking silhouette? Or perhaps something that blends seamlessly into the landscape? With 3D modelling and AI, it’s easy to test ideas and find the perfect balance between bold and harmonious. Exploring Materials and Finishes Materials are the soul of any home’s exterior, and choosing the right combination can make all the difference. With 3D modelling and AI, you’re no longer limited to imagination or tiny swatches. You can see how natural stone looks next to wood siding, how a slate roof pairs with steel accents, or how bold colours interact with neutral tones. Better yet, 3D modelling and AI provides realistic lighting effects, showing how your materials will look at different times of the day. Will the sunlight bring out the warmth of your timber cladding? Does the texture of your chosen brick create the depth you want? These are the details that bring a home’s exterior to life, and 3D modelling and AI ensures you get them right. Smoothing the Planning Process Let’s talk about planning approvals—often one of the trickiest parts of building a home. 3D modelling can simplify this process by providing highly detailed visuals that planners and local authorities love. A clear, realistic depiction of your design in its actual context helps address common concerns about scale, proportion, and how the home fits into its surroundings. Plus, it helps the planners and your neighbours to truly understand what you are proposing and by offering a comprehensive view of the project, you reduce misunderstandings and demonstrate your commitment to quality and cohesion, which can speed up approvals and minimize delays. Why Settle for Guesswork? Why rely on guesswork or even thinking what it might look like when you can know exactly how your home will look, feel, and fit into its environment? 3D modelling takes some of the uncertainty out of the design process, empowering you to make confident decisions about form, materials, and style. It’s not just about creating a home—it’s about creating your home, with every detail just the way you want it. Ready to turn your dream into reality? With 3D modelling, the journey to your perfect home starts now. If you have a project that you are considering, please do get in touch, we’d love to hear more about it and discuss how we might be able to help.

We’ve had a truly exciting end to 2024. After a couple of years where global and national situations have meant a lot of people have had no choice but to tighten their purse strings, confidence has grown and we’ve seen a real increase in the number of people contacting and working with us. In an effort to try and stimulate enquiries and to forge relationships with other consultants (and following the success of Windsor Designs Live 1 & 2!) we organised and held a larger scale event, Thames Valley Build & Design Live 2024. The focus of this event was orientated towards larger scale projects and across a broader geographical area. Again, it was a great success and we’ll be discussing details of future events in 2025 with our partners. Historically we’ve almost exclusively worked on residential projects, both extension and new houses. In recent years we’ve had more opportunity to work with commercial clients on their projects; these include residential developers, hospitality, schools, farms and healthcare. The sector in which we’ve experienced the most significant increase from our typical work is schools’ projects and are now delighted to be working with 3 amazing institutions on projects varying from staff accommodation to the development of a rowing site for the staff & team to train at. • Ludgrove School • Green Room School • The Windsor Boys School (Boat Club)
