    At Armstrong Simmonds Architects, we help you protect the past while creating something ready for the future.

    Listed Building Architects in London

    Looking for Experienced Architects in London?

    Aside from providing you with a beautiful design, your architect needs to navigate complex
    planning and building laws that regulate the construction industry. Therefore, appointing a
    practice with the right amount of experience is the key to a smooth project delivery. Although
    not essential, appointing a RIBA chartered practice is also an important factor to consider.
    Being RIBA Chartered means that the practice must adhere to a code of conduct of
    professionalism and ethics which ensure quality control within the Architectural industry. The
    experience of the practice within London is another important factor to consider, particularly,
    as each borough has different modes of operation which can influence the design process.

    Whilst the National Planning Policy Framework (NPPF) provides the backbone for planning
    policy, each individual borough will have its own set of policy and guidance. A particular
    challenge within the borough of London is the planning process for basement design. For
    such a complex undertaking, stringent planning requirements must be met in the form of
    traffic reports, geology surveys and more. Another challenge is the added complexity of
    working with historic buildings. If your building is within a conservation area, a designated
    building of interest, or a listed building, any work to that building or surrounding area will be
    subject to strict requirements that are typically more rigorous than standard planning
    requirements. London Architects and designers must ensure their clients are advised
    appropriately on the process and that suitable consultants are appointed to conduct the
    necessary work.

      Unlock the Potential of Your Listed Building in London

      Listed buildings are protected for a reason – they hold architectural, historical, or cultural significance. But that doesn’t mean they can’t evolve. With the right approach, you can restore, adapt, and even extend a listed property without compromising its character.

      Our architect studio has expertise in thoughtful renovation and sensitive adaptation. Whether you’re restoring listed buildings to their original beauty, or making subtle updates for modern living, we balance creativity with compliance.

      Why Choose Our Services for Your Listed Building

      Renovating a listed building is never a one-size-fits-all project. It demands a deep understanding of heritage constraints, planning regulations, and construction techniques that respect the original fabric of the property. That’s where we come in.

      Our Design Process for Working with A Listed Building

      Working with a listed building calls for precision, patience, and expert coordination. Here’s how we guide you through the process, step by step:

      Icon
      Initial Survey & Consultation

      Our typical survey process involves taking detailed measurements of the property which we use to develop design options. When carrying out the initial survey and briefing, we may also highlight the need to involve other specialists during the concept design process. This may be relevant for structural understanding or other matters related to the heritage asset.

      Icon
      Planning & Design Strategy

      We develop tailored proposals that respect the building’s heritage while meeting your brief.

      Icon
      Coordination with Specialists

      We work closely with listed building specialists, surveyors, and engineers who understand the complexity of heritage work. This creates the foundation for a smooth project from day one.

      Icon
      Project Oversight

      From sourcing appropriate builders for listed assets to managing project timelines and budgets, we aim to communicate effectively with each party throughout the process – so your project moves forward with minimal stress.

      Our Flat Conversion Process

      We follow a clear, step-by-step process to ensure every flat conversion is thoughtfully designed:

      1

      Concept

      Briefing & Survey
      Armstrong Simmonds Architects will work with you to develop a concept design, sketching layout options to explore the potential of the property. We will also carry out a full measured survey of the property and its surroundings, allowing us to produce an accurate set of drawings.
      2

      Planning

      Application & Scheme Design
      Following on from the briefing we will prepare a set of scale drawings reflecting the range of ideas discussed. We will prepare and submit the planning application, liaising with the council as needed throughout the process. Our extensive experience will help facilitate a smooth planning process.
      3

      Visualisation

      3D Modelling Services
      To help you visualise the space in three dimensions we can produce internal and / or external views of your project. This can also be a useful tool to demonstrate the merits of the scheme to planners.
      4

      Technical

      Building Control and Detailing
      We will produce detailed technical drawings including drainage and electrical layouts, consulting with you to ensure the design meets your needs. We will then submit to building control and manage the approval process. As part of our architectural services during this process we can assist you in appointing other consultants, for example the structural engineer or party wall surveyor.
      5

      Specification

      Interior Architecture and Schedules
      We offer interior architecture and design for a high spec finish. We can produce further detailed information integrating specialist glazing components, floor finishes, joinery and bespoke staircase design as required.

      We provide Interior design architecture services ourselves or through collaboration with other London based Interior Designers, who may also be appointed by the client.
      We are happy to specify FF&E (furniture, fittings and equipment) for the project, providing a complete “one-stop” shop for your development.

      Tendering

      Prices and Builders
      We will help you make an informed choice on an appropriate contractor. We maintain a selective tender list of contractors especially in the local London area, who we have experience working with on site. We will prepare tender documentation and appraise their quotes.

      We are glad we found Armstrong Simmonds Architects to help us on our first project. We had bought a run-down terraced house near Clapham Common with the goal of extending and refurbing to increase value. John initially impressed us by first listening carefully to what we wanted to do, then showing us creative ways to achieve the results and finish we were looking for.

      Safe to say we certainly have managed that and both John and Alan have been instrumental in doing so. The guidance and consideration at every step have exceeded our expectations and Alan’s attention to detail during the build has been critical for the high standards we have set for this project.

      They have provided us with a service which reflects every stage of the design and build. Starting with the initial drawings, schedule of works, tendering and interior design. We also employed ASA for Contract Administration to be the key middle-man between us and the builder, which they were happy to help.

      We are now underway with our second project with ASA and they have been able to deliver the final drawings for planning within a fairly tight time frame, without hindering on quality. I know the whole team worked hard to help bring our vision to life and it’s been brilliant working with them over the last 18 months. They have shown a great ability to solve any issues that arose quickly and are able to communicate effectively with different contractors at all levels. I have no doubt the next redevelopment project will go well.

      We chose Alan and John for our extensive project and incredibly pleased with that choice and the result. We have a Victorian terraced house and wanted to do a classic loft conversion and ground floor extension. The Armstrong Simmonds team provided a vision which achieved our goals, but with a design we could have never have thought of ourselves which we love. We used them from start to finish and are incredibly glad we did. Alan supported us through the tender and renovation processes, and we are incredibly pleased with the end-product and the quality of work of builder Cezar of Vecchini. We would highly recommend Armstrong Simmonds for their vision, design thoughtfulness and exceptional assistance through the project. Thanks team!

      We worked with Alan and the team from Armstrong Simmonds for 3 years from start to finish to achieve the full renovation of a London townhouse. It was a challenging brief given the nature of the property but collectively what has been achieved is an outstanding end result. Alan and John thoughtfully incorporated our vision with the realities of converting an old Victorian house and the scrupulous attention to detail, symmetry and balance achieved in the design were instrumental in us choosing Armstrong Simmonds in the first place.

      In addition Alan supported us through the tender and during the renovation working with our excellent builder Cezar of Vecchini to deliver the brief. I would highly recommend if you are looking for a team to turning your vision to the end product with a very high attention to detail while still being good humoured and a generally great guy to work with. Thanks again team. Dom and Kamilla

      John and his team have been brilliant to work with for our full house renovation and extension in SW London. Our house is quite unique and that combined with it being in a conservation area we knew it wouldn’t be a straight forward planning process – but Armstrong Simmonds did a fantastic job and helped us navigate us through every step. We couldn’t be happier with the detailed design and outcome.

      FAQ

      What permissions do I need to renovate a listed building?

      When renovating a listed building, listed building consent is often required. There will also be occasions where planning permission and listed building consent are required. We handle this process for you, navigating your selected proposals through the relevant planning, conservation and building regulation requirements.

      Can I make modern updates to a listed building?

      Yes - but carefully. While original features must be preserved, smart and sensitive design allows for modern living upgrades.

      Do I need special permission to renovate a listed building in London?

      Yes. Any alterations, renovations, or extensions to a listed building require Listed Building Consent in addition to standard planning permissions. At Armstrong Simmonds Architects, we guide you through this process, preparing the necessary applications and ensuring your project complies with heritage regulations while achieving your design goals.

      What are the different grades of listed buildings (Grade I, II*, II)?*

      Listed buildings in the UK are classified into three grades. Grade I buildings are of exceptional interest, Grade II* are particularly important buildings of more than special interest, and Grade II are of special interest. The level of protection and scrutiny increases with each grade.

      What types of works require Listed Building Consent?

      Listed Building Consent is required for any works that affect the character or historic significance of the property. This can include extensions, alterations, and sometimes even minor changes to materials or details. We advise on this early and manage the application process where required.
