Renovating a house is an opportunity to transform the way you live. Whether it’s to improve functionality, modernise outdated interiors, or restore original features, house renovation projects can breathe new life into a property. In a city like London, where space is at a premium and building stock is varied, careful planning and experienced guidance are essential. At Armstrong Simmonds Architects, we deliver thoughtful, high-quality house renovations tailored to every client and home.
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.
We are a RIBA Chartered architect studio based in Battersea, with over 15 years of experience in residential architecture across London. From period townhouses to post-war homes, our work spans a wide range of styles, scales, and constraints. What sets us apart is our integrated approach – combining architectural vision, technical precision, and an understanding of how our clients live today.
Choosing our team means working with professionals who understand local planning policy, building regulations, and the design opportunities each property holds. We don’t apply a one-size-fits-all template. Instead, we listen carefully to your needs and design spaces that are functional, elegant, and enduring.
Whether it’s a full interior reconfiguration or a complete house refurbishment, we manage the process from the initial concept to completion, incorporating Architectural Planning services and liaising with local authorities when required.
The cost of house renovation in London varies depending on the property size, complexity of works, specification, and location. However, based on recent projects, a full house renovation typically starts from £1,500 per square metre, with high-end schemes exceeding £2,500 per square metre.
Factors affecting renovation costs include:
At Armstrong Simmonds Architects, we provide detailed guidance on budget expectations early in the design phase and help you balance ambition with practicality.
Every renovation begins with a clear understanding of your goals. Our process ensures every detail is thoughtfully considered and aligned with your vision.
