Luxury Architect for Home Extensions
Christopher David Design is a luxury architecture and interior design studio specialising in house extensions in Surrey, London and throughout the South East.
As a specialist studio of residential architects for house extensions, we deeply understand the exciting potential of an extension to create a home that is truly ideal. Whether it’s space for a growing family, a thriving working life, generous entertaining – or indeed all of those – engaging an architect for a home extension makes it possible to live an ideal life in an ideal area.
At Christopher David Design, our studio’s signature, in-depth interview process allows us to thoroughly explore each client’s needs, preferences and lifestyle, expertly establishing a personalised vision for their home. By applying thoughtful planning practices and meticulous design expertise, we expand upon what a client already loves about their home, and bring to life a space that allows for uncommonly abundant living.
The wealth of expertise and experience across architecture, interior design, landscape design and project management makes the Surrey-based team at Christopher David Design a house extension company with a completely comprehensive approach. By listening intuitively to our clients to fully understand their lifestyle, we can deliver thoughtful, innovative design solutions. We aim to exceed expectations with results that allow clients to savour the greatest potential of their home.
Bespoke Luxury House Extensions in Surrey & Beyond
When clients engage Christopher David Design as their architect for a home extension, the experience is custom-tailored and scrupulously managed from concept to completed building. From beautiful hand renderings and drawings that generate inspiration and capture the imagination, to detailed architectural plans that describe how dreams will become reality, we help clients see and realise the potential in their homes.
When approaching a house extension project, we thoughtfully consider each client’s needs, tastes and desires in harmony with the existing building, character and context of their home. It is our conviction that a thoughtfully designed home can make all the difference in being able to live a truly full and satisfying life. So we listen carefully to truly understand how the client wants to live in their home, whether that’s expanded space for entertaining and family life, a peaceful oasis for rest, stylishly functional areas for hobbies and work – or indeed, all of those.

Every opportunity is taken to rethink and improve the space. In the transformation, we find ways to create subtle but striking “moments” in the design to support a rich living experience. Choosing a considered palette of materials, colours and finishes means a cohesive, harmonious feeling in the extended space. Using the right blend of depth, texture and aesthetics achieves a balanced and beautiful relationship between old and new. By maximising the building’s best features alongside improvements and additions, we create a luxurious, livable result with character and presence.
We leverage our wide and trusted network of connections with talented contractors, consultants and artisan trades so the inclusion of all the varied elements of the finished design is smooth and seamless. On behalf of our clients we deftly navigate everything from local planning permissions and council restrictions to on-site administration, technical considerations and structural requirements – so the process is as satisfying as the result.

An Inspired Creative Process
The homes we create are not only aesthetically beautiful, but also feel luxuriously comfortable and welcoming to live in. Each environment perfectly caters to the client’s vision and aspirations.
Our clients are expertly guided through the process of making decisions at the optimum point for their individual timeline, so that the design journey feels smooth and enjoyable, and the results are impeccable
Intuitive Vision
Naturally, our process begins by exploring a client’s preferences and practical needs, inspirations and aspirations – how they live, and how they want to feel in their home. What home means to each client is highly personal; lifestyle is a form of individual, creative expression. The deep level of understanding we aim for in these first conversations helps intuitively establish a creative vision – which will carry the project through from initial ideas and concept sketches, to design and planning, to implementation and completion.
Handcrafted Concepts
Whilst we fully embrace the potential of technology to enhance the design process, we believe that the architecture of a home is first and foremost an art form. We always begin designing with traditional visualisation – first sketching concepts by hand, in keeping with the tactile, artistic origins of our craft.
We share these bespoke concept sketches and initial layouts with clients from their earliest stages, establishing a strong foundation of rapport from the very beginning. We continue to collaborate as the design develops, deepening trust and understanding over time.
Cohesive Curation
We take great care and pride in our craft, from the first line drawn, to the final, finishing touches – offering our clients a full range of architectural services from design and planning to interiors and landscape design.
Along the way, we collaborate with a trusted network of artisans, tradespeople and craftspeople to deliver a richly layered, harmonious home. We’ve built an abundant network of relationships with contractors, consultants and collaborators from innovative lighting designers to artisan cabinet makers – allowing for the creation of a home that’s cohesive and beautiful in every detail.
Turnkey Results
We believe in being hands-on through all stages of the process from concept to completion, until a client is settled and comfortable in their new home – and even beyond. We liaise directly with builders, trades and other consultants, expecting the unexpected and ensuring that the creative vision is interpreted as intended. Our meticulous, experienced, expert project management means that clients truly enjoy the design journey, with exceptional results.
