New-build homes • extensions • interiors • basements

New Build House Architects
Our studio is dedicated exclusively to contemporary residential architecture and interiors. We are committed to designing and delivering distinct and beautiful bespoke homes within London and across the UK.

Every project is unique; tailored to each clients’ lifestyle, aspirations and specific location. We always approach the design as a collaboration between the designer and the client, arriving at a unique and bespoke solution that is both beautiful and atmospheric, whilst also being functional and practical.

Residential Extension Architects
Oliver Leech Architects is dedicated exclusively to contemporary residential architecture and interiors. We have a proven track record of creating beautiful award-winning extensions in London and across the UK.

We have experience designing extensions to a wide variety of existing homes from Victorian houses to listed buildings, working within relevant planning constraints to maximise the potential of the site.

Every project is unique; tailored to each clients’ lifestyle, aspirations and specific location. We always approach the design as a collaboration between the designer and the client, arriving at a unique and bespoke solution that is both beautiful and atmospheric, whilst also being functional and practical. As architects, we are trained designers and problem solvers. We will ensure that every element of the house and extension has been thoughtfully designed and co-ordinated to maximise the success of the project.

We offer a holistic approach and consider the extension within the context of its setting, creating a coherent relationship between inside and outside and designing a vision for the external spaces to create a consistent language for the project.

Interiors
Our studio is dedicated exclusively to contemporary residential architecture and interiors. We have a proven track record of creating beautiful award-winning homes in London and across the UK.

The most successful projects are those where the architectural and interior design are developed together for a shared language and holistic vision for the spaces. Deciding upon the look and feel of each room is often a personal journey for the client, influenced by their travels, hobbies, artwork or furniture. Therefore we always approach the design as a collaboration between the designer and the client, arriving at a unique and bespoke solution that is both beautiful and atmospheric, whilst also being functional and practical. Surface finishes, lighting, door handles and bathroom fittings are all selected with specific intent to create a beautiful experience that enriches everyday life.
