Architecture & Interiors

Our core business is the delivery of excellent architecture and interiors: buildings, internal spaces and places that contribute to their context, communicate thoroughness and quality in their organisation and construction, and perform for their occupiers. We treat interiors as an intrinsic part of the design process and ensure that interior specialists from our firm are involved throughout the development of a project. The practice provides a full range of professional project services under the RIBA Plan of Work and we are known to our clients for our responsive and pro-active approach, and our ability to adapt to an evolving brief.

Adaptive Re-Use

The practice has a wide range of experience in the renovation, conservation and adaptive re-use of heritage building assets, having helped clients bring new life to a variety of structures from early Georgian townhouses to early 20th century office buildings. Working closely with specialists, we strive to find simple, creative solutions to problems such as how to introduce efficient services, how to provide occupier flexibility and how to facilitate expansion in floor area while enhancing features of special interest within the original building.


GarnettArchitecture is experienced in office design and fit-out, helping clients create dynamic workspaces to enhance team working, improve communication and provide flexibility to adapt to change. Our workplace consulting team has in-depth knowledge of how good office design and fit-out can substantially improve business performance, enhance clients’ branding and help retain and attract key people. Typical services include site selection and space planning, client brief analysis and leadership of the design process through to completion.


GarnettArchitecture creates elegant contemporary homes ranging from multi-million pound city developments to stunning individual houses that stylishly fulfill our clients’ requirements.

Each project is approached as a unique piece of design blending together traditional materials and state-of-the-art technologies to create comfortable, stylish and contemporary homes.
