creativemass is a design-led boutique architecture and design practice, based in Battersea, London, founded by Claire McDonald and Graham Massey. With a uniquely creative approach that embraces a client’s brief we create simple, beautiful, delightful, elegant places in which to live and work.

Our projects range from new and refurbishment projects in Kensington, Chelsea, Belgravia, South West London and the Home Counties, to a recent commission for a mountain cabin retreat in the Swiss Alps.

We understand the challenges of balancing family life with the demands of a busy work life, and we work closely with our clients to create bespoke spaces and solutions designed carefully for them and how they live.

Having collectively designed many award-winning buildings over the last 20 years, we know how to make spaces that are uplifting, practical and special, and with a timeless elegance.

We are passionate about design, and our attention to detail and hands-on approach from both Directors when overseeing projects, ensures that our clients benefit from a  fully comprehensive service tailored to each client and each project requirements.

Our website has some images of a few selected projects to give you a feel for our passion and our approach but we would prefer for you to contacts us to see a more comprehensive portfolio of projects, or to arrange to meet us and talk about your individual projects ambitions…


Having met in 1994, during the early days of their respective architectural careers in London, Graham and Claire embarked on diverse paths in the profession, gaining extensive knowledge and experience in a range of architectural fields.

Since joining in partnership in early 2011, they have together created projects which have earned them a reputation as outstanding architects with a unique attention to detail whilst bringing a personal touch to make each project special, tailored to the client’s desires.

Our team has always been, and will continue to be, small, hand-picked and close-knit, well versed in the creativemass approach to feasibility, design, construction and management of residential and commercial projects. Our shared ambition is to realise our clients’ complex design briefs on time and on budget.
