We design and deliver residential, commercial, industrial, sport, leisure and education projects.

Forty8 Design has significant experience in the design and delivery of architectural projects across a variety of sectors, both large and small. We welcome partnerships with fellow consultants, and can also undertake those projects which require our own expertise with the backing & resource of a larger practice.​ Throughout our first business year we have worked with domestic clients on private house extensions, social housing providers with national coverage, media facilities for Higher Education, Feasibility studies for Sport & leisure facilities and Industrial storage units. Our approach is always to treat every project with the same care and attention to detail. Client satisfaction is the ultimate goal.
