Located in our Brighton Design Studio, our small team of experienced professionals are adept at identifying the needs and aspirations of our clients, and we bring our skills in design and space planning, thorough documentation, technical knowledge and efficient project coordination together to deliver creative and practical design solutions.

Our ongoing experience working with our property developer clients means that we can assist our clients in exploring a number of options for the development of their site and help to identify the right product to optimise its yield.

In addition our local knowledge and understanding of planning and building controls enables us to navigate the often challenging approvals processes.
