Our Process

Embracing unusual and challenging briefs, we produce work across a broad spectrum of disciplines and range of scales for private residential, commercial and local authority clients. The diversity of our projects creates productive juxtapositions in processes, problems and materials. As a practice we are particularly interested in the potential for architecture to communicate identity and intelligently resolve briefs whatever the context through an understanding and synthesis of cultural references, social context and technical feasibility.



Investigation, experiment and discovery takes place both within the practice and through our engagement with academic institutions. Most recently we have been working with the London School of Architecture to address concerns around Health and Wellbeing. We have also run architectural studios at the Architectural Association, Royal College of Art and UAL.



The team responded to the brief with an energetic, imaginative and well planned installation which successfully articulated the qualities of our Sto Acoustic materials range.
