He studied architecture at the University of Sheffield, Oxford Brookes University and the University of Westminster. His postgraduate work was awarded an RIBA Award, which lead on to featuring in Wallpaper Magazine’s Graduate Directory identifying the next generation of designers, and an interview with the Financial Times.
A core passion is designing bespoke stone furniture that exists at the confluence of art, sculpture and product design. Through Joseph’s role as Creative Lead of the studio Etraterra his work focuses on the shaping of rare and lesser known stones into singular pieces that hold a bodily coherence.
Will’s approach to architecture is underpinned by a strong interest in vernacular architecture and climate responsive design born out of academia at the University of Sheffield and London Metropolitan University, where his research explored Sri Lankan architecture and urban redevelopment in Mumbai’s historic Mill lands.
