We are an RIBA Chartered Practice based in Bethnal Green, London. Matter Architecture was formed in 2016 by Roland Karthaus (formerly principal Karthaus Design) and Jonathan McDowell (formerly partner McDowell+Benedetti). Matter is committed to creating places and buildings that improve people’s lives through the energetic pursuit of excellent design. The practice combines the great breadth of experience of its directors and staff: across varied sectors and scales of architecture; and across numerous roles in design, research and education.
