Matter Architecture is a new practice, but with a great breadth of experience. The buildings and places we design are uplifting, responsive to their context and enduring for people to use and enjoy for the long term.

Matter is an RIBA Chartered Practice formed in 2016 by Roland Karthaus (formerly principal of Karthaus Design) and Jonathan McDowell (partner McDowell+Benedetti 1996-2016).

We are currently working on a wide range of projects across all building types and scales, for public, private and trustees clients. These include community and education projects, housing, commercial, infrastructure and bridges, public realm, urban design and masterplans.

We avoid narrowly specialising so that our mix of work makes for a rich and creative environment in which every project is unique and benefits from a breadth of knowledge and research.
