A family run practice serving London and the South East

Our two co-directors, Graham Stevensen and Matthew Stevensen, have been working on projects together for over 15 years, ranging from small domestic projects to multi-million pound projects.  They have coordinated design teams  appointed by renowned institutions such as Guy’s and St.Thomas’ NHS Trust and University College London.  They are both involved on every single project, bringing together their different skills to create balanced, thoroughly considered designs.

Graham Stevensen is the Principal Architect with over 30 years experience in practice.  He is well versed in multi-disciplinary roles, and performs the role of Lead Consultant and Contract Administrator on our larger size projects.  He has a particular interest in conservation and historical architecture, having worked on numerous Listed Buildings and buildings of architectural significance.  He is also the Quinquennial Inspection Architect for numerous churches within the Diocese of Southwark.  He has a wealth of experience within the healthcare and education sectors, and is currently on the Board of Governors for King’s Oak Primary School in New Malden.

Matthew Stevensen is a building designer with over 15 years experience in practice with Graham.  He is primarily responsible for coordinating the designs and developing the virtual models.  He uses state-of-the-art design tools including Vectorworks (for 2D drawing), Archicad (for 3D construction drawings and Building Information Modelling), Sketchup and various performance modelling packages.  Over the past few years he has developed a strong skillset in sustainable building techniques (such as PassivHaus design) and renewable technologies.  He is also an aspiring self-builder and has a predominant role in ensuring that our designs are cost efficient.
