Working Group Design is a small, busy architectural practice based in central London.

Founded by Ben Pentreath in 2004, the office specialises in traditional architectural design and planning.

We have a particular interest in large-scale residential housing projects and have worked on major sites owned by The Duchy of Cornwall, English Partnerships, and BP. In addition we design a small number of substantial private houses.

The practice is interested in demonstrating that modern, sustainable design can be seamlessly incorporated within traditional architecture. In 2007 our site at Upton was awarded the BRE’s highly valued ‘Best Ecohomes’ award.

We are committed to providing an excellent service and to designing buildings that are long-lasting, beautiful, and robust.
