Arran joined JMP in 2007 and was promoted to Associate in 2009.

His experience spans many scales and typologies. Across his projects, the experience of the end user, sustainable design and attention to detail remain his key concerns. He is currently leading the Olympic Energy Centres project, which will provide energy to the London 2012 Olympics site and surrounding communities. The project required significant pre-application consultations with 45 stakeholders, the Olympic Delivery Authority and the Planning Decisions Team.

He directs JMP's work on Sunderland Justice Centre, a highly complex building housing 20 Crown, Criminal and Civil courts on a prominent site within the city. The project is envisaged to form the key component of the city centre regeneration. Also under Arran's lead is a major mixed-use project in Istanbul, comprising two towers with high-end residential and retail elements.
