Mark Patten

Technical & Design Manager

Mark qualified as a Civil Engineer in 1991 and worked on site in the industry for 10 years involved with piling, mass earthworks, retaining structures, sewage and water treatment works, roads, bridges, rail and Underground projects. During this period he went from engineering control to senior site management. This took him into general construction where he developed building experience culminating in complex hospital and school developments. Mark’s interest in detail/co-ordination/technical problem-solving led him into design management running tender and pre-construction schemes through to active sites for large design and build contractors. The Wine Society project was his introduction to renewable building materials and he subsequently joined Ian at Lime Technology to assist product development and accreditation. Mark now leads the design team.
