Building Retrofit

Retrofitting involves modifying existing buildings for the purpose of improving energy efficiency, decreasing energy demand, & additional reinforcement – therefore resulting in a more sustainable structure. We take great pride in the effective solutions our engineers devise, and the great value this provides to our clients. We also take time to ensure we conduct thorough research into the existing structures to understand past, present and future concerns that have arisen. Our portfolio includes projects such as, 9 Millbank, The Kodak Building, Riverbank Plaza, The Stables Market – Camden, and URW HQ; which further evidence our expertise in this specialism.
