Assent Surrey was appointed to carry out building control on this project in Cadogan Gate, Knightsbridge. The Project constructed to an exact specification both to the structural and interior finishes. Due to the existing footprint size, a fire engineering approach was required to achieve the required level of habitual space and to increase the floor areas as a development. A combined method of a full sprinkler system with an aspirating smoke detector system incorporating a smoke venting control was used. This projects shows without question that fire engineering solutions can work alongside with the properties of the highest interior specification.
