Case Study

11 Westminster Road

11 Westminster Road

A new extension to the rear of a property. Initially we were contracted do design the structural steels required for the opening between the new extension and existing house structure, and to support the opening for the new bi-folding doors. While on site the contractor discovered that the existing property had been constructed upon a raft foundation due to historic landfill use of the site, in addition to being congested with a number of publicly owned services. We produced a design for a raft foundation slab to support the new extension that also needed to navigate around the services. Throughout the project we worked closely with the client, contractor and building inspector to ensure compliance with regulations while minimising project disruption.
