Greenwich Rear Extension & Kitchen
Case Study · Greenwich, London

Greenwich Rear Extension & Kitchen

The Challenge

Opening the rear of a 1930s semi into one room meant removing a load-bearing wall between the existing kitchen and the new extension, on a site where a narrow side passage was the only route for materials in and spoil out. The new ground-floor shower room also had to be formed within the existing rear lobby, well away from the original layout's plumbing.

Our Solution

The structural opening was formed with a steel beam cased into a shallow flush bulkhead that follows the line of the removed wall, keeping the ceiling clean and the sightline from kitchen to garden completely open. Deliveries were sequenced in small daily loads through the side passage to keep the neighbouring boundary clear, and services for the new shower room were routed within the extension's floor build-up so no boxing-in was needed in the finished rooms.

The attention to detail and absolute financial transparency provided by Grand Innovations completely redefined our expectations of what a home renovation could be. High standard of work, the extension is beautiful and has added so much value onto our home. Really appreciated the weekly billing, rather than a big amount upfront.
