Structural engineering comes in all shapes and sizes, and Simpson TWS was pleased to support CanaCabins on a particularly challenging small-scale project in south London.
The client’s vision was to create a sunken indoor golf range, a design requirement driven by planning constraints. However, the site presented a significant technical challenge, being located within an area densely populated with protected trees, placing strict limitations on excavation methods, foundation depth, and load distribution.
Working closely with the project team, Simpson TWS developed a solution that balanced structural performance, environmental sensitivity, and planning compliance. The chosen approach utilised a waterproofed raft slab, installed over a substantial layer of heavy-duty protection, and supported on screw piles. This solution minimised ground disturbance while providing a stable and durable foundation system suitable for the constrained site conditions.
The foundation design supports a bespoke timber structure, carefully detailed and attractively finished, demonstrating how considered engineering can enable high-quality architectural outcomes—even in technically demanding environments.
This project highlights Simpson TWS’s ability to apply innovative structural engineering solutions to unconventional developments, ensuring that planning, environmental, and technical challenges are resolved without compromising design intent. We are proud to have contributed to a successful outcome for CanaCabins and to yet another example of how thoughtful engineering can unlock complex sites.
