Eton Wick Hall Conversion
The Challenge
Inserting an entire new floor into a double-height vaulted hall meant carrying significant new loads through a building never designed for them, while keeping the original envelope and roofline completely untouched.
Our Solution
A structural steel frame was threaded through the hall and taken down to new pad foundations cut into the existing slab, with an engineered timber floor zone spanning between the steels — so the new storey lives entirely within the original walls.

“Grand Innovations Surrey were exceptional from start to finish. We had full ground-floor remodel and a rear extension built, and the communication throughout was brilliant. Conor and the team kept us updated every week and made the whole process feel organised and stress-free. The workmanship is excellent, the finish is beautiful, and the attention to detail really shows. We'd happily use them again and recommend them to anyone planning an extension.”
