Epsom Garage Conversion

The Challenge

Integrating the existing, lower-level garage slab with the main house floor level while ensuring maximum ceiling height for the new living space.

Our Solution

We engineered a stepped foundation and structural raised floor that perfectly matched the home's interior levels, creating an invisible, flush threshold between the original and new spaces.

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.
