Garage Conversions in Egham.
Converting a garage in Egham raises one question that does not arise in most of Surrey, and it is worth addressing before anything else. Parts of Egham, Englefield Green and the land running down towards the Thames sit within the flood plain, and a garage is frequently the lowest floor level on the plot. It was built that way deliberately: a garage is not habitable space, so a slab that sits low and falls towards the door is entirely sensible.

Specialist focus in Egham.
Turning that space into a habitable room changes what the floor has to do. The level has to come up to meet the house, the construction has to account for the property's flood position, and the materials used at low level should be chosen with that in mind. None of this makes a conversion in Egham a bad idea — it remains the least disruptive way of gaining a real room — but it does mean the floor deserves more thought here than it does elsewhere, and we would rather raise it at the first visit than after the work has started.
As a premium design-and-build company we take on a limited number of projects at a time, so that every one gets the attention it deserves. If you are planning work on your Egham home, we would love to hear about it.

What we deliver in Egham.
- 01
Floor Level & Build-Up
The garage slab typically sits below the house floor and falls towards the door. We build the floor up to run flush with the rest of the ground floor, incorporating insulation and a damp-proof membrane within that build-up rather than treating the level change as a finishing detail.
- 02
Flood Position & Materials
Where a property sits in a flood risk area, the sensible approach is to specify the lower part of the construction accordingly and to keep electrical outlets and vulnerable services above the likely level. We check the property's flood position as part of the first visit so the design accounts for it from the outset.
- 03
Insulation & Damp-Proofing
Garage walls are not built to habitable standards, and a low, riverside floor makes the damp-proofing more important rather than less. We insulate and damp-proof the full envelope so the finished room stays warm and dry through the winter.
- 04
Frontage & Building Control
We infill the old opening and match the brickwork and detailing to the existing elevation, and every stage is inspected and signed off by building control. Runnymede Borough Council is dealt with on your behalf, including any application required.
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.

“Very helpful, proactive and competitive design/build quote. The initial video consultation was very useful, and Conor was very proactive in following up on my questions. The detailed cost breakdown was very helpful in understanding where I could perhaps reduce costs. If you are looking for a design and build company to discuss your project, I have no hesitation in recommending Conor and the Grand Innovations team.”
