Ground Screws for Garden Rooms | Garden Room Foundations

Why We Focus on Garden Rooms

The UK's Fastest-Growing Outdoor Build — Done Right

Garden rooms are being built at record pace across the South East. And the one thing every garden room needs — before a single wall panel goes up — is a solid, level, accurate foundation.

We specialise in that foundation. Not as an afterthought, but as the entire focus of what we do. We understand garden room builds, the tolerances they require and the impact a poorly installed foundation has on the finished structure.

Ground screws are, in our experience, the best foundation solution for garden rooms. They're faster than concrete, less disruptive, more precise and easier to work with for both homeowners and installers.

The Right Foundation for the Job

Why Ground Screws Work So Well for Garden Rooms

Traditional concrete footings are over-engineered for most garden room projects and create unnecessary disruption. Ground screws are a better fit in almost every way.

Ready to Build the Same Day

No waiting for concrete to cure. Ground screws are installed in hours and your garden room build can start immediately — keeping projects on schedule.

No Garden Disruption

Ground screws go in without excavation. There's no turf to lift, no spoil to remove and no heavy machinery churning up the garden. Your customers will appreciate it.

Level & Square Every Time

We install to exact levels. For garden rooms this matters — a millimetre out at the foundation becomes a visible problem at the roof. We get it right at the start.

Suitable for All Typical Ground Conditions

Our screws perform reliably across clay, loam and sandy soils — the ground conditions most commonly found in South East England gardens. We carry four lengths to match whatever your site needs.

Right-Sized for Garden Rooms

Garden rooms don't need the deep foundation of a commercial building. For most, our 1.25m screw provides the right load-bearing capacity. Where conditions or structures call for it, we carry 1m, 1.5m and 2m lengths too.

Suitable for All Garden Room Types

Whether it's a home office, studio, gym, playroom or garden bar — our foundation system works for any garden room design or manufacturer's system.
