Ground screws for garden rooms, studios and garden offices, supplied across the UK or installed by our team. The layout is planned around the floor, frame and ground.
Many garden rooms use timber or steel floors that can sit on individual support points. That makes ground screws a practical alternative to a full concrete base on many sites.
The screw positions still need to match the actual garden room. Beam spans, wall lines, door openings and heavier items inside the room can all change where support is needed.
The footprint is useful, but the support grid has to follow the actual structure.
Timber, steel and modular garden rooms can need different screw positions and fixings.
Longer spans or heavier areas can need extra support points.
Ground levels, what is under the surface and machinery access affect the installation.
The screws need the right heads, brackets or beams to connect to the floor or frame above.
Supply-only can suit experienced installers and repeat garden-room builders with their own installation process. Orders should include the right screw sizes and fixings for the garden room.
Ground screw supplyForti Nova can set out and install the ground screw foundation, then leave it ready for the garden room frame or floor.
Installation process
If you also need a light gauge steel frame, Forti Nova can plan the ground screw positions to match it. That avoids designing the frame and foundation separately and finding out later that the support points do not line up.
Combined foundation-and-frame pricing can be discussed for suitable projects.
Discuss foundation + frameProjects where discrete supports work structurally and reduced excavation, garden disruption or concrete curing are useful.
Projects where a continuous base, slab strategy, ground condition or design requirement makes concrete the more appropriate route.

Straight answers on screw quantity, size, cost, when you can start building and how ground screws compare with concrete.
Yes. Ground screws work well for many garden rooms because they can mean less digging and there is no wait for concrete to cure. The right layout still depends on the garden room, the ground and site access.
There is no reliable screws-per-square-metre rule. The number depends on the floor and frame layout, the spans between supports, any heavy point loads, the size of the garden room and the ground.
Understand load and layoutGround screw size depends on the weight of the garden room, the ground, how the frame fixes to the screws and how deep the screws need to go. The room dimensions alone are not enough.
See the size and depth guideCost depends on how many screws are needed, their size, site access, location, ground conditions, any support beams or brackets and whether you want supply only or installation too. Compare the full foundation cost rather than one screw price.
See the cost guideThey can be where reduced excavation, restricted access or avoiding a concrete curing period are priorities. Concrete can still be appropriate for some sites and floor strategies, so the foundation should be chosen around the actual garden room and site.
Compare with concreteThe ground screw foundation itself does not need a concrete curing period. Once the installed foundation has been checked and accepted for the project, the frame or floor stage can normally proceed.
