Purpose-built foundations for garden rooms & annexes.
Garden rooms and annexes are our most-requested application. The building location will be surveyed and, in most cases, installed and load tested inside a single day, giving your builder a level, dry, ready-to-go platform with no waste, no concrete and no waiting.
Where we deliver for this sector
We regularly install ground screw foundations for home offices, garden gyms, annexes and studios and cabins.
- Home offices: Level, insulated-ready bases for timber frame studios.
- Garden gyms: High point loads handled by engineered pile schedule.
- Annexes: Habitable outbuildings with Building Control sign-off.
- Studios and cabins: Timber and steel bases across all garden types.
Challenges we solve
- Narrow side access and gated back gardens
- Existing lawns, patios and planting to protect
- Sloping ground that concrete cannot easily follow
- Short build windows where concrete curing kills the programme
