Concrete slab

Concrete Slab to be in accordance with Local Building Control guidelines, typically minimum 150mm reinforced concrete slab.

Screw piles

Screwpiles are a less intrusive way of supporting your Garden Studio compared to concrete slab. They are positioned at maximum of 1.2m centres to match the Timber Splines in the Sip floor. Screw piles enable a level base to be positioned on sloping ground without the need for expensive excavations.
