🐭 “Won’t a raised base create a nesting spot for rodents?”
It’s a great question — and one we get asked a lot.
The reality is rodents aren’t attracted to Ground Screw Bases themselves. They simply look for sheltered spaces, and this can happen under any garden building — including those on concrete slabs, where the timber bearers usually sit just 2–4 inches above the surface, creating a small dark gap.
With a Gorilla Base, the situation is very different. Our structural timbers are typically 150 mm deep, and because the frame sits on ground screws, there is usually 175–250 mm of open clearance underneath. This creates a large, bright, well-ventilated space — not a tight enclosed void — making it far less appealing for nesting.
Even more importantly, lifting the building off the ground allows airflow to circulate underneath, preventing damp, rot, and premature timber failure. This is why buildings installed on raised bases often last significantly longer than those sitting directly on concrete.
As with any outdoor structure, rodents are best prevented by simple good practice: keeping the area tidy, avoiding stored food sources, and maintaining the surroundings — not by the type of base itself.
✅ Better airflow
✅ Longer building lifespan
✅ No damp trapped under your shed
That’s the real difference a raised foundation makes.
