Construction
The walls are built from 12mm tongue and groove boards on a 28mm x 28mm frame, planed to a smooth finish. Delivered in interchangeable modular panels, using more overall timber than a standard summerhouse, it goes together more easily and results in a stronger structure. The floor is a solid tongue and groove floor, promoting airflow underneath and helping prevent damp and rot.
Treatment & Guarantee
The timber is pressure treated and FSC certified, sourced from sustainably managed forests, and backed by Forest’s 25 year anti-rot guarantee. This means the wood never needs re-treating against rot, saving you time and the cost of annual preservative. The building is supplied unpainted, so you can finish it in whichever colour suits your garden.
Doors & Windows / Security
Access is via double doors fitted with a secure locking system and high quality fittings. The doors and 5 large windows are glazed with 4mm toughened safety glass, which is far tougher than standard glass and safer for a busy family garden.
Assembly Information
This summerhouse is delivered flat packed with all fixings and clear instructions, via Forest’s White Glove Delivery Service, which brings it straight into your garden with the packaging removed. The modular panel design makes assembly more straightforward than a traditional summerhouse.
