Details & Spec

Our Log Cabin & Shed is a premium quality garden building and offers a light and airy contemporary space in which to work, rest or play. This popular building makes the ideal-sized garden studio or office.

This superb quality log cabin is manufactured from heavy-duty 45mm timber and is double-glazed as standard. With insulation to the roof & floor, the building is temperature controlled all year round. All our garden cabins are manufactured from high-quality, Northern European Spruce, slow grown in managed forests, making them very eco-friendly & importantly, built to last a lifetime.

The tongue and groove wall boards fasten together, and sturdy roof joists support a tongue and groove ceiling creating the building shell. Timber doors and windows slot into place and an EPDM rubber roof is installed with aluminium roof trim. The floor is made of 21mm tongue and groove timber but can be upgraded to easy-clean laminate or vinyl flooring.
