Concrete & Steel Foundations


You do not need to provide a concrete base for our garden offices.

To save you the expense and inconvenience, we use specially designed, concrete pile foundations combined with heavy duty galvanised steel legs and plates. The steel legs can be adjusted which means we can install our garden offices onto either flat or slightly uneven surfaces.

Your garden office will be raised off the ground to allow a vented space underneath. This ensures that the structure will not be affected by rising damp.

Thermowood Timber Cladding


Each garden office is externally clad in Thermowood heat treated tongue and grove timber. Thermowood`s heat treatment produces a consistent brown tone for a beautiful appearance with outstanding durability, stability and insulation characteristics.
