The main material for the shed is Reglit glazing which was destined for a skip. Reglit is a U- channel in section. 5' lengths are used for the walls and 8' for the roof. The shed includes automated opening vents to create cross ventilation and prevent overheating.
There is also a solar powered irrigation system. Rainwater is collected from the roof and pumped internally by the power of the sun.
Ok, its probably more greenhouse than shed!!
The shed has no foundations as such. 6 paving slabs (1 in each corner and 1halfway down the long sides)were positioned perfectly level on a sand/cement mortar. Timber bearers than span between these.
