How to Build a Glasshouse - Basic Structure

Floor of the glasshouse is reinforced concrete approximately 75mm (3in) thick with the footings strengthened to about 200mm (5in) thick around the edges. Using scrap timber, make the formwork to receive the concrete, nail temporary lengths of timber across the formwork with holes accurately positioned to take holding-down bolts. It is easier to position bolts before commencing concreting than trying to accurately place them after pouring.

Concrete is four parts metal, two parts sand, one part cement, reinforced with welded reinforcing mesh or with 6mm or 8mm steel rods laid to form a 300m mesh. Leave floor approximately seven days to set. Plan shows a solid concrete floor over complete area; as an alternative a 200mm wide x 200mm deep (9in x 9in) strip footing can be poured under plates with the main glasshouse area covered with a layer of gravel or ashes.
