Orangery roof framework

The guys are pushing ahead building the roof framework, the blockwork piers can be finished at a later stage. An orangery seems like a simple structure, but there is a surprising amount of work involved. Although we have used a steel portal frame, we have still used glulam beams to form the main structural opening for the lantern roof.

The positions of the roof joist are planned in advance using our CAD system, this means the spacings will suit the desired lighting layout. The flat roof area needs to be laid to slight falls, to direct the rainwater towards the outlets.
