Living roof construction.
Living roofs are self evidently a good idea. We will have a nice lawn for sitting on in the evening sun, rather than an expanse of tiles. It will reduce the amount of water that runs off the roof, keep the building cool in summer and reduce the heat that would bounce back from a hard surface into the warming sky.
The roof is constructed from I-beams and waterproofed with two layers of roofing felt. To create the living roof we will adda butyl pond liner, drainage layer, soil and finally turf.
The course will cover all stages, from design to construction and finally to reclining in the evening sun with a large G&T.
Adding the topsoil has to happen before the straw bale walls can be rendered.

Work will begin on the weekend of 28th & 29th April and continue on the weekend of 5th & 6th May 2007
As well as the activities listed on the homepage we will also be building the 'bottom edge' of the roof. This prevents the soil falling off the roof and acts as a drain for rain water. It will be made from wire mesh and filled with pebbles.
