We are renovating our house bit by bit. Our present back porch is only 4 feet by 4 feet (External) with rotten wooden window frames, single brick built on top of a concrete path with no foundations as far as we know. I have battened the internal walls covered with aquapanel and tlled. This has been satisfactory.
The roof is plywood and felted. It mainly houses the tumble dryer (not much room for anything else!) which is vented to outside. What I propose is something similar but 8 foot X 4 foot external dimensions; still single brick dwarf walls as double would take up too much space; 2 feet of concrete foundations. concrete floor. the 8 ft X 4 ft is just under the 3 sq meters for exemption from planning.
Battened and aquapanel and tilled dwarf walls as now . Plastic windows and door on one 8 foot side. Plastic window frames and plastic panels on other long wall. End wall to be one or two plastic windows. If the double glazers fit corner posts at each corner I would like to know if just the double glazed and door sections would support a wooden roof frame made out of 4" x 2" with such timber forming a wall plate all round and spars at 16" centres. Flat roof to be a sheet of 8 ftx 4 ft ply ( say 1 inch thickness) with wooden facia on three sides and tarred felt roof. This would give us access to the bathroom window above. I know I will have to ask my PVC installer but apart from them and the felter I will be doing the rest myself so I would just like to know whether this is feasible.
If the PVC double glazing is not designed to carry much load then an alternative method would be to put 50mm x 50mm galvanised steel square tube fabricated with plates at top and bottom at each corner tight up to the brickwork,to take the weight of the roof taking into account snow loading. These could be erected with the roof frame on top ready for the PVC to measure up before manufacture.
Thanks
