It basically started out as a place of storage but progressed to something far more than a basic shed. To see what can be acheived when you push the boat out. Plus it was built single handed by myself during summer 2021.
Its built from wood with a log lap exterior and breather membrane with 50mm insulation between the outer and inner walls to stop condensation and draughts. Its fitted with light and sockets. If a small heater was fitted you could possibly camp in it as its draught free and fully insulated. The roof was stretched out to use 1.5mm rubber with some artificial grass on top. Some left over triple wall roofing sheets were incorporated into the roof as a skylight.
There was no design, i just looked at shed ideas and came up with my own.
