It is a room -- in the garden. It has lighting, power, wi-fi, stereo system, a bed, a reclining chair, double glazing, insulation. It rotates to offer different aspects of the garden and is sheltered from the afternoon sun.
My father's cousin was a priest in Scotland and had a garden room in which we used to dine when we visited in the summer and it inspired me to have my own. I won a competition about 15 years ago where the prize was £2,000 and I vowed when I retired that I would spend that money on woodworking machines. I bought a sliding table saw, a band saw, a morticing machine (I love making joints) and have since added sanders, router, nail gun, biscuit joiner etc. I found a heap of roof timbers about to be burned on a bonfire, so I retrieved and de-nailed them. I also found 4 window frames on said bonfire and set about designing a garden room. I always draw up my creations first - I find many construction problems by doing so.It is 8 feet square but without the 2 front corners, as if an octagon. The whole sits on a turntable (from a scrap irrigation reel) The sub-base is 4 x 4 timber, the base is 4 x 2, the sides 2 x 2 and the roof 1.5 x 2. The outside is lined with breathable fabric (scrounged), the inside with 3mm birch ply with 40mm celotex between the timbers and the 6 windows are double glazed units. Power is supplied via an armoured cable for lighting and power, wi-fi via the power supply. The roof is cedar shingles and the outside ship-lap boards with a protective annual coat of clear Cuprinol. It sits in a hole (drained to a nearby ditch) so the step in is minimal.I built a bench to fit cushions from an old caravan which extends as a bed (essential furnishing !) and a reclining armchair. It is sited to catch the morning sun, but is shaded from the afternoon's heat.
