We went as far as getting the company surveyor in to ok the position of a detached wooden garden room before I woke up one morning and decided we needed an attached house extension type garden room.
It really is brilliant and the room we spend most of our time in.
It has a glass gable end and sticks out into the garden so winter or summer you feel part of the garden. And of course it has heating and is a few steps away from in house facilities.
It also has a solid insulated roof so no super high temperatures on a sunny day and comparatively less glass area than the conventional pvc conservatory.
We really had our hearts set on the detached shed style room. The one I really liked was a round hobbit style one with a green roof. It was bespoke and would have cost more than the house extension one we eventually had built.
Down sides to the shed style are just the practical side of things.
Heating (wood stove?), lighting (armoured cable extension?), what do you do for a cup of tea (add a water pipe?), heads (bucket and chuck it?), trailing wet feet into it in the depth of winter after the cold windswept walk getting the froth blown off your cappuccino.
I just reminded myself why we didn’t get one.
