This garden cabin is 16 x 12 built of 25mm thick ship lap with a 75mm internal structure internally clad (Verticaly ) with 19mm tounge and groove pine.
Fully insulated of course!! I used the reflective method (Foil covered bubble wrap) it was great to work with and preforms superb
We use it just to chill , its a great place to go to relax.
The small Wendy house along side has now been fully insulated and internally clad with plasterboard and houses a chemical loo (Never know when you might need it)
