This shepherds hut has been used as our son's bedroom for the past 3 years. It is very well insulated from floor to ceiling and has underfloor heating installed with digital thermostat and carpet and underlay especially for use with underfloor heating. It stays really warm and cosy even in the middle of winter! The shepherds hut has two double glazed opening windows, a stable door and now has a curved corrugated roof (dark green). It has its own fuse box and is connected by a 240 volt electric hook up.
