This is water tight and we currently use it for storage. Would need some TLC to be made suitable for living in.

2 x bed

1 x toilet and shower room

1 x kitchen with oven, sink and fridge

1 x lounge area with French doors

Gas boiler

All the gas and electrics worked when we bought our house, this came with it Jan 2020, however it was soon all disconnected so can't test or guarantee.

Thanks for looking.
