Ok as a shed as long as it has ventilation otherwise condensation will build. Might struggle to get a bike in there straight across the body as it's only about 7ft wide. I have a 16ft luton truck body as my shed with the rear roller shutter and it's very very secure. Good storage in the luton part and decent working space. I would recommend one if you can get one, obviously not to everyones taste as a garden ornament, but as this advert shows, can be a lot cheaper than a "proper" shed.
