Hello, we have a garage attached to our house (added on prior to our purchase). We have created a shower/toilet room in the rear corner of the garage for use from the garden. There is no access to the house from the garage or shower room. When you enter the garage from the garden there is a door to the left into the shower room and a door straight ahead into the garage. We are being told by building control that the door straight ahead into the garage needs to be a fire door, is this correct? Many thanks

Seems a bit over zealous as it isn't actually the house, just a lobby with a shower off, an area infrequently occupied and not sleeping risk. Ask them to reference the relevant paragraph of Approved Document B they are using to determine this requirement.
