We are planning to convert our garage. Currently we have a fire door into the garage as it’s attached to the side of our house and can be accessed through the kitchen. 
However, we plan to convert the garage into an office. Does this mean we will not need it to be a fire door anymore as it will no longer be a garage but will be a habitable space as part of the home? 

Hi Amy,

I would contact your local building control for advice, conversion of a garage into habitable space will normally require approval under the Building Regs.
