What Counts as a Third Storey for Fire Regs?

Can I ask what is classed as a third storey. If we have roof access via a small porch is that classed as a room for Fire regulations?

    Hi Marie,

    Your ground floor, first floor and second floor would be considered: ground, 1st and then 2nd floor. From a surveying perspective, we do not count the ground floor if it’s level with all sides of the external walls.

    In your case, the space in the roof would have to be a habitable one to be classed as such.
