In order to comply with building regulations, your loft has to be a minimum of 2.4m or 7’8″ at its highest point (i.e. the apex of the roof). Those measurements are taken from the top surface of the ceiling boards below to the felt at the very apex of the roof. With that in mind, we can make the most of even the smallest lofts with the imaginative use of dormer windows and staircase positioning.
