Rather unexpectedly the building regulations regarding loft stairs are not too onerous.
Headroom
The general rule regarding headroom is that there must be a minimum clearance of 2.0 meters for a staircase but, for loft stairs, the regulations are relaxed a little and only 1.9 meters needs to be achieved.
Because of this is there is a slope where the stairs enter the loft then the clearance only needs to be 1.8 meters and 2 meters on the highest side.
Width Of The Loft Stairs
The usual requirement regarding the width of loft conversion stairs is that they should be at least 800mm wide. But, even that is not cast in stone. If your new loft conversion has only one inhabitable room than the building regulations will allow a minimum width of just 600mm for the loft stairs.
Types Of Loft Stairs
There three main types of loft stairs; the traditional and most common type is the straight staircase although, depending on the available space, this is sometimes split into a quarter or half turn with a small landing incorporated.
The second most popular kind of loft conversion stairs are spiral staircases which can add a very stylish element to your overall design.
The third, and appropriately the last resort, are alternating step or compact stairs. But these kind of stairs can only be used if there is insufficient space to install any of the more common style loft stairs.
Compact stairs are very steep and are very unsuitable for the young and old. It should be noted that they can only be used as straight flights and that they must be fitted with handrails on both sides of the stairs.
