When deciding on what stair design best suits your property, the often fiddly and confusing Building Regulations can turn a dream do-over or DIY renovation into a logistical nightmare. The team here at British Spirals & Castings can help walk you through these requirements as we design your staircase, but we know some customers like to get their head around these rules before getting in touch. One of the key considerations is how wide your landing needs to be and how much free space is needed at the top and bottom of the staircase.
Under current guidelines in England, Scotland and Wales, the top and bottom of the stairs are effectively treated as a landing. This means there must be clear, unobstructed space at either end of the flight so you can get up and down the staircase easily. The particular requirements will depend on your building type and the spaces served by the staircase.
For all buildings:
- In all cases, stairs must have landings which are at least as big – in length and width – as the width of the flight. This will need to comply with the minimum widths set for the particular staircase type. For example, if the stair width is 1000 mm, then the landing must be at least 1000 mm by 1000 mm in area. The diagram below shows how this works.
- The landing should also be kept clear of permanent In England and Wales, doors to cupboards or ducts may open over the landing in England, provided they are kept shut/locked in normal use and still provide a minimum clear space which is at least 400 mm deep (as shown below). In Scotland, this is only allowed on private staircases (those within homes).
- Landings should be level. They can only have a gradient if the surface is firm and the maximum gradient along the direction of travel is 1:60. This means that for every 1 unit of rise or fall, there should be 60 units of landing. This is more likely to occur in external situations.
In England, Scotland and Wales, it is possible for a door at the top or bottom of the staircase to swing across the landing providing a minimum clear depth of at least 400 mm is maintained (as shown below)
In non-domestic situations, there needs to be a bigger space on the top and bottom landings than in domestic dwellings. The reason for this is simple, these flights. Will serve more people than one in the home and there may be people moving in both directions on the staircase at a given time.
- There must be an unobstructed clear depth of at least 1200 mm on each landing.
- In England and Wales, doors may only swing across landings when they are shut/locked under normal use. In Scotland, doors must not swing across this space.
If you live outside England, Scotland or Wales, you will need to check your local Building Regulations to confirm the exact requirements.
