Choosing your Loft Stairs

When designing loft stairs, it's important to consider whether you'll need a SpaceSaver staircase or whether you can accommodate a compact, standard construction staircase.

There are lots of options available to help you create a staircase perfect for your space. You can design online using our StairBuilder® tools and try out different configurations to find the best solution. Alternatively, you can get in touch with our team who'll be happy to help.

SpaceSaver Loft Stairs

A SpaceSaver staircase, or paddle flight, has alternating staircase treads which means the stairs require far less going – or horizontal floor space - to get to the same rise compared to a normal flight.
However, SpaceSaver stairs also have additional requirements within Building Regulations which can limit their use, so it is worth considering all of your options before making a decision on your loft stairs construction.

Standard Construction Loft Stairs

With careful planning and design, it may be possible to access your loft conversion via a standard construction staircase. Utilising turns and winder treads, a staircase can fit into a compact space whilst still meeting Building Regulations.
It's especially important to watch out for head height problems to make sure your new loft stairs are fully compliant.

A SpaceSaver staircase, also known as a paddle flight, has alternating treads which means the stairs require far less going – or horizontal floor space - to get to the same rise compared to a normal flight. You can find out more about our SpaceSaver loft stairs here.
We don't offer spacesaver loft staircase with a turn. Spacesaver loft stairs are normally used when there isn’t enough floor area to accommodate a standard staircase, and so a straight spacesaver flight is the only option.
You can shorten the overall length of a spacesaver staircase by using fewer treads in the design. If you want to make the staircase longer, you can add more treads in. To ensure you stay within UK building regulations we don’t allow you to modify the individual tread depth on the Loft Stairs Designer, we can only manufacture within the set parameters on the design tool for this type of staircase.
We can only offer balustrade on one side of your loft staircase, the other side would need to be fitted against a wall.
A SpaceSaver staircase requires less floorspace than a standard construction flight. However, SpaceSaver stairs have additional requirements within Building Regulations (as per Document K) which limit their use. Therefore, if you have sufficient space available to satisfy Building Regs, we would always recommend opting for a compact standard construction staircase as opposed to this kind of loft stairs.
If using our online Loft Stairs Designer, our SpaceSaver stairs are made of pine with birch plywood treads and risers; posts are square with flat post caps, spindles are 41mm square and rails are Cheshire Pattern. However, if you would like a different spindle, glass balustrade or oak posts, please contact our team who will be able to provide a quote.
All of our stairs are sent out pre-sanded but unfinished, for you to apply an oil or paint colour of your own choice.
We don't offer an onsite measuring service, however there's a lot of information about measuring for your staircase on our website. You can then transfer the dimensions to our online Loft Stairs designer tool to create your design. Our team are also extremely skilled at offering assistance over the phone and will be able to help you find the required measurements.
We currently deliver to mainland UK only, however in the past we have shipped to ports for customers to then arrange their own onward shipping.
All staircases are manufactured to the exact sizes shown on the Loft Stairs Designer, however as timber is a natural product it can swell slightly in different temperature and humidity conditions (usually around 5mm in the width). We always recommend leaving an additional 10mm surrounding your staircase for fitting purposes.
