Plenty of homeowners spend months planning a loft conversion or a mezzanine extension only to run into the same unexpected obstacle, the staircase. It seems like the simple part of the project, but a traditional flight of stairs eats up far more floor space than most people realise. Often four or five square metres of the room below and once you start drawing it on the plan, the dream of a usable home office, guest bedroom or extra living area suddenly looks a lot tighter.
If you have been through this and felt your plans shrink in front of you, you are not alone. The staircase is one of the most common reasons that loft conversions and mezzanines either get scaled back or quietly abandoned. The good news is that compact staircase design has come a long way in the last few years, and there are now properly engineered options that solve the footprint problem without forcing you to climb a ladder to access your new space.

How small can a real staircase be?
The 1m² staircase made by EeStairs occupies a single square metre of floor and ceiling space. It is not a gimmick or a ladder dressed up to look like a staircase. It is a properly engineered spiral stair that complies with building regulations for secondary access, which is the relevant category for lofts and mezzanines.
The clever part is the structural design. The staircase is built around a subtly slanted central column, and that slight angle is what allows the treads to be wider than they would be on a strictly vertical spiral. The result is a stair that feels and works like a proper staircase rather than something you must climb sideways. It is built in high-strength steel and has a tested load capacity of up to 300 kg, so it will comfortably handle daily family use, furniture being moved up and down, and visitors of any size.
Designing it the way you want it
One of the more useful things about the 1m² staircase, for a homeowner planning a renovation, is how flexible the specification process is. Rather than going through weeks of bespoke drawing rounds, the staircase is specified through an online configurator. You can put in your floor-to-floor height, the direction of the spiral, and the finish, and see a 3D model and a costed quotation in a single session. A technical drawing is then produced for approval, and the staircase is typically delivered or installed within about five weeks.
There are over 200 RAL colour and finish options, and you can choose clockwise or anticlockwise configuration depending on where the entry and exit points work in your space. That matters more than people expect, getting the spiral going the right way for your floor plan can be the difference between a stair that feels natural to use and one that always feels slightly awkward.
Staircase design specialist Oliver Schneider describes the configurator as a way for homeowners to visualise and personalise the staircase without losing any technical accuracy. For anyone who has been frustrated by trying to imagine a stair from a flat drawing, the ability to see a 3D version of your actual staircase before committing is a significant practical benefit.
What installation looks like
The installation is where the staircase often surprises homeowners. Two trained installers can put the whole thing in place in under two hours, using standard tools. There is no need for cranes, scaffolding or heavy lifting equipment, and there is no structural intervention beyond the floor opening that has already been prepared. For anyone who has lived through a renovation, that level of disruption, two people, no major mess, is genuinely unusual for something as significant as a new staircase.
It is also why the staircase works well in homes that are already occupied or already finished. You do not need to clear out, you do not need to re-decorate the rooms below afterwards, and you do not need to lose access to the rest of the house for days at a time. For a family planning a loft conversion in a home they are still living in, that practical reality is often the difference between going ahead and putting the project off.
Building control and the practical questions
Most homeowners worry about building control sign-off when they are adding a staircase, and rightly so. The reassuring thing about the 1m² is that it has been engineered to comply with building regulations without needing project-specific approvals or special arguments to building control. Your architect or builder will be familiar with the category, and the compliance side is settled before you start.
That does not mean every home is automatically suitable. The staircase still needs the right kind of opening, the right floor-to-ceiling height, and a sensible position within the room. But these are normal questions for any staircase, and the configurator and a short conversation with the manufacturer or your installer will tell you quickly whether it works for your space.
Reclaiming the room below
The reason engineered compact staircases like the 1m² have caught on is straightforward. They give homeowners back floor space that would otherwise have disappeared into circulation. On a small loft conversion, recovering three or four square metres of usable area means the difference between a cramped guest room and a comfortable one or between an extension that works and an extension that always feels too tight. For homeowners weighing up whether a loft or mezzanine is even worth doing, that reclaimed area is often what tips the project from “not quite worth it” to “absolutely worth it.”
If you are at the planning stage of a loft conversion, mezzanine or compact extension, the staircase is one of the first things to think through and one of the first places where small design choices have outsized effects on what your finished space feels like to live in.
