Stairs for loft conversion

Get an architect to come round and give you a quote You don, t have to pay and at least you,ll have an idea of where its best to go.

Then go online to someone like stairbox and input your dimensions etc and that will give you a price .

Staircases fall under part K regs, this includes hand rail heights, going/rise (the tread distances), head heights min landing sizes, widths etc its a long involved document. There are tricks to gaining headlights like Velux windows over the stairways, half landings gain room when tight but it really is what works best with your layout.


There's no real knocking up of staircases a CNC machined MDF staircase will be the cheapest option.


Custom staircases cost fortunes, I built them for my place myself x2 proberbly 100hrs work + if I was pricing the work you would be in the realms of 5 figures+VAT Each.

You will see all sorts of staircases in fancy loft conversions, but many of those are not classed as loft conversions but non-habitable rooms in the roof space. Legally you cannot use them for bedrooms and estate agents cannot include them in their description of the property. You might also get prosecuted for breach of the Building Regulations.

I would go for an old fashioned staircase designed by an architect or an experienced architectural technician and built by a traditional small builder or experienced joiner or handyman. The one shown in Snowcat75's post has a turn in it. However when going for open tread stairs like this remember the traditional staircase can have valuable storage space under it.

A simple staircase with a turn in it is probably going to be the staircase that takes up least room. Spiral staircases may look compact, but ones that meet the Building Regulations can take up more room than a simple traditional staircase.

Part K does make some allowances for loft conversions, over new builds it also is slightly ambiguous on certain points using terms as "Its advisable" rather than must. The main thing BC wants on domestic sets is correct going and rise, "sensible" head heights and no breach on the 120mm gap rule.


My staircases wouldn't suit a normal dwelling IMHO I designed them as a one off for a barn, Likewise I thought standard domestic sets would look stupid ironically though although the scale of the place is big, It was still a struggle to fit and design the staircases to work and that complied with regs, I was about 20mm under on the head height and 60mm two narrow on the half landing, however building inspector new it wasn't a corner cutting exercise just how it had to be so allowed it to be.


As for storage long term I'm going to build some cupboards under the half landing just not sure on what materials to use yet, I'm a fan of spraying MDF for ultra shine modern finishes I'm yet to convince Mrs Cat that what she wants though!, luckily im in the position that I can make/build most things myself labour and bespoke=£££££.

We had a few problems with the staircase when we converted our bungalow to a chalet bungalow. Not just a normal conversion as the whole roof and rafters had to come off - there was a groundfloor extension too. We had the choice of putting the staircase in the living room, dining room or utility room We decided on the utility room as I didn't really want it in the others.


Because of the space they allowed us to have the each stair slightly narrower (very slightly lol). We also had to make the headspace better by putting a slanting bit on the ceiling of the lower bit of the stairs. Had to change it because the original inspector had allowed what we had but on the final inspection we were told that it had to be changed. The original paperwork didn't go through for some reason!!!!! Anyway bearing in mind that my son is 6ft 3ins and he never had any problems with it seemed a strange rule to us.

The paper plans and reality are often different
