Hello everyone,
We are currently looking for a suitable basement staircase for the (very small) self-contained apartment in our house. The stairwell opening measures 145 x 145 cm (57 x 57 inches), and the floor-to-ceiling height is about 246 cm (97 inches). A 140 cm (55 inch) spiral staircase would actually fit well in this space. However, I am concerned that such a staircase might not meet the fire protection requirements. As far as I understand, a basement room must have a "necessary staircase," so the widths, depths, etc. of the steps must comply with certain standards.
There is the option that the escape route from the self-contained apartment leads through the main apartment, where a proper staircase is already installed. The self-contained apartment already has a door to a basement room of the main apartment, which we intended to keep locked. If we leave this door open and, for example, equip it with a door closer, would that hopefully be sufficient?
Or is there another way to install a sufficiently sized staircase in the ceiling opening? I assume that a light well does not provide a proper emergency exit, does it?
I have attached two excerpts from the floor plans of the self-contained apartment on the ground floor and basement.
Thank you very much for your support!

Unfortunately, that won’t work. Without the staircase, the granny flat would have no access to the basement and would have to go through the main apartment.

That’s exactly why I’m saying, leave out the stairwell and give that space to the granny flat as storage on the same level. What kind of planner comes up with such premium platinum nonsense?

DaGoodness28 Aug 2023 11:35I’m not sure if I’ve understood the construction correctly, but if I have, then the spiral staircase would be the only access to the basement room for the resident of the granny flat.
How are the items to be stored down there (especially possible cabinets, shelves, or other furniture?!) supposed to be brought down?
You can’t transport anything down the stairs, can you?

And doesn’t a granny flat / secondary unit have to be at least 30 square meters (320 square feet)?If that’s the case (not sure), maybe that’s exactly the reason for the basement access?Similar topics
