ᐅ Is a staircase required to comply with DIN 18065 or not?

Hi,

we are currently in the planning phase for our small wooden house.
Our architect wants to design our staircase according to standard 18065, but this does not match our size preferences.
We want a straight staircase with a length of 250cm (98 inches)... according to the standard, we would have to extend it to at least 290cm (114 inches). The width of 100cm (39 inches) remains unchanged.

Now to our question: Does a staircase in Lower Saxony have to be designed/built according to standard 18065?
In the technical building regulations, I found this paragraph.
Regarding DIN 18065
  • 1.
  • The introduction excludes the application to staircases in residential buildings of building classes 1 and 2 and in apartments.

I could not find a clear answer as to whether I have to comply with the standard.

At the moment, we use a space-saving staircase that is 140cm (55 inches) long several times a day... maybe everything else already seems too elaborate to us.

Maybe the way length is described here is different? Perhaps we are talking past each other?
A quarter-turn staircase is certainly not a mistake!

A quarter-turn spiral staircase is not a mistake!

By length, I don't mean the diagonal but rather the depth. Stair length over floor (VKA)... that's how it is referred to in the calculator.

A space-saving staircase is a completely different matter, and 140cm (55 inches) already sounds quite specific, like a spiral staircase.

I think it will end up being a quarter-turn staircase. It should not be too long.

Turns mainly serve to accommodate the landings at the top and bottom rather than reducing the overall length or floor space of the staircase.

Actually, I’m a bit disappointed with our developer’s consultant. They never pointed out that the staircase was too small... only the architect did.

Developer? – You are building on your own land, correct? I suspect that you mean the manufacturer or importer of a holiday home or tiny house kit, whose planning architect involved in the approval and contract process was the first to realize that the proposed staircase does not comply with the standard building regulations in Germany.
This reminds me of https://www.hausbau-forum.de/threads/kuendigung-bauvertrag-keller-erfahrungen.44947/.

I will say it only once more: If you stopped keeping things secret, you could receive constructive advice here!

Hello,

the ideal staircase has a step height of 17 cm (7 inches) with a step depth of 29 cm (11.5 inches).

The length of the staircase, or the horizontal projection on the floor, is determined by the floor-to-floor height and the required number of steps.

The house is being built with Fullwood.
Currently, the drawings are being prepared by the architect. Therefore, I am not able to upload anything yet.
The house measures 13 x 6.5 m (43 x 21 ft), with one and a half stories.

Oh, a log house… How nice!
I highly recommend that once you have the first draft from the architect, you create your own thread here. It’s important to know whether it’s your own architect or if they are from Fullwood’s partner company (and therefore familiar with all the specifics of this building method). We also have a log house, and without this forum it would have ended up as – I quote – a “dark dwarf cave,” because many things really feel different when building with wood compared to “regular” construction!
