I see that you looking spiral staircase... We can make for you most original wooden spiral staircase in Norway. You can check our web site (www.staircase-interiors.com), also, you can send me email (stairs.interiors@gmail.com) and I will replay you with picture of stairs that Im talking about.
I write to you from Croatia, but if we can have a deal about stairs, there is no problem to come in Norway and install them...
This is my proposal for our product, but you can also send me on email draft of your vision that you describe above. I will give you the answer with pleasure..

Very nice staircase indeed, Bozidar! Wish you luck in Norway and elsewere.

Mitt forslag er å søke på nettet og finne et firma i Norge.
Det er flere firmaer som leverer vindeltrapper i metall. Det er ikke nødvendig å sveise noen ting. Alt skrus sammen.
Men man må jo da tåle å leve med en vindeltrapp som er en metallkonstruksjon og som ser ytterst annerledes ut enn den snodige konstruksjonen som er avbildet ovenfor.

Jeg var heldig og fant en på finn.no til 5000,- som passet i høyde, laget bare en plate nede som nederste trinn. Opp mot 50 000 var ny pris. Her er det en søyle som går over rekkverket øverst. En trer på trinnpå denne søylen og monteres med spiler, trer på alle trinn før en monterer spiler opp mot rekkverket. Ene spilen går gjennom trinnet over før den går ned i trinnet under og låser ting sammen.

Det finnes mange mye billigere trapper på markedet men en del tåler kun 200kg maks belastning. Dvs det må aldri mere enn to personer i trappen samtidig. Siden jeg skulle ha nødutgang var dette utelukket løsning.

Very nice staircase indeed, Bozidar! Wish you luck in Norway and elsewere.

Nice sculpture, but does not meet the requirements for stairs in the Norwegian building code. Handrail is required on both sides, and the steps seem to be to narrow.

Hand rails on both sides? Google vindeltrapp pictures, you get numerous hits from norwegian sites, none of which seems to to have two handrails in a single helix staircase. Not according to code, but normal practise?

In my home, there are two stairs with only one handrail (outside at the front door, and between the two main floors), and two with none (attic and basement). Probably legal according to current codes when they were built 47 years ago, but not under TEK10 and TEK17.
I guess one would have problems getting approval for a new home where a helix stair with only one handrail, or a fancy minmalistic designer stair with steps fixed to one wall and no handrails, is the only access between two inhabited floors. Or a new stair in a old home that does not meet current codes.

@Bozidar: It is not my intention to critisize your beautiful stairs, but it may be worth checking the legal requirements in different markets to find the best solutions that combines good design and security and accessbility requirements. Norwegian building codes may be a bit strict...
