For the architect

A house with small children -> the stairs must be absolutely safe: no feet slipping through, no falling through gaps, no climbing (no horizontal bars).

Airy stairs, not cramped, not monotonous.

Attractive balusters and handrail with an accent - style up to the architect; stair treads easy to clean.

Fire escape stairs as an accent - material up to the architect, not necessarily concrete.

There is access up to the elevated water technical area.

Mopping the stairs without dirtying the wall - should a skirting strip be made along the stairs against the wall?
