I'm looking at designing a spiral staircase (for a new-build). For
various reasons it needs to be possible to separate the floors the

gap in the ceiling formed by the staircase. The door would be hinged
and counterweighted, on a pulley controlled by a handle somewhere, tight
fitting and fairly heavy (for sound and thermal insulation), with a bolt
to lock it. It wouldn't be moved very often (once a week maybe),
otherwise staying fixed open or fixed closed.

As more than one other poster has hinted, there are big implications for
building regs here.... what are the "various reasons" the floors need to
be separated - can you give more information about the project as a whole?
What accomodation is on these two floors, what access arrangements and
means of escapes etc are there, etc etc?
