New garage stairs

[brycheiniog]

All,

I am fortunate to have a decent sized garage which I was lead to believe by the former owners was constructed with the idea to create a home office above. At the moment access to the upstairs is via a very dodgy steps/ladder which for all sorts of reasons need to go.

I don't really have the cash at the moment to get a bespoke galvanised external staircase made, and have been pondering installing an internal staircase instead installed into the rear RHS.

Type of staircase I am thinking off:

I guess the first question is would I be daft to do this. It will loose some space in the garage and some floor space above and create an opening from the garage to the loft space.

One of the issues is that I would need to cut one of the joists to form the new stairwell. The existing joists are 47x200mm with a 52cm spacing. From some googling it looks like cutting one wouldn't be a problem as long as the ends were suitable braced with a new trimmer and the remaining joists either side were doubled up as per Fig 4.2 TRADA Span tables

I'd do that, sell the house and live in the garage

Double up the trimmer as well
