    I have had a kit staircase delivered, all seems fairly straightforward so will tackle the install myself.

    One question I do have is around what to do to the exposed metal web joists around the stairwell opening (double joists all round the opening)

    Would people normally just plasterboard over them and blend into the walls, or add a timber capping piece over the exposed joists?

    Will have stardard timber balustrade and newels around the landing area.

    Just wondering what is normally done and what people think looks best?

    I assume the top and bottom timbers ( side on ) are also exposed?
    Hi, not 100% sure what you mean. I'll take a photo tonight.

    I'm assuming the metal web joists consist of two, (top and bottom timbers), connected by metal struts at intervals.
    Where the ends of the upper floor joists, end on, finish around the stairwell opening, that opening is usually "trimmed" i.e. lined, with a solid joist against which all the web joists are butted/hung. In your case are you saying its "trimmed" with a double web instead of a solid timber joist?

    I prefer to see wood round the stair opening, a once wide board, t&g or ply capped top and bottom with wood trims, usually the bottom rail of the ballustrade sits on the top wood trim which I make the same width as the newel posts
    Hi, picture attached.

    The staircase is a cheap mdf and softwood kit with plain spindles, etc so nothing fancy.

    Let me know what you think.

    On the open side of the stairwell you can treat the vertical, design wise, by incorporating it into the ceiling below with an emulsioned finish. If the stairs are all polished wood then you can face the vertical elements to a similar finish. I've done both but on balance I think I prefer to see those verticals matched in with the ceiling below. If you do opt for a polished wood "fascia " the detail at the ceiling junction below needs to be well thought out. When I refurbished my own hallway and stairwell I incorporated an aluminium corner bead the full length where it meets the ceiling below to create a rounded detail which I like and which suits the open tread stairwell.
    You can just plasterboard onto the joists but I agree with Tony and on balance I prefer to timber line them first usually sheet material, e.g. ply that is on the open side of the stairs.
    If I'm correct it appears your picture shows what will eventually be a solid wall, i.e. the closed side of the stair. If so, for that closed side stud wall, and if it were mine, I'd line it with ply or OSB before plasterboarding. For the few extra quid it gives a good solid feel to the wall and somewhere strong to affix handrails, light fittings, pictures, etc.
    How that extra wall thickness affects your stair width measurements I don't know.

    In the situation in the photo, I think I'd plasterboard them into the wall.

    I would plasterboard down over the joists to join the wall below. can only see one side though
