Vaulting upstairs ceilings

    We have a 1970s semi-D. Sadly, the roof pitch is too low for an attic conversion. I'm curious what are the options for vaulting the upstairs ceilings. I saw some house show on telly where they did this (think it was C4 Ugly House to Lovely House) and I liked it. We have a trussed roof. Can it be done? Is it outrageously expensive?

    Very difficult and expensive with a trussed roof.

    Roof trusses are designed in a specific way with all the members/components acting in unison so you can't just cut away the bottom member and leave it at that. (This is also the case for many cut roofs btw - just you asked about trusses.)

    You would essentially have to build some sort of new roof structure under your existing cut back one and that would not be easy because you'd have no horizontal member to tie the two sides together.

    It is possible of course - just not cheap!

    Thanks. By horizontal member, do you mean the horizontal part of the trusses? The part that the ceiling is attached onto at the moment? I was imagining some kind of steel beam solution running the length of the ridge but didn't think about support running perpendicular to the ridge.

    When you say not cheap, do you mean in the region of 5k, 10k, 50k? Just very roughly so I know if it's definitely off the menu for me. :)

    If you have two gables a ridge beam could indeed be part of a method of achieving what you want. Only part though. I'm wary of straying in to structural advice because some chancer will read this thread and decide they can do it themselves!

    I have no idea the size, shape, location, etc etc of your house so I wouldn't even chance throwing a figure at it but even for a small house with all that's involved you'll be in five figures. How high in that range will depend on a multitude of factors.
