    i know this will be a very how long is a piece is string question, but looking for ballpark pricing for an extension.

    It will be the full length of our house, single story so the 'new' box on the back will be roughly 10m x 5m, taking the current middle wall out between the dining room and kitchen.

    The new back wall will have 2 lots of 3/4m bifolds with a slightly pitched roof over the new bit with 4 skylights

    I'm assuming I'd have 4 steels with 2 pillars supporting the new beam holding up the new back end of the house!

    You'll really need to get some quotes, 3 or 4..... but here's my "guess".

    Building £1.5k/m = £75k
    All your bifolds and skylights £9k
    Living down south = £10k

    Total £94k.....

    I'm doing my own at 6.5m x 6m. So a bit smaller than yours. One sliding patio door 4mx2.35m approx. 2 x roof lights, 2 windows. New drains all round house. Buying 5 oak purlins to hold up the new roof as well and these bits of oak are not cheap, plus new oak floor.

    I am doing it myself, so most of the costs will be materials. I will need a sparky, and a little labour on top, but i think i will do it all for £20-25k. That is painted finished though.

    £65k sounds about par.

    Not in Berkshire - I'd bet £94k is closer to the mark...

    No, that is how much my extension will cost for all materials etc. Not a huge amount of labour needed as doing it all myself.
