    Quote for single storey ground floor kitchen extension 11th Mar 17 at 8:28 AM
    Morning all

    We've just had the first quote back for our kitchen diner extension (live down south)

    It is 6m across and 2.5m out and involves removing a small 1m extension currently on the back of the kitchen.

    Quote copied and pasted below :

    Quotation for new ground floor extension
    Building works to include:

    Ground works: includes digging out footings/ over site, new 1m x 600mm concrete footings, new drainage & surface gullies, removal of existing manhole, external matching brick work & internal block work up to roof plate height, infill brickwork to existing back door & new lintels to suit
    Strip back existing rear lean to extension for new building works
    Removal of existing external soil stack & relocation of new external soil stack to side elevation of property
    Installation of new 9x2 timber joist lift to new extension including new 22mm t&g chipboard flooring

    Installation of all plaster boarding & fire boarding to steel works to suit
    Plastering works completed to all internal areas

    Form new under stairs cloakroom Inc. door/ frame etc. to suit
    Installation only of customers choice of internal bi-folding doors (supplied by customer as agreed)

    Total price to complete all listed building works: 45,800.00

    Please note:
    Price includes all added vat.
    Price includes all waste removal & disposal.
    Price does not include supplying or installing any kitchen at this stage as agreed.
    Price does not include supplying or installing a new boiler at this stage as agreed.
    Price does not include supplying the 4x new radiators; these are to be supplied by customer as agreed.
    Price does not include supplying or installing any finish flooring as agreed at this stage (quickstep flooring options & prices to follow at a later stage)
    Price does not include any painting or decorating at this stage as agreed.

    Approximate time scale for completion of listed works:
    Please allow approximately 8-10 weeks from start to completion of all listed building works

    This is the first of three quotes from a local company. I really like the builder but with the kitchen, boiler, flooring and internal doors I'm guessing the total will be Nudging 65k.

    The house is in a cracking area - we bought it last year for just over 310k whereas a similar three bed over the road (already done up) went for 400k so our total spend will be approx 380k with carpets and decorating done.

    How does this quote look? In my opinion 10k more than I was expecting for the job but hard to tell until the quotes are in.

    That's about 300 psf, which sounds a bit high, but it depends on the detail.
    No reliance should be placed on the above! Absolutely none, do you hear?

    As GDB2222 says, 3,000/m2 sounds a fair bit even if it down South, especially since it doesn't include kitchen units or worktops, no flooring etc.
