@Whyisitsodifficult do not spend your contingency on underfloor heating!!! That's not what it's for
We have got off lightly so far (I think) but unplanned extras so far are
- re rendering the front and rear of the main house (I thought this was included, builder says no) - will be £2000 all in
- painting the new render - it's supposed to be white but it's not "brilliant white" and that's what I want - lowest quote so far £1000 plus £350 for scaffolding at the side of the house
- cupboard doors for the upstairs cupboards because I want cupboard doors not room doors
- launderette fees!
- cost of having coving made and fitted (I had allowed for this but nowhere near enough, I thought we would buy coving off the shelf and have it fitted by the builders)
- New fascias to be fitted to the rear of the house as they are rotten due to the felt being rotten under the roof tiles - tiles will need to be stripped off and relaid
- General repairs to the roof which are needed
I do think I may have made a massive mistake in the kitchen extension - we have a small breakfast area that has been tacked onto the rear of the house. I decided that it would be a good idea to have electric underfloor heating in there so the joists are set 15mm lower to allow for the screed etc. I've just realised that I could get an additional radiator in there so didn't need the underfloor - except that the joists (and the floor!) are now set lower than the rest of the kitchen..........
To be fair it's wired for the underfloor and the designer radiators plus plumbing will probably be the same price as the underfloor, it just feels like a bit of a mistake
Currently trying to decide on doors - we have a dining room at the front of the house and a kitchen at the rear, the wall is coming down between them. It's a toss up between getting a pair of 60" wide doors (two 30") or getting something made with inner doors and two side lights IYKWIM.
THe former is simpler and quicker but the latter lets more light through and is potentially a bit easier to use....but there's a 4 week lead time and the builders want to knock through next week....
