Cheers Jookie, it is a lot of money. We purposefully bought something cheaper than the initial pricepoint we were looking at because the footprint of the house was great and in an area we really liked. The intention was always to spend the money, but I'd always budgeted £30k - £35k for it and likely would've got the work done for that had this been 18 months ago.
With the kitchen, we have all the appliances already, and all the tiles and flooring, so that price is essentially for the units, the island and their fitting. Current sink etc is fine. Our current kitchen is only a year old, installed by the previous owner to help sell the house, I'm hopeful we could flog that for £300 - £500 just for a little extra to put towards the build. The kitchen we want is about £6k, then it's going to be £400 per day for two fitters, who reckon they can fit it in 2-3 days tops. Under floor heating is something we've spoken about, but I'm not really sure of the cost and we're very much looking as if it'll be every penny of savings we have.
The structural work is part of the bulk of the cost, we're having just a partition wall put up to separate the lounge, but the wall coming out of the kitchen is a support wall, so a steel beam is going in to support.
From what you've said Jookie, it sounds like you don't regret spending the money and think it was worth it. We're looking to turn the house from a cosy but oddly dysfunctional layout to something that feels more modern and makes more sense as a space for us, with the added benefit of entertaining and hosting in a greater dining space. Plus the additional bathroom is very much needed.
