Anyone had a house extension in last 18 months?

[Madmog]

We are starting to get an idea of houses in our area, as we are about to put our house up for sale. A few of the houses, my husband has said it would be good to put up an extension. He thinks £20-25,000 will be enough, but I suspect it could be higher. So my question is, what did your extension, roughly what size was it, did you move kitchen etc. It's just to get a feel of costs.

We've just built a small utility room extension to the kitchen. Build alone cost £14k including installation of electrics, plastering and doors/window. It's a measly 5.5 m2 internally. The original intention was to replace and rehouse the boiler from the cellar but at the end of the build we were told it would work more efficiently installed in the garage so that's where it now is and we have spent a fortune on a room we now don't really need!!! Feel slightly sick when I think about what we could have spent that money on...

The problem I have had is getting builders to even quote. Sorry about your utility room.

We were told to plan along the lines of £1.5k for every square metre. This would cover build, electrics, plumbing, plastering etc but not things like flooring. Our extension (kitchen diner) as built earlier this year, size 30 square metres, and the cost came in at almost exactly £45k. We then had an new kitchen and high spec flooring put in which pushed up the price, but we always knew that would be an additional cost. Our extension also involved knocking through to our previous (very small) old kitchen, having to do some structural stuff and also re-landscaping part of the garden.
We got three quotes before we started and they all came in within a couple of £k of each other.
We're really pleased we did it, but don't know how much value it's added to the house. We didn't do it for that, we did it because it makes the house much more liveable for us as a family. We're not planning to sell for years.

We are just about finishing up a rear single storey extension of approx. 30 square metres, and it looks like it will be coming in at about 32K. The builder has been fabulous, lots of good ideas and tweaks for the better and I would happily recommend him to anyone local (Staffordshire).

Two storey side and single storey rear extension, around 60sqm. Coming in at £80k including plastering, electrics etc, but not bathrooms or kitchens or flooring. Does include painting it all out white though! We're in London. I like our builder, but we're a month behind, and a couple of his sub contractors have been crap. I think we'll come out with a good finish, but I've had to nag a lot and we're effing freezing because his sodding plumber ballsed up moving our boiler and now the boiler timer doesn't work so we can only have it on if one of us runs upstairs and turns it on. We also have to find the money to relandscape around the rear extension, because the garden is fucked. It looks like paschendale.

mummytomog does that include VAT? Our planned extension is going to be about that size and builder has quoted £105k plus vat. We are in Scotland, seems really high compared to what everyone else has paid.

About 20sq metres, including utility room, downstairs loo and extension to living space. Build costs 21K then add in plans, building control cert., plumbing, flooring, lights, decorating and cupboards etc as extra. Don't expect much change from 30K.

Two storey side extension, 2 new bedrooms plus a tiny box room more than doubled in size and a utility room. Single storey sun room/toy dumping ground at rear. No idea of size though.

Cost 50K then had to find an extra 5K due to house being on dodgy ground (contingency eaten up), that's wasn't the plumbing or electrics though. No new bathrooms or kitchen (sadly see above re contingency) and utility rooms never been fitted out. Were in Scotland too.

Agree about the garden we could have really done with getting it landscaped but had no money left so we kind of did a bit ourselves and threw grass seed down

Am very and at how cheap everyone else's seems to be. These are including vat yes? Which part of Scotland are you in sweetkitty? I'm in NE near Aberdeen which makes everything a bit more expensive but shouldn't be twice the price surely?
We def need some more quotes

Mine was kitchen extension this year, only 2.5m wide x 3m in length, so for the build side was £11.5k which included new door and window (high spec) and plastered walls. £1500psqm cost wise and I am in Yorkshire.

I paid separately for the electrician as I was having a lot of other wok done at the same time including garden lighting and outside security lights/CCTV/electric shower cable plus the LED downlighters for the kitchen.

The kitchen all in was £9k which included all appliances, ranging from a cheap beko integrated dishwasher to a £850 induction hob. Units were from Ikea. Fitter was £2k. So the new kitchen is 6m long.

We knew when we bought the house that we would convert the double garage to a playroom for the children and retain a store at the back and build a kitchen extension. It is our forever house and I have no regrets about the work we have done.

My builder was amazing and we have had him back to do other work too. Turned up every day, on time, no delays with anything. Transparent about costs etc. He came recommended.

5x2.6 extension/orangery to kitchen finished last month cost £19k - included knocking through kitchen wall and reinforcing etc, electrics and plastering.

Ours worked out to about £1k per m2 for the shell with fixtures and finishes additional to this. Our builder wasn't VAT registered so we saved a bit there.

75k to knock down existing garage, rebuild as double with 12 ft sq room behind two upstairs rooms, staircase and knock through into original house. Was vvvv stressful but love it now!

the price we paid included VAT.

Yup, includes VAT. We're in London too, so we've done pretty well I think. We've got to borrow about another £15K somehow to pay for the loft conversion to be finished, the naicer fire doors we want, the kitchen, the bathrooms, the flooring and the decking out back. I do a lot of the grunt work myself, so it does work out cheaper and our kitchen is only coming to about £3K. The loft conversion was extra and about £30K not including bathroom fitting, the flooring and moving the boiler (which was another grand).

We spent our contingency on build over permits, planning fees (who know how expensive they were!) and redoing our shitty loft conversion.

Should have said my builder wasn't VAT registered either, the way he gets round this is that I paid him for his labour by bank transfer and then paid the builders merchant directly, I also paid the double glazing company directly and the plasterer etc.

Alison I would report to get the name and number removed, it could appear as advertising which breaks guidelines.

we had a very big extension added in the last 2 yrs. 3 bedrooms, 2 bathrooms & study and an utility to the other side, plus complete renovation of the original house (very old Welsh cottage) . Stopped counting after £150k......still trying to finish the bits & bobs.

Our builder was VAT registered which was very painful on the pocket....did our work then decided to leave the business he was in with his brother & dad & go solo - out of Vat. I was well fucked off. Now only do cash in hand to the chaps who do the outside jobs.
