Can someone give me a rough idea how much an extension would cost?

black-saturn

I live in a VERY small Victorian terrace house with 2 VERY small bedrooms. I have 2 children and it has become apparant that I will need to have a 3rd bedroom built very soon.

Does anyone know roughly what the cost would be? It doesn't have to be exact.

It would be an upstairs extension literally 10ft by 6ft over the kitchen (flat roof) with 1 window, 1 double electric point and one light fitting.

I have got £15,000 to spend on it but wanted to get a rough idea before I call a builder for a quote as if I don't have enough I'll look like an idiot

I have no idea about the costs of these things so please bear with me.

All useful replies will be thanked :j

To some extent It is going to depend on your location so it would be worth clarifying the area you live in. Around South Bucks it would cost 20k+ that's based on what a few friends have had done recently.

Dont forget to get several quotes and dont be to concerned about looking a bit foolish...we all do at times

I'm on the Suffolk coast.

I Live in Essex and am in the process of having 2 rooms knocked into 1. My quote was £11,000 for the conversion. This doesn't cover electrical or plumbing work. I think you'd be hard pushed to do it for £15k.

There's nothing to stop you getting a couple of builders over though just tell them you'll be getting a couple of quotes and if they're too expensive for you to manage it they'll just think you went with the other firm.

I work for a building company, for a straight forward extension of that kind of size, assuming that the foundations below the kitchen are substantial and sound enough to take the loading then you should have a little bit of change from your £15k so long as you opt to do some of the finishings yourself.

Get at least 3 written quotes first detailing all of the work included - often builders don't include for the likes of painting or decoration, making good to existing walls etc.

Also get a quote for JUST the building work and see if it works out cheaper arranging your own plumbing/electrical/plastering contractors (builders charge more for having to subcontract specialist work like this out).

I think you'll be struggling to get an extension for £15K, my utility room and conservatory cost £25K and that was built 2 yrs ago.

This is a good idea if you know plumbers etc, but can sometimes cost more in the long run if the builder is left twiddling their thumbs waiting for your guys to turn up to do something.

The foundations of the kitchen probably won't be sufficient to support another floor. I would imagine that the kitchen was added some time ago and that it was only ever intended to be a single storey extension.

In addition, building regs have changed and the requirement for foundations has probably increased since the kitchen was added. Victorian foundations - if the kitchen is part of the original building - probably wouldn't meet current regs either.

Bearing in mind you'll need brickwork & a roof and all the insulating palava, I doubt that £15k would cover it

a rough estimate on website suggested £1k per cubic metre for an unfinished extension to £1.5k per metre cubed for a wired/plastered/plumbed/painted extension

It depends on whereabouts in the country you live too. The price difference incurred by geographical location is phenomenal. I suppose I'm reasonably lucky living in the North East as it's midway between the cheapest and the most expensive.

Needless to say, the south east has the highest building costs in the country.
