Cost for rear extension to Victorian end terrace in Oxford

trickyUK_2

We are looking at getting a rear extension on our Victorian end-terrace (well, its strictly speaking a semi-detached, but if you think of a 'normal' brick built Victorian terrace, its that kind of thing).

We are essentially wanting to take the rear kitchen out to the full width of the back of the house (and actually, about 1m further as we have the path running up the side of the house too). It will push out a couple of metres at the back too to give us a bit more space.

We plan to have bi-fold or sliding doors across the back and a couple of large skylights in an otherwise flat (single-ply membrane) roof. The main structural work will be in supporting the bathroom upstairs with a steel frame across the full width of this space, which is around 5.5m.

The kitchen hasn't been spec'd as such, but we have a rough layout plan of where things will be. I know that a kitchen can be a £1k or £100k, but we'll be aiming at the lower end of that spectrum - a simple 'Ikea' type installation I would imagine.

Wall construction will be rendered blockwork. Floor to be either timber or tile (or, if we can afford it, polished concrete) and we'd like underfloor heating depending upon cost.

I'm trying to get costs at the moment but not having much success, though I could just be impatient! Would a budget of £55k cover this type of build? The total area is around 36 sqm. Nothing too outrageous in the design.

You need some half decent drawings , for any half decent builder to spend time quoting you

Thanks Dan-Dan. I agree, and I wouldn't have it any other way. I was just enquiring if this budget is about right these days. Web searches throw up all sorts of rates per meter square, but I never really seem to find anything recent or local.

Well apparently , depending on where you are , people claim a figure of 1k a square meter (finished) but i think this is well out of date , looking at £1500 , obviously depending on lots of scenarios

good luck!

We're just finishing a similar sized extension near Oxford and the total cost is going to add up to roughly your budget so I'd say you're in the right ballpark

That's good to hear. How's the build going? Is it a straightforward job or any design 'challenges'?

its fairly straightforward and has gone pretty well overall but a few hiccups
main one was needing a sewer buildover agreement - would advise finding out where the drains go well in advance

The drain certainly is going to need to be moved, but as of yet, we don't know where it is. There is a patio of 450x450mm conc slabs laid in the area where we think it must be, but unless I go around lifting them all, we won't know until work begins.

Are you a local (to Oxford) builder then?

You can't do the full width of the garden as your footings will intruding into your neighbours property and you will need a party wall surveyor. If the public sewer will run under the extension your local water co will change a small fortune

Footings don't go into neighbouring property. 'Full width' is a figure of speech.

Public sewer doesn't pass beneath extension. Its the manhole cover that will need to be shifted (as and when we find it!!!)
