How Much do you think this extension cost?

united4ever

The house before the extension is very similar to mine and what they have done is pretty much what I would love to have.

I think they had the loft done too but I wouldn't need that. I am also in the North west so not Aylesbury.

Also, do you think this extension would recoup most or all of it's costs when it came to resale. Guess it depends on the street.

In particular I love how they created a decent porch but integrated it into the extension. Sick of having nowhere to put coats and shoes in my tiny vestibule.

Do you think this is overkill for a modest house?

Thanks in advance

It's not the prettiest of 'transformations' but they won't have seen a lot of change from £100k. I imagine a lot happened inside, as well as out.

Whether it adds value depends on house prices in an individual area. In the south, it's likely to.

It's only overkill if the plot can't take the house.

There's a Sarah Beeny programme, fairly recent of a couple who thought they could do very similar for £60k and ended up in six figures.

Yeah, I heard lots about costs escalating if you are not careful. Will have to look up that Sarah beeney episode.

Not so pretty I agree but the house to start with is not so pretty (looks like a 60s build - same as ours) but the extension seems in keeping with the style of the original building at least which I think is sensible rather than trying to pretend it is something otherwise which would look silly on a street of modest 60s houses (assuming the neighbouring houses are similar).

DG has more knowledge of this than I do, but I'd expect that to cost half that to complete.

Depends absolutely on area; for example in Barrow in Furness in the NW, 2 bedders start around £60k and 4-bed homes from £100k, so by implication, each extra bedroom's worth £20k.

But here in SE London, an extra bedroom costs anything from £100k up to half a mil'- Whereas rebuild extension costs are only half as much again again, or at worst, twice the price of builders in the North...

Which is why it's worthwhile that beestard developer opposite me buying a bungalow for £750k to knock it down and build two semis with 6 metre deep double basements...

But maybe not worth spending £50k to add two beds oop norf. Madness

Sure, location is key. I am in Altrincham (SW Manchester) which is not Barrow in Furness price levels but way off the South East of England prices too. Whenever I ask anyone about extension costs it always location specific. Is that just labour costs varying across the country? Could do with some sort of price map of where is cheap and where is not, would I be right in saying the costs of extension generally follow the house price levels?

No. Cost of extension does not follow house prices. Slightly, but they're not relative.

The cost of raw materials is similar wherever you go. Labour is cheaper outside of the South East and the cost of disposing of waste is cheaper outside London.

Even in a small area, builders quotes will vary on the same project. All projects are different with different engineering challenges and costs.

This isn't just an extension. Even without a loft conversion, a considerable rewire, new boiler, additional plumbing and structural support and re-configuration inside would be required to bring about a workable layout. New kitchen, no doubt and at least one brand new bathroom.

Builders don't sell apples. You can't compare very easily.

Have a look at the homebuilding and renovating website. They have a build cost calculator, however - there will be no VAT in those prices and extensions are more expensive to create than new houses. The build style and shape of the house you link to is not a cost efficient option in terms of the ratio of building carried out to space gained.

In Altrincham proper (less convinced by broadhealth etc) it's worth doing IMO

Buy a copy of 'Homebuilding and Renovating' (or look at their website) for their housebuilding price-calculator; prices psqM factored by region and quality of finish

This is an interesting thread for me - we're about to embark on a single storey extension to our property.
We're adding approx 23 square meters - and including a significant remodel of the existing layout and re-wire of the entire property, plus 2 bathrooms and a kitchen.
We live in the SW - currently the likely cost is looking to be around £70k. We're certainly not going for a top spec level of finish either.

We hope tht the extension will add value - but whether we will re-coup all costs in-terms of an increased valuation I really dont know. We're extending to live in the property - so the future value of the house is a little irrelevant tbh.

I see, will have a look at the homebuilding and renovating website. In general though what is the most cost efficient extension option in terms of ratio of building to space gained? Would it be a two storey square extension....unlike this one which wraps around the front and back? Thanks for your advice.
