Extension costs and timings

[Cloudywithahintofsunshine]

I know this is a bit of a ‘how long is a piece of string’ question but just after ball parks really as I’m new to this and just starting to think ahead to finances etc.

We have a smallish three bed bungalow. We are extending on the ground floor a little way out. About the size of a single bedroom. Then adding a floor.

lots of glazing. Double doors to garden.

Any rough ideas about costs and timeframes? Like I said, just roughly to start me off. Obviously will cost it all properly but want to start getting my head around it, so any ideas or tips welcome. Thanks.

150,00-200,000.

Thanks. Holy moly! I had 150 as my top budget. Ok. Time to rethink!!

£2000 per square mete

Is that for the bit that needs foundations or the building a floor on top?

My figure was based all what people have replied to recent threads on here. Tbh in order to get a more accurate figure you need to say where in the country you are and what the square meterage if the extension will be.

I don't think I am hugely off but hopefully some.other people will come and say what they have paid recently.

Thanks. I think it probably will be around that. Things have gone up so much since we moved with the plan to extend. I can’t see it changing either sadly.

Everything has gone up so much in the last couple of years. I was quoted £72k for a dormer loft conversion earlier this year, something that would have been £40k before the pandemic.

Dormer loft conversion cost £80k. 35sqm. South east. This does include everything.

This YouTube video might be useful. He does do a lot of the internal work himself but you can extrapolate and adjust.

Thank you so much all you lovely mumsnetters never fail me. 🙏

The bit inthe ground £2k plus the bit on the top may be slightly less depending on design but is a good guide
Lots of variables on quality of fit out , kitchens bathrooms etc , flat roof , pitched roof , tiled floor , carpets etc etc
