Building an Extension

anotheruser

Hi

I know this will depend on so many factors but if you were looking at building a single storey extension to extend the kitchen in a property and adding a dining room, probably 4m long by 6m long, what sort of figure would we be looking at for it? - not including the kitchen or anything, just the building.

If you had something similar, how long did it take the builders to get it done?

How long did the planning permission take?

Thanks

I built my own and it was a singlg[e story with a high slopping ceiling.
aabout 15 k for materials... and about 4 to 6 weeks planning permision... planning permsion cost me about £400 and the drawings £500 ish or you can get them cheaper if you shop around.

A friend had one done last year, single storey and without the kitchen it was 20k for permission, building inspectors, tradesmen and materials.

Thanks.

I know it depends where I am in the country and lots of other things but any sort of figure is better than not knowing.

I’ve moved your thread from the ‘I wanna’ to the ‘In my home’ board’, where it is better suited.

We were quoted 30k for everything, including party wall, drawings etc, and finished inside, i.e. plastered and flooring. That is in the south east.

We just had a similar size kitchen / living room, plus a new hall way and bathroom, demolition of existing garage and to a plaster finish came in at 40k. Im in Norfolk, my builder wasnt VAT registered and charged me labour and materials separately which kept the cost down.

^as this, demolition of existing conservatory, kitchen installed and engineered wood flooring throughout the new open plan room.

£50k included 4x5m extension, 4m knock through opening, vaulted ceiling with 4xvelux, 3m sliding doors. new utility/wc in the 'old' house too. So a few extras on top of just building a basic box.

Our house is terraced with no rear access which probably added to the cost as well.

We had a 4 x 5m extension a couple of years ago to replace a conservatory, it cost £36,000 all in. We live in Sussex.

We did need 2m deep foundations because of various large trees surrounding the property which added a decent chunk to overall costs plus we did widen the opening to the extension, raise the opening by moving the RSJ and doing a bit of internal modification (added internal bi-folding double doors). This included plastering, flooring, heating and lighting.

Estimate was 8 weeks but if I remember correctly it took over 12 weeks from starting he build...but some of that was due to us and the builder coming up with new ideas as the build progressed.
