Extension cost

[Guffy]

I've got a quote for a 3mx4m extension, nothing too complicated or fancy. Assuming standard depth of founds, was just wanting to gauge if the costs fits in with the experience of others?

Have attached a pic of the back of my wee house with the design i want grafted on as a guide. have been quoted £23k all-in. Sound about right?

Sounds about right to me, I would spend a little extra and get bi-folding doors though

Would a quality conservatory be cheaper?

My mum has just had a conservatory 5m x 3m £8600.

I agree with the above poster!

Way too much for what is a consevatory.

Yes it has a tiled roof but.........

you will struggle to get that through building regs with so much glass .

The OP's proposed extension will be much more than a conservatory though, it will meet building regs and be a 'habitable' space.

As has been said though expect to need serious amounts of insulation (floor, walls and roof) to meet the regs with that amount of glass. Perhaps consider brick sides?

I concur with the conservatory comments. However, if you must go down this route I would consider timber framed windows, rather than PVCu, which would conceal and blend in with a timber frame to support the roof structure.

Unless the window's are load bearing, which is unlikely, I would suggest some form of steel framing would be required as mentioned above.

Getting it through part a and part l of building regs should be fine. I've worked on complete glass structures before and haven't encountered too many issues

It completely depends on where you live, I think.

From our recent experience, you wouldn't stand the remotest chance of getting that past Epsom & Ewell.

The quote is from probably the largest company of it's type in the Aberdeen area and having seen their portfolio, i don't foresee any reg probs at the moment.

I've just had another quote from a well known National glazing company who wanted £25k for an all-glass conservatory (inc dwarf wall). Trade prices in the Aberdeen area can often be ridiculous though.

Would love to hear some more feedback (inc costs) from people who've had something similar done or from trades-folk Will the temperature be difficult to regulate throughout the seasons, even with a solid roof?

One important point I think is whether you're planning to keep those current patio doors? If you want the thing to be open plan, then building regs will be far stricter than if you put it through as a conservatory that can be closed off from the rest of the house.

Yes you're right... part of the plan is to keep the existing patio doors though. Also keeps the dog in kitchen when i'm out too

Then he will have to introduce a glazed roof to the proposal .

If it does end up as a conservatory , with the existing doors retained, then building control will not be interested in it

The design will be as in the picture. There's one just gone up behind my partners house, slightly bigger, but the same, glazed all-round and the interior patio doors have remained.

Any other feedback regarding the cost??

Thanks for the link.. it suggests £22k, plus or minus £5k.

So maybe my £23k quote, which includes 3 new windows for the front of the house isn't too far off the mark.
