mark@mbb Posted July 28, 2014 Report Share Posted July 28, 2014 if you shop about £750 m2 is more the norm at the minute Quote Link to comment Share on other sites More sharing options...
JBS Posted July 28, 2014 Report Share Posted July 28, 2014 if you shop about £750 m2 is more the norm at the minute Not on 8m2 unless you want a **** job, 750 a meter is 10 years out of date Quote Link to comment Share on other sites More sharing options...
mark@mbb Posted July 28, 2014 Report Share Posted July 28, 2014 The prices around me are going for less than that and if you own All your own kit that price is not a bad price Nothing has moved in the building trade for while Except people getting greedy as a rule if thumb The price before the recession around here Was £1000 m2 and they were good prices Quote Link to comment Share on other sites More sharing options...
The Mighty Prawn Posted July 28, 2014 Report Share Posted July 28, 2014 Got quoted 18 to 20 for just over 18m2 recently and that seemed average for the three quotes, was literally only hundreds in it Quote Link to comment Share on other sites More sharing options...
brynhaller Posted July 28, 2014 Report Share Posted July 28, 2014 Yeah right ! £6k for an extension ,if you can do it for £750 m2 you can do em all day for us,an we will go shooting or fishing,it'll cost best part of £1500-£2000 just to knock conservatory down and dig out the more than likely inadequate footing and slab!

RED BEARD Posted July 29, 2014 Report Share Posted July 29, 2014 We are waiting for a price on 19' x 13' lean to conservatory at the moment, so I'll let you know. I'm having to prices, one excluding moving the manhole and digging and pooring the footing, if they want a fortune for that I'll do it myself.

Chris Bb Posted July 29, 2014 Report Share Posted July 29, 2014 We have a single storey extension on our house (built about 35 years ago) that I've been considering converting to double story, i.e. bedroom & bathroom upstairs. Local rumour has it that the foundations are not up to taking a second storey. Is this likely to be true? How do I find out? Quote Link to comment Share on other sites More sharing options...
mark@mbb Posted July 29, 2014 Report Share Posted July 29, 2014 Brynhaller if it costs you 1500 to 2000k to knock down and clear the site you need to be looking somewhere else for work mate invest in a couple of small diggers and maybe the odd cherry picker and you will be amazed how much you can shave offf your prices and we have lads that have worked for us for 20+ years doing the same things we own all our own tackle vans diggers and every thing else and we do make it pay and keep people happy Quote Link to comment Share on other sites More sharing options...

Local rumour has it that the foundations are not up to taking a second storey. Is this likely to be true? How do I find out? dig a hole on the outside of the extention and see how deep the footings go or retreve the original plans from the council and have a look I think you will find the planning officer will ask you to dig down for him to check anyway Quote Link to comment Share on other sites More sharing options...
Del T Posted July 29, 2014 Report Share Posted July 29, 2014 We had one done about 2years ago. Roughly 3 meters by about 2meters,sloped roof with velux window, French doors on the back and window at the side Paid roughly 9k for it. The bricks were dear bricks too as they are hard to match .

Nial Posted July 29, 2014 Report Share Posted July 29, 2014 We have a single storey extension on our house (built about 35 years ago) that I've been considering converting to double story, i.e. bedroom & bathroom upstairs. Local rumour has it that the foundations are not up to taking a second storey. Is this likely to be true? How do I find out? Grab a spade and find out. We're about to extend the house, the architect said in passing that it would prevent any nasty surprises if we knew how deep the current founds are and that it would only take a couple of hours with a spade. 4 Hours later I discovered they're 1200mm deep. Then remembered I have a pick in the garage, I'd struggled through with a fork and spade. Eejit. Nial Quote Link to comment Share on other sites More sharing options...
tonker Posted July 29, 2014 Report Share Posted July 29, 2014 Down here in the South west, the cost is £1500+ a square mtr for building. it hasn't moved much in the last 5 years. That is obviously finished and decorated. That's what I've been charging anyway, and I've been self employed for 36 years. and I've always been lucky enough to have a years worth of work in front of me, so I can't be far out with prices. (but they are all done by a QS) Quote Link to comment Share on other sites More sharing options...

Longchalk Posted July 30, 2014 Report Share Posted July 30, 2014 (edited) W e have a single storey extension on our house (built about 35 years ago) that I've been considering converting to double story, i.e. bedroom & bathroom upstairs. Local rumour has it that the foundations are not up to taking a second storey. Is this likely to be true? How do I find out? We do these geo-technical investigations for living. A few exploratory hand dug pits are probably required. You need to know not only the foundation design & depth, but also the materials used. A bit of clever engineering number crunching will then give you a 'bearing capacity' of the existing foundations. This can then be used, taking into account what you want to add on top, to determine if your current foundations are adequate or not.... Just dont ask me to work it out, I just do the invoicing & credit control! Edited July 30, 2014 by Longchalk Quote Link to comment Share on other sites More sharing options...

It's only a single story. Depending very much on the facing brick and roof tile required by planning £10 - 12 k plus Vat. Or cowboy prices £8 - 9k Cash. You might be lucky it might come under permitted development but have a word with the council first. Hope this helps. Quote Link to comment Share on other sites More sharing options...
Del T Posted July 31, 2014 Report Share Posted July 31, 2014 Or cowboy prices £8 - 9k Cash. Hope this helps. Mine was a touch over 9k and its far from a cowboy job. The building inspector wouldn't have passed it if it was. It helps that the builder is a dab hand at doing joinery,digging footings,brick laying, etc etc. You can save quite a bit by not involving loads of different trades. And I am in the building game, (plumbing& heating engineer). Quote Link to comment Share on other sites More sharing options...
Twistedsanity Posted July 31, 2014 Report Share Posted July 31, 2014 I had a 3m x 4 m extension built 2 years ago, excluding the cost of the glass I paid £8k plus the vat , that was cheap as it s a family friend. Quote Link to comment Share on other sites More sharing options...
