Building cost per sq m?

[BERGS2]

Hi All -

We have been looking at a side extension and loft of approx 40 sq m

Have just had version of the plan where this is extended to 50 sq m

do the rough costs per sq/m remain similar? One of the guys we've had round to give beermat costing said work to roughly £1600 /sq/m - so one that basis, 40 sq m would be £64k & 50 would be £80k.

i know these rule of thumb number are sketchy at best - but was wondering if someone in the trade has a model that helps accuratly scale?

(the extension will be rendered block - below in blue is the 'new' area)



Cheers Y'all

Anyone?

We're in the south east- & will be aiming for a nice, but not super high spec...

Have crunched a multitude of excel sheets on the matter - but real world numbers alway good points of ref

I know the figure is in the right ballpark but in my experience some builders and QS's are starting to edge towards figures which would mean it's barely viable to build anything at all these days.

do you mean viable as in getting back the monies put in?

I can never tell if we're being mugged off - was surprised by the number of builder / build co's who genuinely didn't seem interested - or took the time to have a look and the didn't come back

It seems like an odd coming together of factors:

Housing market cooling - Transaction volumes down, so more people 'staying put'/ extending rather than moving
Broad materials inflation
Economic uncertainty

Some of the builders we've spoken with say that the volume of work is way down - other said they could schedule in our works just before Christmas..... Is this a polite way of being told to bog off?

if you are looking for a quality job that will be completed in a timely manner by a company who offer a good service I would say that your project will cost nearer 100k

Cheers josh - just out of interest - how much do factors such as site accessibility and build type impact on typical pricing?

Our place is/will be rendered block - which the 'tect says should be cheaper, similarly - we're on a flat wide plot with easy access from all sides. are these marginal considerations? Or, could they change things by a few quid per sq m?

our budget is £125k but thats 'all in'

what's happening to insulation costs then?
