timber frame costing

badger81

got the first quote back for my planned house in tipperary, (4000square feet)
with a very good level of insulation, erecting the timber frame, service battens and felting/battening as well as the slabbing package, well known company coming in at 186k including vat. how does that sound:eek:

so this is just for the timber frame, insulation & boards? they'd want to be standing over an extremely good air-tightness level? sounds a bit pricey

yep, air tight membrane fitted too for that money, it's the first of about 20 quotes i expect, plus quotes for other build methods too:eek:
thought it was a little expensive

Badger1,

Do you want to give us more detail. That price "could" be extortionate depending on what you are getting.

I got a price of under 100k for a passive spec TF 18 months ago using non plastic insulants i.e. softboard, cellulose.

That didn't include windows or the weathering board for the outside e.g. cement panel board.

My home is 3300 sq ft

Yeah, the first quote sounds extortionate based on those details.

Second sounds more realistic

For reference (and as we are allowed name companies in the pricing forum) have you tried:

(a) www.Shoalwater.ie
(b) www.Ecotimberframe.ie

I've no association with either. Heard good things about both though.

Badger,
did you give a perfromance spec (U-value and air-tightness etc) is the second company giving you a 0.13 Uv external wall ?

no specs have been discussed in the second quote but i am assured that the company can offer at least the same specs as the first. the best quote so far is from the second company named above who come highly recommended by a substantial number of people and reputation is excellent.

We built a 2100 sq ft dormer in 2005, it came with all the timber, stairs, doors, skirting, architrave, rockwool insulation, felt, plasterboard, vapour barrier and labour for 38k euro.

Did you erect it yourself for that ? What finish had you on the outside ?

Sounds expensive, but without seeing the detail, hard to say exactly.

What does 'good level of insulation' mean, exactly ?

And a bigger issue should be what airtightness level ?
