Hi All,
I have been an avid viewer for the last 12 months and at last I am taking the plunge to ask for direct assistance. I have a PM who is doing my extension and supplied me with the following costs. I would really appreciate anyone's views as to whether these figures are reasonable, high/low etc. I am based in East Cork. The extension is replacing an old utility room, extending to the roof and knocking through from master bedroom to add an ensuite and wardrobe space above utility. Each room is approx 10x15, so 300 sq feet in all.

Here are the costs supplied for a 10 week build, not including vat.

Labour
Joiner = 3500
Blockwork = 2500
groundwork (demolition, footpaths all round, clearing site etc..) = 8000
Plumber = ? (2000) guess
Electrician = ? (2000) guess
Scaffolding = 3500
Plastering (removal of old plaster as well) = 15000
PM work = 8000

SUB - TOTAL 44500

Materials
Concrete = 70 cubic meters = 5000
Roof = 10 joist,tiles etc... = 3500
Sofit,gutters = 3500
Blocks = 2000

SUB - TOTAL 14000

TOTAL 58500

Thanks in advance

Looks very much in line with the kind of build costs usually advised for insurance purposes; doing the pitched roof obviously adds on, but is well worth it for future insurance purposes and re-sale value. It's worth getting multiple quotes if you can, but the one you have looks fairly sane overall though I couldn't really comment on the detailed breakdown.

The OP's quote including VAT works out at over 200 euro per sq, ft. which is substantially more than the guidelines in [broken link removed]Even though the figures are for July 06 there is still a big difference and the scs numbers also include demolition and professional fees and VAT.

Acknowledged, but note that the guidelines refer explicitly to the minimum costs that should be allowed. Plus tieing in an extension to an existing structure, breaking out through an external supporting wall, and the roof work involved, entails additional work and cost depending on the complexity. Given that, I don't think it sounds crazy.

That said, having gandered around the site a bit this morning, the plastering element looks particularly high - is the whole house to be replastered? Or is there some particular difficulty?

It's still, of course, a good idea to get multiple quotes - while it's unfair to ask seven or eight firms to go to the effort and expense of quoting, two to three should be a reasonable minimum, possibly four at a push. Asking only one - especially if they know they're the only one! - is practically an invitation to them to inflate the costs.
 
Hi Guys,

The house was originally two cottages converted in 1987. The plastering is poor on the external walls and therefore it all needs to be chipped off and replastered, hence the cost.

I agree 200 euro per sq ft is high. I was hoping for closer to 100 euro. However, each bit is quoted seperately and only when you add together does the price get inflated. I am using a PM to get good prices on labour and materials, so I think it may be time to him to go back and see what he can do.

Thanks for all your input
