Thanks Chappers
Had a quote from another builder, 85k+vat. This is for a shell, site clearance, foundations, drainage, cavity walls (natural Yorkshire stone, block and insulation), slab ground floor, first floor joists, all internal walls, roof with concrete tiles and waist disposal. Basically, a watertight shell up to but not including first fix.
However, I'm really waiting for couple of other contractors. I've seen their build work, impressive, and also spoken to their clients, good feedback.
Both have built many houses. One contractot has built a row of houses but only quotes for Labour only. The other builder also has built many houses and only does a complete build, Labour and material. So I can't really compare the two builders like for like. However, both of them were recommended by the quarries that I visited for natural stone.
I know how much the natural stone costs about £50 per square meters (quotes from 3 different quarries). Two quarries to get back to me for a complete estimate of the build (140mm natural stone, cill, etc).
Basically, I have a rough idea of the cost of material but I'm trying to obtain more quotes from subcontractors. I will then compare the total cost of subcontractors if i manage with a quote of fu build contractors. Would definitely prefer to go with the one contractor unless their quote is ridiculously more than me project managing.
Does anyone have a contract (for a new build or a big extension) that I can use to compare against the list that I'm using for quotes?
