Building in Donegal, blockwork for house and garage, 2700sq ft. total was 10,000 cash.
Plumber including oil burner and underfloor heating quoted 10,000
Roofer and carpenter quoted 17000
PVC windows and doors 14000
Electrician 10000 incl. chasing and supply of downlighters, my spec was higher than the norm.
Natural slate, I need 8000 approx. and price is varying between 1.70 - 2.50 ea excl VAT
I took out self build insurance with Wright insurance, they were the cheapest at 3000
These are the only prices I have at the moment, hope they help.
