what performance specification did you gave the company? what is included in this price? and what type of roof timbers are there? ex Vat I presume? will eng structural cert and Planning permission be included?I got a quote recently from a an outfit in Donabate.
Our is a large attic space - 4 bed detached house). 9 m x 7 m or so. Quote was for 23K including lots of velux.
an extension, yes? budget 1000€ per m2I'm interested in this subject. As a general rule of thumb, how much does an extension cost per mtr or ft. I do not need plumbing, just an extra room, with windows door roof etc.
seek planning [broken link removed], ensure stairs are compliant to Building regs, don't use multi-foil and carefully consider your air-tightness, also Velux locations for possible future fire escapeyes includes engineer's structural cert.
suspended attic floor. RSJ/steelwork for roofwork and suspended floor.
planning not needed as am not looking to call it bedrooms, but fire doors are included.
insulation with a performance of 0.19w/m2 U value
will pm you the name of the outfit taytoman
