In order to file my building control papers I need to know the estimated cost of the work (the BC fee depends on this). Even if I DIY most of it the fee is still based o nthe commercial cost of doing the work.
Can anyone suggest a good place to get acceptable (to BC) estimates per square metre for simple jobs such as
"rebuild a single story external wall" "lift floorbaords and install insulation under" "remove concrete floor and install suspended timber floor with insulation" "replace slate monopitch roof".
I have to do this for each of the "thermal units" I intend to interfere with :-(
For example, would Brinkley's "house builder's bible" be a good book to buy?
many thanks for any suggetsions,
Robert
