Extension costs
when it proposed to have a rear extension to your home to convey any extra space is important to generally have some kind of budget in mind as to the costings as they would appreciate that obviously have extensions are a costly but affordable to have the correct budget in place
most building contractors charge approximately per square metre so if you extension but they say 4 m projection by 5 m width this would give you an internal floor area of 20 m² on average we would surmise about £1200 per square floor metre area and this will give you an approximation of your costings for your home extension
