how much money does a garage conversion cost?
Design fees range from Â£1,200-Â£2,500, plus Â£300-Â£400 for a structural engineer. A typical single garage conversion (18 square metres) would cost around Â£17,100-Â£23,900, and a double (36 square metres) Â£31,300-Â£43,300, plus VAT, depending on personal specifications. Typically, garage conversions will cost more if the original structure is unsound.
