Prior to purchasing, make sure you find out what the service fee budget will be and what will that service include. Generally, in NW England the service fee budget should be between £2.65 and £3.00 per square foot, so converting that to a new build would equate to £1200 for a 1-bedroom apartment, £1800 for a 2-bedroom apartment and £2,250 for a 3-bedroom apartment.
