Loft Conversions for Glastonbury Homes
Glastonbury is a town of genuine character and variety — from period stone cottages near the High Street to more modern housing on the surrounding estates. This mix creates a range of loft conversion opportunities. JM is sensitive to Glastonbury's unique local aesthetic and designs conversions that suit the town's character as much as the individual property. Whether you're in a Victorian terrace near the town centre or a 1970s detached on the outskirts, JM will find the right solution for your home.
Planning Authority: Mendip District Council
Property types: Mix of period and modern homes
