It depends on the style and size of the conversion, but in general, a loft conversion will take between 1-2 months. A loft conversion is a substantial building project, and plans will need to be drawn up. This may add to the time it takes to complete your loft conversion.
South Brent
South Brent (population 2,822) is a huge village on the southern side of Dartmoor, England, in the valley of the River Avon. The parish consists of the small hamlets of Aish, Harbourneford, Lutton, Brent Mill, and numerous scattered farmhouses. It is five miles (8 kilometres) north-east of Ivybridge and 14 miles (22 km) east-northeast of Plymouth. On the high moorlands are several hut circles, enclosures, as well as barrows, all dating from the Bronze Age. The manor of Brent came from Buckfast Abbey from the time of the foundation of the abbey in the early 11th century. It was bought at the Dissolution by Sir William Petre, a big receiver of reclusive spoils in South Devon. South Brent was originally a woollen as well as market centre with two annual fairs. Brent Hill is the high hill just outside the village where it takes its name (Old English brant-- high). On it are the ruins of an ancient building, supposed to have actually been a chapel, and also of a windmill built concerning 1790.
