Thornaby's mixed stock
Thornaby grew in layers: interwar semis around Mandale and the older town, post-war estates through Thornaby town centre's surroundings, and newer infill towards the Tees. The interwar semis are the best conversion stock, traditional cut roofs, decent head height, and hipped examples that suit hip to gable at £40,000 to £55,000. The post-war stock takes standard rear dormers at £30,000 to £50,000 where the ridge height clears 2.2 metres.
Prices in Thornaby
Standard Teesside rates: Velux conversions £15,000 to £25,000, dormers £30,000 to £50,000, hip to gable £40,000 to £55,000, boarding for storage £1,000 to £3,000. Thornaby's house prices are among the most affordable in the TS area, so the conversion maths often focuses on staying put rather than moving: a dormer adding a fourth bedroom commonly costs half what the equivalent move costs once stamp duty, fees and the price gap are added up.
Watch for in Thornaby
Some of the later estates use trussed rafter roofs, which add £3,000 to £6,000 of structural redesign to any conversion, check the loft for the tell-tale W-shaped timbers before budgeting. Party wall notices apply on semis and terraces as everywhere. Building control runs through Stockton-on-Tees Borough Council.
