What house extensions in Cottesmore usually involve
We build single and double storey extensions, kitchen and dining extensions and side returns, from foundations to a finished shell ready for decoration, with the planning route, structural calculations and building regulations sorted before work starts.
Cottesmore is a large village north east of Oakham, with ironstone and limestone cottages in the old centre and a good deal of later housing, and Kendrew Barracks, the former RAF Cottesmore, just outside it. Family homes here often want a wider drive and a lower-maintenance garden.
We cover Cottesmore (LE15) and the villages around it, including Market Overton, Barrow, Burley, Greetham and Thistleton.
Ground, drainage and conservation in Cottesmore
Cottesmore sits on mixed ground on the edge of the limestone, and the North Brook rises nearby. Drainage varies from plot to plot, so we dig a test hole before deciding between a soakaway and a permeable build-up.
Cottesmore has a conservation area covering the historic village and no Article 4 direction, so normal permitted development rules apply outside listed buildings.
The North Brook runs from Cottesmore towards Empingham and Ryhall, and Rutland's flood strategy traces its course through the village. You can check any address on the Environment Agency flood map.
