What house extensions in Ketton 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.
Ketton gave its name to Ketton stone, the cream oolitic limestone quarried beside the village, and its older streets are built of it, many under Collyweston slate. Around the historic core are later 20th-century houses and bungalows, and the cement works and quarry sit on the edge of the village.
We cover Ketton (PE9) and the villages around it, including Tinwell, Collyweston, Barrowden, Tixover, Aldgate and Geeston.
Ground, drainage and conservation in Ketton
Ketton is on the Lincolnshire Limestone, which usually drains well, but the River Chater runs through the village to meet the Welland, and ground close to the river is a different matter. We test before designing a soakaway.
Ketton has a conservation area covering the historic village but no Article 4 direction, so normal permitted development rules apply outside listed buildings, with the usual conservation area limits. Ketton stone frontages call for buff and natural tones rather than grey.
The Welland flood warning area at Ketton is the only Environment Agency flood warning area in Rutland, and Rutland's flood strategy names Ketton among the places with a few properties at river flood risk. You can check any address on the Environment Agency flood map.
