What hot tub & swim spa bases in Kettering usually involve
A filled swim spa can weigh as much as several cars on a small footprint, so it needs a reinforced concrete slab built to the supplier's published requirements. We build the base, the drainage and the access so the unit can be craned or wheeled straight in.
Kettering has Victorian and Edwardian terraces and villas close to the centre and along the Headlands, interwar and post-war estates, Barton Seagrave to the south east, and Hanwood Park on the east side, planned for up to 5,500 homes.
We cover Kettering (NN15 and NN16) and the villages around it, including Barton Seagrave, Burton Latimer, Geddington, Broughton, Cransley, Pytchley, Rothwell, Desborough and Mawsley.
Ground, drainage and conservation in Kettering
Ground around Kettering ranges from ironstone to clay, and new-build plots are often compacted subsoil under a thin layer of topsoil. We check what is under each garden before choosing the base and the drainage.
Kettering has 26 conservation areas, including the town centre, Barton Seagrave, Burton Latimer, Geddington and Rothwell. Its Article 4 directions are site-specific, mostly older ones covering individual streets or buildings, so we check your address before designing anything that faces the road.
The River Ise runs along the east of the town, with river level stations at Barford Bridge and Slade Brook. You can check any address on the Environment Agency flood map.
