Great Bowden is a village of greens just north east of Market Harborough, with ironstone, brick and thatched houses around its greens and lanes, and later housing on its edges. It has its own neighbourhood plan, first made in 2018.
We cover Great Bowden (LE16) and the villages around it, including Market Harborough, Little Bowden, Welham, Slawston and Foxton.
Ground, drainage and conservation in Great Bowden
Great Bowden sits on the clays and mudstones of the Welland valley, which drain slowly, with the River Welland and the Langton Brook to the south. We design for the water first.
Great Bowden has a conservation area covering the historic village and its greens, and a neighbourhood plan with policies on design and character, so road-facing changes should respect the materials around them.
Harborough's flood records note the April 1998 flood, when the Welland and the Langton Brook overtopped, affecting part of Great Bowden Lane. You can check any address on the Environment Agency flood map.
