Wind-powered ingenuity

The UK has some of the finest and most technologically advanced windmills in the world. Each one is unique in its design, and nearly all of them are listed buildings.

Windmills were built to turn cereal grains into flour for our daily bread. They were also adapted for other uses. The windmills of the Norfolk Broads and Cambridgeshire Fens are actually water pumps, built to drain the land so it could be used for agriculture.

A visit to a traditional working windmill is an encounter few people will forget. Although the ultimate aim is to repair a mill so it will work, this is not always desirable. Some mills are preserved through conversion to houses or other uses, and others are "mothballed" in an incomplete state. Each type comes with its own particular challenges.

Bonwick HC is the UK's leading consultancy service for windmill repair schemes, drawing on 20 years of experience. We work with highly skilled "millwright" contractors from the UK and the Netherlands.

The repair and restoration of windmills requires a unique blend of skills including those of architecture, building pathology, carpentry and joinery, metalworking, structural design and mechanical engineering. A flair for design and an eye for detail are also essential.
