Fairford Leys is a housing development[2][3] in Aylesbury, Buckinghamshire, England, designed in the urban village style, with the street and block layout making it more friendly to pedestrians and cyclists.

It has a village square hosting a number of traditionally-fronted shops, award-winning hair salon, supermarket, three restaurants, a Post Office, a family-run nursery, an ecumenical church and a community centre.

The Ernest Cook Trust, a charitable organisation that owned the land where Fairford Leys was built, was the driving force behind this project and wanted to create a model for sustainable development.

Fairford Leys has its own parish council (Coldharbour Parish), a beauty salon, primary school, GPs' practice and neighbouring pharmacy, veterinary practice, Women's Institute, ecumenical church, and a community centre (known as the Fairford Leys Centre), which hosts a wide variety of events and activities, including dance classes, badminton, karate, children's parties, wedding receptions, corporate functions and council meetings.

It was purpose-built for Fairford Leys but the education authority at the time, Buckinghamshire County Council, underestimated the number of children that would live within the catchment area.
