Picket Piece, Andover

Picket Piece is a new development of over 530 houses, located in Andover, Hampshire.

This site proved an interesting challenge due to the steep topography, along with the need to provide a sustainable drainage system using permeable paving. At steep gradients permeable paving requires concrete baffles within the construction makeup to maximise the use of the void space in the sub-base stone and prevent it from collecting at the low ends of the site.

The design works included preparing Section 278 drawings for two new roundabouts and the design of the levels, drainage and makeup for new sports pitches.

We have been working with Hampshire County Council to gain adoption of the main spine road which is a bus route of porous paviour construction.
