Water world rises in Gloucestershire

CONTRACTS

LUXURY HOLIDAY homes are being built on stilts over flooded gravel pits in a Gloucestershire nature reserve using geotechnical contractor Roger Bullivant's precast concrete House Foundation system.

Set around several lakes, steel-framed homes which will sell for up to £1M are being built by Conservation Builders at the 240ha Lower Mill Estate near Somerford Keynes.

Architect Richard Reid & Associates chose Bullivant's precast system as a clean and quick method of installing the foundations. The inverted T-beams and Thermoslab floor slabs are being placed on driven precast and steel piles.

Bullivant House Foundations contracts manager Derek Murphy said the system avoided prohibitive cost or environmental impact.

'Where the houses are over water, steel piles are being driven from a temporary piling platform and cased in concrete pipe down to the lake bed to protect the steel casing and mask it from view, ' he said.

'Precast pile caps, beams and slabs are then placed to complete the foundation before the platform is removed to finish the desired effect without risk of loose material contaminating the lakes.'

For houses not founded over water, Bullivant's precast concrete compression piles are being driven at wall node points and beneath load bearing walls.
