Engineer Buro Happold is one three construction companies to win the Queen's Award for Enterprise this year.
The award recognises the engineering consultant's work in sustainable building.

Forticrete Roofing Products was honoured for its revolutionary double-cambered roof tile, used widely in UK housebuilding.

Leeds Environmental Design Associates also received a Queen's Award. The design firm caught the attention of the panel for its solar-heated swimming roof at a private house in Bradford.
