North West companies Randall Thorp, Aecom, TEP and Planit IE were among the winners at this year's Landscape Institute Awards.
Manchester-based Randall Thorp won the award for landscape design over five hectares for Cambourne Green Infrastructure in South Cambridgeshire and was highly commended in the local landscape planning category for the same scheme, by Taylor Wimpey and Bovis.
Aecom won best design from one to five acres for Pier Head public realm and canal link, Liverpool.
Warrington-based landscape architect was highly commended for its work for Wirral Borough Landscape Assessment.
Planit IE was commended for its work at St John's Square in Blackpool.
Dick Longdin, partner at Randall Thorp, said: "Our work at Cambourne has been ongoing since 1989, a time when a lot of what we were doing was pioneering in terms of sustainability. It is fantastic to see our work recognised by these national awards demonstrating that volume house builders can create exemplary places to live focused on people, communities and the wider environment."
Jo Watkins, president of the Landscape Institute, said: "These awards capture the zeitgeist. In times of recession there is a need to be innovative and resourceful. Faced with a challenging economy and increasing social and environmental pressures, the benefits of careful intervention in the landscape become even more relevant and frugal innovation moves up the agenda."
