A total of 30 schemes from around the UK scooped awards at the Civic Trust's annual awards ceremony, held in Newcastle this year.
The winning projects were those recognised as being culturally, socially or economically beneficial, and making an outstanding contribution to the quality and appearance of the environment.
Among the winners were: the Alpine House at Royal Botanic Gardens, Kew; Wentworth Castle and Stainborough Park in Yorkshire; Hazelwood School in Glasgow; and Trinity Gardens in Newcastle.
Landscape architecture firm Southern Green designed the 2ha public Trinity Gardens and director Ros Southern said it had been an exciting landscaping scheme, which included the unexpected discovery of three native black poplars. Southern added: "It's this little green gem in the middle of the city."
Civic Trust chairman Philip Kolvin said: "We are proud the awards encompass such a wide range of schemes and allow commercial developments to compete with community projects in providing better places for people."
