Roof gardens could spring up across the country as ministers prepare to tear up regulations and let homeowners build terraces on top of their houses.
Senior government sources said it will be easier to get planning permission to put plants, trees and furniture on roofs.
It is believed greenery above homes is good for the environment as it promotes biodiversity and helps to insulate buildings, reducing the carbon footprint.
Roof terraces, especially communal ones on blocks of flats, could improve the quality of life for people living in cities
A No 10 spokesman said: ‘It is definitely something that should be taken seriously.’
