Continuing our theme of blogs from across the pond, Urban Roof Gardens is London's only multi-disciplinary team of architects and designers that focus exclusively on roof gardens and green roofs. Their website features a portfolio with gardens from around the world including Edinburgh, Amsterdam, New York, and San Francisco. I only wish I could design my ground-level garden to look as good as these.
This is the mission of Urbanroofgardens: To raise awareness of the benefits of urban roof gardens, terraces and green roofs. To collate and publish world-class research and best-practice relating to urban roof gardens. And to offer concept to completion advice and services to both the lay and the professional citizen wishing to build urban roof gardens.
