After presenting 38 Garden Design Ideas post last week, today we ran across this high altitude garden hidden between the skyscrapers in Sydney, Australia. Found on Design Rulz, this spectacular rooftop haven was designed by Secret Gardens and provides an unusual place of relaxation, far above the racket of the city. The landscaping process was focused on maximizing the vistas and creating a green oasis, 25 floors above the ground: “Buxus hedging and topiary cones add a formal element whilst iris and lavender create a whimsical effect. Timber seating frames the garden providing a place to sit and enjoy the garden and the amazing harbor views.” How would you comment on this project? Do you find this type of vantage point appealing in a city as dynamic as Sydney? Or would you rather have a similar terrace in a more secluded part of town, at a lower altitude?
