Roof top gardens are more than just a marketing gimmick, they are an increasingly important part of urban landscape as investors and residents look for a cool oasis in urban heat islands.
According to Domain, green spaces on rooftops and podium levels are being highly sought after by purchasers. Developers of modern terrace developments are including a ‘village green’ for the use of residents.
The City of Sydney has a green roofs and walls policy, designed to improve the city’s sustainability and it is likely that such innovations will become national standards over the next decade.
According to the Fifth Estate, urban greening can reduce surrounding temperatures by up to six degrees-C while roof and wall gardens can reduce reliance on air-conditioning for cooling as well as providing visual amenity and habitats for inner city wildlife – like bees, with buildings such as Brisbane’s The Green giving approval for an apiary.
Melbourne City Rooftop Honey is bringing hives into the city and encouraging urban plantings such as roof top gardens to provide pollen and nectar.
The honey and wax from hives is collected and then sold locally in the form regional honeys (including north Yarra, south Yarra and Melbourne CBD) and beeswax products such as candles and lip balms.
Also in the city, a 2000-square metre elevated park will be the centrepiece of a $1.9 billion development linking Melbourne’s CBD with Docklands.
The ‘park in the sky’ will span parts of Wurundjeri Way and Collins Street as well as be home to seven commercial and apartment buildings. Although the development is a 10 year project, the elevated gardens are scheduled to be complete by 2018.
In addition to providing physical and visual amenity, roof top gardens also provide important storm water mitigation by minimising surface run off. Water is absorbed by the soil and the remaining stormwater that filters through to the roof layer, is channelled to storage tanks for watering plants, making roof top gardens largely self sufficient.
