Due for completion in autumn of 2010 the much anticipated Landmark development in London's Canary Wharf has announced it's going to be greener or perhaps more literally, browner.
It consists of two sleek towers at 22 Marsh Wall, the tallest of which will be 140 metres, designed by Squire and Partners that have been sold with success by the Young Group to occupiers and investors alike.
The revised plans will now see the roofs of the buildings made brown, something that is similar to a green roof but focuses more on the natural habitat of the area than a cultivated garden. This will be used to attract wildlife like Black Redstarts and other flying things that are known to inhabit the area.
The newly planned brown roofs will be made from sedum mat and planted with a variety of wild flowers and rockery plants. Near the edges hardier plants to help absorb the forces of the stronger wind whilst the central areas will be covered in grasses and flowers. A mixture of reclaimed timber and substrate will also be used to create nesting areas on the roofs.
Other eco-innovations in the tower include a biomass boiler that will reduce the need for using fossil fuels by burning wood chip, pellets or cereals instead.
There is also a combined heat and power plant to provide the residences and the sites commercial properties with heat and hot water reducing the schemes co2 output.
With the brown roof, the project points the way for other buildings in the area that could do the same but have so far failed to do so. Most of Canary Wharf and its surrounding towers simply have not utilised the idea of nature parks in the sky.
