Markland Klaschka has submitted plans for this project to build eight eco-friendly homes in the grounds of a Georgian house in Wandsworth, south London.
As well as delivering the new 'green' homes, the Marney Lodge project involves the ambitious overhaul of a historic three-storey town house, fronting the main street - a scheme which will see an extra floor added to the building and an imitation of the original roof line rebuilt on top.
Behind the revamped Georgian block, the practice proposes to build eight new two and three-bedroom houses with 'biodiversity roofs' in two separate terrace blocks.
Describing the scheme, Robert Klaschka said: 'A biodiversity roof has a deeper growing medium, roughly 100mm compared to 30-40mm for sedum, which allows a greater variety of planting. In this instance we are planning grasses and wild flowers.'
He added: 'We will also be incorporating a number of energy- and resource-saving measures in the backland development including grey-water recycling, ground-source heat and higher-than-building-regulation insulation.'by Richard Waite
