Following criticism from CABE, the practice decided to lose the retro-style modular pods in the original 30-storey proposals and instead create a higher but 'more elegant' tower (above).
This resulted in the ditching of the 'showy, active energy-generation technologies' in favour 'of discrete passive measures to reduce the carbon footprint of the development'.
Drawn up for developer Time and Tide, the Gravity development will sit at Manchester city centre's eastern gateway and will create 383 apartments, topped by three duplex penthouses.
A spokesman for the practice said: 'We have welcomed CABE's involvement in a challenging scheme.
'Sustainability is now at the heart of the scheme and elements such as the commercial street frontages and garden area have been enhanced.'
