Part of the multi-million pound regeneration of south Kilburn, the scheme will create 130 new affordable flats and maisonettes in Granville Road.
The practice saw off competition from PRP, Shepheard Epstein Hunter, HTA and John Thompson to land the project which will be split over two phases and is to include a new home for the Tabot Centre - a local community youth facility.
The scheme will boast a range of sustainable features, including sedum-planted roofs, solar thermal panels and rainwater harvesting.
Describing the development, a spokesman for the practice said: 'The urban design is a contemporary reinterpretation of the historic London terrace, forming a dialogue with the existing Victorian street pattern; respecting building line and adjacent height.
'[In addition] the roof-life concept seeks to deliver substantial external space for each dwelling, providing patios, terraces and balconies.'
Work is due to start in May this year and the building is scheduled for completion in autumn 2007.
