Surface now painted. sixteen storeys, comprising 56 two-storey maisonettes and 8 single storey studio flats. Plan comprises four subsidiary towers, linked to a core containing stairs, lifts and activity areas. The pattern of semi-detached maisonettes is clearly expressed in the rhythm of the elevations, in which solid balconies alternate with the narrower horizontals of the bedroom floors between.
