The apartment building, in London, designed by Kenneth Frampton, in 1960, is composed of 48 maisonettes - 36 two-bed units and 12 one-beds. The ordering system comprises stacked pairs of units that cross over and beneath each other linked mid-floor by adjacent stairs and baths. The planning is rigorously efficient, netting approximately 240 DUA. A skip-stop circulation system means only five corridors are needed to serve eight residential levels. And the stacking configuration makes for logical construction. As with the Immeuble Villas, the units are of good spatial quality. All are dual aspect, and oriented so all the living spaces face the street and sunset views and all the bedrooms overlook a shared garden.
