Designed by notable architect Donald McMorran of Farquharson and McMorran.,[1] the estate comprises three rows of terraces, two blocks of flats and a community hall set around a village green.
The estate is built from traditional materials to create a village-like feel that, at the time, was considered unique for inner London.
[2] According to a council statement in 2010, the City of London Corporation built Lammas Green as a 'conscious return to the Kent vernacular, with colour-washed walls, pantile roofs and stout brick chimneys - perhaps out of step with the prevailing trends in architecture'.
Typically, McMorran differed from similar traditionalist architects at the time for his willingness to tackle progressive projects of this type.
At 57 dwellings per acre, the estate's low density was intended 'so as to establish conditions under which a community with its own continuity and life might be able to flourish'.
