The outer ring of dwellings number 39 or 40, with entrances to a circular street in the middle of the settlement.

A second and third field was then added to the attribute table that indicated the increase in dwelling numbers by 2004 and after 2004, respectively.

Population size (as indexed by dwelling numbers), summer heat stress, rate of collapse of lodges, and over-winter occupancy of lodges and burrows were investigated as potential determinants of dwelling selection.

It's also worth mentioning that in the course of "discussing" with some councils the LEPs submitted to formalise the residential strategies they'd agreed some years ago, DUAP is requiring dwelling numbers to be even greater than those originally agreed.
