Barnsbury is Georgian squares and terraces, largely residential and largely intact. The housing is old enough that original drainage and cellar structure account for most rodent entry, and the communal garden squares give protected ground between properties. Quieter work than the rest of the borough, but the buildings are less forgiving.
