Southdown is a street almost entirely of detached houses. The median sale price is £450,000, about 48% above the typical SN4 sale. Per square metre of floor space it comes to about £2,735, below the district's £3,286. Too few recent sales to read a street-level trend, but across SN4 prices have been easing over the last few years. HM Land Registry records 7 sales across 5 homes since 2004 — homes here come up rarely.
