Portman Square is mostly terraced houses. Homes here typically change hands around £440,000 — roughly 39% above the DT9 norm. Per square metre of floor space it comes to about £4,815, above the district's £3,386. Recent sales are too thin to call a trend for the street itself; DT9 prices as a whole have been easing. HM Land Registry records 23 sales across 13 homes since 2013.
