Union Street is a mix of detached houses and terraced houses. Sales here are sparse and mostly older — the last recorded sale was in 2004, so today's values are best judged from the wider M4 figures below. Recent sales are too thin to call a trend for the street itself; M4 prices as a whole have been easing. HM Land Registry records 2 sales across 2 homes since 1999 — homes here come up rarely.
