Blenheim Avenue is almost entirely semi-detached houses. Homes here typically change hands around £145,000 — roughly 5% above the L21 norm. On floor area that works out near £2,680 per square metre, above the district's £1,587. Recent sales are too thin to call a trend for the street itself; L21 prices as a whole have been rising. With 16 sales across 12 homes since 2001, homes here come to market only rarely.
