The most expensive streets in Mountain Ash
Mountain Ash's priciest addresses, ranked by median sold price over the last five years — from HM Land Registry records, not asking prices. Every street links to its full sale-by-sale history.
Grovers Field tops the table at a £380,000 median (top recorded sale: £410,000) — about 3.5× the £110,000 median for Mountain Ash as a whole. Priced by floor area it works out at roughly £2,276 per square metre, which separates streets that are expensive because homes are big from streets where every metre costs more. Trem Y Dyffryn and Forest View follow at £293,750 and £210,000. Each row links to the street's own page, with every recorded sale behind the figure.
Median sold price per street over the last five years, HM Land Registry Price Paid Data (standard market sales; streets with at least 5 recorded sales). £/m² is the street's median of sold price ÷ EPC floor area, shown where at least three sales match an EPC — the like-for-like measure that separates big homes from expensive ones. Street-level medians move with what happens to sell — treat them as a robust guide, not a valuation of any home.
