About Redstone Mansions

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

Redstone Mansions is a detached house in Eastbourne (BN20 7EN). It has a recorded floor area of 149 m² (around 1604 sq ft) and construction records dating it to before 1900. The latest certificate (September 2009) shows an E (score 53), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 60).

At 149 m² it's 23.1% larger than the typical home in the postcode (121 m² median across 18 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 72% of similar EPCs).

How the estimate is made
The estimate for Redstone Mansions is modelled from its 149 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in BN20 7EN. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 2 sales are recorded for Redstone Mansions. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC

The latest one for Redstone Mansions was lodged in September 2009 at band E and expired in September 2019, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
Planning records

Area figures
Crime is police-recorded street-level data over the last 12 months, which places each incident at an approximate point. The 12 schools and 30 stops listed are measured in a straight line from BN20 7EN, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
