Overview

About Green Diamond

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

Green Diamond is a one-bedroom semi-detached house in Brighton (BN1 1JS). It has a recorded floor area of 37 m² (around 398 sq ft) and council tax band C. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. Other recorded features include notable views and a self-contained annexe. At 37 m² this is the 8th smallest of 40 units on EPC record in Green Diamond, where floor areas span 26–185 m². The building's EPC ratings span D to B across 40 units on file. The latest certificate (February 2016) shows a C (score 72). Main heating runs on electricity: electricity, unspecified tariff. The latest certificate is from February 2016, so improvements made since then won't be reflected.

Today's modelled estimate of £303,000 is 13.4% below the 2016 sale of £350,000, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. On a £-per-square-foot basis, the last sale (£879/sq ft) was about 214.1% above the typical sold price in the postcode. 10 years since the last transfer (June 2016). At 37 m² it's 24.5% smaller than the typical home in the postcode (49 m² median across 39 EPCs).
