About 21 Grafton Street
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
21 Grafton Street is a four-bedroom mid-terrace house in Cambridge (CB1 1DS). It has a recorded floor area of 99 m² (around 1066 sq ft), construction records dating it to before 1900 and council tax band E. The latest certificate (February 2014) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 79). The latest certificate is from February 2014, so improvements made since then won't be reflected. Period features are noted in the property record.
Most recent transfer: December 2021 at £685,000. Across the public record there are 4 sales, relatively high churn for a single property. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One planning record on file: an extension approved in 2010. Past consents include an extension, meaningful when judging how the property has evolved. At 99 m² it's 24.5% larger than the typical home in the postcode (80 m² median across 33 EPCs). 4 bedrooms is on the larger side for this postcode, where 2 is the typical count. Across 1998–2021, sale prices on this property compounded at 7.3% per year. Today's modelled estimate of £811,000 is 18.4% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£643/sq ft) was about 59.1% above the typical sold price in the postcode.

Start your researchHow to read this page
Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 21 Grafton Street is modelled from its 99 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in CB1 1DS. 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. 4 sales are recorded for 21 Grafton Street. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
- Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 21 Grafton Street was lodged in February 2014 at band D and expired in February 2024, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. 1 application is matched to 21 Grafton Street. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
- Crime is police-recorded street-level data over the last 17 months, which places each incident at an approximate point. The 27 schools and 3 stops listed are measured in a straight line from CB1 1DS, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 21 Grafton Street is in council tax band E. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
