Overview

About 15 Cottesbrooke Close

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

15 Cottesbrooke Close is a three-bedroom semi-detached house in Colnbrook, Slough, Slough (SL3 0JE). It has a recorded floor area of 110 m² (around 1184 sq ft), construction records dating it to 1930-1949 and council tax band D. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The latest certificate (September 2015) shows a D (score 60), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 85), a 2-band jump. The latest certificate is from September 2015, so improvements made since then won't be reflected.

One planning record on file: an extension approved in 2001. Past consents include an extension, meaningful when judging how the property has evolved. Today's modelled estimate of £543,000 is 35.1% above the 2015 sale price. On a £-per-square-foot basis, the last sale (£340/sq ft) was about 54.7% above the typical sold price in the postcode. On the market in December 2015 and unlisted since — roughly 10 years.
