Get started3 Caldecote Green is a five-bedroom semi-detached house in Upper Caldecote, Biggleswade, Biggleswade (SG18 9BX). It has a recorded floor area of 230 m² (around 2476 sq ft), construction records dating it to before 1900 and council tax band E. Other recorded features include notable views, outbuildings and attached land beyond the plot. It has already been extended once and our model flags further extension potential, a sign of buyer flexibility. The latest certificate (September 2025) shows a C (score 71).
Held since April 2004 — that's 22 years off the open market, well above the local norm. At 230 m² the property is well over the postcode median (115 m² across 5 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £828,000 sits 123.8% above the 2004 sale of £370,000. On a £-per-square-foot basis, the last sale (£149/sq ft) was about 40.2% below the postcode norm. 5 planning records sit against the property, 4 approved, 1 refused. Past consents include an extension, meaningful when judging how the property has evolved.
