About Theobalds
Theobalds is a detached house in Blackheath, Guildford, Guildford (GU4 8RB). It has a recorded floor area of 309 m² (around 3326 sq ft), construction records dating it to before 1900 and council tax band H. The latest certificate (March 2015) shows an E (score 54), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 74), a 2-band jump. The latest certificate is from March 2015, so improvements made since then won't be reflected.
Held since October 1996 — that's 30 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 309 m² the property is well over the postcode median (118 m² across 15 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs). Today's modelled estimate of £2,203,000 sits 487.5% above the 1996 sale of £375,000. On a £-per-square-foot basis, the last sale (£113/sq ft) was about 75.3% below the postcode norm. 6 planning records sit against the property, 2 approved, 2 refused. Past consents include an extension, a porch and partial demolition, meaningful when judging how the property has evolved.
