It has a recorded floor area of 50 m² (around 538 sq ft), construction records dating it to before 1900 and council tax band A. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs.

The latest certificate (July 2009) shows an E (score 53), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 58). Main heating runs on electricity. The latest certificate is from July 2009, so improvements made since then won't be reflected.

It hasn't traded since November 1999, a hold of 27 years that's notably long for the area.
