About 18 Cowley Close
18 Cowley Close is a three-bedroom property in Bierton, Aylesbury, Aylesbury (HP22 5DQ). It has council tax band C. The home occupies a cul-de-sac position.
Held since December 2009 — that's 16 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. One historical planning record sits against the property in 2022.
