“A rare offering within the historic Pentridge precinct, this former prison cell has been adapted as a private wine cellar or secure storage space, combining utility with heritage significance.
Located within the iconic D Division, originally constructed between 1887-1894, the cellar forms part of a limited collection of individually owned spaces within the restored bluestone structure. Retaining its original proportions and materiality, the space is compact, robust and atmospheric, naturally insulated by thick stone walls and supported by a climate-controlled environment designed for wine storage and preservation.
Ownership includes secure 24/7 access via swipe entry and monitored CCTV, with the flexibility to customise the internal layout for racking, shelving or private tasting use. The cellar also offers the ability to host small gatherings, with access to larger shared function spaces within the complex”
