BTG Eddisons Property Auctions will hold a live‑streamed sale on Oct 28‑29, 2026, for a Reading bungalow whose underground complex has spanned 1,300 sq ft and was built over two decades. The guide price is £300,000‑£325,000.
The labyrinth was the brainchild of civil engineer Tony Deane, who began excavating in the 1980s after a summer of bucket‑driven work. Over 20 years he and his six children dug four levels beneath the family home, carving through chalk with buckets and wheelbarrows.
Inside, the tunnels house a one‑tonne lift, a manual railway, and hidden rooms accessed through a 23‑ft rocket and a sliding concrete wall.
West Berkshire Council granted planning permission in December 2024 to add a 5,000‑sq‑ft, five‑bedroom house on the former pool site and to convert the workshop into a three‑bedroom dwelling.
Buyers eye the complex as a secure storage, data‑center, or unique retreat, and will bid during the auction; the winning offer will decide whether the underground world stays intact.
