Imagine sipping your morning coffee in a home that once hid Cold War torpedoes! This $10M London mansion used to be a top-secret testing site, complete with blast-proof walls and hidden tunnels. Now, it’s a light-filled, ultra-modern pad with a metallic kitchen and six ensuite bedrooms. The twist? Some of the old spy-era tunnels are still untouched—perfect for your next hide-and-seek game or a unique wine cellar. Talk about a conversation starter at your next house party! #RealEstateGoals #HomeWithAStory #LuxuryLiving #RealEstate
