Property Description

Exceptionally rare opportunity to acquire a Cold War-era underground communications facility, originally constructed between 1967 and 1971 as part of AT&T’s Long Lines network and engineered for durability, redundancy, and long-term self-sufficiency. The property features an approximately 4,813-square-foot below-grade reinforced concrete bunker beneath a 987-square-foot, four-car concrete block garage. The bunker is configured with multiple secured rooms, hardened corridors, mechanical and utility areas, a generator room, decontamination room, full kitchen, and four bathrooms. An elevator connects the above-grade garage to the underground facility, while copper screening within several interior partitions provides additional electromagnetic attenuation. The facility underwent extensive renovations in the early 2000s to support its potential use as a secure data and communications center. These improvements included updates to the electrical distribution, mechanical systems, and interior spaces for sensitive equipment and long-duration operations. Power infrastructure includes commercial electric service with automatic transfer capability and a 150 kVA diesel generator supported by approximately 2,500 gallons of on-site fuel storage. Heating and cooling are provided by multiple geothermal heat pumps served by four reported geothermal wells approximately 300 feet deep. Water infrastructure includes a separate potable well reported to be approximately 125 feet deep, a 1,500-gallon fresh-water storage tank, water filtration, and an on-site septic system. The facility also incorporates multi-stage air filtration designed to support extended below-grade occupancy. Situated on approximately 9.17 private acres, the property features a high gated perimeter fence, controlled entrance, substantial setbacks, and a discreet, low-profile footprint. The property is located in Flood Zone X and is currently zoned Agricultural Preservation. The existing commercial use has been identified in the appraisal as a pre-existing grandfathered use. Potential applications include a secure private compound, data center or server facility, continuity-of-operations site, research facility, specialized storage, or other approved uses. Due to the unique and sensitive nature of the property, certain information is available only to qualified prospective purchasers. Showings by appointment only. Proof of funds required. All proposed uses, system capacities, operating conditions, zoning, and measurements should be independently verified.
