The Kettletown Subterranean Vault & Wooded Paddock Annex
Uniting the massive 75,268 SF subterranean concrete bunker of Building 1 Lower Level (and expandable into Building 2's 105,014 SF underground vaults) with the 20-foot clear high-bay industrial structures of Buildings 6 & 7 (86,873 GSF assessor base footprint, scaling to 98,478 GSF effective preservation capacity with mezzanine decks). Collector hypercars and vintage classics reside in a 100% subterranean, windowless, climate-stabilized concrete fortress, while high-bay motorhomes, family boats, and the Lime Rock race prep shop operate from dedicated drive-in bays surrounded by the estate's mature 200-foot forest buffer.
Pillar 5: Conceptual Explorations & Industrial Adaptive Reuse
The 228-acre former IBM corporate campus affords extraordinary structural scale, engineering resilience, and landscape versatility. 242,878 square feet of the campus is completely subterranean (`FLL` Finished Lower Level across Buildings 1, 2, and 3 on municipal field cards). This massive earth-sheltered concrete bunker infrastructure provides the ultimate natural fortress for high-value vehicle preservation: constant year-round temperature stability (55°F), zero sunlight/UV paint degradation, tornado-proof reinforced concrete, and complete discretion. Simultaneously, the standalone high-bay structures of Buildings 6 & 7 (20.0-foot clear height) provide the necessary vertical clearance and drive-in garage bays for tall luxury RVs, offshore boats, and the Lime Rock motorsport prep workshop opening onto the quiet wooded campus service apron. In Southbury's August 2025 Industrial (IND) zone, these operations qualify as Special Exception adaptive reuse uses subject to P&Z site plan approval.
Proven Regional Precedent: An Established Market, Not Speculation
Climate-controlled collector-car, boat, and RV storage is already an established business in this region, not a speculative use invented for this campus. Operators such as Poppy’s Classic Car Storage, CT Car Storage, and American Metal Customs show active local demand for secure indoor storage and prep space. The Motor Vault concept simply places that proven use inside IBM’s existing lower-level garage footprints, with direct access off I-84 Exit 15, so Southbury captures commercial tax value from a service residents and collectors already seek nearby—without inventing a new market or relying on retail foot traffic.

The Subterranean Vault: 100% Underground Concrete Sanctuary
Located completely underground beneath Building 1's main lobby and executive wing, accessible via a 2,556 SF heavy commercial loading dock platform and subterranean vehicle corridors. Poured structural concrete columns and earth-sheltered perimeter walls maintain an innate year-round thermal stability (55°F) with zero solar heat gain, zero UV paint fading, and total privacy. Outfitted with hospital-grade dehumidification, NFPA 13/88A in-rack fire suppression, polished epoxy flooring, multi-tier hydraulic stackers, a glass-enclosed hydraulic scissor vehicle lift to mezzanine display decks, and an architectural steel pedestrian staircase for VIP lounge access.
The Paddock: High-Performance Race Prep & Tuning Shop
Building 6 sits on the campus service loop, sheltered behind mature Connecticut oak and hemlock trees. Commercial glass roll-up bay doors open onto a quiet, secluded paved asphalt apron (no racetrack, grandstands, or outdoor noise). Functions as an off-track race prep and alignment annex 45 minutes south of Lime Rock Park. Features 4–5 hydraulic lifts (two-post asymmetric and in-ground flush scissor lifts), Hunter computerized wheel alignment pad, an indoor sound-isolated chassis dyno room, and parts inventory.
