The Warehouse Hotel in Seattle's SODO district occupies a 1918 brick warehouse, preserving exposed timber beams and original freight elevators while adding 120 modern rooms. In Nara, Japan, the former Nara Prison—a 1908 Meiji-era facility—reopens as Hotel Nara with 48 cells converted into minimalist suites, retaining iron-barred windows. A 1920s textile mill in Lowell, Massachusetts becomes The Loom, offering 85 loft-style rooms beside restored power looms. London's Battersea Power Station adds The Power House, a 164-room property inside the iconic Art Deco turbine hall.

Finally, a 19th-century Lisbon convent transforms into Convento do Carmo, featuring 32 cloistered rooms with original azulejo tiles. Each project balances heritage constraints—seismic upgrades, landmark approvals—with contemporary amenities like rooftop bars and co-working spaces. Developers cite 20%-30% premium rates over standard new builds, driven by experiential demand.

Architects emphasize reversible interventions: steel frames inserted without damaging masonry, HVAC routed through existing chutes. The trend reflects cities incentivizing adaptive reuse through tax credits and relaxed zoning, turning liabilities into landmarks.
