Convert a Vacant Warehouse into an Indoor Padel Club

Padel is the racket sport that finally broke through in the United States. The 2026 SFIA Topline Participation Report put U.S. padel past one million players, the country crossed roughly 1,000 open courts in April 2026 - up from fewer than 50 in 2020 - and the U.S. Padel Association is projecting 10,000 courts by 2030. USPA club memberships grew more than 50 percent in 2025 alone, national operators such as Ace Padel, Padel Haus, Conquer Padel, and Proximo are rolling out multi-location footprints, and the typical new club has grown from the two or three courts of the 2022 wave to five to nine courts. The building type that makes that possible is the warehouse. Padel is played in a 20 by 10 meter glass-and-mesh enclosure with the walls in play, and the ball is routinely lobbed high, so the governing body (FIP) requires at least 6 meters (about 20 feet) of unobstructed clear height over the court and recommends 8 meters for new facilities. That rules out most retail and office space and lands squarely on clear-span industrial buildings, which is why vacant logistics boxes and flex buildings are the fastest-growing conversion category in the sport - NorthPoint Padel opened in a 32-foot-ceiling Indiana warehouse in January 2026, and Milwaukee approved a $2 million warehouse padel club the same year. The economics are real but not trivial: a court package alone runs about $30,000 to $60,000, and once the building work, lighting, HVAC, fire protection, and member amenities are allocated, an indoor conversion commonly lands between $130,000 and $250,000 or more per court. This guide walks through finding a building that actually clears, laying out courts, fixing the slab, specifying glass and lighting, and getting a change of use approved - and it is honest about where padel projects go wrong: low spots under beams and sprinkler mains, glare from lighting aimed at players looking up, and opening a club with too few courts to fill a league.

Convert a Dry Warehouse into a Refrigerated Cold Storage Facility

Cold storage is the rare industrial niche where the demand curve and the vacancy curve point at the same building. The global cold storage market sits near $41.8 billion in 2026 and is projected to reach roughly $58.5 billion by 2030 at about 8.8% annual growth, with U.S.-only estimates running higher still - around $52 billion in 2026 and forecast to roughly double by 2033 - driven by grocery e-commerce, food-waste reduction mandates, and a pharmaceutical cold chain that exploded alongside GLP-1 drugs, whose select-brand U.S. sales climbed from $7.7 billion in 2022 to $49.5 billion in 2025. Meanwhile the country is full of ordinary dry warehouses. The arbitrage is real: converting existing dry stock runs roughly $100 to $150 per square foot, against $130 to $350 per square foot for purpose-built cold storage, and the shell, the slab, the dock, and the utilities are already paid for. But the honest version of this project is that most dry warehouses are bad candidates and the building tells you which one you have in the first week. A 35-degree cooler conversion lands around $150 to $200 per square foot all-in; a minus-10-degree freezer can reach $350 to $500 once you add insulation, a heated slab, heavier steel, and industrial refrigeration. Energy alone runs $0.50 to $1.25 per square foot per month before demand charges. And as of January 1, 2026, EPA rules cap refrigerant global warming potential at 150 for cold storage warehouses holding 200 pounds of charge or more, which removes most of the easy HFC options from the table and pushes new systems toward CO2 or ammonia. This is not a build you start on speculation. Sign the tenant or the throughput contract first, then pour the floor.

Convert a Vacant Warehouse into an Indoor Bouldering and Climbing Gym

Indoor climbing has quietly become one of the most reliable second lives for an empty industrial shell. The U.S. indoor climbing wall industry is around $1.1 billion in 2026 across roughly 640 businesses, and the global climbing gym market is projected to grow from about $4.03 billion in 2026 to $8.3 billion by 2034. Bouldering-only facilities took the largest share of that market — roughly 53% — precisely because they need no ropes, no belay staff, and only 15 to 20 feet of clear height, which is exactly what a 1980s distribution warehouse already has. Be honest about the cycle, though: this is a post-boom market, not a gold rush. North America opened 53 new gyms in 2025 against 60 in 2024 with 12 closures, and 73% of operators called 2025 economically challenging even as 61% forecast a better 2026. The buildings are cheap and the demand is real, but the winners are the operators who underwrite membership density and staffing before they fall in love with a wall design.

Storage Unit to Workshop: How to Set Up a Maker Space You Can Actually Use

Renting a storage unit as a workshop costs $150 to $400 per month and gives you a dedicated space for woodworking, metalworking, or crafts without taking over your garage. Here is how to set one up.

Dry Warehouse to Cold Storage: How to Tell If Your Building Can Make the Jump

Cold storage demand is climbing while ordinary dry warehouses sit empty, and converting one costs a fraction of building new. But most dry buildings are poor candidates, and the building tells you which kind you have in the first week of diligence. Here is how to read it.

Empty Warehouse to Climbing Gym: What the 2026 Numbers Actually Support

Bouldering needs 15 to 20 feet of clear height, a strong slab, and no ropes — which describes almost every 1980s distribution warehouse in America. Here is why the building side is easy, why the operating side is not, and what a post-boom market means for anyone signing a lease in 2026.

Vacant Big-Box to Self-Storage: The Conversion That Still Pencils in 2026

Retail keeps emptying while storage demand holds, and conversions now account for close to a tenth of national self-storage inventory. Here is why the dark Kmart on the edge of town converts well, which boxes are traps, and the two line items that decide the deal.
