Convert a Warehouse into Indoor RV and Boat Storage

Convert a Small-Bay Industrial Unit into a Community Makerspace

Small-bay industrial space is the tightest part of the industrial market in 2026. While warehouse vacancy overall has climbed into the 7 to 8 percent range, buildings under 50,000 square feet are sitting near 4 percent vacancy by most broker counts, and only about 7 percent of new industrial construction is that small. The people competing for those bays are local: contractors, fabricators, small manufacturers, and the hobbyists, artists, and side-business owners who have outgrown a garage but cannot afford a shop of their own. A membership makerspace serves that last group by splitting one well-equipped bay among dozens or hundreds of members. It is also a business that fails in predictable ways, so this guide is honest about them. Spaces close when rent outruns membership, when the woodshop draws a fire marshal's complaint about dust, or when pricing is set too high for the members who actually show up. Open Works in Baltimore cut its all-shops membership from $125 to $80 a month after its own data showed the fewest members sat at the top price point. The conversion itself is not structurally complicated, which is why it rates intermediate rather than expert: no new floors, no change in building height, usually no new plumbing beyond a utility sink. What decides success is three things you check before signing the lease: whether the electrical service can run a cabinet saw, a dust collector, a welder, and a compressor at the same time; whether the woodshop pushes the space into a Factory (F-1) occupancy and, past 2,500 square feet of dust-producing woodworking, into a sprinkler requirement; and whether the landlord will allow welding, lasers, and noise after 6 p.m. This guide walks through those checks, the layout, dust collection, the build-out, safety systems, and the membership model, in the order you should tackle them.

Convert a Warehouse into an Edge Data Center

Data centers have become the most supply-starved property type in America. CBRE's H1 2026 North America report put primary-market vacancy at a record low of 1.4 percent, with more than 80 percent of the capacity under construction already preleased and less than 1,500 MW of future supply left on the table - roughly six months of demand at the current absorption pace. Hyperscalers are chasing hundred-megawatt campuses, but AI inference, private cloud, healthcare imaging, media rendering, and latency-sensitive enterprise workloads are pushing demand down to the 1 to 5 MW edge facility that sits close to users, and that is exactly the size an existing warehouse can hold. For most of the last decade developers razed old buildings and built new, but with land, entitlements, and equipment lead times all stretched, adaptive reuse is back in the playbook: industry cost studies put a warehouse-to-edge conversion at roughly $7 million to $10 million per megawatt of IT load, about 10 to 15 percent below greenfield and six to twelve months faster, and Prologis has been converting its own warehouses into powered shells for years. The building is the easy part, though. The single fact that decides whether this project exists is power: a site with a utility that can deliver several megawatts within a year or two is a data center opportunity, and an otherwise perfect warehouse without that commitment is just a warehouse. After power come the slab, which must carry racks that weigh 2,000 to 3,500 pounds each; the roof, which may need to support chillers or dry coolers at many times typical warehouse loads; clear height of 14 feet or more for air or liquid-cooling distribution; diverse fiber routes; and a zoning board that is increasingly wary of generator noise and grid strain. This guide walks through securing power first, vetting the shell, choosing a cooling strategy that survives the jump to high-density AI racks, ordering long-lead electrical gear, permitting the generators, and commissioning a facility that tenants will actually lease.

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 an eight-court padel club in a light-industrial building 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.

Flex Bay to Makerspace: What Keeps a Community Shop Open in 2026

A small industrial bay can become a shared woodshop, metal shop, and laser room for dozens of members. The build is manageable. Rent, power, and pricing are what close these spaces, so here is what to check first.

Warehouse to Padel Club: Why 2026's Breakout Racket Sport Needs an Industrial Building

Padel passed one million U.S. players and 1,000 courts in 2026, and nearly every new club needs the same thing: a warehouse tall enough to lob in. Here is what makes a building work.

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.
