Sirius Buildings has launched Sirius Flex, a prefabricated amenity building for electric vehicle charging sites that is now available in the U.S. and Australia, with the U.S. as the company’s primary market. The modular structure adds a family restroom, snack and drink vending, sheltered seating, and 24/7 lighting and security to charging locations that often lack those features. Sirius says the building is manufactured off-site and installed as a complete, standardized unit, letting charging operators add restrooms and shelter without commissioning a custom structure for each site. The company positions Sirius Flex for highway hubs, rural charging corridors, urban sites, and future fleet and electric-trucking hubs.
Highlights
- Sirius Flex is a prefabricated building that adds a family restroom, vending, sheltered seating, and 24/7 lighting and security to EV charging sites.
- The unit is manufactured off-site and installed as a complete system, designed for repeatable rollout at highway hubs, rural corridors, urban sites, and future fleet and electric-trucking hubs.
- Sirius Flex is now available in the U.S. and Australia, with the U.S. as the company’s primary market focus.
- EVs made up roughly one in 10 new light-vehicle sales in the U.S. in 2025, according to the company, part of a broader shift toward mainstream buyers who expect charging stops to function like a normal roadside stop.
Charging Stops Are Catching Up to Mainstream Expectations
Electric vehicles have moved past the early-adopter phase into daily use for commuting, school drop-offs and family road trips, with commercial vans, fleets and heavy-duty trucking following the same shift, the company says. That brings mainstream expectations to the charging stop itself: buyers want a clean restroom and a safe place to wait, not just a working plug. Charging has gotten faster and route planning has improved, but a public fast-charging session still creates a meaningful pause in a trip. Tesla has begun rolling out a virtual queue system at select high-traffic Superchargers to manage the order drivers reach an open stall, though that addresses who charges next rather than what happens while people wait.
Charge Point Operators Are Rethinking the Site
Charging networks commonly built out their early footprint by leasing spaces from shopping centers, hotels and supermarkets — a fast way to scale without developing property outright, but one that left restrooms, food and lighting up to whichever business happened to be nearby. Sirius points to operators now developing larger, self-controlled hubs, including through direct land ownership: Tesla’s Oasis site in Lost Hills, California, runs 164 stalls around the clock; the Tesla Diner in Hollywood pairs 80 V4 Superchargers with food and a drive-in setup; and Electrify America’s San Francisco flagship includes temperature-controlled waiting areas, vending, Wi-Fi and restrooms. European operators have taken a similar approach with dedicated indoor lounges. Other U.S. operators are building toward the same model — IONNA’s “Rechargery” locations pair fast charging with food and clean restrooms, and the Pilot and GM travel-plaza network adds lounges, Wi-Fi and on-site dining to interstate corridor sites.
Company Background
Sirius Buildings was founded in Sydney, Australia, out of a modular-construction and design-systems background, and manufactures its own steel components in-house. The company describes itself as an early EV-adopter that experienced firsthand the gaps in first-generation public charging. It says the Sirius Flex format was developed from feedback gathered through meetings with charge point operators in the U.S. and Australia, combined with its own observations of charging sites.
