Your next space is on the move. API Trailers designs and factory builds custom cabins under 400 sq ft on a chassis, then our own trucks deliver them and our crew sets them on site. Peaked roofs, porches, pine log or cedar siding, and cold climate construction are all options. We build matching cabins in quantity for parks, campgrounds, and RV resorts.

720 sq ft is enough room to run a whole project out of one office. The 12x60 office trailer from API Trailers gives you 12 ft x 60 ft of space with central heating and air, a 110/220 breaker panel, and steel doors with deadbolts. Add restrooms, security screens, ADA ramps, skirting, or office furniture as your site needs. A 12-wide travels as an oversize load, and API handles that transport permit in-house.

Project Spotlight: Dos Rios State Park. API Trailers designed and factory built two custom buildings for the park, a 10x18 Entrance Center where visitors check in and a 10x22 Welcome Center. Both got custom exterior and interior finishes before API delivered and set them on site. The park opened in June 2024 about 8 miles west of Modesto, where the San Joaquin and Tuolumne rivers meet.

Who says modular spaces have to look boring? This build-out proves otherwise: pool table, ping pong, foosball, and a full lounge area, all inside one of our modular units. Whether it's a break room for your crew or a rec space for your team, modular buildings flex to fit however you actually use them. See what's possible: https://apitrailers.com/modular-buildings/

Real project, real results: this modular building now serves as the training facility for the Regional Wastewater team in Santa Clara.
