Remote work has reshaped how people think about office space, and Sol Tiny’s latest build takes that rethinking to its logical extreme. The Off-Grid Luxury Mobile Double Office is a trailer-based unit that packs two fully independent workspaces and a sleeping area into a 26-ft (7.9-m) frame, all while running entirely on solar power.
Built on a double-axle trailer, the unit spans 10 ft (3 m) wide, broader than a standard tow, which means it requires a permit for road transport. The wheels have been removed in the current listing photos, but can be reattached for relocation. On the outside, the office is clad in cedar with a standing seam metal roof, giving it a clean, modern appearance that wouldn’t look out of place next to a residential property.

Inside, the layout is split into two distinct rooms, both finished in board-and-batten paneling with generous glazing and skylights that keep the interiors bright. The larger of the two workspaces is accessed through a single door and includes a desk, bookshelves, a small wood-burning stove, and a mini-split air-conditioning system. It also features a queen-sized Murphy bed that folds down from the wall, making it possible to stay overnight after a long work session without heading back to the main house.
The smaller workspace, entered through double glass doors, mirrors much of the same setup with its own desk, bookshelves, stove, and climate control. It trades the sleeping option for a more compact footprint, and there’s even room for an optional treadmill for those who like to move while they work. Neither space includes a bathroom, so the unit is best suited for use alongside an existing home or building with access to those facilities.
Power comes from eight 420-W solar panels mounted on the roof, backed by a battery system that keeps things running off-grid. There’s also the option to plug into the electrical grid when needed. For connectivity, a Starlink system handles high-speed internet, which makes the office functional in remote locations where traditional broadband isn’t available.
The Off-Grid Luxury Mobile Double Office is currently listed for sale at $98,000, not including delivery, and is located in Nevada City, California. For anyone looking to add a dedicated work setup to their property without the commitment of a permanent structure, Sol Tiny’s dual-office concept offers a flexible alternative that can, quite literally, be moved whenever plans change.
