The sustainable tiny home trend at CES 2025 revived my dream of building a compound

Small-scale, hyper-efficient living has always appealed to me, so I was overjoyed to step into numerous examples of sustainable tiny homes this week at CES 2025. There were EV RVs, trailers geared for camping and deliverable, turn-key, self-sustaining living pods. I want one of each to create a little eco village somewhere, preferably within walking distance to a bakery, coffee shop and Thai food.

While none of these are cheap, some actually fall under what I would expect, compared to the market at large. And the suite of features employed represent some of the best sustainability capabilities available at the moment — solar power, gray water recycling, atmospheric water generation and boss-level insulation. Plus they’re all very pretty.

The camping/recreational bent of these models is great — but the fact that most wouldn’t require a permit could help address a small corner of the housing crisis, especially as more cities loosen restrictions on additional dwelling units (ADUs). One of these could easily set up in a backyard or driveway as a studio apartment for a college student, aging parent and happily single folk. I’ve got some planning to do. After CES. And a long nap.

Haus.me microhaus Pro

I’ll get this out of the way: the Haus.me Microhaus Pro was my favorite of the bunch. It’s a deliverable, ready-to-use, 120 square-foot pod that’s capable of setting up on any flat surface — grass, concrete, sand, dirt, atop cinderblocks, you name it. If it’s flat, it fits. It can suck water out of the air (and I was assured that includes low-humidity locales). It plugs into a standard extension cord, so the power can come from the grid, a solar setup or something else entirely and the integrated battery will run everything for four days without being hooked up to power.

Inside, it’s posh and lovely with every space maximized. A queen-sized Murphy bed flips up to reveal a table and two bench seats. It has a small fridge, microwave and sink in the kitchen, a full-sized shower in the bathroom, and a TV in the living space. The Pro model is fully appointed, complete with Siri Homepod voice control, fancy dishware, linens and includes the aforementioned battery. That model is geared towards Airbnbs and rentals and goes for just under $90,000. The Lite knocks thirty grand off the price as it foregoes the battery, dishes and a few other features and is intended for personal use. All models of the microhaus are available to order now.

AC Future Ai-THd

The most tony unit I saw was from AC Future. The AC Future Ai-THd is a full-sized EV RV on display at the Las Vegas convention center. This is one of three models the company will make. There’s also the Ai-THt, a trailer version and the Ai-THu which, like the microhaus, is a deliverable unit. That last one is the cheapest of the three models and the one that intrigued me the most. All three are based on the same transformable design (TH stands for transformable home) that expands three ways from 120 square feet to a 400 square-foot one bedroom apartment.

Each model will be customized to order and the available tech is impressive. Solar panels will generate 25 kWh of power daily and it also comes with atmospheric water generation to the tune of up to 15 gallons per day. There’s a full-sized fridge, a washer/dryer, dishwasher, stand-up shower and, because 2025, a whole-home AI assistant called Futura to manage things on your behalf. Pre-orders opened up at CES and AC Future plans to start production as soon as the madness of CES is behind them.

RollAway

1 / 3

I only got to peek inside the RollAway, but my colleague Jessica Conditt got to fully tour the rentable EV RV. It combines high-end hotel luxuries, from plush linens to Malin+Goetz toiletries. There’s a convertible queen-sized bed, dual-burner stovetop, shower, panoramic roof and an included projector. The RV itself has a range of more than 270 miles and a fast-charging option. Sustainability tech includes rooftop solar panels, a waterless toilet, and low-waste water systems. That should allow for some off-grid trips but the RollAway is also compatible with standard RV site hookups.

To complete the hotel-like vibes, a 24/7 concierge is on hand to help plan your trip, give you directions, make side quest suggestions and keep your space equipped on the road. RollAway just started booking trips and is nearly fully reserved for 2025. Reservations go for around $400 a night and for now is just available around San Francisco Bay, but more cities are coming soon.

Pebble Flow

1 / 5

My colleague Sam Rutherford saw the prototype Pebble Flow EV trailer at last year’s CES (and his pictures are always much better than mine). I checked out the production model the company brought to the show this year. The differences are slight but meaningful. Basically, Pebble asked prospective customers to tour the prototype and tell them what they should change. One directive was “more windows” so a skylight was added, along with a larger window at the back. The cupboards are now easier to access. And the overall shape is now more aerodynamic, which should make pulling the trailer easier even easier.

Being easy to pull was already one of the Flow’s selling points. The 24-foot trailer can be outfit (for a price upgrade) with a dual-motor drivetrain that helps propel itself to reduce drag on the towing vehicle. That upgrade also includes a remote control option that lets you park and hitch the trailer via the app. Again, there’s a Murphy queen bed that becomes a workspace and the dinette table folds down to accomodate two more sleepers. There’s a full kitchen, a shower/bath stall with glass doors that change from opaque to clear with a button push. There’s a 45 kWh battery and 1.1 kW solar array. It starts at $109,500 and bumps up to $135,500 with the motor upgrade. The first deliveries should be available in spring of this year.

Lightship AE.1 Cosmos

1 / 4

Fun fact: Lightship is the only not-exclusively California company on this list. The California and Colorado-based company makes the AE.1 Cosmos, another solar-powered all-electric trailer that also with a motor-assist feature. In addition to the motor, the Cosmos also collapses down by four feet when it’s in “road mode” to reduce drag. Inside there’s a full kitchen with dishwasher, refrigerator, microwave, convection oven and induction cooktop. Two sleeping areas accommodate up to four and both convert to living areas (a dinette and a daybed/couch). Everything is powered by a 1.8 kWh solar array and battery banks.

Lightship had the Cosmos set up in the lot just outside the convention center. The space was decked out with a pebble gravel floor complete with scrubby desert plants and a starry night backdrop that blocked out the convention center itself. If I squinted, I could pretend I was out in the desert somewhere, with everything I needed just over there. It was a bit of a downer to leave it and return to the chaos that is CES. But now the sad bit: Only 50 will be produced. Each one will be manufactured in the company’s Broomfield, Colorado facility and will sell for $250,000 each, with units shipping this summer.
