Dome ADU on Airbnb: Which ADU Type Earns the Most?

When investors try to define Airbnb success with an auxiliary dwelling unit (ADU), the question is never just "which structure looks coolest" — it's which structure delivers the best return on every dollar invested.

James Svetec, co-author of Airbnb Unlocked and founder of BNB Mastery, ran a head-to-head comparison of five ADU types — A-frames, geodesic domes, treehouses, yurts, and RVs — using real AirDNA revenue data from the Asheville, North Carolina market to find out exactly which ones perform best as short-term rentals.

What Is an ADU on Airbnb?

An auxiliary dwelling unit (ADU) is a secondary structure built on a property — typically on land with acreage — that functions as a rentable short-term accommodation. On Airbnb, ADUs have exploded in popularity as a way for property owners to generate additional cash flow without building a full second home.

The ADU strategy works like this: buy a property with significant land, then construct one or more smaller, unique structures — yurts, domes, A-frames, treehouses — and list them on Airbnb as standalone experiences. Each structure generates its own revenue stream independently.

This is also the backbone of the glamping retreat model, where a single property hosts multiple ADU types, each offering guests a different experience. BNB Mastery's own team is currently developing a 100-acre glamping site north of Toronto using exactly this strategy — and the data from projects like this shaped the analysis below.

For a broader look at what makes STR investing work, three things every Airbnb investor needs to know is a solid starting point before committing to any ADU type.

Why Asheville, NC Is the Perfect Testing Ground

Finding apples-to-apples comparisons across ADU types is harder than it sounds. Geography alone can swing revenue by 30–50%, so isolating variables requires looking at a single, data-rich market.

Asheville and the surrounding North Carolina region turned out to be an ideal testing ground. The area has a dense concentration of unique short-term rental properties — yurts, geodesic domes, treehouses, A-frames — all operating in the same tourist market. That makes it possible to compare revenue figures with a reasonable level of confidence that location isn't distorting the results.

Revenue data was pulled from AirDNA, a platform that tracks actual Airbnb earnings at the property level. Using their market minder tool, James was able to see exactly how much each comparable property earned over the prior 12 months, including occupancy rate, availability, and average daily rate.

A-Frame Cabins: High Cost, High Reward

The A-frame in this comparison is a small, well-finished cabin in the woods outside Asheville. It's not a massive house — just a cozy, properly designed structure with a loft, a beautiful back deck, and strong views. Clean, photogenic, and well-positioned for the Airbnb market.

The numbers tell the story clearly:

• Days available: 356 out of 365
• Occupancy rate: 96%
• Annual revenue: $95,000

That is exceptional performance by any standard. A well-built A-frame in the right market can realistically generate $80,000–$100,000 per year, which puts it in a category that most residential real estate investments simply cannot match.

The trade-off is cost. A-frames are real structures — they require a foundation, proper construction, and significant materials. Depending on size and finish level, you're typically looking at $150,000–$400,000+ to build one properly. The upside is that A-frames carry actual equity. Unlike temporary structures, an A-frame can be sold as a standalone property, offering both cash flow and long-term appreciation.

Pro tip: Guest capacity matters significantly here. If you can build an A-frame that sleeps four rather than two, expect a meaningful jump in average daily rate and total revenue. The Asheville A-frame in this comparison accommodated more guests than the dome, treehouse, or yurt — which almost certainly contributed to its revenue lead.

Geodesic Domes: Best Cash Flow per Dollar

The geodesic dome is where things get genuinely interesting for investors focused on cash flow efficiency. The dome analyzed here is located in Alexander, North Carolina — a short drive north of Asheville — and features dramatic transparent panels at the front, panoramic views, and a thoughtfully finished interior including an outdoor shower.

Revenue data for this dome:

• Days available: 225 out of 365
• Occupancy rate: High (property was frequently booked when available)
• Annual revenue: $33,000 (available only 225 days — extrapolated to $40,000–$50,000 if listed year-round)

Now look at the cost side. A geodesic dome structure — just the shell with everything needed — runs approximately $8,000 to $25,000. Add in the interior finishings, the platform or foundation, and amenities like an outdoor shower, and total setup cost lands around $30,000–$40,000 for a finished, guest-ready unit.

If that dome earns $40,000–$50,000 per year, the cash-on-cash return is extraordinary. Few real estate investments — of any type — deliver that ratio.

Geodesic domes also benefit from a powerful uniqueness factor. Guests actively seek out unusual experiences, and staying in a dome with panoramic forest views is something most people cannot get anywhere else. That novelty drives bookings and allows hosts to charge premium nightly rates.

For the full breakdown on adding a dome to a property, the detailed guide on adding a geodesic dome ADU to Airbnb covers the process and costs in depth.

The one limitation: domes are temporary structures. There is limited equity to extract if you eventually want to sell the property. You may be able to sell to another STR investor based on cash flow, but that market is narrower than traditional real estate.

If building equity is a priority, the A-frame wins. If maximizing cash flow return on capital is the goal, the dome may be the strongest option in this comparison.

Treehouses: Unique Experiences That Guests Love

Treehouses are one of Airbnb's most consistently strong-performing unique property types, and the data here backs that up. The treehouse analyzed in this comparison was available for 233 days and generated $38,000 in revenue — outperforming the RV and yurt despite being available fewer days than either.

The "cool factor" of a treehouse is hard to overstate. It's a fundamentally different experience from a hotel room, a cabin, or even a dome — there's an emotional appeal to being elevated in the trees that guests respond to with enthusiasm. That translates into strong reviews, repeat interest, and word-of-mouth marketing that costs the host nothing.

On the cost side, treehouses vary widely depending on complexity. The one in this comparison appears to have been built primarily with raw materials from the land itself — a resourceful approach that significantly reduces upfront investment. A professionally built treehouse with similar features would likely run $20,000–$40,000 on the low end, though elaborate designs can cost considerably more.

Important safety note: Treehouses involve elevation, which means structural integrity and guest safety must be prioritized. Proper construction, regular maintenance inspections, and appropriate liability coverage are non-negotiable.

RVs: Why Convenience Isn't Enough

The RV is included in this comparison because it's the first thing many property owners think of when they want to add an income-generating unit to their land quickly. Park an RV, furnish it, list it. Simple. Fast. Low barrier to entry.

Unfortunately, the data is unambiguous: RVs underperform dramatically compared to every other structure type in this comparison.

The RV analyzed here was actually a nicer unit — well-maintained, properly set up — and it was available for more days than the treehouse or dome. Here's what it produced:

• Days available: More than 233
• Occupancy rate: 81%
• Annual revenue: $19,000

That's roughly half the revenue of the treehouse, which was available fewer nights. Why? Average daily rate. Guests simply are not willing to pay much for an RV experience. RVs read as cramped, temporary, and uninspiring. They lack the "experience" quality that drives premium pricing on Airbnb.

A treehouse is an adventure. A dome is a conversation piece. An RV is... a thing most people have seen before and don't find particularly exciting.

This doesn't mean RVs can never work as short-term rentals — context matters, and some very well-designed RV parks with strong amenities do perform well. But as a standalone ADU parked on land, an RV is the weakest option in this group by a significant margin.

Yurts: Solid Middle-Ground Option

The yurt rounds out the comparison as a genuinely interesting middle-ground option. Yurts have an authentic, rustic appeal — round, fabric-walled structures with a distinctive interior feel — and they are genuinely unique experiences that guests seek out.

The yurt analyzed here was available all 365 days of the year and generated $38,000 in annual revenue. That puts it on par with the treehouse in raw dollar terms — but the treehouse was only available 233 days. Adjusted for availability, the treehouse and dome both outperform the yurt on a per-available-night basis.

Setup costs for a yurt are comparable to a geodesic dome — probably in the $30,000–$50,000 range for a finished, guest-ready unit with proper amenities. That's a reasonable investment for $38,000 in annual revenue, though the dome's higher revenue ceiling (when extrapolated to year-round availability) gives it an edge on cash flow efficiency.

Yurts are still a worthwhile ADU option, especially for hosts who want to diversify their glamping property with multiple structure types. Mixing a dome, a yurt, and a treehouse on the same land creates a multi-unit property with different experience options — which broadens guest appeal and stabilizes income across booking cycles.

What Actually Drives ADU Performance on Airbnb

Across all five structure types, one pattern emerges clearly: uniqueness is the primary driver of short-term rental performance, not square footage, not the number of beds, and not the amenities list.

So what does this actually look like in practice? Here's how to think about it:

• Novelty premium: Guests pay significantly more per night for an experience they cannot replicate at home. Domes, treehouses, and A-frames all benefit from this. RVs do not.
• Guest capacity: Accommodating four guests instead of two can materially increase average daily rate. All else equal, a larger yurt or dome that sleeps four will outperform a two-guest version of the same structure.
• Photography and listing quality: Unique structures are inherently photogenic, but they still need great photos to convert views into bookings. Strong listing presentation amplifies the inherent appeal of the structure.
• Year-round availability: Several of the properties in this comparison were only available for 225–233 days. Hosts who optimize their calendar and pricing for shoulder seasons can significantly increase total annual revenue without changing anything about the property itself.

For pricing strategy that extracts maximum revenue from any ADU type, these three Airbnb pricing hacks are worth reviewing before setting your rates.

Connecting with other experienced STR investors who are actively building glamping properties and ADU portfolios can also accelerate decision-making significantly. The BNB Tribe community is a strong resource for hosts who want real-world feedback on ADU strategies, pricing, and operations from people doing this at scale in 2026.

Which ADU Should You Build?

The answer depends on what you're optimizing for. If you want to define Airbnb success purely by cash flow per dollar invested, the geodesic dome is hard to beat — low setup cost, strong revenue, and a uniqueness factor that keeps bookings coming.

If building real property equity matters alongside cash flow, an A-frame is the stronger long-term play despite the higher upfront cost.

Treehouses offer a compelling middle ground — lower cost than an A-frame, strong uniqueness, and revenue that outpaces yurts and RVs on a per-available-night basis. Yurts are a solid addition to a multi-unit glamping property but probably not the standout choice if you're building only one structure.

And RVs, while easy to set up, simply don't generate the revenue that makes the math work compared to any purpose-built unique structure.

Whatever direction you choose, the data is consistent: build something unusual, photograph it well, price it strategically, and make it available year-round. That combination outperforms a generic accommodation every time — regardless of structure type.
