Grün Ubud answers this record at reply@verifiedwellnessspaces.com. Anyone else can correct it at corrections@verifiedwellnessspaces.com.
Three wooden units in a garden behind an artist's villa in Penestanan, the painters' village on the west side of Ubud where the lanes run out into rice paddies. A treehouse suite on stilts among the trees, a studio suite with its own deck and garden, and a studio with a veranda, all with kitchenettes, a shared pool a minute's walk away and a firepit on the lawn. It is the smallest of the three Grün sites in Bali and the one the group says least about, and this record is exactly as long as what it says.
Read the rest of the description
What is published
The treehouse is air conditioned and glazed on all sides so the canopy is the view from every room. The buildings are wooden and prefabricated by Stilt Studios, the manufacturer the group's founder also runs, and the group publishes natural airflow, natural materials and solar power as its way of building. The rooms are non-smoking and the house keeps quiet hours from nine at night to six in the morning. Every one of those sits at Claimed, and each is the property's own word with nothing behind it a reader could check.
What is not
Four rows score nothing because nothing is published: what a guest drinks and how the pool is treated, how the rooms are lit after dark, anything about the wireless environment beyond free Wi-Fi, and food, since there is no kitchen but the guest's own. No species, finish, mattress, linen or toiletry is named. The rainwater and solar figures the group publishes belong to the Uluwatu site and are not credited here. The easiest lift is the simplest: one line on the drinking water, and the row moves from nothing to something.

Grün Ubud at a glance
Grün Ubud is a guest-house stay in Penestanan, Ubud, Bali, Indonesia. We read what it publishes about the eight things a building does to your biology and scored the evidence 5 of 24. Last verified 2026-09-07. Air Ecology is its best-documented pathway; nothing is published on Water Integrity.
The marker sheet
Eight building-biology pathways, each graded by the strength of its evidence. How grading works
- 0Nothing publishedNot publishedWe looked. They have published nothing about this.
- 1Their word for itClaimedThey say so, and name nothing behind it.
- 2Named and specificSpecifiedThey name the actual system, product, supplier or standard.
- 3Tested or verifiedMeasuredA published test result, a laboratory report, or an independent check: a certification body, or our own assessor on site.
Each of the 8 pathways scores 0 to 3, so 24 is the most any property can reach. Out of 24, because 8 of 8 pathways have been assessed. Unassessed pathways leave the denominator rather than counting as zero.

Out-documents 44% of the index on this pathway.
What is published, and where it came from
- Claimed
Every treehouse in the group, the Ubud suite included, is published as air conditioned. No filter grade, ventilation rate or air measurement is published.
Yes, all of our treehouses are air-conditioned. The Treehouse Studio, Treehouse Suite, and Treehouse Villa also feature ceiling fans for added comfort and convenience.
- Claimed
The group publishes its off-ground buildings as designed for natural airflow and insulation, with Stilt Studios named as the maker. A design intent, not a ventilation rate.
For this reason Grün builts with treehouses and tiny houses from Stilt Studios, that have a minimal impact on the ground, are easy to set up and have a low energy usage through innovative practices for insulation and natural air flows for the off ground structures.
- Claimed
Rooms are published as non-smoking on the property's own listing. Nothing else on combustion or fragrance is published.

Hidden behind an artist’s villa, this wooden 1-bedroom retreat with a living room and sofa evokes a cozy cabin feel—perfect for guests seeking peace, nature, and a place to relax and unwind.

Grün is seeking innovative practices to enhance nature more than impacting it by building with Treehouses and studios elevated off the ground, making use of spectacular vistas and natural cooling, while using natural building materials and operating with solar power and sustainable water cycles.

What is not published
Grün Ubud is three units behind an artist's villa in Penestanan, the smallest of the group's three Bali sites, and its own page is a room list, an amenity list and an FAQ. Nothing is published with a reading on any pathway. The treehouse is air conditioned and glazed on all sides; no filter grade, ventilation rate or air measurement is published, and the group's line on natural airflow names no rate. Nothing at all is published about drinking water, the shared pool's treatment, lighting after dark, the wireless environment beyond complimentary Wi-Fi, or food, since there is no restaurant and the rooms carry kitchenettes, so four rows score nothing. The buildings are wooden and prefabricated by Stilt Studios, the group's own manufacturer, with no species, finish, mattress, linen or toiletry named. The only acoustic facts are the property's own word quiet and a house rule of silence from nine at night to six in the morning on its listing. The group's rainwater and solar claims are made for Uluwatu and are not carried over to this site.
Regional context
Public data about the surrounding area. None of it contributes to the score, because a property cannot be marked down for the conditions outside it.
- Safely managed drinking water, Indonesia: The World Health Organization reports 30 per cent of the population nationally, 35 per cent in urban areas, 24 per cent in rural areas using a safely managed drinking water service. This describes the country, not this property, and says nothing about what reaches a guest room here. It is recorded because it is the background against which a property's own treatment is worth publishing. Source
- Ambient PM2.5 and PM10 near Penestanan, Ubud, Bali, Indonesia: Modelled ambient air over this location averaged 20.1 micrograms per cubic metre of PM2.5 and 22.9 of PM10 across the 744 hours to 2026-09-06, peaking at 72.4 PM2.5. The World Health Organization annual guideline for PM2.5 is 5. This is the outdoor air over the area, modelled rather than measured on site, and it is not a reading of the air inside any room. Source

Not published is not unsafehow to read these scores, and what this index does not promise
A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.
These scores measure disclosure. These scores describe disclosure, not property quality. This index has no commercial relationship with the properties listed unless a badge on the listing says otherwise.
Conditions change, and we will not always know. Every record is a snapshot of what a property had published when we read it, and that date is on the page. Conditions change: a property can refit, change suppliers or replace a system at any time, and nothing requires it to tell us. We re-read records and ask properties directly for updates, but there will always be a gap between what is true today and what was published when we looked. Use this as a frame of reference for what to ask, not as a substitute for asking. Take your own questions to the property before you book, and tell us if you find something we have wrong.
We report what properties publish. We do not inspect, certify or vouch for any property on this index unless a listing says we assessed it on site, and we accept no responsibility for decisions made or outcomes experienced on the basis of what you read here.
Right of reply. Anyone can correct this record at corrections@verifiedwellnessspaces.com. The property scored here answers at reply@verifiedwellnessspaces.com. Every change is logged on the changelog with the date and the reason, including when the change is ours.
Questions travelers askwater, air, EMF, and whether it is worth it
Questions travelers ask about Grün Ubud
Does Grün Ubud publish water quality testing?
No. Nothing is published, and we looked. That is a statement about the public record, not about safety.
What is the air quality like in the rooms?
We can only report what is published about the rooms themselves. Only their word for it. They say so and name nothing behind it, so it scores 1 of 3.
Is Grün Ubud low-EMF?
No measurement is published. Only 16 of the 112 properties we have researched publish any bedroom EMF information at all, so this is the industry norm, not an outlier.
Is Grün Ubud worth it?
We score evidence, not experience. On evidence, it ranks 98 of 112 researched records. The strongest documented pathways are Air Ecology and Light Rhythm; nothing is published on Water Integrity or EMF Harmony.
