A closer look at Grün Ubud

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.

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.

Wellness Score 3.0, last changed 7 Sept 2026 when the newest evidence was read. It moves only when evidence does. How the score is made

Publishing something is not the same as it being good. Every line below was read and placed by a person, not scored by a machine. What each rung means

Verified in person means a Human Garage Certified Spaces assessor saw it on site. Named means the property published something you can look up: a brand, a product or a number. Stated means it says so with nothing behind it. Not published means we looked and found nothing, which is a gap in our reading and not an answer about the building.

The evidence, area by area

Sources for this page

Air3 notes

  • 3 stated

The air in a closed room is what you breathe for eight hours. What decides it is the filter grade, the fresh air rate, and whether damp has ever been looked for.

  • Air conditioning, filter unstated

    On their website

    Every treehouse in the group, the Ubud suite included, is published as air conditioned. No filter grade, ventilation rate or air measurement is published.

    Source

  • Designed for natural airflow

    On their website

    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.

    Source

  • Non-smoking rooms

    Published by Booking.com, property listing

    Rooms are published as non-smoking on the property's own listing. Nothing else on combustion or fragrance is published.

    Source
What to ask them
  • What filter grade is fitted to guest room air handling, for example MERV 13 or HEPA H13?
  • What is the fresh air supply rate per person in a guest room?
  • Are carbon dioxide, particulate or volatile organic compound levels measured, and are the readings published?
  • Is there a mould inspection and remediation protocol, and when was it last run?
  • Are there gas cooktops, fireplaces or other combustion sources inside guest rooms?

Light & sleep1 note

  • 1 stated

Light is what tells a body the time of day. The part a building controls is what its fittings emit and when, which a named product or a colour temperature makes checkable.

  • Glazed on all sides

    On their websiteTreehouse

    The treehouse is published as glazed on all sides for daylight through the canopy. Nothing is published on lighting after dark, blackout, colour temperature or flicker.

    Source
What to ask them
  • Is guest room lighting tunable or circadian, and what specification is published?
  • What colour temperatures are used in the evening, and are fixtures flicker free?
  • Do sleeping areas have full blackout, and is it specified?
  • What daylight access does a typical room have?
  • Is exterior lighting shielded or reduced overnight?

Materials2 notes

  • 2 stated

The things you sleep on and touch: the mattress, the sheets, the pillows, and the paints, glues and finishes around them. A named fabric, a fibre content or a certification can be looked up. A structural palette tells you about the building, not about the bed.

  • Wooden suite, species unstated

    On their websiteTreehouse suite

    The treehouse suite is published as a wooden one-bedroom building behind an artist's villa. Wood as a class; no species, finish or supplier named for this site.

    Source

  • Stilt Studios prefab builder

    On their website

    The group names Stilt Studios, a prefab manufacturer under the same founder, as the builder of its units, and natural materials as the palette. No material is named beyond wood.

    Source
What to ask them
  • What are the mattresses made of, and are they treated with flame retardants?
  • What is the fibre content of the linen, and is it certified, for example to GOTS or OEKO TEX?
  • Which paints, adhesives and sealants were specified, and are they low emission?
  • What cleaning and laundry products are used, and is the list published?
  • Are there named low emission certifications on the flooring or joinery?

Nature2 notes

  • 2 stated

Daylight, planting, outlook and the way a room meets the outside are what make a place feel the way it does. Named design decisions can be checked; atmosphere cannot.

  • Forested garden setting

    On their website

    The treehouse suite and the wooden studios are published as set in a forested garden, the treehouse among the branches.

    Source

  • Deck and own garden

    On their websiteStudio suite

    The studio suite is published with an outdoor deck and its own garden, the studio with garden views from a veranda.

    Source
What to ask them
  • Does every guest room have direct outdoor access or an operable opening?
  • What is the published design intent behind the natural materials used?
  • What are the typical ceiling heights and room volumes?
  • Was the landscape designed with native planting, and is the palette published?

Quiet2 notes

  • 2 stated

What you can hear at three in the morning decides whether you slept. Insulation, plant and machinery, and what sits next door are what decide it.

  • No noise level published

    On their website

    The property publishes its surroundings as quiet. No background level, separation or plant noise figure is published.

    Source

  • Quiet hours stated

    Published by Booking.com, property listing

    A house rule of quiet from nine at night to six in the morning is published on the property's own listing. A rule for guests, not a measurement of the site.

    Source
What to ask them
  • What is the measured background noise level in a guest room at night?
  • What acoustic separation is specified between adjoining keys?
  • How loud is the guest room air conditioning at its lowest setting?
  • Is fragrance diffused into guest rooms or public areas, and can it be declined?

WaterNot published

You drink it, cook with it and stand under it. What is in it depends on the source and on what, if anything, filters it, and both are things a property can name.

We found nothing published on this. That is a gap in what we could read, not a finding about the building.

What to ask them
  • What is the water source, and what treatment is applied before it reaches a guest room?
  • Is there a published contaminant test panel, and which laboratory ran it?
  • Is shower and bath water filtered, and to what specification?
  • How are pools and spas sanitised, and is the chemistry published?
  • How is drinking water delivered, and is it treated on site?

Wireless & wiringNot published

Wiring, routers and devices put electromagnetic fields in a room. What a building decides is where they sit relative to the bed, and whether anyone has measured it.

We found nothing published on this. That is a gap in what we could read, not a finding about the building.

What to ask them
  • Are guest rooms wired for data, or is access wireless only?
  • Where are wireless access points and smart meters placed relative to the bed?
  • Have field levels been measured in sleeping areas, and by whom?
  • Can a guest have wireless disabled in their room on request?
  • Is any shielded cabling or shielding material specified in the build?

FoodNot published

What a kitchen cooks with and where it buys are the parts of a stay you take inside you. A named oil, a named supplier or a published share is checkable; “healthy” is not.

We found nothing published on this. That is a gap in what we could read, not a finding about the building.

What to ask them
  • What share of produce is grown on site or sourced locally, and is it verified?
  • Which cooking oils are used, and is the policy published?
  • What cookware is used in the kitchen?
  • Is kitchen and ice water filtered, and to what specification?
  • Is there a published position on additives, preservatives or allergens?

Not everything is published, and an empty row is a gap in what we could read rather than a fault in the building. If one of these matters to you, ask the property before you book. Send us something that updates this record

Compare what each stay offers, how it was checked and what still needs confirming. Assessment labels describe the review, not an overall quality rating.

An unconfirmed pathway means we have not found evidence yet. It does not mean the property is unsafe, unhealthy or poorly run.

A Wellness Score rates what a stay has demonstrated: what it publishes, what it confirmed with us and, on a Certified stay, what Human Garage Certified Spaces assessed. Pathways we know nothing about are left out, and the Evidence label beside every score says how much is known. Listings are free.
