Practical details and location
The practical details and the map point, -8.8239, 115.1078
Safely managed drinking water, Indonesia, 2024: 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, and on the Bukit peninsula, where water arrives by truck, the question is sharper than most.
Regional data is context about the location. It does not establish conditions inside a room.
Ambient PM2.5 and PM10 near Pecatu, Bali, Indonesia, 31 days to 2026-09-06: Modelled ambient air over this location averaged 12.4 micrograms per cubic metre of PM2.5 and 17.0 of PM10 across the 744 hours to 2026-09-06, peaking at 31.5 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.
Regional data is context about the location. It does not establish conditions inside a room.
Evidence by area
All eight areas, in the order this index reads them. Every line was read and placed by a person.
Air Ecology
Every treehouse is published as air conditioned, and the Studio, Suite and Villa also carry ceiling fans. No filter grade, ventilation rate or air measurement is published.
Nobody has confirmed this one yet.
In their words: “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.”
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.
It covers the operator or the group, not this property on its own. Nobody has confirmed this one yet.
In their words: “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.”
The architects publish the Treehouse Villa's open plan as arranged for cross ventilation. No opening area, air change rate or measurement is published.
Nobody has confirmed this one yet.
In their words: “This arrangement not only ensures fluid spatial transitions but also facilitates optimal cross-ventilation, offering an ambiance that transcends boundaries between interior and exterior realms.”
Water Integrity
Rainwater harvesting, water recycling, filtration and storage tanks are published for the Uluwatu site, against a peninsula that otherwise trucks water in. No system, supplier, filter grade or panel is named, and whether this water is the drinking supply is not stated.
Nobody has confirmed this one yet.
In their words: “There are also local challenges, like water trucking in Uluwatu, Bali, which we counter with a complex rainwater harvesting and water recycling and filtration system and water tanks.”
The pre-opening account of the same system, published in December 2022, frames it as a water saving measure rather than a treatment train for what guests drink.
Nobody has confirmed this one yet.
In their words: “Grün Resort Uluwatu has implemented a sophisticated rainwater harvesting and water recycling and filtration system to reduce water usage and eliminate the need for water trucking, which is a common occurrence in the low water area of Uluwatu.”

Light Rhythm
Every treehouse is published as glazed on all sides for daylight through the canopy. Nothing is published on lighting after dark, colour temperature or flicker.
Nobody has confirmed this one yet.
In their words: “Every Grün treehouse is built on stilts and wrapped in glass, so light filters in through the canopy and the outdoors never quite leaves the room.”
The seven Treehouse Villas are published with full-height glazing on every level and white curtains for privacy and shade. Curtains are named as white, not as blackout, and no light level at the pillow is published.
Nobody has confirmed this one yet.
In their words: “Full-height, wood-framed glazing wraps each level of the villas, providing 360-degree views, while white curtains and wooden panelling provide additional privacy and sun shading where necessary.”

The property's own notice on its listing says construction outside the site may bring light into the sea view villas at night. Recorded as stray light in a sleeping zone, and not credited.
This did not meet the criterion it was recorded against.
In their words: “Please note: There is ongoing external construction nearby, outside the resort premises, which may cause occasional noise and light disturbances in the Villa with Sea View.”
EMF Harmony
Not published. We looked and found nothing on this, which is a gap in what we could read, not a finding about the building.
Materials and Textiles
The seven Treehouse Villas are published by the design press with an exposed steel frame painted green and fittings in teak, woven rattan and banana paper. Species and materials named; no emissions test, finish or paint product published.
Nobody has confirmed this one yet.
In their words: “The steel structure of the villas has been left exposed and painted in a pale shade of green, complemented by fittings in teak, woven rattan and banana paper.”

Bathroom walls in the Treehouse Villas are published as recycled plastic panels made with Ecollabo, a named supplier. No emissions data for the panels is published.
Nobody has confirmed this one yet.
In their words: “In the bathrooms, the walls have been finished using marbled panels of recycled plastic, which were developed in collaboration with Ecollabo.”

The buildings are published as reclaimed or certified wood on light steel. No certification scheme, species or supplier is named for the timber.
Nobody has confirmed this one yet.
In their words: “Grün Resort Uluwatu uses as much wood as possible in its construction. Opting for reclaimed or certified woods that act as carbon storage and reduce the total carbon footprint of the buildings.”

Food and Kitchen
A permaculture garden and mature mango and cashew trees on site are published as supplying the kitchen. No share of guest food, grower, organic status, oil or cookware is published.
Nobody has confirmed this one yet.
In their words: “Grün Resort Uluwatu’s permaculture garden provides the kitchen with fresh, healthy, local ingredients and showcases locally grown vegetables and fruits to guests. The resort also has several decade-old mango and cashew trees, which are used in the kitchen.”

Bukit, the restaurant above the cliffs, publishes a herb garden with five named plants and a hand-picked element in every dish. A garden, not a proportion.
Nobody has confirmed this one yet.
In their words: “Garden-to-glass, garden-to-plate. Every dish carries a hand-picked element that leads back here. The distance between where it grew and where you taste it is measured in steps, not miles.”
Single-use plastics are published as eliminated. What water is served, and in what, is not stated.
Nobody has confirmed this one yet.
In their words: “Instead, sustainability is embedded in every detail: from hand-shaped bamboo beams and reclaimed wood to rainwater harvesting systems, solar power, and zero single-use plastics.”

Biophilic and Healing Design
Stilt Studios, a named studio with a named lead architect, publishes the method: villas on concrete feet and steel stilts, raised to canopy level so the garden beneath is kept. A published design method for this building, not a claim of feeling.
Nobody has confirmed this one yet.
In their words: “Concrete feet and steel stilts support each of the villas, intended to lighten their impact on the site while also enhancing the "immersive" feeling of the interiors by raising them to the level of the treetops.”

The treehouses and villas are published as placed around the existing trees of a forested site kept intact.
Nobody has confirmed this one yet.
In their words: “Furthermore, the resort’s treehouse hotel and villas have been carefully placed around existing trees to create a natural environment for guests while preserving and promoting the growth of local flora.”

The Octagon, the resort's restaurant and indoor yoga space, is published with glass sliding doors, a circular skylight and openings framed on the forest.
Nobody has confirmed this one yet.
In their words: “Large glass sliding doors, a central circular skylight, and strategically positioned openings invite breathtaking views of the forest, flooding the interiors with natural light and establishing a seamless connection with the environment.”

Slatted bamboo walls, handcrafted furniture, stone paths and native gardens are published as the palette. Materials as a class; the species and makers are on the design press item above.
Nobody has confirmed this one yet.
In their words: “That story plays out in light and shadow, morning sun spilling through slatted bamboo walls, dappling handcrafted furniture, and guiding guests along winding stone paths through native gardens to infinity pools that seem to pour into the Indian Ocean.”

Sound and Sensory Ecology
The seven Treehouse Villas are published as separate freestanding buildings, so no wall is shared with another room. No isolation figure or background level is published.
Nobody has confirmed this one yet.
In their words: “Called Treehouse Villas, the project comprises seven separate guesthouses arranged side-by-side in a sloping, forested landscape, with large terraces providing expansive views out towards the Indian Ocean.”

The retreat village puts twelve units in two shared buildings on a 3 by 3 metre modular grid. No wall construction or isolation figure is published for them.
Nobody has confirmed this one yet.
In their words: “The Retreat Village complex comprises three distinct structures surrounded by lush greenery: two main buildings housing 12 units and a dedicated yoga shala.”
The property's own notice on its listing says construction outside the site may bring noise into the sea view villas. Recorded as night noise from outside, and not credited.
This did not meet the criterion it was recorded against.
In their words: “Please note: There is ongoing external construction nearby, outside the resort premises, which may cause occasional noise and light disturbances in the Villa with Sea View.”
The restaurant publishes barbecue nights with a live DJ every Friday and Sunday. A scheduled evening noise source on the site; no finishing time or level is published.
Nobody has confirmed this one yet.
In their words: “Join us for a sizzling Uluwatu BBQ and feast beneath the sky Accompanied by Live DJ Performance”
