Demand for sustainable luxury climbs every year.
Will your property capture it, or watch it go next door?
We’re a Bali-based sustainable design and engineering consultancy for hospitality in Indonesia and beyond. We work out how your building should use energy, water, materials and land, then sit alongside your architects and engineer those decisions into the design, from the first concept sketches to the day it opens.
In practice that means how the building stays cool with far less air conditioning. Where rain goes when it lands on your roofs: into tanks and gardens, or down a drain and gone. What happens to wastewater and kitchen scraps: treated, composted and returned to the landscape, or trucked to a landfill every morning. And how much of the original site survives the build: the mature trees, the slopes, the streams your guests are coming to see.
We design for performance and payback
The targets we commit to from the first design decision, and the payback that follows. (Targets may vary by project type and site conditions.)
Sustainability your guests can feel
Sustainability reaches most hotel guests as a laminated card about reusing towels. When it's engineered in from the first sketch, it reaches them as comfort they can feel and can't quite name. They'll call it the vibe in their review. It's engineering.
The Loop House | Bali
Cool at 2pm, before the AC does anything.
The roof shades the walls, the breeze has a path through the building, and the midday heat never got in to begin with. Guests step out of the sun and feel the temperature drop. The AC is there, and the room remembers how each guest likes it. It just has very little left to do.
Seaside Collective | Lombok
Nights that sound like the island.
Fewer compressors running means the soundscape belongs to the frogs and the rain. Guests sleep with the doors open because the night air is already right, and wake without that refrigerated-room dryness in their throat.
Somewhere Lombok
Water that smells like water. In the pool and in the glass.
Natural and mineral filtration does the work that heavy chlorine dosing usually does, so guests swim without stinging eyes or that faint bleach smell at dinner. And the drinking water is crafted on site, filtered and mineralised in-house, so there's no plastic bottle on the nightstand and no truck hauling water up the hill.
Begawan Biji | Bali
A landscape that feeds the kitchen. Because it's a farm.
Food grows in the landscape itself: real farms with real harvests, picked 40 meters from the table, with kitchen scraps going back in as compost. Rainwater gardens catch the storms and wastewater gardens clean what the resort uses. Guests walk through all of it thinking it's just beautiful planting.
Biorock reef, Gili Islands · Marionpinta, CC BY-SA 3.0
Travel that puts something back.
Guests can spend a morning building reef. On electrified structures like the Biorock reefs in the Gili Islands, a low current runs through a steel frame, minerals crystallise onto it, and coral grafts on and grows back faster, bringing the fish with it. It's the kind of program we steer our projects toward, where guests dive down and surface having left the reef bigger than they found it.
Private Luxury Residence | Lombok
Wellness that runs on the same thinking.
Sauna, ice bath, jacuzzi, mineral baths: all designed inside the resort's energy and water systems rather than bolted on next to them. The spa draws on the same engineering as the rest of the place, so the indulgence and the sustainability never have to be traded against each other.
What our clients say
Waterbom Bali · Eco-Mantra completed environmentally sustainable design for their park expansion and provides ongoing operational optimization.
Sayan Gulino
CEO
"They are a game changer for us, with a professional, scientific and strategic approach that balances ecology and business and delivers results. We've tried many other agencies, but the progress was painfully slow."
★ PATA Grand Award 2023 — Sustainability and Social Responsibility
Potato Head Family · Eco-Mantra built and runs their Zero Waste to Landfill program. Current result: 0.5% of waste goes to landfill.
Ronald Akili
Founder
"Eco-Mantra has been part of Potato Head since 2017. Their systematic approach to analyzing material flows across our operations and supply chain has had real results, helping us manage 98% of our waste responsibly, with only 2% going to landfill."
★ Eco Hotel Award — The World's 50 Best Hotels
Begawan Foundation & Como Shambhala Estate · Eco-Mantra completed sustainability design for Begawan Biji restaurant.
Bradley Gardner
Founder
"Most developers don't look at running costs over a building's full lifespan. Short-term thinking ends up costing more. Eco-Mantra goes beyond what's expected, and return on investment is always calculated to evaluate the viability of every sustainable system."

How we work
-
We start by understanding what sustainability means for your project: your stakeholders, your ambitions, what success looks like for this specific development. From there, we assess the site — its environmental conditions, risks, and the opportunities specific to your location. The outcome is a sustainability masterplan with clear targets, integrated into the design brief before architecture is fixed.
-
We work directly alongside your architects and engineers to integrate environmentally sustainable design (ESD) across passive cooling, energy, water, waste, materials, biodiversity, and microclimate — from the earliest concept decisions through to construction. Our approach combines ESD with integrated MEP engineering, so sustainability isn't layered on top of the design. It's the design.
-
For operational properties, we provide ongoing sustainability monitoring, optimisation, and advisory through our Eco Toolkit: a proprietary system for tracking resource consumption, identifying efficiency opportunities, and maintaining performance targets. The same approach that helped Waterbom Bali achieve waste to landfill of 0.03% and cut energy use at Potato Head Beach Club by 20%.
Our approach is one of a kind. So is every property we design.
The water systems, the passive cooling strategy, the relationship with the surrounding ecology, the materials: none of it is templated. Every solution is developed in close collaboration with the project's architects, shaped by the specific conditions of the site — its climate, its landscape, its community. The result is a property that could only exist here, built exactly this way. A competitive advantage no other property in the market can replicate.
Managing an existing property?
We can help
from here.
Not every project starts at concept stage. For operational properties, we offer a growing range of programs built around our Eco Toolkit — a proprietary system for measuring resource consumption, identifying efficiency opportunities, and tracking performance over time.
It starts with a conversation.
Whether you're just starting the design of a new property or looking to improve an existing property, we'd be happy to help you.
