Timber structures under construction around mature trees on sandy ground

SUSTAINABILITY :

WATER, HEAT AND WASTE AT SIRITARAR

THE TREES WERE SURVEYED FIRST

Before the first drawing was made, an arborist walked the land and marked the mature trees that would stay. The house was drawn around them.

That decision, made at the beginning, shaped everything that followed.

WHAT THE HOUSE DOES EVERY DAY

Wastewater from the house treated on site and returned to the garden

THE HOUSE WATERS THE GARDEN

100% of the wastewater from the house is treated on site and returned to the garden. The trees are watered by the house. Nothing leaves the property.

Heat from the air-conditioning compressors making the hot water

HOT WATER FROM THE AIR CONDITIONING

Heat pulled out of the air-conditioning compressors is not thrown away. It makes the hot water for most of the house, with a back-up element for the times it cannot keep up on its own. All lighting is LED, and the interiors are drawn to work on daylight for most of the day.

Exterior walls of eco-block finished in pigmented cement, never painted

THE COLOUR IS THE MATERIAL

Designed for the island's climate, each structure sits to catch the sea breeze — raised roofs and shaded verandas move air through the house, and no building stands in another's wind. The exterior walls are eco-block, finished throughout with pigmented cement rather than paint, so the house is never repainted. No white was used anywhere, because white throws glare back at the eye.

Cleaning products and amenities decanted into refillable bottles

REFILLABLE, NOT DISPOSABLE

Every cleaning product in the house is biodegradable, because the water used to clean the house is the water that waters the trees. They arrive in bulk and are decanted into refillable bottles. Drinking water comes in refillable glass, and bathroom amenities are biodegradable and given on request rather than set out in advance, so nothing is opened that no one uses.

Waste sorted on site into food, glass, metal and paper

SORTED ON SITE

Food scraps are composted on site. Everything else is sorted at a station on the property, where guests can sort their own if they want to.

Thai species planted to need less water

PLANTED TO NEED LESS WATER

The planting is Thai species wherever it can be, because plants that belong in this climate hold up on their own and need far less water. The flowers and foliage arranged in the house are cut from the garden. No chemical treatments are used on the grounds.
