A research facility in the rainforest of West Sumatra, Indonesia.
Status: Under Construction (July 2025-present)

Nestled at the edge of Sumatra’s tropical rainforests, the Essential Oil Research Centre emerges from the island’s deep-rooted legacy in the spice trade. For centuries, cloves, nutmeg, cinnamon and black pepper travelled from these shores to the world; today that heritage continues through the sustainable cultivation and distillation of aromatic plants. Working in close partnership with PT Mitra Ayu — a world-class local producer that farms, sources and refines essential oils for the global market — Archigardener has designed a research facility that embeds production, research, teaching and communal life within a living landscape.

The architecture is conceived as an inhabited hilly terrain. Three storeys of angular, planted terraces rise like contour lines, supporting tropical herb species immediately outside the laboratories in which they are processed. The rational L-shaped plan organises oil-production labs, teaching spaces and meeting rooms so that every interior receives natural light and cross-ventilation from two sides while looking into an off-central courtyard. Activities within are placed on display; dynamic views of the building and the surrounding mountainous rainforest continually animate the spaces.

Over the entire concrete mountain stretches a semi-transparent steel roof canopy. This expansive tropical umbrella tempers the equatorial climate, transforming the roofscape below into a large semi-outdoor realm for everyday occupation and for gatherings of every scale. The canopy puts the monsoon itself on display. A 21-metre circular skylight gathers torrential rain and directs it into a 12-metre-tall rain-chain column. Water cascades through successive fern-filled steel rings before falling into a stepwell set within the central sheltered event plaza. During heavy rain the stepwell fills, then overflows through a precise slot channel into an infinity reflecting pool that in turn feeds rainwater storage tanks for reuse throughout the facility.

The angular terraces are linked between floors by continuous planted slopes, forming an amphitheatre that serves both as informal seating for talks and events and as a place for occupants to pause and eat. Zig-zag staircases woven into the hillscape provide the primary vertical circulation, turning every journey between levels into a short rainforest trek. Beneath the amphitheatre lie the tissue-culture facilities; low windows admit only indirect light rippled across a reflection pool outside, creating the controlled luminous conditions required for growth.

The overall square geometry of the building is flipped along the axis that intersects the main L-shaped volume. Along this line run the rotated lift core and the slot channel, drawing the eye outward to a dramatic framed vista of the wider essential-oil production campus and the mountainous rainforest beyond — a view held between the rain-chain column, the amphitheatre, the canopy and the infinity edge of the reflecting pool.

In this way the Essential Oil Research Centre becomes more than a workplace. It is a productive topography in which architecture, horticulture, water and climate perform together — a contemporary expression of Sumatra’s enduring relationship with the plants that have long defined its place in the world.
