Volcanic Stone and Green Roof Blend in a Serpentine Hydroponic Oasis

Project in-detail

Constructed with volcanic stone and topped with a green roof, the serpentine greenhouse facilitates year-round hydroponic cultivation while enhancing awareness of sustainable agricultural practices.
5 key facts about this project
01
Constructed from local volcanic stone to enhance thermal performance.
02
Incorporates a serpentine layout that encourages visitor interaction with plants.
03
Features a green roof to promote biodiversity and natural insulation.
04
Utilizes passive solar design principles to optimize energy efficiency.
05
Includes educational spaces to demonstrate sustainable food production practices.

The Ouroboros greenhouse is located in a landscape shaped by volcanic activity and rich agricultural potential. It operates as a hydroponic facility, growing a variety of plants while also educating visitors about sustainable practices. Inspired by the symbol of the Ouroboros, the design conveys themes of circular life and interconnection with the environment, integrating the structure naturally into its surroundings.

Spatial Organization

The greenhouse’s layout is designed in a serpentine manner, guiding visitors through distinct functional areas including a mushroom farm, hydroponic sections, and food preparation spaces. The experience begins in a central courtyard that resembles a volcanic crater, creating an inviting atmosphere for exploration. As visitors make their way through the building, they encounter various zones that reveal the intricacies of plant growth and food production, encouraging a deeper appreciation of the ecosystem at play.

Sustainability and Climate Control

This structure incorporates passive solar design features that aim to optimize climate regulation and energy efficiency. The angle of the glass panels is carefully designed to follow the sun’s path throughout the year, thus maximizing natural light and warmth. The walls, built with stone and turf, act as thermal mass, absorbing heat during the day and releasing it at night. This design approach minimizes the need for artificial heating and cooling, ultimately supporting year-round plant growth while demonstrating a commitment to environmentally friendly architecture.

Materiality and Aesthetics

The materials chosen for construction show a strong connection to the local environment. The green roof enhances insulation and contributes to local biodiversity, while the volcanic stone walls blend with the landscape. The use of wooden beams and panels not only provides structural support but also adds warmth to the interiors, making the spaces more inviting. Each material serves multiple purposes, from functionality to aesthetics, reinforcing the idea of a harmonious relationship between architecture and nature.

In the dining area, large glass windows provide expansive views of the surrounding landscape, connecting visitors to their environment. This transparency allows natural light to fill the space, fostering a sense of openness. Visitors experience a continuous dialogue between the cultivated areas inside and the dynamic landscape outside, enhancing their appreciation of both the architecture and the environment.

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
