The Aurora Greenhouse Restaurant is located near Sandvatn Lake in Reykjahlid, Iceland. The design merges a dining space with a greenhouse, allowing guests to enjoy Icelandic cuisine while immersed in the scenic beauty of the Myvatn region. The approach focuses on blending the building into its natural surroundings, capturing the essence of the landscape in the architectural form.

Architectural Integration

The design showcases a structure that rises from the ground, similar to traditional Icelandic turf houses. This method connects the building with the landscape and encourages a sense of belonging for those who visit. The greenhouse is designed with a stepped layout, which enhances light exposure essential for growing plants while creating a source of fresh ingredients for the kitchen.

Accessibility and Flow

Two main entrances offer paths into the restaurant—one at street level and another that leads to a green roof. This variety in access points improves the movement throughout the space, allowing visitors to engage with the outside environment. The arrangement reflects an understanding of how people navigate, making the building easy to explore and enjoy.

Spatial Organization and Functionality

Inside, the restaurant features high ceilings and large windows that frame views of the beautiful landscape. Glass walls separate the dining area from the greenhouse, inviting diners to experience the growth of their food firsthand. A multipurpose room, adaptable for many activities, has been designed with natural light in mind, thanks to the use of skylights that brighten the space throughout the day.

Materiality and Aesthetic

The materials used include dark wood, glass, and corten steel. Each of these plays a role in supporting the building's goals. Dark wood adds a touch of warmth, while glass facilitates connections between the interior and exterior environments. Corten steel introduces a modern aspect that complements the natural setting, providing a cohesive look that fits well within the rugged Icelandic landscape.

The building’s design features patterns and textures that resemble the local topography, creating an aesthetic that connects both visually and conceptually with its surroundings.

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.
