Thermal Inertia and Glazed Sunspaces in a Greenhouse-Restaurant Blend

Project in-detail

Constructed with thermal inertia walls and integrated glazed sunspaces, this design harmonizes with the Northeast Iceland landscape to serve as a greenhouse and restaurant.
5 key facts about this project
01
Incorporates thermal inertia walls for improved energy efficiency.
02
Features glazed sunspaces designed to capture natural light.
03
Utilizes a dual volume approach with distinct greenhouse and restaurant functions.
04
Draws inspiration from traditional turf houses to integrate with the landscape.
05
Includes a partially buried structure to enhance thermal stability.

The project is situated in Northeast Iceland, where the landscape plays a significant role in its design. It features two main volumes: a greenhouse and a restaurant. The concept emphasizes the relationship between buildings and their natural surroundings, focusing on sustainability and ecological awareness. The goal is to integrate the architecture into the landscape while enhancing the experience for users.

Orientation and Spatial Organization

The restaurant is located to the southwest, allowing for extensive views of the Hverfjall volcano. This orientation provides a visual focal point for visitors. Service areas are carefully positioned in directions that minimize exposure to cold winds, ensuring comfort throughout the space. The entrance plaza is defined by high walls that shield the building from harsh air, leading to a covered atrium. This atrium serves multiple purposes and encourages social interaction among visitors.

Bioclimatic Strategies

Attention to bioclimatic techniques is evident in the design. Living spaces are oriented to maximize sunlight, while walls are constructed with high thermal inertia to reduce heat loss. Portions of the structure are partially buried to create a stable indoor climate. Vegetated roofs contribute to energy efficiency and provide additional insulation. Outdoor areas are designed to create sheltered spaces, offering respite from wind and cold.

Connection to Nature

The design enhances the connection between indoor and outdoor spaces. Glazed sunspaces allow natural light to enter, providing warmth during colder months. This approach creates a welcoming atmosphere and comfort throughout the year, making the interior more inviting.

Vernacular Architecture Influence

The project draws inspiration from traditional turf houses, reflecting local architectural practices. Softly sloping roofs mirror the contours of the landscape and provide practical protection from the wind. This design choice reinforces the connection to the site and highlights the project's commitment to blending with its environment.

The careful integration of form with the landscape allows for a harmonious relationship between nature and architecture. Light and shadow play across the building's surfaces, enriching the experience of both the design and the surrounding environment. This thoughtful approach creates spaces that invite exploration and engagement with the landscape, ensuring that the architecture complements rather than competes with its natural context.

`
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.
