Circular Residence With Polycarbonate Facade and Central Greenhouse Integration

Project in-detail

A circular structure with polycarbonate panels envelops a central greenhouse, creating a seamless connection between indoor and outdoor environments for a sustainable family residence.
5 key facts about this project
01
Circular design enhances natural light distribution throughout the living spaces.
02
Central greenhouse functions as a microclimate for native plant integration.
03
Polycarbonate panels provide adjustable ventilation while maximizing transparency.
04
Locally sourced materials minimize transportation emissions and support the economy.
05
Passive solar strategies reduce energy consumption for heating and cooling.
The project in question is an architectural design situated in Lanzarote, Spain, known as the "Sundial." This dwelling is characterized by its circular configuration, designed to harmonize with the natural landscape and climate of the region. The structure functions as both a residence and an interactive element with its environment, emphasizing sustainable practices and energy efficiency. The architectural design prioritizes natural light and views, establishing a direct connection between the indoor spaces and the external landscape.

The layout consists of a central atrium surrounded by living quarters, creating a fluid and open spatial arrangement. The circular shape enhances the distribution of light and air throughout the home, providing a comfortable atmosphere for its occupants. Each segment of the dwelling caters to different functions, including sleeping, living, and utility areas, while the atrium serves as a natural greenhouse and ecological space.

Integration with Natural Elements
One distinctive feature of the Sundial project is its unique approach to integrating natural elements into the design. By utilizing a ring-shaped structure, the dwelling aligns itself with solar paths, allowing for optimal sunlight penetration throughout the day. This orientation enables passive solar heating and cooling, minimizing energy consumption and promoting environmental sustainability.

The central atrium, planted with native vegetation, acts not only as a source of natural light but also as a habitat for local wildlife. The integration of greenery reflects a commitment to enhancing biodiversity, ensuring that the design contributes positively to the surrounding ecosystem. This approach distinguishes the project from conventional residential designs by merging architectural function with ecological responsibility.

Material Choices and Sustainability
The materials selected for the Sundial project support both durability and aesthetic appeal. Concrete forms the primary structure, offering strength and stability. Large glass panels are strategically placed to maximize views and natural light, while lightweight polycarbonate sections allow for adjustable ventilation. The use of wood adds texture and warmth, connecting the interior spaces to the natural environment outside.

The architectural planning emphasizes the use of locally sourced materials, reducing transportation emissions and supporting the local economy. This focus on sustainability is a defining characteristic of the design, ensuring that the dwelling not only meets the needs of its occupants but also contributes to the conservation of the region’s resources.

For further exploration of this project and to gain insights into its architectural plans, sections, and detailed designs, interested readers are encouraged to review the complete project presentation. Examining these elements will provide a deeper understanding of the architectural ideas that inform the Sundial's innovative design.

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
