Local Stone and Natural Zinc Embrace a Spiraled Community Space

Project in-detail

Embedded within a sloped landscape, the use of local stone and natural zinc creates a spiraled community space that accommodates both dynamic activities and reflective gatherings.
5 key facts about this project
01
This design features a spiral layout based on the golden ratio.
02
Flexible partitions allow for adaptable space configurations.
03
Natural zinc cladding is used for roof materials.
04
The lower zone is intentionally dug into the ground for thermal regulation.
05
Local stone connects the structure to its regional context.

The design focused on the Spirala community is set in a sloped landscape, integrating with its surroundings. The placement evokes images of ancient fossils and Greek theaters, hinting at both permanence and a space for gathering. The layout follows a spiral inspired by the golden ratio, allowing it to serve various functions that accommodate both individual and group activities.

Design Configuration

The arrangement creates different areas tailored for specific uses. One section benefits from ample natural light, ideal for dynamic pursuits like dance and yoga. The other zone is more enclosed, providing a quieter environment for static activities such as performing arts classes or conferences. This clear separation encourages movement in one area while fostering reflection in another.

Circulation and Flexibility

The design enhances movement within the space with movable partitions that allow for flexible interactions. These partitions support a variety of communal activities and enable shifts in the layout as needs change. Overall, the structure works well for larger gatherings while still providing spaces that feel private and personal.

Materiality and Regional Context

Local materials are chosen carefully to reflect the regional context. The use of local stone for the exterior ties the building to its landscape. Wooden posts create a strong framework that supports the roof, which is covered in natural zinc. These materials connect the design to traditional agricultural buildings in Portugal, and they also help manage temperature, keeping the interior comfortable year-round.

Steps leading into the lower zone create intimate areas for gatherings and connect users to the earth around them. This feature reinforces a relationship with the landscape, blurring the lines between indoors and out.

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.
