Dark Stone Structure Embracing Celestial Observation and Temporal Experience

Project in-detail

Set against a raw landscape, the dark stone structure serves as a celestial observatory that merges temporal experiences with astronomical observation, inviting visitors to engage deeply with the cosmos.
5 key facts about this project
01
Dark stone exterior enhances connection to the natural landscape.
02
Gnomon positioned at the zenith aligns with celestial navigation.
03
Circular pillars represent each hour, marking the passage of time.
04
Inner courtyard directly focuses on Ursa Minor for stargazing.
05
Low-level lighting guides visitors through the observational experience.

The design is situated in a rugged landscape that connects deeply with nature and the night sky. Its main purpose is to enhance the understanding of astronomical phenomena for visitors. The concept focuses on height, drawing viewers' eyes upward to create a link between the earthly experience and the vast cosmos above.

The Gnomon

At the heart of the design is the gnomon, a tall vertical element reminiscent of ancient astronomical tools. It is positioned at the center of the building to align with the celestial sphere's meridian axis. This setup not only allows for star observation but also directs visitors' attention toward significant constellations, especially Ursa Minor. The gnomon serves as a functional guide for viewing celestial movements, grounding this exploration in the surrounding environment.

Spatial Organization

The layout features a circular pathway lined with pillars that rise to eye level. These pillars create a relationship with time, as the shadows from the gnomon move across them. Each pillar represents an hour, helping visitors track time as they interact with the architecture. This design invites exploration, encouraging movement and engagement with both the structure and the stars above.

Atmospheric Experience

Entering the reception building, visitors find themselves in a dark stone interior that separates them from the outside world. This setting fosters contemplation, made more profound by subtle reflected lighting that highlights the inner courtyard. This courtyard opens up to the sky, providing a clear view of the stars. It effectively merges the architectural experience with the observation of celestial bodies, creating a meaningful interaction with the sky.

Materiality

Dark stone is used throughout the interior to enhance the reflective nature of the space. This choice creates a strong sense of identity for the design and aligns with themes of observation and thoughtfulness. The materials support the overall atmosphere, allowing the architecture to connect with the celestial themes it portrays.

Visitors are drawn from the ground to the heavens, their gaze shifting upward toward the stars. The design encourages a connection with the cosmos, enriching the experience of those who enter.

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.
