Xavier De Kestelier: Designing Homes Beyond Earth

How can we build sustainable homes on other planets? This question was at the heart of a public lecture held at TU Wien, where Xavier De Kestelier, Global Head of Design at Hassell and a leading figure in space architecture, offered fascinating insights into designing human-centered habitats beyond Earth.

In his talk, Xavier De Kestelier emphasized the unique role architects play in space exploration: bringing together complex scientific and engineering disciplines into a single, coherent vision—one that keeps human needs at the core, even in the most extreme environments. His lecture illustrated how architecture, engineering, and science must work hand in hand to create livable, sustainable habitats in space.

Xavier De Kestelier presented three pioneering projects that exemplify this interplanetary approach. He led Hassell’s award-winning entry for NASA’s 3D-Printed Habitat Challenge for future Mars missions. The concept relies on autonomous robotic systems that construct protective shells from local Martian soil, enclosing inflatable living modules equipped for work and daily life. Designed as more than a survival shelter, the habitat aims to provide explorers with a true “home away from home.”

Turning to the Moon, Xavier De Kestelier introduced the ESA-backed Lunar Masterplan, which envisions a scalable village for long-term habitation. Developed in collaboration with anthropologists, psychologists, and other specialists, the concept prioritizes human well-being and social interaction. Communal spaces such as restaurants, sports facilities, and greenhouses are integrated into a settlement built from interlocking, 3D-printed lunar soil modules that provide radiation protection and allow the village to grow sustainably over time.

In low-Earth orbit, Xavier De Kestelier discussed his work on Sierra Space’s LIFE Habitat—an inflatable, two-story module designed to support a crew of six. Equipped with laboratories, sleeping quarters, a galley, exercise facilities, and even an “Astro Garden” for growing fresh crops, the habitat reflects a strong human-centric philosophy. A streamlined interior design and a central social hub, including a microgravity-friendly communal table, encourage connection and quality of life in space.

Across all three environments—Martian terrain, lunar surface, and orbital microgravity—Xavier De Kestelier demonstrated how architectural solutions must adapt to their specific contexts while adhering to shared principles: interdisciplinary collaboration, closed-loop sustainability, and a deep commitment to human well-being under extreme conditions.

The lecture also highlighted how space architecture can inform sustainable design on Earth. The constraints of space demand efficient resource use and circular systems—approaches that can help create more resilient and sustainable built environments at home. The event offered an inspiring glimpse into humanity’s future beyond our planet and underscored how designing for space can drive innovation for a greener future on Earth.
