Dragon House: A Visionary Sustainable Home Renovation by no.ma architecten

The Dragon House in Belgium, transformed by no.ma architecten, exemplifies the potential of sustainable home renovation. This project reimagines an outdated structure into a dynamic and energy-efficient family home, blending flexibility, environmental responsibility, and innovative design. By integrating a high-performance insulation shell and upcycled materials, the architects create a residence that fosters both spatial fluidity and a strong connection to its natural surroundings.

A New Architectural Identity

Originally purchased for its location overlooking Vlierbeek Abbey rather than its design, the house lacked spatial connectivity and engagement with the outdoors. The renovation process introduced a new volume atop the existing basement floor, allowing for an entirely redefined architectural composition.

The design introduces split-level arrangements, diagonal sightlines, and carefully positioned window openings to dissolve the boundaries between indoor and outdoor spaces. This strategic spatial planning not only enhances natural light penetration but also maximizes scenic views while maintaining privacy. By alternating between opaque and glass surfaces, the house carefully controls its visual relationships with the surroundings, ensuring both openness and seclusion where necessary.

Sustainable Materials and Passive Energy Strategies

A key aspect of this renovation is its dedication to sustainability. The exterior features a pioneering use of plastic diamond slats—a first in Belgium—following the upcycle principle. These elements contribute to both environmental responsibility and aesthetic appeal, offering a unique interplay of shading and color variations.

Passive sun protection is seamlessly incorporated through extended canopies, which shelter the bike port and terrace while fostering greenery at upper levels. These design elements regulate indoor temperatures by reducing direct solar exposure, minimizing the need for mechanical cooling. The rear façade, equipped with expansive sliding windows, further enhances energy efficiency by facilitating cross-ventilation and seamless indoor-outdoor integration.

Inside, the material palette continues this sustainable ethos. White walls contrast with exposed steel girders and wooden beams, while the flooring selections include red-pigmented concrete and vibrant red vinyl. Oak veneer cabinetry and green-painted furniture elements introduce warmth and character, reinforcing the home’s bold yet harmonious aesthetic.

Flexible and Functional Living Spaces

The Dragon House is designed for adaptability, ensuring that spaces can evolve alongside the needs of its occupants. Upon entry, the home immediately establishes its multi-level character. A conventional staircase ascends to the upper floors, while a gradual, "lazy" staircase descends to the kitchen, positioned at backyard level.

This central kitchen space integrates practical storage solutions, where cabinetry seamlessly incorporates access to the basement’s technical room and guest facilities. The sunken living room, connected to the kitchen via flowing red-pigmented concrete steps, offers an intimate yet open gathering area. A built-in desk beneath the staircase optimizes space efficiency while maintaining a visual connection with the rest of the home.

On the second floor, the children's bedrooms, a bathroom, and an additional toilet maintain the home’s commitment to flexibility and natural light. A distinctive feature is the void above the kitchen, where a trap net stretches across the space, creating both an engaging play area and a means of enhancing spatial openness. This design choice allows sunlight to filter deeper into the home, further reinforcing the interplay between different levels.

A Model for Sustainable Home Renovation

Dragon House is a testament to the transformative power of sustainable home renovation. By integrating upcycled materials, passive energy solutions, and spatial ingenuity, no.ma architecten redefine how existing structures can be adapted for modern living.

This project demonstrates that sustainability and architectural innovation can go hand in hand, proving that an old house can become an inspiring, high-performing home without sacrificing character or environmental responsibility. With its bold material choices, flexible layouts, and energy-efficient strategies, Dragon House serves as a model for future residential renovations, inspiring homeowners and architects alike to embrace sustainability as a driving force in design.
