Buildner Iceland Slow Sauna Competition: Innovative Designs for Volcanic Landscapes

Buildner, in collaboration with Slow Travel Mývatn, recently concluded its Iceland Slow Sauna architectural competition, seeking designs for a compact sauna and greenhouse retreat seamlessly integrated into the volcanic surroundings of Lake Mývatn. The competition encouraged architects and designers to explore how elements like warmth, illumination, plant life, and the natural environment could define an intimate space for rejuvenation and immersion in nature. Emphasizing the Icelandic bathing traditions focused on tranquility and restoration, the brief called for innovative approaches to combine these functions within a single architectural experience.

The submitted projects frequently featured themes such as adapting traditional Icelandic building forms, using understated material palettes, implementing passive environmental strategies, and creating thoughtfully designed interactions with the landscape. Many designs went beyond the sauna experience itself, incorporating the greenhouse as a space for cultivation, cooling, relaxation, and contemplation. The most successful proposals illustrated that a small-scale brief could yield significant architectural impact through careful consideration of proportions, spatial arrangements, material choices, and the precise control of transitions between varied environmental conditions.

Prizewinning Concepts and Architectural Innovation

The winning entries of the Iceland Slow Sauna competition demonstrate exceptional creativity and sensitivity to the unique Icelandic landscape. The First Prize, awarded to 'Linear Ritual' by Prusha Kadir, Joel Jansson, and Emil Sandström, reimagines a compact retreat that harmoniously extends the existing homestead. This design organizes its program as a linear progression, guiding visitors through distinct zones for arrival, greenhouse, shower, and sauna, with each step subtly altering temperature, humidity, light, and views. Drawing inspiration from traditional Icelandic structures, its steep roof profile is adapted to withstand the local climate, while creating elevated interior spaces. The design emphasizes durability and buildability through timber construction, straightforward detailing, and a minimalist material palette. By blending hospitality, bathing, and food production within a modest footprint, 'Linear Ritual' establishes a clear spatial narrative where environmental shifts are central to the building's experience.

The Second Prize went to 'Slow Sauna - Descent into Stillness' by Jeremy T Anderson and Pascal Henle, which frames the bathing experience as a gradual immersion into the Icelandic terrain. This project transcends the conventional sauna design by orchestrating movement, enclosure, and fluctuating environmental conditions as integral parts of the ritual. A translucent double-skin envelope encases a compact interior, modulating light, weather, and views, thereby softening the building's presence within the volcanic environment. Inside, circular spaces offer a contrast to the rectilinear outer shell, creating focused areas for bathing, cleansing, and quiet reflection. The proposal combines a subdued material selection with a modular structural framework, balancing atmospheric depth with practical construction. Through its focus on descent, softened light, and spatial transitions, this design transforms the sauna into an immersive journey rather than a static destination.

Sustainability and Experiential Journeys

The Third Prize, 'The fourfold ritual' by Marty Ilievski and Clément Vignes, proposes a compact retreat where the sauna is interpreted as a sequence of interconnected elemental encounters. This design centers around a timber sauna as the thermal core, enveloped by a translucent greenhouse that provides spaces for cooling, relaxation, cultivation, and circulation, all within a unified environmental shell. The project explores the interplay of earth, fire, water, and air, using changes in temperature, humidity, vegetation, and daylight to guide movement through the interior. Adopting familiar Icelandic vernacular forms, the proposal combines simple construction with a layered 'box-within-a-box' arrangement. This new volume connects to the existing house while maintaining a strong relationship with the volcanic landscape, crafting a concise spatial journey that oscillates between enclosure and openness, warmth and coolness, and darkness and natural light.

The Buildner Sustainability Award was presented to Jordan Paul Scheuermann for 'Iceland Slow Sauna,' a project that reinterprets the traditional Icelandic baðstofa as a versatile retreat. This design integrates a sauna, greenhouse, workshop, and recovery areas within a single architectural volume. It merges vernacular forms with contemporary environmental strategies, featuring a steeply pitched timber structure enclosed by a translucent polycarbonate skin. This skin captures solar heat, shelters plants, and creates a thermally buffered zone around the sauna. The project's orientation and sectional organization are carefully planned to respond to the volcanic landscape, prevailing winds, solar exposure, and the protective qualities of an existing berm. Rather than a singular destination, the proposal connects preparation, bathing, cultivation, recovery, and reflection through a series of interconnected spaces. This holistic system uses architecture and environmental performance to offer a broader definition of wellness, deeply rooted in Iceland's climate, landscape, and building traditions.

Julianakerk Church Transforms into Modern Residential Project JUUL

In a remarkable act of architectural revitalization, the Julianakerk church, which suffered severe damage from a fire almost a decade ago, has been reborn as the JUUL residential complex in Rotterdam's picturesque Heijplaat garden village. This ambitious undertaking by HA-HA Design & Development has transformed the charred remnants of the old church into four distinct modern residences, symbolizing renewal and progress.

This project stands as a testament to innovative adaptive reuse, skillfully integrating the historical essence of the church with contemporary living needs. The design philosophy behind JUUL emphasizes sustainability and a thoughtful engagement with the site's past, creating living spaces that are both unique and environmentally conscious. The conversion not only provides new homes but also preserves a significant piece of local heritage, demonstrating how damaged historical structures can be given a vibrant second life.

The successful completion of the JUUL project highlights the potential for blending historical preservation with modern urban development. It serves as an inspiring model for communities grappling with derelict heritage sites, showing that with creative vision and dedicated effort, forgotten places can once again become integral and cherished parts of the urban fabric. Such transformations encourage a deeper appreciation for history while forging pathways to a more sustainable future.

Luxembourg Pavilion to Address Residential Overconsumption at 2027 Venice Biennale

A panel of distinguished art and architecture professionals has recently unveiled the selected curatorial proposal for the Luxembourg Pavilion at the upcoming 2027 Venice Architecture Biennale. The chosen exhibition, titled "Excess! On the Overconsumption of Living Space," will be spearheaded by housing specialist Céline Zimmer and architects Bùi Quý Sơn and Paul-Antoine Lucas, co-founders of the acclaimed spatial practice Exutoire.

Luxembourg Pavilion to Spotlight Housing Overconsumption and Global Disparities at 2027 Venice Biennale

On September 30, 2026, a distinguished jury of art and architecture experts officially announced the curatorial team for the Luxembourg Pavilion at the 2027 Venice Architecture Biennale. The exhibition, entitled "Excess! On the Overconsumption of Living Space," will be curated by housing expert Céline Zimmer and architects Bùi Quý Sơn and Paul-Antoine Lucas, co-founders of Exutoire, a critical spatial practice recognized with an ArchDaily 2026 Next Practices Award. This thought-provoking display will be housed on the first floor of the Sale d'Armi in the historic Arsenale, opening its doors to the public on May 8, 2027.

The core of the exhibition’s message revolves around the uneven distribution of living space, identifying it as a symptom of broader patterns of excess contributing to contemporary housing and ecological challenges. The curators aim to spark a vital discussion by juxtaposing the housing landscapes of Luxembourg, one of Europe's wealthiest nations and a constitutional monarchy, with those of Vietnam, a rapidly developing Communist state in Southeast Asia. This comparative analysis seeks to highlight contrasting realities and foster a deeper understanding of spatial consumption from diverse global perspectives. The curatorial team brings a wealth of experience, incorporating insights from housing systems, social justice in design, and queer theory within architecture to enrich the exhibition's narrative.

The 20th edition of the Venice Architecture Biennale, running from May 8 to November 21, 2027, is themed "Do Architecture — For the Possibility of Coexistence Facing a Real Reality," curated by Wang Shu and Lu Wenyu of Amateur Architecture Studio. The Luxembourg Pavilion's contribution will stand alongside other national presentations, including Germany's "CONVIVERE," which explores coexistence and democracy; Ukraine's "Pool of Questions," addressing displacement and shared space; and Türkiye's "Spolia Futures," focusing on reuse and memory.

This initiative represents a critical moment for architectural discourse, offering a platform to scrutinize how our societies inhabit and consume space. By drawing parallels between Luxembourg's high per capita housing floor area and Vietnam's rapid growth, the exhibition promises to unveil profound insights into the complex interplay of economic development, social equity, and environmental sustainability in shaping our built environment.
