At its structural core, W7SKY incorporates the WEISSENSEER HSB Standard—a hallmark of eco timber construction that reflects 95 years of engineering and innovation excellence. As an international pioneer in passive and plus-energy building standards, the Weissenseer Group has realized flagship projects across the globe, setting benchmarks for sustainable, future-oriented architecture.
W7SKY marks a defining milestone: the first “Very Home Edition of WEISSENSEER ”—a design-forward residential expression rendered and realized by the Weissenseer team.

As part of this commitment to innovation and excellence, another pioneering element from the Weissenseer Group portfolio is seamlessly integrated into W7SKY: the Boxxes bathroom modules.
BOXXES – CHRISTOF JR
Developed and led by Christof Jr., son of Christof Weissenseer, Boxxes represents a new generation of entrepreneurial thinking—rooted in innovation while continuing a strong family tradition of precision, quality, and forward-looking design.
The result is a harmonious synthesis of efficiency, aesthetics, and comfort. Each bathroom is conceived as a refined spatial experience—highly functional and meticulously engineered, yet sensorial in presence. Defined by production efficiency and limitless execution standards, Boxxes bathrooms set new benchmarks for contemporary living environments.


W7SKY – Design Language & Aesthetic
The predominant style of the W7SKY Estate is rooted in vintage design, infused with a nostalgic, character-driven charm. Hand-selected vintage furniture and décor bring depth, warmth, and authenticity to each space. Every piece carries a story—adding soul, texture, and a quiet sense of history that gives the interiors their distinctive identity.
This timeless foundation is thoughtfully paired with selected interior design languages, most notably Modern Mediterranean style. Inspired by the warmth, elegance, and relaxed sophistication of Mediterranean living, these influences are reinterpreted through a contemporary, curated lens—where heritage and modernity coexist in balance.
At W7SKY, we also embrace the philosophy of Wabi-Sabi—the Japanese aesthetic that finds beauty in imperfection, simplicity and the natural world. This sensibility is reflected in our use of natural materials and timeless textures. Raw wood and stone appear in their most organic, unprocessed forms, combined with minimalist clarity, where every element serves a purpose and invites calmness, light, and spatial breathing room.
Functionality plays an equally essential role. Drawing from Midcentury Modern principles, our interiors prioritize intelligent, user-friendly design. Form follows function—each piece is practical, efficient, and thoughtfully proportioned, proving that utility and elegance are not opposing forces, but complementary ones.
To ground the spaces with an urban edge, we integrate elements of Industrial Design. Raw concrete, exposed brick, steel, and reclaimed wood introduce honesty and structure, blending the industrial with the organic to create environments that feel both sophisticated and authentic.
Finally, W7SKY is energized by the bold spirit of Art Deco. Geometric forms and vibrant, expressive color accents appear throughout furnishings, surfaces, and details—adding confidence, rhythm, and artistic flair to the overall composition.
Together, these influences form a layered, cohesive design language—where past and present, restraint and expression, function and emotion converge to create spaces that feel curated, lived-in, and unmistakably W7SK

Our External Partners – the Craftmanship
W7SKY is the result of a collective effort —shaped and elevated by exceptional external partners whose contributions have been truly invaluable to the project.
We extend our sincere appreciation to the creative tandem from Original in Berlin—Lars Triesch and Nico—passionate architects and dedicated vintage design collectors whose depth of expertise and curatorial sensitivity have enriched W7SKY in profound ways. Their instinctive understanding of the visual language and atmospheric mood defined for the project was remarkable, translating vision into substance with clarity, creativity, and intelligence. Their input consistently resulted in thoughtful, top-tier solutions that balanced creative expression with functional precision.
We are grateful to our local craftsmen, whose work brings tactility and authenticity to every space. In particular, Peter Krainer, whose bespoke carpentry—from custom-designed tables to sideboards and built-in elements—was carved and tailored specifically for W7SKY, embodying craftsmanship at its finest.
Further depth was added through the expertise of local textile and fabric specialists, who curated design sheets, tapestries, carpets and curtains that elevate each interior with texture, warmth, and nuance.
Our appreciation also extends to Vienna-based art collectors—especially Sava Arts—as well as artisan workshops and master framers, whose refined eye and craftsmanship ensured that each artwork is presented with the respect, precision, and presence it deserves.
Together, these collaborations form the cultural and material fabric of W7SKY—where shared values, craftsmanship, and creative rigor converge to create spaces of lasting character.
