About Maison KN

Located within the historic core of Hanoi, Maison KN stands as a distinctive dwelling amidst the city’s dense urban landscape. Designed by NGHIA Architect in 2023, this house emerges as a remarkable response to the challenges of its vibrant neighborhood.

Adapting to the Constraints, Embracing the Possibilities

Commissioned for the grown children of a longstanding Hanoi family, Maison KN was conceived to provide a future-proof living space that addresses the constraints of the former neighborhood. The design brief called for a self-contained, inward-focused residence that ensures both openness and comfort, seamlessly integrating living, working, and leisure spaces.

Capturing the Essence of Chaos and Tranquility

The facade of Maison KN reflects the surrounding area’s visual complexity, with a design that mimics the non-linear contours of the rooftops. This interplay of solid and empty patches creates a unique visual identity, offering different perspectives from each floor. The interior space is highlighted by the captivating garden on the 3rd floor, where a floating walkway connects the two levels, blending the indoor and outdoor environments.

Embracing Sustainable Living

Maison KN is not only a visually striking residence but also a testament to sustainable living. The strategic use of natural light and ventilation, coupled with a rainwater harvesting system and organic fertilization, enables the house to thrive as a self-sustaining ecosystem. The lush greenery cultivated within the unique microclimate serves as an ecological sanctuary, contributing to a truly lavish living experience.

A Harmonious Intersection of Design and Function

Maison KN’s design seamlessly unites form and function, creating a dwelling that is not only aesthetically pleasing but also highly practical. The thoughtful integration of living, working, and leisure spaces, along with the strategic use of natural resources, elevates this house to a new level of sustainable and future-proof living in the heart of Hanoi.
