Architectural Cases

The Key House, situated in the scenic Puerto Varas, Chile, represents a compelling exploration of architectural authenticity and regional identity. Conceived by the collaborative efforts of Lezaeta Lavanchy and Esteban Arteaga, this residential project, spanning 150 square meters and completed in 2025, stands as a testament to the idea that true architecture is intrinsically linked to its local environment. It embodies a design philosophy that not only integrates the structure seamlessly into its natural and cultural landscape but also elevates the traditional building materials, predominantly wood, to create a dwelling that resonates with its context. The house’s design carefully balances contemporary aesthetics with a deep appreciation for the inherent characteristics of its geographical location, making it a significant contribution to modern Chilean architecture.

At the heart of the Key House's design philosophy lies the principle articulated by Christian Norberg-Schulz: “The regional character is a property of any authentic architecture.” This sentiment guided Lezaeta Lavanchy and Esteban Arteaga in their approach to creating a home that is profoundly rooted in its specific setting. Puerto Varas, known for its stunning natural beauty and distinct cultural heritage, provided a rich source of inspiration. The architects meticulously studied the local vernacular, climate, and available resources to inform every aspect of the design, ensuring that the house not only exists within its environment but actively engages with it. The structure’s form, orientation, and material palette were chosen to maximize natural light, optimize thermal performance, and offer residents panoramic views of the surrounding landscape, fostering a strong connection between indoor and outdoor living spaces.

A defining feature of the Key House is its extensive and artful application of wood. This material, abundant in the region, is employed not merely for its structural properties but also for its aesthetic warmth and ecological sensibility. The thoughtful integration of various wood species, both in the exterior cladding and interior finishes, contributes to the house’s distinctive character and blends harmoniously with the natural surroundings. The architects’ choice of wood underscores a commitment to sustainable practices and a desire to create a dwelling that ages gracefully, reflecting the passage of time and the enduring beauty of its materials. This material focus, combined with innovative construction techniques, results in a residence that is both visually striking and inherently functional.

The Key House transcends the conventional definition of a dwelling, evolving into a sensitive dialogue between human ingenuity and environmental harmony. The architects' vision extends beyond mere shelter, aiming to create a living experience that celebrates the unique essence of Puerto Varas. Every design choice, from the strategic placement of windows to the selection of interior details, reinforces this dialogue, inviting occupants to partake in the narrative of the place. The project exemplifies a holistic approach to residential architecture, where the building becomes an extension of the landscape, and the inhabitants are continually reminded of their connection to the broader ecosystem.

Through its thoughtful design and material choices, the Key House by Lezaeta Lavanchy and Esteban Arteaga offers a compelling model for contemporary regional architecture. It demonstrates how a deep understanding and respect for local context can lead to creations that are both innovative and timeless, setting a benchmark for future residential developments in similar environments.

The Aerotim Hangar, conceived by the architectural studio +kouple, stands as a testament to innovative design, providing a specialized environment for Timur Fatkullin's acclaimed team of athletes and creative professionals. This facility in Ukraine, spanning 400 square meters and completed in 2025, goes beyond a conventional aircraft maintenance area, evolving into a vibrant hub for collaboration and inspiration. The design reflects the team's diverse pursuits, from aerobatics to film production, demonstrating a meticulous approach to creating a space that is both highly functional and aesthetically engaging.

Timur Fatkullin's Aerotim collective is renowned for its exceptional achievements in extreme sports such as aerobatics, freestyle motocross, and skydiving. Their commitment to exploring new frontiers has earned them significant accolades, including multiple GoPro Challenge championships and World Intermediate Aerobatics titles. Fatkullin himself balances a demanding schedule, which ranges from launching a jewelry collection with designer Valeriia Guzema to directing "Full Force," a feature film dedicated to Ukrainian Army Aviation. The concept of the hangar originated from Fatkullin's vision for a dedicated base that would accommodate the rigorous maintenance requirements of their sports aircraft while also serving as a central gathering point for his diverse team. The architects at +kouple readily embraced this challenging commission, recognizing its potential to push the boundaries of conventional hangar design.

The project presented numerous architectural and engineering challenges, marking it as one of the most intricate and rewarding ventures undertaken by the +kouple team. The design process focused on integrating robust industrial functionality with a comfortable, inspiring interior, creating a unique synergy that supports both technical operations and creative endeavors. The hangar's interior design thoughtfully incorporates materials and spatial arrangements that cater to the multifaceted activities of the Aerotim team, from intricate aircraft mechanics to brainstorming sessions for artistic projects.

The Aerotim Hangar represents a successful fusion of practicality and innovative design, tailored to the unique demands of a world-class team. It provides a state-of-the-art facility for maintaining high-performance aircraft while fostering a dynamic and inspiring atmosphere for creative collaboration. This project underscores the architectural firm's ability to deliver bespoke solutions that meet complex client needs, cementing its reputation for tackling demanding and engaging construction challenges.
