Villa Koppar: A Sustainable Architectural Marvel by Collaboratorio

Nestled in the breathtaking natural landscape of Kopparnäs, Inkoo, Finland, Villa Koppar is a testament to ecological and sustainable architecture. Designed by Collaboratorio, this eco-friendly residence seamlessly integrates with its surroundings while adhering to modern passive house principles. Located just 45 kilometers west of Helsinki, this 180 m² residence was completed in 2023.

Design Overview: A Fusion of Nature and Innovation

Villa Koppar consists of two main structures: the primary residence and a detached garage with a dependence. Perched on rugged, exposed rock formations and surrounded by bucolic landscapes, this passive house is a perfect blend of minimalist architecture and environmental consciousness.

The house was designed for a young, growing family with a limited budget, showcasing how sustainable design can also be cost-efficient. The construction employs prefabricated straw structures (Ecococon), offering excellent thermal insulation while reducing the carbon footprint. The façade is clad with Organowood spruce boards, a durable and eco-friendly material treated for longevity. Inside, clay plaster walls add a natural aesthetic while maintaining healthy indoor air quality.

Sustainability at the Core: Passive House Principles

Villa Koppar is heated geothermically, reflecting its commitment to renewable energy sources. This eco-conscious design aligns with passive house standards, ensuring energy efficiency without compromising comfort. Both floors are built using rammed earth materials (Luonnonbetoni), further enhancing thermal mass and energy performance.

Interior Design: Minimalism Meets Functionality

The interior of Villa Koppar embodies Scandinavian minimalism, with natural materials taking center stage. Wood and clay dominate the palette, creating a serene and cozy ambiance. The lighting solutions, provided by brands like FLOS and Luceplan, complement the minimalist aesthetic while emphasizing functionality.

The upper floor houses the living and dining areas, including a landscape sauna that opens to panoramic views of the rocky terrain. Large windows and an extended terrace bring the outdoors in, allowing the residents to connect with the surrounding environment. The bedrooms are situated on the ground floor, with direct access to the garden, offering a seamless transition between indoor and outdoor spaces.
