Clos des Hêtres

Located on the heights of Lausanne, Switzerland, the site is characterized by its existing vegetation, notably its remarkable protected beech trees. In order to preserve this unique feature and enhance this natural heritage, a thorough analysis was carried out in collaboration with a specialist to identify the trees to be retained prior to the project design phase.

Responding to the need for sustainable and high-quality urban densification, RDR Architectes proposes the construction of three residential buildings designed to provide a pleasant and green living environment within an urban context. These new three-story buildings are harmoniously integrated into the natural slope of the site in order to offer open views. Their composition and staggered layout contribute to the integration of the volumes within the scale of the surrounding built environment.

The south-west orientation of the buildings optimizes natural sunlight, while generous openings allow light to flow smoothly throughout the interior spaces. Offering a variety of apartment typologies ranging from 2.5-room to 5.5-room units, including several duplexes, all apartments benefit from private outdoor extensions in the form of balconies or terraces — true living spaces directly connected to the surrounding greenery. The constant relationship between the living spaces and the landscape context also preserves the privacy of each dwelling.

Beyond regulatory compliance, the constructive, technical, and energy-related choices express a genuine commitment to placing sustainability at the heart of the project. The development incorporates a hybrid timber construction system. Renewable energy production is ensured through geothermal probes and photovoltaic panels.

As a natural material echoing the character of the neighborhood, wood is prominently featured in the façade design and pergolas, giving the ensemble a strong and coherent visual identity.

Designed as a place for social interaction and relaxation, the heart of the plot is transformed into a landscaped park featuring play areas and shared vegetable gardens. Rainwater harvesting contributes to the maintenance of these green spaces.

By prioritizing landscaped outdoor areas, the development benefits from an underground parking facility with 17 parking spaces, complemented by two outdoor parking spaces and dedicated bicycle parking areas.

Certified Minergie-ECO, the development combines energy performance and accessibility with thermal and acoustic comfort, contributing to the well-being and comfort of its residents.
