GE House by Alventosa Morell Arquitectes: A Sustainable Home in Osona, Spain

A Harmonious Blend of Nature and Architecture

Located in the picturesque village of Seva, within Osona, Spain, GE House by Alventosa Morell Arquitectes is a stunning example of sustainable residential design. Nestled near Montseny Natural Park, this 110 m² home embraces energy efficiency, natural materials, and bioclimatic principles to create a warm, inviting living space with minimal environmental impact.

Strategic Site Planning and Orientation

The house is situated on a triangular-shaped plot bordered by two streets, featuring a natural slope that influenced the design. The architects strategically placed the structure on the higher, flatter section of the plot, ensuring optimal sunlight exposure and minimizing earthwork. The entrance is positioned to the north, allowing for a seamless connection between indoor and outdoor spaces.

Innovative Architectural Design for Privacy and Comfort

The design prioritizes open yet intimate spaces, balancing transparency with privacy. A structural system of wooden porticos divides the home into two distinct sections:

• Northern Zone: Enclosed, flat-roofed spaces house the wet areas, including bathrooms and service rooms.
• Southern Zone: A light-filled, open-plan living space under an inclined roof contains the porch, living room, dining area, kitchen, and bedrooms, all facing the garden to maximize natural light and scenic views.

To enhance the feeling of openness, the facades are designed with ceramic materials, providing a solid, protective character. However, instead of extending to the full height of the home, they only reach window sill level, maintaining privacy while allowing ample sunlight.

A defining element of the design is the floating wooden “hat”, formed by a ventilated black-tinted wooden facade and black-tiled roof, visually separating the living space from the ceramic base while reinforcing the home’s distinctive architectural identity.

Bioclimatic Design for Energy Efficiency

GE House integrates passive solar design, significantly reducing its energy demand. Key sustainability strategies include:

• South-facing solar capture for natural heating during winter.
• Strategic shading to prevent overheating in summer.
• High-performance thermal insulation with cellulose-based materials.
• Cross-ventilation system, utilizing skylights and main facade openings for natural airflow.

Thanks to these bioclimatic principles, the home eliminates the need for conventional cooling systems, relying solely on a single pellet stove for winter heating.

Eco-Friendly Materials and Sustainable Construction

To further reduce its carbon footprint, GE House incorporates environmentally responsible materials and construction techniques:

1. Sustainable Wood Usage: PEFC-certified pine wood is used for the roof, windows, interior finishes, and facade cladding.
2. Cellulose Insulation: Provides high thermal efficiency while being eco-friendly.
3. Biomass-Fired Ceramic Work: A sustainable alternative to traditional construction materials.
4. Preservation of Existing Trees: The design respects and incorporates the natural landscape, maintaining biodiversity.
