Modern Home Renovation in Spain: Maria i el Pablo House by OBO Estudi

The Maria i el Pablo House, a standout example of modern home renovation in Spain, showcases the innovative approach of OBO Estudi to adapt a self-built house into a sustainable, family-friendly space. Located in the La Floresta neighborhood of Sant Cugat del Vallès, this renovation project seamlessly integrates functionality with aesthetic appeal while respecting the natural surroundings.

Project Overview: The Transformation of Maria i el Pablo House

The house is a blend of old and new, with its first phase focused on achieving the immediate habitability required by a young couple and their growing family. Initially constructed as a self-built home, it was positioned on a rugged topography with two distinct platforms. OBO Estudi’s renovation aimed not only at enhancing the functionality of the space but also at improving its relationship with the surrounding natural environment.

Design Challenges and Initial Adaptations

Site Constraints: Rugged Topography and Limited Sunlight

The property’s location presented several challenges, especially with regard to sunlight exposure. The upper platform of the house, nestled next to a slope, was shaded during most of the winter months. To address this, the architects leveraged the natural topography to create two distinct zones—one for storage, a vegetable garden, and parking, and another for living spaces and a garden with a swimming pool.

Sustainability and Insulation: A Focus on Energy Efficiency

One of the primary concerns for OBO Estudi was thermal comfort. Since the house faced prolonged periods of winter shade, the original owner had already invested in high-quality insulation in the roof and facades. However, the renovation further enhanced energy efficiency by upgrading the heating system and introducing new carpentry that optimized insulation without compromising the aesthetic appeal of the house.

Renovation Process: From Quick Habitation to Future Expansion

Phase One: Quick Occupancy and Functional Modifications

The first phase of the renovation focused on quickly making the house livable. OBO Estudi introduced wooden partitions that created privacy within the open-plan structure, allowing the family to settle in while maintaining an open, fluid connection between communal spaces. These partitions were also designed to be flexible, enabling future modifications when the house was expanded.

Phase Two: Expansion to Accommodate a Growing Family

With the arrival of a second child, the renovation entered its second phase: the extension of the house. Two new volumes made from thermal clay were added, not only to provide additional space but also to improve thermal insulation. These extensions were designed to harmonize with the original materials, preserving the aesthetic unity of the structure while ensuring a comfortable living environment year-round.

Innovative Architectural Features: Integration of the Outdoors

The Second Skin: A Pergola and Hemp Rope Lattice

A key feature of the renovation is the introduction of a second skin to the house: a lightweight metallic structure and a lattice of hemp ropes that form a pergola. This structure provides an intermediate space between the interior and exterior, allowing for better interaction with nature.

Deciduous Vines for Seasonal Shade

To enhance comfort during the hot summer months, the architects planted deciduous vines to grow over the pergola. These vines provide shade when needed, cooling the living spaces, but they also allow sunlight to penetrate in winter when the leaves have fallen. This sustainable solution ensures a comfortable and energy-efficient living environment year-round.

Architectural Style and Materiality: A Harmonious Blend

The Maria i el Pablo House stands as a perfect example of contemporary Spanish architecture, blending functional modern design with traditional materials. The renovation retained key structural elements of the original house, such as the load-bearing walls and bay windows, while introducing new materials like thermal clay and hemp to enhance energy efficiency. The thoughtful design incorporates wood, metal, and natural materials that harmonize with the surrounding landscape, ensuring that the house feels connected to its environment.

A Modern Home Renovation Success

The renovation of Maria i el Pablo House demonstrates how modern architecture can respect a home’s origins while transforming it into a sustainable, comfortable space. OBO Estudi’s approach, which balances aesthetics, functionality, and environmental awareness, provides a compelling model for modern home renovation in Spain. Through careful planning and thoughtful design, they have not only enhanced the home’s thermal comfort but have also created a seamless connection between the family and the natural beauty of the Collserola Natural Park.

This project reflects the potential of modern home renovation to create spaces that are both energy-efficient and closely integrated with their surroundings, providing a model for future sustainable home renovations across Spain.
