A Blend of Functionality and Aesthetics

Nestled in the charming town of Inca, Mallorca, the 54 HPP Inca project is a testament to modern, sustainable residential architecture. This innovative development, completed in 2023 by the talented team at Fortuny-Alventosa, Morell Arquitectes (F-AM Arquitectes), showcases 54 social protection homes designed with a keen eye on urban integration and environmental harmony. The project covers a substantial 4,633.60 square meters above ground, with an additional 1,746.90 square meters dedicated to parking space in the basement.

Smart Design for Urban Integration

The architectural brilliance of the 54 HPP Inca project lies in its thoughtful urban integration. The building is strategically positioned along a north-south axis, splitting into two independent volumes that create a welcoming public space between them. This design not only enhances the aesthetic appeal but also fosters a sense of community among residents.

Each housing module is meticulously organized around a central wet core, distinguishing between day and night areas. This thoughtful layout maximizes functionality while ensuring the comfort and convenience of residents. The structure employs a reticular system of concrete slabs with large spans, supported by metal pillars. This approach not only speeds up construction but also provides flexibility for future modifications.

Embracing Sustainable Architecture

Sustainability is at the heart of the 54 HPP Inca project. The homes are designed with cross ventilation and feature outdoor spaces, including private gardens on the ground floor and terraces and patios on the upper levels. These elements utilize passive strategies to regulate excess summer heat, ensuring a comfortable living environment year-round.

The project boasts impressive energy efficiency with Near Zero Energy Building (NeZB) standards, achieving a remarkable efficiency rate of 0.64 kWh/m² per year. Water usage is optimized at a maximum of 100 liters per person per day, and waste production is reduced by 20%. Additionally, the project achieves a 50% reduction in CO2 emissions from materials compared to similar buildings, highlighting its commitment to sustainability.

Innovative Materials and Techniques

The materials and construction techniques used in the 54 HPP Inca project further underscore its commitment to sustainability and innovation. The façade is composed of a double ceramic sheet with recycled cotton insulation, coupled with exterior insulation made from projected cork and lime. These materials, developed by local companies, ensure excellent thermal performance and environmental sustainability.

Solar protections crafted from FSC-certified larch wood, manufactured by local artisans, add a touch of traditional craftsmanship to the modern design. The Aerothermal system, a standout feature, provides highly efficient ACS (hot water) with minimal energy consumption. Furthermore, the homes are equipped with heat recovery ventilation systems that temper the air using community Aerothermal systems, enhancing overall energy efficiency.

A Collaborative Effort

The success of the 54 HPP Inca project is a result of a collaborative effort involving various experts. Joan J Fortuny Giró and Alventosa Morell Arquitectes led the architectural vision, while engineers from Estudi d’Enginyeria de les Illes Balears and technical architects Marco Menéndez and Jaime Oliver ensured the structural integrity and functionality of the project. Additional contributions from Marina Morey, Gori Llambias, Sandra Vargas, Juan Fortuny, Joan Mas, and Lluís Guasp further enriched the project’s development.


The 54 HPP Inca project is a shining example of how modern architecture can blend seamlessly with sustainability and functionality. By prioritizing urban integration, innovative design, and environmental responsibility, Fortuny-Alventosa, Morell Arquitectes have created a residential space that not only meets the needs of its inhabitants but also contributes positively to the broader community and environment. This project stands as a model for future developments, showcasing the potential of thoughtful, sustainable architecture in shaping our living spaces.
