**Project Overview**

Ca' du Má, or "House of the Sea," serves as a senior housing complex in Voltri, a coastal area in Genoa, Italy. The project is designed to improve the quality of life for its residents through a focus on community engagement, natural connectivity, and sustainable architecture. Positioned along the Ligurian coast, the design integrates living spaces with the surrounding marine environment.

**Layout and Modular Design**

The architectural layout employs a modular configuration tailored to the specific needs of elderly residents. The arrangement consists of two types of living modules: a 48-square-meter unit accommodating up to two individuals and a 36-square-meter unit designed for single occupancy. These modules are strategically oriented to maintain privacy while still offering communal areas, such as gardens and walking trails, that foster social interaction. Interconnected by open spaces and covered zones, these elements promote resident engagement while providing shelter from the elements.

**Sustainable and Material Choices**

The construction prioritizes sustainability through the use of prefabricated structures, which streamline assembly and reduce construction waste. The buildings feature insulated walls and roofs for thermal and acoustic comfort, while sunshade structures are incorporated to enhance energy efficiency. Photovoltaic panels are installed to harness solar energy, supporting the project’s commitment to renewable energy sources. Additionally, communal areas are designed to encourage a sense of community, offering spaces for creative workshops, fitness programs, and wellness activities, all aimed at enhancing residents' mental and physical well-being.

The integration of outdoor pathways, lined with greenery and communal gardens, creates tranquil spaces that extend the living environment and encourage connection with nature. This landscape-oriented design approach not only provides scenic views but also facilitates easy access to outdoor activities, enhancing the overall resident experience.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
