## Overview and Context

The Vigaria Home is located within Sintra Natural Park, Portugal, approximately 50 meters above sea level. The site’s unique geographical features, including a backdrop of pine trees and ocean views, inform its architectural design, which prioritizes ecological sensitivity and contemporary aesthetics. The home integrates locally sourced Vigaria marble, reflecting both regional materiality and heritage.

### Spatial Organization and User Experience

The design promotes a comfortable living environment by optimizing natural light and airflow. A large window connects the interior to the surrounding landscape, offering expansive views. The spatial arrangement creates distinct zones that facilitate both social interaction and privacy. Key features include a spacious living room that opens onto an outdoor terrace, a tranquil bedroom designed for privacy with limited window openings, and a bathroom that maximizes natural light while incorporating environmentally friendly products. The floor plan encourages fluid movement throughout the home, enhancing the overall user experience.

### Material Selection and Sustainability

The material palette underscores a commitment to sustainability and durability. The use of Vigaria marble, coupled with 8 cm thick marble bricks, establishes a robust façade while maintaining aesthetic cohesion. The timber frame, treated with eco-friendly coatings, enhances indoor air quality. Sustainable practices are further implemented through the use of Kingspan Kooltherm K-15 insulation, which improves thermal performance, and a Slimline Water Tank designed for rainwater recycling. Additional features, such as natural ventilation openings and a biodiversity pond, support local ecosystems and reduce reliance on municipal water supplies. These elements collectively signify a forward-thinking approach to residential architecture with an emphasis on minimal environmental impact.

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.
