## Project Overview

The Vilarejo initiative is situated in Portugal, where it aims to cultivate a sense of community and belonging through an inclusive living environment. This project integrates traditional Portuguese architectural elements with contemporary design principles, prioritizing sustainability and occupant comfort. By fostering connections among residents and enhancing their interaction with the surrounding landscape, Vilarejo seeks to create an inviting atmosphere that supports daily life.

## Spatial Strategy

The design organizes individual dwelling units within a principal "building block," which serves as the core of the settlement. Each unit is configured around communal courtyards, promoting natural movement and interaction among residents. The modular approach allows for flexibility within living arrangements, accommodating diverse family structures and lifestyles while ensuring access to natural light and essential services. Central courtyards are designed as shared spaces for social engagement, featuring amenities such as cafes and libraries to bolster community identity.

## Material Use and Sustainability

Vilarejo places a strong emphasis on material selection, incorporating a mix of traditional and modern resources to align with local heritage and contemporary demands. Notable materials include prefabricated solid timber frames for structural support, flax insulation for enhanced thermal performance, and durable linoleum flooring for ease of maintenance. The use of compressed earth blocks adds to both the structure and aesthetic appeal, while breathable membranes facilitate air circulation and moisture management. The exterior is topped with traditional ceramic tile roofs, reflecting the regional architectural vernacular. Additionally, the project incorporates sustainable technologies that minimize energy consumption and optimize environmental performance, thus addressing the specific heating and cooling needs of the local climate.

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.
