## 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.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
