### Project Overview

Located in the Serra d’Aire e Candeeiros region of central Portugal, the Olive Guest House is a modern architectural project designed to resonate with the local agricultural context. Rooted in the traditions of the Verde family, known for their olive oil production, the guesthouse provides a serene environment that fosters a connection to both nature and local culture. The intent is to create a retreat that reflects traditional values while offering contemporary comforts.

### Spatial Configuration and Functionality

The guesthouse's design revolves around a square layout that optimizes spatial efficiency and enhances the relationship between indoor and outdoor areas. A central courtyard featuring an olive tree serves as the focal point, providing natural light and ventilation while creating a tranquil area for reflection. The ground floor accommodates a large living area, dining space, and tasting room that encourage social interaction, alongside large glass doors that facilitate transitions to outdoor spaces.

Guest rooms prioritize privacy and comfort, each equipped with expansive windows for scenic views and natural illumination. Additionally, the basement includes essential amenities such as an olive oil cellar, a meditation room, and multi-purpose event spaces that enrich the visitor experience. The flexible design of the courtyard supports both communal gatherings and quiet, contemplative moments.

### Material Selection and Sustainability

The Olive Guest House employs a carefully chosen palette of materials that harmonize with the surrounding landscape while ensuring durability. Reinforced concrete provides structural stability, while wood and stone enhance the warmth and rustic aesthetic of the interiors and exteriors. Extensive glass features optimize natural lighting and visually integrate the interior with the outdoors.

The strategic use of materials reflects a commitment to sustainability, contributing to energy efficiency and low maintenance requirements. Overall, the design articulates a focus on environmental harmony, reinforcing the guesthouse's role as a sustainable contributor to the local community and agricultural heritage.

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.
