### 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.

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.
