### Overview
Hora de Ouro is situated in Barreira, Portugal, and serves as a dedicated space for the cultivation and tasting of olive oil. The design is attentive to the region's natural topography and integrates contemporary aesthetics with functional requirements. This project aims to create an environment that reflects the cultural heritage of olive oil production while fostering sensory engagement with the associated experiences.

### Spatial Configuration
The layout of Hora de Ouro features distinct areas designed to enhance user interaction while accommodating various activities. At the core of the design is a central courtyard that facilitates movement and encourages communal gatherings. The incorporation of large, rounded openings throughout the structure allows natural light to permeate interior spaces, enhancing visual connectivity with the surrounding landscape. Additionally, the arrangement of private and communal spaces strikes a balance between providing privacy for individuals and encouraging social interaction among guests.

### Materiality
Material selections for Hora de Ouro prioritize sustainability and local relevance. The use of limestone lends a rustic aesthetic while ensuring structural durability. Oak wood is utilized in cabinetry and furniture to promote local craftsmanship, while cork, olive tree wood, and terracotta contribute to ecological friendliness and aesthetic warmth. Recycled bottle glass tiles introduce an artistic element that emphasizes innovation in sustainability. The integration of natural fibers and eco-friendly insulation further optimizes the building’s interior climate, aligning with local building practices and environmental considerations.

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.
