## Project Overview

Located in Portugal, the design features a guest house combined with an olive oil production facility, drawing on the principles of permaculture. The intent is to create a sustainable environment that emphasizes the relationship between architecture, agricultural practices, and community involvement. The project seeks to enhance regional identity while promoting an eco-conscious lifestyle through thoughtful spatial organization and responsible design.

### Design Strategy

The architecture utilizes a simple, low-profile approach that harmonizes with the surrounding landscape. Extensive use of natural materials, including local spruce, oak, clay bricks, and zinc panels, not only reflects the regional character but also supports longevity and energy efficiency. The integration of ample glazing promotes visual connectivity to the landscape, facilitating natural ventilation and minimizing reliance on mechanical systems. The layout encourages communal living, with spaces designed to foster interaction, such as an olive oil tasting room featuring a large wooden table for social engagement.

### Functional Zones and User Experience

The guest house comprises three distinct levels: a basement dedicated to olive oil storage, a ground floor that houses kitchen and communal areas, and a second floor for private accommodations. The arrangement of these spaces enhances accessibility and flow, promoting social interaction among guests. Specific areas, such as the meditation and prayer space, are designed to provide tranquility through strategic placement of windows that filter natural light. The attention to climate-responsive design is notable, as features like louvers and thermal mass elements contribute to natural heating and cooling, aligning with the project's commitment to sustainability.

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.
