Alcove House is a compact residential design that prioritizes efficiency and sustainability. Located in an area that promotes small living spaces, the house covers only 25 m² and organizes its essential functions around a central fireplace. Drawing inspiration from a snail shell, the layout optimizes every corner, ensuring that comfort and usability co-exist within a limited footprint.

Design Concept

Inside Alcove House, four distinct areas are set around the central hearth: the kitchen, dining room, bedroom, and bathroom. This arrangement encourages a sense of togetherness while still allowing for privacy in each space. Each area is flooded with natural light through square windows placed within thoughtfully designed niches, creating a warm and welcoming environment.

Material Selection

Cedar wood has been chosen for the walls, ceiling, and floor. This choice adds warmth and helps with insulation. The fireplace features Moroccan Zellige tiles, which add visual interest and connect the design to local craftsmanship. Together, these materials support the overall aim of sustainability while enhancing the living experience.

Construction Methodology

The structure uses a wooden framework, making it lightweight and sturdy. The roof is designed in two layers, covered with shingles and solar cells, promoting energy efficiency. The design incorporates biological sewage treatment along with physical microfiltration to manage water responsibly. These features reflect a strong commitment to environmental considerations.

Technical Features

Solar energy is harnessed through solar cells placed on the southwest and southeast sides of the roof and walls, allowing for an independent power supply. Heating comes from the fireplace as well as an underfloor heating system that optimizes heat usage. The walls are thick enough to accommodate both water heaters and batteries, providing practical energy solutions. Additionally, discreet sun blinds within the windows help prevent overheating, ensuring comfort for the occupants.

Alcove House exemplifies modern living by successfully combining practical design and environmental awareness within a compact space, offering a balanced approach to everyday life.

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.
