Constructed from cross-laminated timber, this urban housing solution integrates rainwater harvesting and load-sharing between neighboring properties, providing a flexible and sustainable living environment.
5 key facts about this project
01
Constructed using cross-laminated timber for enhanced structural efficiency.
02
Features a flexible layout accommodating one to three bedroom configurations.
03
Incorporates rainwater harvesting systems for efficient water management.
04
Utilizes telescopic feet to eliminate the need for traditional foundations.
05
Designed to share structural loads between neighboring properties.

The Bird is designed to address the need for affordable housing in Toronto. Positioned between two properties, it allows neighbors to share the structural load. This thoughtful design not only makes efficient use of land but also encourages community involvement. The prefabricated structure offers a practical solution for urban living while maintaining a connection to the city’s diverse landscape.

Design Concept

The layout of the Bird can accommodate various configurations, featuring options for one to three bedrooms. The building’s height and profile align with the sloped roofs of nearby homes, which helps it blend into the surrounding area. This design choice allows for easy access to garages and driveways beneath the structure, ensuring that residents can move easily in and out of their homes while enjoying their outdoor spaces.

Material Choices

Cross-laminated timber panels serve as the main materials used in the construction of the Bird. These panels simplify the building process and contribute to energy efficiency. They provide good insulation while also having the benefit of sequestering carbon. Their lightweight nature allows the Bird to be built relatively quickly and at a lower cost.

Sustainability Features

Sustainability plays a key role in the Bird's design. Rainwater is harvested through integrated eaves, providing water for low-flow toilets and a garden that helps improve indoor air quality. The design takes advantage of natural light, allowing sunlight to enter in the winter while providing shade in the summer. The thermal mass of the service core absorbs heat during the day and gives it back at night, helping to reduce energy needs.

Operational Efficiency

The Bird is manufactured off-site, allowing it to be assembled quickly on location. This approach minimizes disruption in the neighborhood and speeds up construction. The building rests on wide, load-dispersing telescopic feet, which eliminates the need for traditional foundations. This means it can fit into narrow urban spaces that might not be suitable for standard construction methods.

The Bird includes features that promote neighborly interaction, such as retractable stairs that provide access to shared spaces. These elements enhance both privacy and community connections, creating a unique living environment in the heart of the city.

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.
