Cross-Laminated Timber Structure With Integrated Rainwater Harvesting in Urban Setting

Project in-detail

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.

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
