Elevated Green Roofs and Fiber Cement Structures in Sustainable Urban Housing

Project in-detail

Suspended units supported by modular platforms and enhanced by green roofs redefine underutilized urban spaces in Vancouver, providing affordable housing that integrates functionality with community-oriented design.
5 key facts about this project
01
Suspended housing units create unimpeded vehicle access beneath.
02
Green roofs serve as urban pathways for enhanced connectivity.
03
Community spaces incorporate retail and playground areas.
04
Modularity allows flexible unit configurations for diverse needs.
05
Fiber cement tiles provide durability in high-traffic areas.

Located in Vancouver, the design addresses the urgent need for affordable housing in the city, which faces challenges due to its growing population and housing demand. The project reimagines underused urban spaces, especially those adjacent to major transport infrastructure such as bridges and SkyTrains. The overall concept seeks to create a community that is accessible, functional, and sustainable, integrating living spaces with the urban environment.

Modular Design Approach

The design employs a modular approach that utilizes suspended platforms to elevate housing units. This strategy maximizes land use by pushing living spaces upward, allowing vehicles to move freely below. It not only addresses space constraints but also accommodates changing living needs. This flexible design can adapt over time as community requirements evolve.

Integration of Green Spaces

Green roofs are a notable aspect of the project. They enhance both the beauty and functionality of the housing units, serving as green pathways for train passengers. This element contributes positively to the city’s ecology, encouraging biodiversity and enhancing the environment. The careful combination of nature with built structures emphasizes the importance of greenery in urban areas.

Community-Centric Elements

The design goes beyond providing simple living spaces. It includes communal areas that promote social interaction among residents. By incorporating shops and playgrounds in the redesigned spaces beneath the bridge, the project enhances community engagement and activates the area. The focus on communal facilities reflects a commitment to serve not only the residents but the wider neighborhood.

Materials and Construction Techniques

Selected materials for the units include wooden floors, fiber cement tiles, and steel. Each material was chosen for its durability and suitability for urban settings. Wooden floors add warmth, while fiber cement tiles are practical for high-traffic areas. Steel offers structural strength, ensuring stability for the elevated units and balancing the overall design.

In this design, the concept of sustainable urban living takes form through thoughtful planning and execution. The integration of functional details and communal spaces creates a model for modern urban environments that can adapt to the needs of their inhabitants.

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.
