“Throughout the United States, the housing deficit has created an affordability crisis. The underbuilding of new homes following the recession coupled with restrictive policies has led to historically low housing supply–and the high costs that come with it. To highlight the solutions that will address this crisis, Zillow and the Casita Coalition have assembled a playbook of strategies to “Build the Middle” by expanding affordable, middle-scale housing options.”

Our friends at Zillow & the Casita Coalition have published a useful playbook that highlights innovations in the field of gentle density housing, collating them in an actionable framework template.

Our friends at Happy Cities have crafted a one-of-a-kind toolkit designed to enhance social well-being through thoughtful multi-unit housing designs, supporting diverse individuals of all ages, backgrounds, abilities, household sizes, and incomes. As they describe it:

“Over 2023 and 2024, Happy Cities, Hey Neighbour Collective, and researchers from Simon Fraser University worked together with five local municipalities and one First Nation to co-create new policies to encourage sociable multi-unit housing design.

“Building on the learnings from this project—and nearly a decade of prior research—Happy Cities and Hey Neighbour Collective have published a new design toolkit of evidence-based strategies to nurture social wellbeing multi-unit housing. The design principles and actions equip policy makers, planners, designers, and community members to build and advocate for more socially connected, inclusive communities, drawing on long-term research and engagement with residents and housing industry actors—including non-profit housing providers, city planners, architects, and market developers.

“In the face of growing challenges—including an acute housing affordability crisis, extreme weather, social isolation, and an aging population—our social connections are one of the strongest resources we have to chart a more sustainable, resilient path forward.”

Discover the New Standardized Designs for Gentle Density Homes in B.C.

In September 2024, the Government of British Columbia released a series of free, standardized designs to help facilitate the development of gentle density homes. These designs are versatile, using a “building blocks” approach that allows for customization. You can mix and match elements to add features like garages or additional bedrooms and stack up to three storeys high. The collection includes a range of options from duplexes and triplexes to quadplexes and townhouses, with various roof shapes and exterior finishes to blend seamlessly into existing neighborhoods. There are also designs for accessory dwelling units, like laneway homes, and adaptable cottages perfect for aging in place.

All designs comply with the 2024 B.C. Building Code and can be tailored to fit different lot sizes and site conditions across the province. The design files are available for free download and have been compiled into a convenient catalogue for easy browsing.

These standardized designs are expected to save time and reduce costs for local governments and builders, speeding up approvals and construction. This initiative is a key component of the Homes for People action plan, aimed at unlocking more homes faster by creating favorable conditions for rapid housing development.

Name: Happy Cities

About: Happy Cities is an urban planning, design, and engagement consulting firm with a mission to create happier, healthier, more inclusive communities. As part of its housing practice, Happy Cities advises municipalities, developers, and housing providers on strategies to support resident wellbeing throughout development and after move-in.

The organization’s Happy Homes research shows how intentional design can reduce social isolation, support age-friendly homes, and boost community resilience in multi-unit buildings, culminating in a toolkit to help housing providers turn wellbeing evidence into action. Happy Cities has applied these design strategies to developments like Our Urban Village Cohousing, an innovative missing middle project that offers a promising solution to Vancouver’s housing and social isolation crises. Along with showcasing the many benefits of gentle density, the project identifies solutions to reducing some of the financial and policy barriers that can impede community-oriented housing models.

ReHousing is a pioneering research initiative focused on converting single-family homes into multi-unit housing. Their approach emphasizes affordable, common-sense design to create high-quality, well-designed living spaces. Explore more about their work on their profile page on the Gentle Density Toolbox.

ReHousing leads numerous innovative projects, including a design catalogue featuring cost-effective, gentle density designs. This catalogue offers unique insights into the challenges and opportunities presented by various house configurations and lot sizes.

The designs in this catalogue have been categorized based on the relative cost and complexity of construction. Each design is mindful of future phasing, so you can move from one level to the next without having to redo work that you have already done. Each drawing represents one of the thirteen common house types found throughout Toronto, where ReHousing is based.

The full catalogue can be accessed here.

As Vancouver grows and evolves, we need to ensure that there are housing options that meet the needs of the diverse households that live and work here, including more “missing middle” housing options. With the help of Quickviz, the City of Vancouver developed this useful video that illustrates the changes proposed to allow more of this type housing in low density neighbourhoods across the city as part of the implementation of the Vancouver Plan. The animation depicts a standard block with a variety of housing options, including multiplexes (buildings with up to 6 units on a single lot).


As Vancouver grows and evolves, we need to ensure that there are housing options that meet the needs of the diverse households that live and work here, including more “missing middle” housing. With the help of Uytae Lee from About Here, the City of Vancouver explains what the “missing middle” is, and why they are exploring changes to allow more of this type of housing, including multiplexes (buildings with up to 6 units on a single lot), in low density neighbourhoods across the city as part of the implementation of the Vancouver Plan.

Nestled near the Elders Centre in the Tl’etinqox Community, six cabin-like homes are placed to form a circle to represent the four sacred directions, the cycle of the seasons, the cycle of life and more, and to encourage community gathering.

Tl’etinqox began to develop Elders Cabins in 2019 to honour the intentions, prayers, and needs of their Elders by providing safe and affordable living spaces for them to age in place, at the heart of the community. Elder tenancy applications opened for the cabins in September 2020.
