Universal Design and Adaptable Housing Models

This section discusses, how housing can be made adaptable to accommodate occupants’ changing requirements using the principles of universal design.

It is estimated that by the year 2036, more than half of all Canadian households will be headed by people 55 years or older¹. As the needs of homeowners change, they are demanding more versatility from their housing. Housing with flexible features that can accommodate occupants’ changing requirements easily and inexpensively will be in high demand.

The key to meeting this demand is to make housing as adaptable as possible from the time of construction. An adaptable housing unit can be a standard-looking unit with features that can be tailored to the specific needs of residents as their particular needs evolve, without costly renovations or structural changes. Accessible features like wider doors and corridors, entrances without steps and lever hardware should be part of the unit from the outset. Wall reinforcement allows for the later installation of grab bars or rails; these are less expensive if incorporated during initial construction. Cabinets can be designed to be height-adjustable or removable.

Adaptable housing addresses some of the same concerns as universal design, while catering to an even wider range of needs. Adaptable housing can be upgraded, expanded, divided into extra units or used for a variety of purposes throughout its life. Several models have emerged that demonstrate the opportunities and benefits of adaptable housing.

Adaptability is also very relevant at the neighbourhood scale. A community that offers a range of housing forms (detached homes, row houses, apartments, and others) and of tenure options allows residents to choose different dwelling types and tenure arrangements as their needs change without having to relocate to other neighbourhoods. Housing developments that offer a continuum of care, ranging from self-contained units for independent living, to housing with a higher level of support, to a full-care housing arrangement, enable residents to make these transitions without moving away.

FLEXHOUSING

FlexHousing™ incorporates, at the design and construction stage, the option to make future changes easily and with minimum expense in order to meet the evolving needs of its occupants. This approach allows families and individuals to access more affordable housing, stay in the home longer and can help make these units more affordable for owners and renters.

As circumstances change, FlexHousing™ allows homeowners to adapt their existing housing relatively easily and economically rather than move. For instance, if a resident becomes less mobile and requires a bathroom on the main floor of the house, the design of the plumbing system will allow the owner to convert a closet or spare room into one. Similarly, the design of the stairs will allow for the installation of a stairclimbing mechanism. The inclusion of unfinished spaces within a new home to reduce first costs provides an option for finishing at a later time as needs demand. FlexHousing™ also emphasises flexibility of tenure. A young family may need all floors of a house as children grow up but once they move out, the home should be easily subdividable to accommodate an income producing secondary suite (see “Grow Home” below).

Any home can be a FlexHouse — a suburban bungalow, high-rise condominium or infill townhouse. FlexHousing™ is simply an approach to designing and building homes based on the principles of adaptability, accessibility, affordability and Healthy Housing™.

Adaptability means thinking ahead during the construction of the house. This saves time, money and hassle later on by avoiding the need for costly renovations, for example roughing in plumbing to accommodate future needs for bathroom conversions, or providing an unfinished space in a new home that can be converted later.
Accessibility means creating a home that is user-friendly to people of all ages and abilities. For example, wide doors and stairs, low windows, and easy-to-grasp lever handles benefit children and the elderly alike.
Affordability may mean investing money up front in order to save in the future. While the up-front costs of an adaptable house may be greater compared with a normal home, homeowners benefit from the investment in the long term. For example, structural reinforcement of walls allows for the future addition of grab bars and other support features at a reasonable cost.²

Richmond, B.C., is home to a two-storey demonstration FlexHouse built to accommodate a variety of homebuyers. It has a floor plan that enables the house to be converted from a four-bedroom family home to a duplex or a set of rental suites. The house was also designed using healthy materials and with energy efficiency and accessibility in mind. The Richmond FlexHouse Project is the result of a collaboration between CMHC, the City of Richmond and Pacific Western Developments Ltd., which built the house.³

Also in British Columbia, the City of Saanich has instituted a Basic Adaptable Housing bylaw that requires basic adaptable housing features in all newly constructed buildings that are serviced by an elevator and contain apartment or congregate housing uses.⁴
