Barrier-free housing is a home where people of all ages, from babies to older adults, can live safely, securely, and comfortably. This guide explains the design points to consider for each room and fixture with future caregiving needs in mind.

What is barrier-free housing?

Barrier-free housing is housing designed so that everyone can live with peace of mind regardless of age or physical condition. It is a concept close to universal design, but barrier-free is used mainly in the context of homes.

What are the basic points of barrier-free housing?

  • Eliminate level differences:This reduces the risk of falls and makes wheelchair movement easier
  • Eliminate temperature differences:Helps prevent heat shock. Temperature gaps between rooms can increase the risk of stroke and heart attack
  • Prevent falls:Install handrails in hallways, staircases, bathrooms, and similar areas
  • A single-floor layout:Place the living room, water areas, and bedroom together on the first floor

What are the key barrier-free points for each room?

Entryway and hallway

Remove level differences and install a ramp. Hallways should be wide enough for wheelchair access, and handrails should also be installed.

Living and dining area

This is a place where many fall accidents occur. Remove level differences and choose slip-resistant flooring materials.

Kitchen

A height-adjustable kitchen that can be used while seated is recommended. Dish cabinets should be installed at a height that is not too high.

Bathroom and washbasin

Provide handrails on the walls and inside the bathtub, and use slip-resistant flooring materials. At the washbasin, make sure to secure enough space (1,500mm) for turning even in a wheelchair.

Toilet

By reducing the distance between the bedroom and the toilet, you can lessen the burden of moving at night and also help prevent heat shock.

Doors and lighting

Use sliding doors, and place light switches where they can be easily pressed even from a wheelchair. Motion-sensor lighting is also effective.

FAQ

Q. Does barrier-free housing have to be a newly built home?

Existing homes can also be made barrier-free through renovation. However, if it is planned at the time of new construction, costs can be kept lower.

Q. Are there subsidies for barrier-free renovations?

There are programs such as home modification benefits under the long-term care insurance system, as well as subsidy programs provided by local governments.

Q. Should younger households also consider barrier-free housing?

Yes. It offers the advantage of adapting to future lifestyle changes while helping reduce future renovation costs.
