DESIGNING FOR A HOUSEHOLD UNLIKE THE ONE WE TRAINED FOR

For most of the twentieth century, residential design assumed a mother at home, a father commuting, children developing along a predictable curve, and grandparents eventually moving to a facility. Those assumptions shaped kitchens, hallways, bedrooms, and stairs. Almost none of them hold today. The biggest opportunity in residential design is catching up to who is actually living in the house.

Fathers now make up close to one in five stay-at-home parents, while about 74% of mothers with children under 18 are working. The emerging reality is that no one is reliably home—or whoever is home is also working or caregiving. Homes need sightlines that support supervision, flexible rooms that shift between nursery, office, and guest use, and parallel storage and drop zones for shared family logistics.

CDC surveillance now puts autism prevalence among 8-year-olds at 1 in 31, not counting the broader population of children with ADHD, sensory-processing differences, or other needs. Sensory load is a design variable: avoid flicker and harsh contrast, control acoustics, create predictable circulation, provide quiet low-stimulation spaces, reduce visual clutter, and favor adaptable elements over fixed functions. Sensory-conscious design is usually better design for everyone.

By the mid-2030s, the United States will have more people over 65 than under 18. Roughly three-quarters of adults 50 and older want to remain in their homes, yet only about half are confident their home and community can support them. Zero-step entries, wider doors, lever hardware, grab-bar blocking, curbless-shower rough-ins, and first-floor rooms that can become bedrooms cost little when planned early and much more after a crisis.

Accessory dwelling units, in-law suites, and homes that comfortably hold three generations are increasingly common requests, driven by childcare, eldercare, or both. “Visitable” and adaptable design should be the default—even for clients who are not yet thinking about aging—because a home’s occupants and caregiving roles will change repeatedly over its life.

Today’s household is more variable, over a longer horizon, than the one our design conventions were built around. The professional response is a design posture: build in flexibility, plan for change, and treat accessibility, sensory consideration, and adaptability as baseline good design—not special accommodations added later. Families may never ask for that posture by name; they simply notice, years later, that the house still works.

The Mistake: Failing to provide adequate clearance for wheelchairs, walkers, or mobility aids.
The Fix: Ensure doorways are at least 32 inches wide and hallways are 36 inches or more. Wider is better for comfort and maneuverability.

The Mistake: Using raised thresholds that create tripping hazards or block wheelchair access.
The Fix: Opt for flush, zero-threshold transitions at entrances and between rooms, especially in bathrooms and outdoor access points.

The Mistake: Inadequate or overly harsh lighting that causes shadows or glare, making navigation difficult.
The Fix: Layer natural and artificial lighting with dimmable fixtures and low-glare finishes. Consider motion-sensor lighting for hallways.

The Mistake: Placing switches, outlets, cabinets, and appliances out of comfortable reach.
The Fix: Mount light switches no higher than 48 inches and outlets at least 15 inches above the floor. Use pull-down shelving in kitchens and closets.

The Mistake: Not providing enough open space for wheelchairs or mobility devices to turn.
The Fix: Leave a 60-inch diameter clear floor space in key areas like kitchens, bathrooms, and entryways.

The Mistake: Using slippery materials or rugs that can cause trips or falls.
The Fix: Choose slip-resistant flooring and secure rugs with non-slip pads. Avoid thick pile carpets that make wheelchair rolling difficult.

The Mistake: Storing frequently used items in high cabinets or deep shelves.
The Fix: Place essential storage between 15 and 48 inches from the floor for easy reach whether standing or seated.

The Mistake: Choosing colors and finishes that blend together, making it hard for people with low vision to navigate.
The Fix: Use contrasting colors between floors, walls, and furniture edges. Highlight door frames, countertops, and step edges for clarity.

The Mistake: Installing fixtures and layouts that are difficult for people with mobility or balance challenges.
The Fix: Include grab bars, roll-under sinks, and enough floor space for a wheelchair to turn. Install shower seats where possible.

The Mistake: Trying to “add” accessibility features at the end of a project, resulting in awkward or unattractive solutions.
The Fix: Integrate accessibility from the start of the design process. This ensures a cohesive, beautiful, and functional space that doesn’t feel clinical.

When accessibility is done right, it’s not noticeable—it’s simply part of the design. By avoiding these common mistakes, you can create spaces that are inclusive, safe, and beautiful for everyone.
