How to Design a Custom Home That Ages With You

Building a custom home offers the perfect opportunity to incorporate features that support comfortable living throughout all life stages. Universal design principles create spaces that work for everyone, from young children to aging adults.

Main Floor Primary Suite

Perhaps the most important aging-in-place feature is a main floor primary bedroom suite. While two-story homes remain popular, stairs become increasingly challenging with age or temporary mobility limitations from injuries or surgeries.

A complete main floor suite includes the bedroom, full bathroom, and ideally a walk-in closet. This arrangement allows homeowners to live comfortably on one level if stairs become difficult, without sacrificing privacy or convenience.

Wider Doorways and Hallways

Standard 30-inch doorways accommodate most people but create challenges for wheelchairs, walkers, or anyone with mobility aids. Upgrading to 36-inch doors throughout your home costs little during construction but provides significant long-term benefits.

Similarly, wider hallways (42-48 inches instead of the standard 36 inches) improve accessibility and simply feel more spacious and luxurious.

Zero-Step Entries

At least one entrance to your home should be at grade level without steps. This benefits not just wheelchair users but anyone moving furniture, using strollers, or dealing with temporary mobility limitations.

If your site requires elevation changes, plan for a gentle ramp or sloped walkway that blends naturally with your landscaping.

Bathroom Considerations

Design bathrooms with reinforced walls around toilets, tubs, and showers to support future grab bar installation. Installing grab bars during construction looks institutional, but reinforcing walls allows you to add them later if needed.

Curbless showers with linear drains eliminate tripping hazards and accommodate wheelchairs if necessary. They also create a sleek, modern aesthetic that appeals to all ages.

Lever Hardware and Rocker Switches

Replace round doorknobs with lever handles and traditional toggle switches with rocker switches. These simple changes benefit anyone with arthritis, full hands, or limited dexterity.

Lighting and Contrast

As we age, we need more light to see clearly. Plan for abundant natural light supplemented by layered artificial lighting. Include task lighting in work areas, ambient lighting for general illumination, and accent lighting for safety.

Use contrasting colors between floors, walls, and trim to help define spaces and prevent trips and falls.

Single-Level Living Potential

Even if you build a two-story home, design the main level to function independently. Include a full bathroom, laundry facilities, and adequate living space on the main floor.

Future-Proofing Your Investment

These universal design features don't just support aging in place—they increase your home's appeal to a broader range of buyers if you eventually sell. Accessibility features have moved from specialized accommodations to desirable amenities that everyone appreciates.
