# Why custom-home design is changing Home sales are falling overall. For custom builders that means their inventory will sit unless designs match what buyers want. National Association of Home Builders data and builders' market behavior show the shift is toward homes that are smaller but better organized and built to a higher standard.
The wide-open "great room" is losing status as the default layout. Buyers and builders cite practical downsides: higher heating and cooling costs, noise and odor control, reduced privacy, and spaces that feel cluttered. Instead, current designs favor semi-open or traditional plans that create separation while keeping natural light and sight lines.
- Partial or temporary walls, pocket doors, and open bookcases that define zones without closing them off.
- Flooring transitions (tile in the kitchen, hardwood in the living area) used to signal different functions.
- Strategic lighting to create distinct atmospheres within a shared footprint.
Multifunctional rooms plus dedicated spaces
The goal is efficient use of square footage so each area can adapt as needs change without feeling crowded.
Designing for multigenerational households
Demographic shifts are increasing demand for multigenerational-ready homes. That demand shows up in requests for single-story plans or two-story layouts with primary suites on the main floor. Common, practical features now requested include:
- Zero-step entries and wider hallways for mobility.
- Curbless showers and accessible bathroom layouts.
- Flexible bedroom arrangements that can host aging parents or adult children.
These features make a home usable for more people over a longer lifecycle, reducing the need for later retrofit work.
Indoor-outdoor integration and wellness spaces
Buyers increasingly treat yards and covered outdoor rooms as extensions of living space. Popular features are covered patios, outdoor kitchens, screened porches, and multislide patio doors that blur the line between inside and outside. Landscape design uses movable or low structures—planters, trellises, low hedges—to create distinct outdoor zones that can be rearranged.
Market context: Grand View Research projects the global outdoor living structure market will reach $4 billion by 2033, evidence of growing demand for outdoor-living investments.
Wellness-focused design is also rising. The 2026 Houzz Emerging Summer Trends Report shows interest in wellness rooms and biophilic elements—design choices that bring natural materials, daylight and plant life into the home.
