Modern & Wellness

The traditions on the other pages grew over centuries. The three approaches here are newer and draw on research in psychology, building science and accessibility. They reach many of the same conclusions as older traditions (face the sun, bring nature inside, keep things simple and usable), but they come with measurable benefits.

Origin

Biophilia means "love of living things." The psychologist Erich Fromm used the term in the 1960s, and biologist E. O. Wilson popularized it in his 1984 book Biophilia, arguing that people have an inborn need to connect with nature. Researcher Stephen Kellert later developed biophilic design as a framework for buildings. A frequently cited 1984 study by Roger Ulrich found that surgical patients with a window view of trees had shorter hospital stays than patients facing a brick wall.

Key Concepts

• Visual connection to nature: Views of trees, sky, water and gardens.
• Natural light: Daylight that changes through the day.
• Natural materials: Wood, stone and natural fibers.
• Water: The sight and sound of water.
• Prospect and refuge: Open views paired with sheltered, protected spaces.

Signature Features

Practical Real Estate Considerations

• Views and light: Window placement and outlook strongly affect how a home feels.
• Mature trees: Shade, privacy and views (see tree rules on the Texas page).
• Outdoor living: Patios, porches and gardens visible from main rooms.
• Natural materials: Wood floors and stone surfaces.

Modern AdaptationsBiophilic principles show up in everything from large sliding glass walls to small touches like window-facing kitchen sinks and indoor herb gardens.

Origin

Builders have oriented homes to the sun for thousands of years; many ancient Greek houses opened to the south. Modern passive solar design grew in the United States after the energy crises of the 1970s. It uses a home's orientation, windows, shading and materials to collect, store and distribute the sun's heat in winter and to block it in summer, without mechanical systems.

Key Concepts

• Orientation: In the Northern Hemisphere, place the main living areas and most windows facing south.
• Shading: Size roof overhangs to block high summer sun while letting low winter sun in.
• Thermal mass: Tile, concrete or masonry absorbs heat and releases it slowly.
• Natural ventilation: Operable windows placed to move air through the home.
• Insulation and air sealing: Keep heat where you want it.

Signature Features

South-facing windows

With properly sized overhangs above them.

Deep roof overhangs and porches

Shade in summer.

Limited west-facing glass

Reduces hot afternoon sun.

Tile or concrete floors

Thermal mass in sunny rooms.

Clerestory windows

Daylight and heat release high in the room.

Light-colored or reflective roofs

Reduce heat gain.

Shade trees

Deciduous trees on the south and west.

Practical Real Estate Considerations

• Orientation in Texas: In hot climates, shading and limiting west-facing glass matter more than collecting winter heat. Look at which way the main windows face and how they're shaded.
• Energy ratings: Ask about a HERS Index score, insulation levels and window specifications.
• Utility history: Ask for 12 months of utility bills.
• Lot orientation: On new construction, the lot's orientation affects long-term comfort and cost.

Modern AdaptationsNet-zero and solar-ready homes combine passive design with high insulation and rooftop solar panels.

Origin

Architect Ronald Mace, who used a wheelchair himself, coined the term universal design: design that is usable by as many people as possible, of all ages and abilities, without special adaptation. He founded the Center for Universal Design at North Carolina State University, where a working group published the Seven Principles of Universal Design in 1997.

Key Concepts: the Seven Principles

1. Equitable use: Useful to people with diverse abilities.
2. Flexibility in use: Accommodates a range of preferences and abilities.
3. Simple and intuitive use: Easy to understand.
4. Perceptible information: Communicates clearly to all users.
5. Tolerance for error: Minimizes hazards and accidents.
6. Low physical effort: Comfortable, with minimal fatigue.
7. Size and space for approach and use: Room to reach, move and use.

Signature Features

Step-free entry

At least one entrance without steps.

Wide doors and halls

Easy passage for strollers, carts and wheelchairs.

Lever handles

Easier than knobs for everyone.

Curbless showers

With reinforced walls for future grab bars.

Main-floor bedroom and full bath

Single-level living when needed.

Reachable controls

Light switches, outlets and thermostats at comfortable heights.

Varied counter heights

For sitting or standing work.

Practical Real Estate Considerations

• Single-level living: A main-floor bedroom and bath add long-term flexibility.
• Entries: Step-free or easily ramped entrances.
• Bathrooms: Curbless showers and blocking for grab bars.
• Future-proofing: Wider doors and halls are much easier to build in than to retrofit.
• Describe features, not people: Listings should describe accessible features, not who the home is "for."

Modern AdaptationsUniversal design features are increasingly standard in new construction and in remodels planned for aging in place.
