You’ve probably seen them everywhere lately. Those long, low-slung profiles cutting through new suburban developments or tucked into quiet wooded lots. Honestly, for a long time, single story house design was kind of considered "grandma’s house." It was the 1950s rambler with the cramped kitchen and the pink tiled bathroom. But things have changed. Drastically.
The stigma is dead.

Today, some of the most expensive custom builds in the country are strictly one level. Architects like Tom Kundig have shown that luxury isn't about how many stairs you can climb, but how you interact with the land. People are realizing that living on one floor isn't just about aging in place—though that’s a huge perk—it's about a specific kind of flow that multi-story homes just can't replicate.
The flow state of single story house design
When you remove the staircase, you reclaim a massive amount of square footage. Think about it. A standard staircase eats up about 80 to 100 square feet per floor. That’s a walk-in closet or a decent-sized pantry you’re just giving away to transit space.
In a well-executed single story house design, the "great room" isn't just a buzzword. It’s the literal heart of the home. Because you don’t have load-bearing walls supporting a heavy second floor, you can go wide. Really wide. We’re talking massive vaulted ceilings and floor-to-ceiling glass that makes the backyard feel like your living room.
It’s about volume.
A 2,000-square-foot ranch often feels significantly larger than a 2,200-square-foot two-story colonial. Why? Because your sightlines aren't blocked by floor joists or HVAC chases running between levels. You get those "long views" from the front door all the way to the back terrace.
Open layouts vs. the "broken plan"
There’s a common misconception that one-level living has to be one giant, echoing hall. That’s actually a mistake. Modern designers are moving toward what they call the "broken plan."
- You use double-sided fireplaces to signal a transition.
- Maybe a change in flooring from polished concrete to warm white oak.
- Varying ceiling heights—dropping the ceiling in a dining nook to make it feel intimate, then soaring back up in the lounge.
Basically, you get the benefits of an open feel without feeling like you’re living in a gymnasium.
Privacy is the biggest hurdle (and how to fix it)
If everyone is on one floor, how do you escape the noise? This is where most builders fail. They put all the bedrooms in one wing, separated by a thin wall. If your teenager is blasting music at 11 PM, you’re going to hear it.
The "split-wing" layout is the gold standard here.
In this setup, the primary suite lives on one side of the house, while the guest rooms or kids' rooms are on the opposite end. The kitchen and living area act as a massive acoustic buffer. It’s genius. You can host a dinner party in the center of the house while someone sleeps undisturbed thirty feet away.

Another trick? Zoned HVAC. Since heat rises, two-story homes are notorious for being freezing downstairs and sweltering upstairs. A single-story layout is naturally more thermally stable, but you still want separate thermostats for the sleeping and living wings. It saves a fortune on utilities.
What most people get wrong about construction costs
Here is a reality check: building a single-story home is usually more expensive per square foot than a two-story home.
I know, it sounds counterintuitive. But think about the physics. A 2,500-square-foot ranch requires a 2,500-square-foot foundation and 2,500 square feet of roofing material. A two-story home of the same size only needs half that footprint. Concrete and roofing are two of the biggest line items in any budget.
So, you’re paying for the footprint.
However, you save in other ways. You don't need a massive crane for the second-floor framing. Maintenance is a breeze. Want to clean your gutters? You need a six-foot ladder, not a death-defying 24-footer. Painting the exterior? You can do it yourself over a weekend. These "hidden" savings add up over twenty years of homeownership.
Accessibility is no longer an "old person" feature
Universal Design is the new cool. According to the AARP, nearly 90% of adults over age 65 want to stay in their current homes as they age. But younger buyers are catching on too.
If you’ve ever tried to carry a sleeping toddler, a laundry basket, and a vacuum cleaner up a flight of stairs, you know the struggle. Single story house design eliminates the "vertical tax" on your knees and back.
- Zero-threshold entries: No tripping over the front door sill.
- Wide hallways: Typically 42 to 48 inches instead of the standard 36.
- Curbless showers: They look like a high-end spa and function for everyone.
It’s just easier. Life is hard enough; your house shouldn't be an obstacle course.
The indoor-outdoor connection
This is where the ranch style really wins. In a two-story house, the upstairs bedrooms are isolated from the yard. In a one-level home, every single room can have a door to the outside.
Imagine a "U-shaped" or "L-shaped" floor plan wrapped around a central courtyard. You can wake up, slide open a glass door in your bedroom, and step right onto the patio for coffee. It creates this sense of "resort living" that you just can't get when you're perched twenty feet above the grass.
Modernists like Joseph Eichler pioneered this in the mid-century, and it’s still the most effective way to make a small footprint feel massive. By using the same material for the indoor floor and the outdoor patio—like a continuous slate tile—the eye doesn't see a boundary. The room just keeps going.
Sunlight management
Because you have more roof surface area, you have more opportunities for natural light. Skylights, solar tubes, and clerestory windows (those narrow windows high up near the ceiling) can pull light into the very center of the house. Even a windowless interior hallway can be flooded with sun.
Real-world examples of the "Modern Ranch"
Look at the work coming out of firms in Austin or Palm Springs. They aren't building "boxes." They’re building "pavilions."
Take the Courtyard House concept. By literally carving a hole in the middle of the house plan, you bring light and air into every room. It’s a centuries-old technique used in Mediterranean and Asian architecture that works perfectly for the American single-story home. It provides total privacy from the neighbors while keeping the interior bright.
Sustainability and the "Long Home"
There is a movement toward "Passive House" standards in single-level living. Because these homes are easier to seal and insulate, they can be incredibly energy efficient.
The roof is also a factor. A larger roof means a larger area for solar panels. If you’re looking to go off-grid or just hit "Net Zero," a single-story design gives you the real estate to capture enough photons to power your whole life, including your car.
Actionable steps for your design process
If you’re sitting down with an architect or browsing floor plans online, don't just look at the pretty pictures. Look at the logistics.
- Check the "Circulation Path": Imagine walking from the garage with six bags of groceries. Do you have to weave through the living room and past the guest bath to get to the kitchen? If so, the plan is bad. You want a direct shot from the "mudroom" to the pantry.
- Audit the Window Placement: In a one-story home, privacy is paramount. Ensure bathroom windows are high-set or frosted. Make sure your bedroom doesn't look directly into the neighbor’s kitchen.
- Think About the "Fifth Wall": That’s your ceiling. Since you don’t have a floor above you, use that space. Vault it, tray it, or add exposed beams. This is the primary way to add character to a ranch.
- Size the Foundation Right: If you’re on a slope, a single-story home might require a "walk-out basement." This gives you the best of both worlds—one-level living for you, and a separate "lower level" for guests or storage that doesn't feel like a basement.
- Focus on the Entryway: Without the grand staircase to impress guests, the foyer needs to do the heavy lifting. A wide glass pivot door or a unique lighting fixture can set the tone immediately.
Single story house design is about simplifying. It's about acknowledging that we spend most of our time in three or four rooms anyway. By putting everything on one plane, you aren't just building a house; you're designing a lifestyle that is inherently more connected, accessible, and frankly, more relaxed. Forget the "rambler" of the past. The modern one-level home is a masterpiece of efficiency and light.
Invest in the footprint. Maximize the glass. And for heaven's sake, give yourself a pantry that doesn't require a hike from the car. That's the real secret to a home you'll love forever.
