Everything on One Level, No Stairs

Custom One-Story House Plans

Single-level living is the most-requested layout in the country right now — no stairs, easier accessibility, and a floor plan where everyday life happens on one plane. But a one-story spreads across your lot, so the way rooms are zoned and how the home meets its site matters more, not less. That is what a custom single-story plan gets right.

The One-Story Layouts People Ask For Most

These are the configurations that come up most on our single-story briefs.

Split-bedroom ranch

Primary suite on one side, secondary bedrooms on the other, with living in between — the most popular single-story layout for privacy.

Open-concept great room

Kitchen, dining and living combined into one bright space at the heart of the home, with bedrooms tucked to the ends.

Accessible / aging-in-place

Wider halls and doors, a zero-step entry, a curbless shower and a primary bath designed to adapt as you age.

Courtyard single-story

An L- or U-shaped plan wrapped around a private outdoor courtyard, bringing light deep into a wide footprint.

One-story with bonus above garage

True single-level living for daily life, with an optional bonus room over the garage for guests or hobbies.

Compact efficient ranch

A tight, well-zoned single-story that keeps the footprint and the build budget small without feeling cramped.

What Shapes a One-Story Plan Before You Draw It

These are the decisions that make single-level living work well.

Bedroom zoning

With everything on one floor, keeping bedrooms acoustically and visually separated from living space is the key to a one-story that feels private.

Lot width & spread

A single-story needs more footprint than a two-story of the same size, so lot width, setbacks and shape drive the plan more directly.

Natural light

Wide single-story plans can go dark in the middle. Courtyards, higher ceilings and clerestory windows are designed in to bring light deep inside.

Accessibility

Zero-step entries, wider halls and doors, and a curbless primary shower are easy to design in now and expensive to add later.

Roof & ceiling interest

Vaulted and tray ceilings give a single-story the volume a stacked home gets for free. Those are drawn with the roof structure.

Garage & entry

On a single level the garage, mudroom and entry sequence shape the whole plan and how daily life flows in from the car.

Why Single-Story Homes Reward a Custom Plan

A one-story spreads out, so a stock plan drawn for a different lot fights your width, your setbacks and your light. Zoning that keeps bedrooms quiet and brings daylight into the center is specific to your site — and it is exactly what gets compromised when you force a catalog plan onto your lot.

What It Actually Costs to Build a One-Story Home

Single-story homes carry a larger foundation and roof per square foot than a two-story, which can nudge the cost per square foot up, but they save on stairs and are simpler to frame. Finish level still drives the total, so pricing your real build before you design keeps the plan on budget.

A state-adjusted, 14-category cost report prices your single-story build by county, so you can see how size and finish change your cost per square foot.

Frequently Asked Questions

Are one-story houses more expensive to build than two-story?

Per square foot they can be slightly more, because a single-story spreads the same area over a larger foundation and roof. But they save on stairs and are simpler to frame, and the difference is modest. A location-adjusted cost report prices your specific build.

Can I get a single-story plan designed for aging in place?

Yes — that is exactly what our Design Your Dream Home service does. Ask for accessible features and a designer draws a zero-step entry, wider halls and doors and a curbless primary shower into your complete custom plan set from $899, typically in 7 to 11 business days with a free revision round. You start with a $300 deposit and pay the balance only after you approve your floor plan.

What is a split-bedroom floor plan?

It is a single-story layout with the primary suite on one side of the home and the secondary bedrooms on the other, with living space in between. It is the most popular one-story layout because it gives the primary real privacy, and your designer can draw it around your rooms.

Do single-story homes need a wider lot?

They need more footprint than a two-story of the same size, so lot width and shape matter more. Your plan is drawn to your exact setbacks and lot, and a courtyard or L-shape can fit a surprising amount of home on a modest lot.
