One-story house plans: what to compare before you choose

Everything is on one level, so the decisions move sideways: where the bedrooms sit, how far the primary suite is from the kitchen, and how wide the house gets.

ONE STORYLAYOUTGUIDE

A one-story plan removes the stairs and spreads the house out. That makes two things matter more than in a two-story plan: how the bedrooms are grouped, and how wide the house is relative to your lot.

Read the plan as a set of zones (groups of rooms used at the same time of day): arrival, living, sleeping. Then follow the paths between them.

Two one-story zoning patterns. Split-bedroom: the primary suite at one end, living in the middle, other bedrooms at the far end. Clustered: living at one end and all bedrooms grouped together at the other.

Split or clustered bedrooms

Split-bedroom

What it does

The primary suite on one side of the living space, the other bedrooms on the other.

The trade-off

Good privacy for adults; young children sleep across the house from their parents.

Suits

Couples with older kids, hosts, households with a live-in parent.

Clustered

What it does

All bedrooms grouped in one wing off a shared hall.

The trade-off

Easy to hear the kids at night; less separation for guests or a teenager.

Suits

Families with young children.

The main-level primary suite

In a one-story plan the primary suite is always on the main level. What changes is its position. A suite off the kitchen side is convenient; a suite at the end of the house is quiet. Look at which rooms share its walls, and whether the bathroom backs onto a living space.

If you are planning to stay for decades, read the suite as you might use it later: the route from the bed to the bathroom, room beside the bed and in the shower, and a door wide enough on the plan to pass easily. We describe plans like this as aging-in-place friendly only when they are one story with a main-level primary. We never call a plan ADA compliant.

What to compare between plans

  1. 01

    Width against your lot

    One-story plans are often wide. Compare the plan width with your lot width minus the side setbacks before anything else.

  2. 02

    The garage-to-kitchen path

    Follow the route with grocery bags. A mudroom and pantry on the way is the strongest arrival a one-story plan can have.

  3. 03

    Hallway length

    Long halls are the cost of spreading out. Two plans of similar size can differ a lot here.

  4. 04

    Step-free entry

    Check whether at least one entry is drawn without steps. It depends on the foundation and the site, so confirm with your builder.

  5. 05

    Light in the middle

    Wide, deep plans can leave the center of the house dark. Look for windows on the main living space on two sides.

Trade-offs to expect

  • A one-story house covers more of the lot than a two-story house with the same floor area, which leaves less yard and needs more roof and foundation.
  • Split-bedroom plans buy privacy with distance; someone will always be at the far end of the house.

Ask before you buy the plan

  1. What are the overall width and depth, and do they fit inside your lot after setbacks?
  2. Which foundations does the plan set include?
  3. Can the garage turn to the side if your lot needs it?
  4. Are wider doors or a curbless shower already drawn in a version of this plan?
