Single Story House Plans
Single story house plans put every room on one level with no stairs to climb, which can suit families with young children, older owners and anyone planning to stay put. These single-floor plans grow from one bedroom to four along the same hallway, so you can pick by bedroom count and compare footprints.
A single-story family layout

One hallway, any number of bedrooms
The 1- to 4-bedroom templates share a pattern: a 1.2 m (3′ 11″) hallway runs from the front door through the middle of the house, with living rooms on one side and bedrooms and the bathroom on the other. Each added bedroom makes the house longer while the depth stays at 9.7 m (31′ 10″); the 4-bedroom plan keeps the 3-bedroom footprint and turns the dining room into a bedroom.
You adapt them all the same way. To add a room, lengthen the house; to shorten it, delete a room and pull the end wall in. Because every room except the hallway sits on an outside wall, each one keeps its window when the house grows.
Single-floor layouts by size
| Bedrooms | Footprint | Total room area | |
|---|---|---|---|
| 1 Bedroom | 1 | 7.8 × 9.7 m (25′ 7″ × 31′ 10″) | 75.7 m² (814 sq ft) |
| 2 Bedroom | 2 | 9.8 × 9.7 m (32′ 2″ × 31′ 10″) | 95.1 m² (1,023 sq ft) |
| 3 Bedroom | 3 | 13.8 × 9.7 m (45′ 3″ × 31′ 10″) | 133.9 m² (1,441 sq ft) |
| 4 Bedroom | 4 | 13.8 × 9.7 m (45′ 3″ × 31′ 10″) | 133.9 m² (1,441 sq ft) |
Planning a single-story house
Keep bedrooms together
Grouping bedrooms on one side, as the 1- to 3-bedroom plans do, keeps the living areas from becoming a corridor.
Watch the walking distances
On one floor the routes get long. Use the measure tool from each bedroom to the bathroom and from the kitchen to the table.
Plan for wide doors
Select a door and type a wider width where you want easier access, then check it in 3D.
Use the plot shape
Long, narrow plots suit the hallway plans; add a wing off a corner for an L-shape on a wider plot.
Things to consider
Footprint and roof
Everything on one level means a larger footprint than the same rooms over two floors. Compare with the two-story villa if the plot is tight.
Accessible design
Step-free entrances, door widths and bathroom space are set by local guidance where you live. Check it if accessibility matters to you.
Bathrooms
Each hallway plan has one bathroom by the front door. Larger households usually add a second at the bedroom end.

Frequently asked questions
Which single-story plan should I start from?
The one with your number of bedrooms. All four share the same hallway pattern, so adding or removing a bedroom later is a matter of moving the end wall.
Can I add a basement to a single-story plan?
Yes. Use Add floor below and connect it with a stair. The house then has two levels, but the main living stays on one.
Can I make a single-story plan L-shaped?
Yes. Draw a wing off any corner with the wall or room tool; every enclosed space becomes a room with its own area.
Can I see the whole house in 3D?
Yes. The 3D view shows the walls, doors, windows and furniture, and walk mode lets you move through it at eye level.
