One-story house plans put everything on a single level for the ultimate in convenience, accessibility, and easy living. House & Timber Plan Co.'s single-story collection features open floor plans with no stairs to navigate, making these homes perfect for families with young children, anyone planning to age in place, and homeowners who simply prefer the practicality of one-level living.

Our one-story floor plans range from 1,000 to 3,000+ square feet with 2 to 4 bedrooms and 1.5 to 3 bathrooms. Popular features include open-concept great rooms, split-bedroom layouts for privacy, attached garages with mudroom entries, covered porches and patios, and primary suites with spa-style bathrooms and walk-in closets.

Single-story homes are easier to maintain, clean, and navigate than multi-story designs. All mechanical systems, plumbing, and electrical are accessible without climbing stairs. There's no need to carry laundry between floors, and every room is immediately accessible from every other room. These practical benefits make one-story plans consistently popular.

Common Questions

FAQ

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

One-story homes cost 10-15% more per square foot than two-story homes of the same total area because they require a larger foundation and roof. However, the simpler framing, reduced scaffolding costs, and easier access during construction can partially offset this. Overall, one-story homes cost slightly more per square foot.

How wide does my lot need to be for a one-story house?

One-story homes need wider lots because the entire living area is on one level. A 1,800 sq ft one-story plan typically needs a lot 70-90 feet wide, compared to 50-60 feet for a two-story of the same size. Check your plan dimensions against your lot survey after subtracting required setbacks.

Can one-story house plans have basements?

Yes, many one-story plans offer full or walkout basement options, which effectively doubles the home's usable space. A one-story home with a finished basement provides the accessibility benefits of single-level living with bonus space below for recreation, storage, guest rooms, or a home gym.

What styles work best for one-story houses?

Ranch is the classic one-story style, but farmhouse, craftsman, modern, cottage, and contemporary plans all work beautifully as single-story designs. Farmhouse plans with covered porches and ranch plans with open layouts are the most popular one-story options in our collection.
