Single-story homes have been drawing renewed attention in recent years as simple residences where daily life is completed on one floor. Many people assume that “single-story homes are expensive,” but they can be built affordably with the right design choices. This article introduces three cost-saving tips, the main advantages, and real-world examples.
What are the key points for building a low-cost single-story house?
The following three approaches are effective for reducing the cost of a single-story home.
Choose standard specifications
By following a builder's standard specifications, you can reduce costs through bulk material purchasing and more efficient construction. Clearly telling your representative, “I want to build with the standard specifications,” is the first step.
Keep the floor plan simple
The closer the shape is to a cube or rectangular box, and the simpler the floor plan is, the lower the cost becomes. That is because less processing is required for walls and doors, reducing both material costs and labor hours.
Select equipment with strong cost performance
It is important to choose equipment that “produces” energy rather than only “consumes” it. Homes designed to meet ZEH (Net Zero Energy House) standards may qualify for government subsidies, helping reduce upfront costs while also lowering utility expenses.
Two main advantages of a low-cost single-story house
Easier to secure parking space
Lower construction costs make it possible to purchase a larger lot. Eliminating parking fees of 30,000 to 50,000 yen per month in urban areas can create significant long-term savings. This is especially important in regions where driving is part of daily life.
Easier to qualify for a home loan
Keeping total costs down reduces the borrowing amount, which means the repayment burden ratio declines and the likelihood of loan approval increases. Even if you already have existing debt, a lower loan amount can improve your chances of passing the screening process.
Examples of low-cost single-story homes
Example 1: A home tailored to everyday living
This single-story home, built in a densely populated residential area, incorporates a doma-style passage, a sloped ceiling, and a skylight. It achieves an open space that overturns the idea that “single-story homes feel cramped” through the use of large windows. Even when based on standard specifications, thoughtful design can create a rich sense of private comfort.
Example 2: A home that makes use of a loft
By using the loft area for hobbies or as a play space for children, the design creates a greater sense of spaciousness without increasing total floor area. It is a low-cost design that still does not feel confined.

Frequently Asked Questions (FAQ)
When comparing the same total floor area, which costs more: a single-story house or a two-story house?
In general, a single-story house is slightly more expensive because the foundation and roof area are larger. However, since the exterior wall area is smaller and equipment costs can be lower, the overall cost difference depends on the design.
What is the approximate cost per tsubo for a low-cost single-story house?
For low-cost home builders, a general benchmark is 300,000 to 500,000 yen per tsubo. Choosing standard specifications and a simple floor plan makes it easier to stay within this range.
What are the requirements for receiving a ZEH subsidy?
Requirements include conditions such as reducing primary energy consumption by at least 20% compared with the reference value. Because the builder often handles the application on the homeowner's behalf, it is best to confirm this during the design stage.
Is a single-story house suitable as a home for later life?
Living on one floor without stairs can reduce the risk of falls later in life, making it one of the most suitable housing forms for barrier-free design.
Can a single-story house also qualify for the home loan tax deduction?
If it meets the building requirements, such as a floor area of 40 to 50 square meters or more, and the occupancy requirements, it is eligible for the home loan tax deduction just like a two-story house.
