Single-story homes are a popular choice because they allow for barrier-free living without the need for stairs, but many people still have the impression that "construction costs are high." In practice, it is also possible to build a new single-story home for under 10 million yen. This article explains the key cost-saving strategies and important layout considerations.
What are the key ways to keep a new single-story home under 10 million yen?
Keep the exterior design and structure simple
A home with a simple shape uses fewer building materials and requires less labor, which helps reduce construction costs. In recent years, many single-story homes have achieved a modern, stylish appearance even with a simple design, making it possible to lower costs without sacrificing visual appeal.
Review the grade of fixtures and materials
For home fixtures such as system baths and washstands, it is better not to downgrade everything across the board. The important point is to create a clear balance: keep essential everyday features at or above the standard grade, while limiting lower-use fixtures to the minimum necessary. By choosing fixtures with your actual lifestyle in mind, you can maintain comfort while keeping costs under control.
Request estimates from multiple builders
You cannot understand the market level of construction costs from one estimate alone. It is important to request quotes from several companies and choose one with substantial experience building single-story homes. Large national homebuilders often pass advertising costs into their pricing, so experienced local builders should also be considered.
What are some layout examples for a single-story home built on a 10 million yen budget?
A 2LDK to 3LDK layout is a realistic option
A 2LDK to 3LDK floor plan is relatively manageable within a construction budget of around 10 million yen, and it provides sufficient space for a household of two to three people. A common benchmark is an 18-tatami living-dining area plus two western-style rooms of 6 tatami each.
Make the living-dining area the core of family life
By limiting the number of rooms and giving more space to the living area, you can create a comfortable LDK where the family naturally gathers while also reducing costs. Even adding just one tatami of extra space can make a noticeable difference in comfort.
Concentrate the water-related areas
A single-story home has no second floor, so plumbing cannot be consolidated vertically. Placing the kitchen, bath, and wash area close together shortens the drainage lines and helps reduce costs.
Ensure good ventilation and sunlight
Even with a lower budget, comfort still matters. If sunlight and airflow are poor, lighting, dehumidification, and air-conditioning costs will increase. Ask your designer to carefully consider orientation and window placement during the planning stage.
Use partitions to accommodate future changes
If you incorporate partitions such as sliding doors or movable dividers, you can flexibly adapt the layout as your family grows and changes. Even with fewer rooms, it is still possible to create a flexible living environment.
