When people think of a detached house, many imagine a two-story home, but in recent years more people have been choosing a newly built single-story house in search of a simpler way of living. This article organizes why newly built single-story homes are attracting attention, how they differ from two-story homes, and what to keep in mind when building one.
Why Is a "Newly Built Single-Story House" Getting Attention Now?
The main reasons newly built single-story houses are chosen are ease of barrier-free design, efficient household flow, and strong durability. They are an effective long-term housing choice for those also considering future care-related renovations.
Well Suited to Barrier-Free Design
Because it is difficult to convert a two-story house into a single-story one later, choosing a single-story house from the outset makes future care-related renovations easier. In an aging society, this has drawn growing attention from the standpoint of creating a home people can continue living in.
Efficient Household Flow
Because all living spaces are consolidated on one floor, it is easier to create a floor plan that minimizes movement for laundry, cleaning, cooking, and other household tasks.
High Durability
A single-story house is structurally stable, and because it is lighter in weight, it experiences less shaking during an earthquake and can limit damage. With no upper floor, the load on the building as a whole is also smaller.
How Do Two-Story and Single-Story Houses Differ? Four Points to Compare
No Stairs
Eliminating the need to go up and down stairs provides two benefits at the same time: greater everyday efficiency and better barrier-free accessibility.
Easier Maintenance
Because a single-story house has only a ground floor, exterior wall and roof maintenance often does not require scaffolding, which can help reduce upkeep costs.
Construction Costs Tend to Be Higher for Single-Story Homes
Somewhat surprisingly, a single-story house can cost more to build than a two-story house. This is because the lot area, foundation work, and roof size all tend to be larger than those of a two-story home.
A Larger Lot Is Required
If you want to secure the same total floor area, a single-story house requires more land than a two-story house. It is important to consider the balance with land acquisition costs.
What Should You Watch Out for When Building a New Single-Story House?
Floor Plan Design That Protects Privacy
Because all living spaces are gathered on the same floor, maintaining privacy between family members can be a challenge. An effective approach is a circulation plan that places the living room in the center and separates individual rooms on both sides.
Insulation Measures Are Essential
Because the roof is close to the living space, the home can easily become hot in summer and cold in winter without proper insulation measures. It is worth considering insulation materials and insulating roof coatings.
Careful Planning for Natural Light and Ventilation
If the surrounding area is lined with two-story buildings, sunlight and natural light can easily become insufficient. By installing an inner courtyard and placing multiple windows facing each other in each room, you can secure both ventilation and natural light.
To further improve residential comfort, it is also helpful to review the costs of equipment additions and renovation work.
Frequently Asked Questions (FAQ)
Q1. Which is more expensive to build, a single-story house or a two-story house?
In general, a single-story house tends to cost more. This is because the lot area, foundation work area, and roof area all become larger. With the same budget, costs can be controlled by reducing total floor area and adopting a simpler design.
Q2. How large should a lot be for a single-story house?
For a family of four to live comfortably, if the building coverage ratio is 50%, a lot of at least about 30 to 35 tsubo is a general guideline. In areas with a low building coverage ratio, more than 50 tsubo may be required.
Q3. Are single-story houses resistant to earthquakes?
Because they have a low center of gravity and a stable structure, they are generally considered more resistant to earthquake shaking than two-story houses. However, ground conditions and construction quality are also important factors.
Q4. What are the advantages of choosing a single-story house for later life?
Because there are no stairs, the risk of falling is lower, and care-related renovations are easier than in a two-story house. In addition, movement throughout the home is shorter, which reduces physical strain.
