In modern society, owning a home of your own is the dream of many people, and building your own home is gradually becoming the choice of more and more people. However, from the initial planning to the final move-in, I believe many people will want to know how many square feet of 40-square-meter land can actually be used to build a house, whether the house should be built as a bungalow or a large house, and how much it costs to build a 40-square-foot house. And design cases will be compiled for you through this article.

How many square feet can be built on 40 square feet of land for self-construction? You need to first understand "floor area ratio" and "building coverage ratio"
When we evaluate whether to build a house on a 40-square-meter land, we first need to understand two important building parameters: floor area ratio and building coverage ratio. These two values will directly affect the total area we can build on this land and the floor area of the building. The following paragraphs will provide detailed instructions and calculation methods:
What does the calculation source of floor area ratio and built-in coverage ratio depend on?
Floor area ratio and built-up coverage ratio are two important indicators in building planning. Their calculation sources depend on the following three factors. These factors jointly determine the area and form of buildings that can be built on each piece of land, ensuring that during the urban development process Achieve a balance between economic, environmental and social benefits. Understanding these backgrounds will help us make more appropriate and compliant design plans before self-construction.
Urban Plan
The urban plan is a blueprint for urban development, planning the development direction of each city or region. Each area type will have specific floor area ratio and built-in coverage ratio requirements. These values are usually determined by the government or relevant regional planning departments based on the overall development of the city. goals to set. For example, commercial areas may have higher floor area ratios and built-up coverage ratios, while residential areas may have lower values to retain more environmentally friendly greenery and public spaces.
land use zoning
Divide the land according to its nature of use. Each land use type has specific floor area ratio and coverage ratio restrictions. For example, industrial land, commercial land, residential land, etc. have different building codes. These restrictions are to ensure that the land can be used rationally and to avoid over-development or waste.
regulations
Domestic building regulations also have specific provisions on floor area ratio and building coverage ratio. These regulations usually set relevant standards based on public safety, environmental protection, transportation needs, etc. For example, some areas may reduce the floor area ratio to meet disaster prevention needs, or limit the building coverage ratio to protect historical and cultural areas.
What impact do coverage ratio and floor area ratio have on buildings? How to check the construction rate and floor area ratio of a base?
The influence of building coverage rate
Building Coverage Ratiorefers toRatio of building projected area to building base area. A high built-up coverage ratio means that more land is covered by buildings, thus reducing the area and use scope of green spaces and public open spaces; a low built-up coverage ratio provides more outdoor space and green environment, which can improve the degree and quality of environmental beautification. The coverage ratio of low-density residential areas is 30% to 50%, that of medium-density residential areas is 50% to 70%, that of high-density residential areas is 70% to 80%, and that of commercial areas exceeds 80%.
The impact of floor area ratio
Floor Area Ratio (FAR)refers toThe ratio of a building's total floor area to its base area, refers to how much the total floor area of the house can be based on the base area. A high floor area ratio allows the construction of taller buildings and is suitable for densely populated areas; a low floor area ratio helps create low-density residential areas, with a floor area ratio of 30% to 50%, medium-density residential areas of 50% to 100%, and high-density residential areas of 100% to 200%, and the commercial area exceeds 200%. For example, on a piece of land of 40 square meters, if the floor area ratio is 30%, the total floor area is 12 square meters, and if the floor area ratio is 200%, the total floor area is 80 square meters.
How to check the construction ratio and floor area ratio of the site?
If you want to check the built-up coverage ratio and floor area ratio of your land, you can useNational land use zoning data queryorMinistry of Interior Real Estate Information Platform, just enter the county, city, lot and land number where the land is located. You can also directly consult the relevant units of the local government, or check the land registration book.
How much does it cost to build a 40 square meter house? What factors affect costs? Sharing of self-built processes
If calculated based on standard specifications, building materials, and construction land suitable for construction, the cost per square meter for self-construction starts from approximately 150,000 to 170,000 yuan. If the housing prices or land value in the area are high (such as Taipei, New Taipei), the cost per square meter will start from about 170,000 to 250,000 yuan, and interior decoration and architectural design costs are not included.
Reasons why self-construction affects costs
location of land
Including the shape, location, geology and other conditions of the base, as well as whether the surrounding roads are narrow and whether the access of people or equipment is inconvenient, they will also directly affect the difficulty and requirements of construction.
Building structural engineering methods
Common construction methods such as RC (reinforced concrete), SRC (steel reinforced concrete), SC (steel structure), the cost, difficulty, time and other factors required for each construction method will all affect the cost.
Materials used in construction
The cost per square meter provided above is an estimate based on the use of general building materials. If the type and quality of the required materials are different, the price will also be different, which will affect the total construction cost.
Take a look at the eight major processes of self-construction at once
In the process of self-construction, although each step can be completed by yourself, if you can combine the assistance of a professional team, you can save more time and effort during the construction process. From land selection, design planning, construction management to final acceptance, a professional team can help avoid potential legal issues or details and ensure that the final result is a living space that meets expectations and is safe. The following provides the content and scope of services that the professional team can assist, in order toB-studioFor example:
1.Consultation and proposals
2. Building and site analysis
3. Design stage
4. Project contract evaluation stage

Through the above eight processes, the blueprint is gradually transformed into a dream house, so that everyone can have a comfortable and safe living environment.
