Formula for calculating the price of raw house construction
ROUND CONSTRUCTION COST (VND) = Unit price (VND/m²) x converted construction area (m²).
CONVERSION CONSTRUCTION acreage (m²) Rough part = Area of converted foundation + Area of ground floor + Area of floors of floors + Area of Roof tilt coefficient + Area of converted auxiliary works.
CONVERSION FACTOR: CONSTRUCTION AREA = Area x coefficient (%)
NOTE:
+ Why is there the concept of "conversion" in the above formula? The reason is that the construction area will be larger, smaller or equal to the floor area, depending on the type of construction item.
+ In general:
Only for the ground floor, mezzanine and upper floors, if the conversion factor is 100%, the construction area will be equal to the actual area.
The basement has construction space larger than the actual area.
The remaining items have construction areas smaller or equal in area.
In fact, costs will arise for difficult designs, such as zigzag stairs or console stairs. The cost will be higher than that of slab stairs.
In addition, to calculate the price of building a complete house, many other costs are needed such as furniture costs, finishing material costs, garden costs, fence gates, etc.
5 factors affecting the price of raw house construction
Just like when calculating design costs, the price of building a rough house is also influenced by many factors. For example, the scale of the project, type of materials, and geology of each area affect the cost of foundation work, foundation processing, etc. In addition, the unit price of building the rough part of a high-rise building and the unit price of building the rough part of a townhouse also have certain differences.
Factors affecting quotes for rough construction at S-House
You need to research and consult the construction unit to have the most accurate calculation. From there, you can estimate the necessary costs.
1. Project scale
For large-scale projects, Quotation for rough construction will be lower than small-scale projects. It can be simply understood that if the house size is large, more materials will be needed. At that time, the wholesale price of construction materials will be lower than when buying retail. This rule is applied in calculating the rough construction unit price of most construction units and companies.
2. Labor cost for rough construction
Depending on each locality, the cost of raw construction labor will vary. In addition, it also depends on the skill level of the construction team, the complexity of architectural details, the location of the project, the homeowner's progress requirements, and the cost of ensuring labor safety...
3. Geological structure affects the type of construction foundation
Depending on the condition of the ground, S-House will quote the exact rough house construction price for the foundation to the customer. For example, if the site is small, subsidence, low-lying, etc., costs must increase due to the need to reinforce the foundation and longer construction time.
4. Raw construction materials
The price of rough construction materials such as sand, stone, cement... of each brand, type and quality will be different. S-House will be based on the materials the customer wants to use to give the construction unit price.
Not only that, the price of raw materials constantly fluctuates depending on the time of year and season. If you determine a time to build a house that is longer than the time of the predetermined cost estimate, you need to have a backup financial plan.
5. House design drawing
Blueprint home design greatly affects construction costs. From the shape of the house to the density of functional layout. The more areas and more small and meticulous details a house has, the higher the cost.
Design is an important stage to prepare for rough construction. Next, you need to consider how you intend to use the house. If you want the house to be more sustainable over time, construction plans for beams, high wall thickness, etc. should be taken into account. This leads to a change in the volume of materials and construction time, leading to an increase in the price of building a rough house.
Besides, other functional solutions such as soundproof walls, anti-vibration... also lead to changes in the unit price of raw and finished construction.
Note when constructing rough parts to save costs
To ensure an accurate estimate of the cost of building the rough part of the house, as well as minimize costs incurred, the following points should be noted.
1. Limit changes to design and construction plans
S-House provides a price list for building a rough house, which must be based on the architectural design and structural drawings previously finalized. If during the construction process there are changes in design, it will lead to changes in the cost of building a rough house.
For the foundation, based on geology, the architect will provide solutions and choose the appropriate foundation type. In this regard, homeowners should listen to the advice of architects and construction engineers.
Note when constructing rough parts to save costs
2. Learn about the price of raw construction materials
The rough construction price list above includes construction materials. Therefore, when estimating costs, the homeowner needs to ask S-House to provide a detailed list of materials used.
Accordingly, depending on the quality, raw construction materials have different prices. At the same time, depending on the time, the prices of these materials will vary.
3. Choose construction options and investors
Many homeowners choose to buy the materials themselves and hire workers to build according to the design. This option seems to be more economical because the homeowner will find a good supplier and labor may be cheaper. But in reality it is not like that.
Because if you don't know how to choose materials and reputable suppliers, it's easy to buy at high prices and not guarantee quality. Furthermore, the homeowner has to spend a lot of time monitoring and ensuring the quality and progress of the project.
In general, the cost is even higher when choosing a complete house design and construction plan, from rough construction to completion.
It is a fact that there are always increases or decreases in the house building process. S-House will always advise and anticipate these increases and decreases. Any increase or decrease will always be informed in detail and continuously to the homeowner.
