The calculation of home improvement design costs is usually related to several factors, one of the most important of which is the area. When determining the cost of home decoration design, the design company or individual designer will generally calculate the cost based on the actual area or floor area of the renovated house. Here's a detailed explanation of how the home improvement design fee is calculated by area.
1. Billing model
1. Calculated according to the construction area
The cost of home improvement design is usually calculated based on the floor area. The floor area includes the usable area of the interior of the house, as well as the area occupied by walls, columns, etc.
2. Calculated according to the actual usable area
Some designers or design firms may calculate the design fee based on the actual usable area, that is, the space that can actually be used after removing the occupied area such as walls.
3. Mixed billing methods
In some cases, the design fee may be combined, i.e. the basic fee is calculated according to the floor area, and the additional service fee (e.g. soft decoration design) is calculated according to the actual usable area.
2. Calculation of fees
1. Basic design fee
The basic design fee is calculated per square meter, and different design companies and designers charge different standards, generally ranging from 50 to 300 yuan per square meter.
2. Additional service fee
Additional charges may apply for premium services, such as custom furniture design, artwork selection, lighting design, etc.
3. Calculation of the total cost
Total Design Fee = Basic Design Fee + Additional Service Fee. The total cost is calculated based on the customer's needs and the size of the property.
3. Influencing factors
1. Designer level
Senior designers or well-known designers usually charge more.
2. Project complexity
The complexity of the design scheme also affects the design fee, and complex projects are often more expensive.
3. Regional differences
Design fees may vary from city to city and region.
4. Design style
Differences in design styles can also lead to differences in design fees, and some styles that require high workmanship requirements may charge more.
4. Precautions
1. Confirm the billing method
Before signing a contract, it is crucial to confirm how the design cost will be calculated.
2. Clarify the content of the fee
It is necessary to clarify which services are included in the design fee to avoid additional costs later.
3. Compare more than one**
Get ** from multiple design companies or designers, compare them, and choose cost-effective services.
4. Sign a formal contract
After the designer or design company is identified, a formal contract is signed to clarify the terms.
The calculation of home improvement design costs is a comprehensive process, involving multiple factors such as the size of the house, the level of the designer, and the complexity of the project. Clarify the billing method and the content of the cost, and compare it reasonably, which can effectively control the budget and save costs while ensuring the quality of the design.
