Besides construction and finishing costs, interior design costs also account for a large proportion of a home’s expenses and are a major concern for many homeowners. Understanding this, 3A Design will outline the factors to consider when estimating interior design costs for a new home. If you are planning to build or renovate your house, read this article to avoid unnecessary expenses.
What Factors Constitute the Cost of Residential Interior Design?
The interior cost of each house varies depending on architectural factors and the client’s functional needs. However, the basic residential interior cost is composed of the following three factors:
Interior Design Cost
Through the 3D interior layout of the house, the homeowner can visualize the arrangement of items in their living space. A detailed and harmonious interior design blueprint not only ensures the aesthetic quality of your home but also maximizes the house’s functional utility. Currently, the interior design cost is usually calculated using the formula:
Design cost = total design area x unit price per m2

Interior Construction Cost
This is also a contributing factor to the total residential interior cost. The interior construction cost is divided into two parts, including:
- The cost of executing the construction of interior fixtures designed according to the homeowner’s specific needs.
- The cost of transportation and installation of equipment according to the initial interior design blueprint.
Cost of New Furniture Purchase
In reality, the contractor can only provide a list of necessary interior equipment for the house after the interior design blueprint is finalized. The homeowner will then discuss adding or removing furniture based on their usage needs. Generally, the cost of household interior items will depend on the brand and quality. Furniture in the mid-range segment will have a lower price than high-end furniture.
Interior equipment provided by the design and construction unit includes: TV stands, kitchen cabinets, kitchen counters, wardrobes, dining tables, washbasins (lavabo), toilets, bathtubs, etc. Other household items, such as: TV, refrigerator, washing machine, air conditioner, fans, sofas, lighting, decorative paintings, etc., will be selected by the homeowner based on their usage requirements.

Reasons to Pre-Estimate Residential Interior Costs
Pre-planning and estimating interior costs not only helps homeowners avoid cost overruns during execution but also ensures the construction progress adheres to the projection.
- Avoid Unforeseen Costs: When hiring an interior design unit, the architect will provide the homeowner with a detailed inventory list of necessary equipment for the house. Both parties can then discuss and adjust the furniture based on usage needs. This prevents you from making wasteful, emotionally-driven purchases.
- Ensure Construction Timeline: Budgeting helps the homeowner prepare all necessary interior equipment for their house in advance. The contractor can then execute construction, transportation, and installation of the interior exactly according to the timeframe agreed upon in the contract. The homeowner can move into the house as planned.
- Balance Home Construction Costs: Building a new house involves many items, such as: architectural interior design, rough construction, rough house finishing, and interior finishing. Most investors planning to build a house have already considered the financial capacity they can allocate for a completed house. Detailed interior cost estimation helps the homeowner balance the necessary costs for each component.
