Breakdown of Construction Costs, a breakdown showing how the total construction cost of a villa is divided between the structural system (rough construction) and finishing work (finish work). Understanding this breakdown makes it possible to identify which line items offer opportunities for savings and which pose risks when planning a budget.
In this article, we do not provide specific amounts or percentages because material prices and labor costs fluctuate rapidly from time to time, and a figure that is current at the time of publication can quickly become misleading. Instead, we discuss the relative weight of each item and what determines their cost. A site survey is required to prepare an up-to-date budget.
What Determines the Cost of Rough Construction?
Structural work includes the load-bearing system, which consists of the foundation, columns, beams, shear walls, and floors. The factors that determine the cost are quite limited and predictable:
- Amount of concrete and reinforcing steel: It depends on the project's square footage; whatever the structural calculations indicate is final—it is not subject to negotiation.
- Basic type: It depends on the results of the soil survey; foundation costs increase significantly on weak soil
- Excavation and earthwork: The slope of the land, rock conditions, and transportation distance
- Mold system and workmanship: The quality of the formwork system used and the team's efficiency
- Number of floors and geometry: Consoles, wide spans, and irregular floor plans increase the amount of reinforcement
The critical feature of rough construction is this: it is not preference but calculation that determines the specifications. For this reason, “cost-cutting” in rough construction generally means deviating from the project plan and directly affects structural safety.
What Determines the Cost of Fine Work?
Finishing work is a broad category of tasks ranging from insulation to plastering, from plumbing to flooring and furniture. The main difference from rough construction is that the cost is largely preference is that it is linked to:
- Coating options: The difference between ceramic, natural stone, hardwood flooring, or microconcrete can significantly affect the total budget
- Cutting: The profile system, glass unit, and dimensions are a significant factor in and of themselves
- Kitchen and bathroom fixtures: Countertop materials, cabinet hardware, and faucets vary widely in quality
- Mechanical systems: Choices such as underfloor heating, VRF, and heat pumps affect both the initial investment and operating costs
- Custom-made products: Swimming pools, saunas, Turkish baths, smart home systems, and landscaping are added to the project as separate budget line items
General Weight Relationship
In a standard-spec villa, finishing work represents a larger cost category than structural construction. As the level of finish increases, this gap widens: as luxury finishes, custom millwork, and additional custom work are added, the share of structural construction in the total cost becomes relatively smaller. Conversely, as site conditions become more challenging—for example, on a lot requiring a specialized foundation solution—the share of rough construction may exceed expectations.
For this reason, general statements such as “the cost of a villa is X per square meter” are meaningless unless it is specified which level of amenities and which type of land are being referred to.
Common Mistakes When Planning a Budget
- Setting a budget based solely on the shell of the building: Once the structural system is complete, it may seem as if the job is done; yet the bulk of the expenses has not yet begun
- Thinking of insulation as merely a decorative touch: Water and thermal insulation are the items with the highest retrofit costs. On this topic In our article on waterproofing we addressed
- Forgetting items not included in the project: Permit fees, building inspection fees, utility connections, landscaping, and furniture are often left out of most budgets
- Making decisions during construction: Delayed decisions on materials result in both supply delays and budget overruns
Frequently Asked Questions
If the budget is tight, where should cuts be made?
Cost reductions should be made in the finishing elements, not in the structural system or insulation. The finish class can be reduced, and some construction work can be postponed to a later stage. However, cost-cutting measures regarding concrete grade, reinforcement, waterproofing, and thermal insulation will result in much greater expenses over the life of the structure.
How can costs be calculated reliably?
Quantities are calculated based on the approved project, current unit prices are applied to each line item, and a cost estimate summary is prepared. Calculations made before the project is finalized are merely estimates. For the general framework, Our article on the cost of building a villa You can review it.
Does it make sense to hire separate companies for the rough construction and the finishing work?
It is possible, but it carries the risk of blurring the lines of liability. Especially in areas where two groups overlap—such as insulation—it can become a matter of debate whose responsibility it is when a defect arises.
The Imerek Construction Approach
We handle the rough construction using our own formwork system and our own team, while we provide transparent, itemized estimates for the finishing work. Please contact us to receive an up-to-date estimate for your project.
