The turnkey office construction cost typically ranges from VND 6,000,000 – VND 18,000,000/m² or higher, depending on the floor area, level of finish, materials used, technical systems, and the enterprise’s design requirements. To get the most accurate quote, a site survey and clear definition of the scope of work are required.
Below, ATZ LUXURY provides a detailed cost breakdown for each core construction category.

Office Construction Cost Breakdown by Actual Construction Sequence
Phase 1: Foundation and Basement Construction
This is the most complex, costly phase with the highest risk of unexpected expenses, as it depends entirely on the actual geotechnical conditions of the site.
- Bored Pile Construction: To ensure the building’s load-bearing capacity, bored piles are mandatory. The unit price for piles with a diameter of D300 – D600 ranges from VND 435,000 to VND 950,000 per linear meter. For mega-projects requiring D1500 piles, drilling costs can reach VND 5,000,000 – VND 8,500,000 per linear meter.
- Basement Construction: Depending on the depth and shoring method (such as using Larsen sheet piles or Barrette slurry walls deep into hard soil combined with Bentonite mud), the average basement construction cost ranges from VND 5,000,000 to VND 10,000,000/m².
Phase 2: Office Building Structural Rough Construction
The rough structure serves as the “skeleton” defining the scale and lifespan of the project, typically accounting for about 50% to 55% of the total project budget.
- Standard Unit Price: In the current market, the cost for office rough construction ranges from VND 3,500,000 – VND 4,800,000/m². This category usually accounts for 50% to 55% of the total budget for the entire construction project.
- Steel Frame vs. Reinforced Concrete Solutions: Prefabricated steel frame office construction is a strong trend. Compared to traditional reinforced concrete, steel frames reduce the load on the foundation, shorten construction time to just 2 – 3 months, and optimize structural construction costs by 20% to 30%.
Phase 3: Exterior Architecture and Facade Finishing
Once the structural skeleton is complete, the building envelope directly determines the aesthetics and energy efficiency of the structure.
- Glass Facade Systems: Instead of solid brick walls, modern offices prioritize panoramic glass curtain walls. Depending on the aluminum profile system used (Xingfa, Hyundai) and the configuration (Stick or Unitized system), facade installation costs using laminated safety glass range from VND 1,550,000 to VND 2,700,000/m².
- Floor and Ceiling Finishing Materials: Painting and priming, concealed/exposed grid plasterboard ceilings, and floor tiling cost approximately VND 5,500,000 – VND 7,500,000/m². This price can jump to VND 7,000,000 – VND 10,000,000/m² if the project requires natural Marble/Granite cladding in the main lobby and elevator areas.
Phase 4: Core M&E (Mechanical & Electrical) System Installation
The M&E system acts as the blood vessels and nervous system, determining the microclimate environment and operational capacity of the building.
- HVAC (Heating, Ventilation, and Air Conditioning): Professional buildings are required to use central air conditioning systems (VRV/VRF). Just for the material and labor costs of copper piping (applied to a capacity range of 18,000 – 24,000 BTU), the price is around VND 350,000 per linear meter.
- Low Voltage and LAN Systems: To maintain connectivity for hundreds of employees, systematic network cabling is mandatory. Labor and material costs for CAT5E/CAT6 cables routed above ceilings or under raised floors typically range from VND 180,000 – VND 250,000 per network node.
Notes on Risk Management and Office Construction Budget Optimization
To prevent the budget estimate from spiraling out of control during execution, investors should keep two key factors in mind:
- Stay Ahead of Material Price Fluctuations: Forecasts for 2026 indicate that prices for core bulk materials like steel, cement, and leveling sand will continue to fluctuate and rise slightly due to high infrastructure investment demand. Signing early supply contracts is the best way to “lock in” safe pricing.
- Timing Strategy for Construction: Kicking off underground and rough construction categories during the dry season is a golden rule. Continuous construction without interruptions from heavy rains and storms helps the project eliminate hidden risks such as idle equipment rental fees, daily wages for waiting workers, or rusting and loss of steel exposed to the weather.
Frequently Asked Questions (FAQs) Regarding Office Construction CostsHow long does it currently take to obtain a construction permit for an office building?
By regulation, the processing time for construction permits for projects (including office buildings) is 20 working days from the date the regulatory authority receives a complete and valid dossier. However, with administrative procedure reforms, this timeframe is proposed to be shortened to a maximum of 7 working days. Even so, investors should still submit their applications early to ensure the construction schedule stays on track.
Is the VAT rate applied to construction services in 2026 8% or 10%?
According to Decree 180/2024/NĐ-CP, from January 1, 2025, through June 30, 2025, the Value Added Tax (VAT) applied to most construction activities is reduced to 8%. However, starting July 1, 2025, barring any new extension policies, the tax rate will revert to 10% in accordance with the 2024 Law on Value Added Tax.
Is constructing an office with a prefabricated steel frame more cost-effective than reinforced concrete?
Yes. Prefabricated steel frame construction allows investors to optimize and save 20% to 30% on structural construction costs compared to traditional poured concrete methods. Furthermore, steel frame buildings offer superior advantages in terms of schedule, taking only 2 to 3 months to complete the erection process, enabling businesses to bring the facility into operation and recover capital sooner.
How is the construction cost for an office building parking basement calculated?
Basements are among the most complex and expensive categories, with average construction costs ranging from VND 5,000,000 to VND 10,000,000/m² depending on landslide prevention measures such as driving Larsen sheet piles or Barrette slurry walls. In estimates and quotations, basement areas are typically calculated using a coefficient of 130% to 200% compared to standard floor space, which scales proportionally with the depth of the basement relative to the sidewalk.
What is the expected budget for an office fire protection (PCCC) system?
For standard office buildings, the cost of installing a standard water-based fire sprinkler system typically ranges from VND 21,000 to VND 25,500/m². However, if the office includes a central Data Center server room, regulations mandate the use of a clean agent fire suppression system (such as FM200, Novec 1230), which significantly drives up investment and maintenance costs. Additionally, investors must pay state fire safety design appraisal fees ranging from VND 500,000 up to a maximum of VND 150,000,000 per project.

Preparing an office construction cost estimate requires investors to have a comprehensive overview and detailed breakdown from underground structures (foundations, basements) to above-ground structures (framework, building envelope) and M&E systems. Choosing the structural solution (concrete vs. steel frame), facade design, and air conditioning configuration not only dictates the initial total investment but also directly impacts future operational expenditures (OPEX). Selecting a reputable contractor, locking in material prices early, and maximizing dry-season weather conditions will help the project reach the finish line on schedule without exceeding the contingency fund.
