Three storeys is the most common choice for families in Hai Phong and the former Hai Duong area (now part of Hai Phong city): enough rooms for two or three generations on a 4–6 m street-front plot, at a manageable budget. This article answers the first question every homeowner asks, how much does a 3-storey house cost?, using exactly the rates in the HICONIQUE × PQT building cost estimator.
Quick answer
For a 3-storey townhouse with 60 m² per floor (a 5 × 12 m plot), flat concrete roof, no basement:
- Converted construction area: 240 m²
- Turnkey build (structure + finishing), standard tier: about VND 1.44–1.85 billion, i.e. VND 6.0–7.7 million per converted m²
- Construction time: about 4–8 months
Open the estimator with this example, then change the area and number of floors to match your plot.
How construction area is calculated
Vietnamese contractors price on a converted construction area, because foundations, roofs and basements also consume materials and labour:
| Item | Area factor |
|---|---|
| Each floor | 100% |
| Foundation | 50% of ground-floor area |
| Concrete roof | 50% |
| Tiled roof | 70% |
| Basement | 150% |
2026 reference rates (standard tier)
| Item | Reference rate |
|---|---|
| Structural works | VND 3.6–4.2 million/m² |
| Finishing works | VND 2.4–3.5 million/m² |
| Architectural design | VND 150,000–250,000/m² |
| Interior design (usable area) | VND 200,000–350,000/m² |
| Interior fit-out (usable area) | VND 3.5–6 million/m² |
Example: 60 m² per floor, 3 storeys (240 m² converted)
| Tier | Structure | Finishing | Total |
|---|---|---|---|
| Standard | VND 864M–1,008M | VND 576M–840M | VND 1.44–1.85B |
| Premium | VND 907M–1,058M | VND 778M–1,134M | VND 1.68–2.19B |
| Luxury | VND 950M–1,109M | VND 1,094M–1,596M | VND 2.04–2.70B |
Adding architectural and interior design plus interior fit-out (full design & build), the standard tier comes to about VND 2.14–3.05 billion over 6–11 months. With a basement the converted area rises to 330 m² and the turnkey build to about VND 1.98–2.54 billion.
