Bangkok Office Market Map: Rama 9 Holds Firm as Bangna Vacancies Rise

Bangkok’s office market in the second quarter of 2026 shows that rising asking rents do not necessarily signal stronger leasing demand in every district. With more options available, occupiers are placing greater emphasis on value, building quality, accessibility and flexible space rather than choosing an office based on its address alone.

Knight Frank data reported by Krungthep Turakij shows that Phetchaburi–Rama 9–Ratchada recorded an occupancy rate of 82%. In contrast, average asking rents in Bangna–Srinakarin increased by 8.4% quarter on quarter, while occupancy fell to 67%. The divergence highlights why office-market performance must be assessed through rents, vacancies, building quality and local demand together.

Bangkok’s Office Market Is Shifting from Location to Value

Prime business addresses traditionally enjoyed a clear advantage, but the arrival of new, higher-quality supply has given occupiers more choices. Buildings with convenient transport connections, modern systems, energy efficiency and adaptable floor plans are better positioned to retain tenants.

The district-level figures also demonstrate that asking rents and occupancy can move in opposite directions. Owners and investors should therefore look beyond headline rents and examine actual vacancies, building age, leasing incentives, new contracts and the future supply pipeline.

Office-Market Performance by District

Ploenchit–Chidlom–Wireless Road

Average asking rent reached approximately THB 1,075 per square metre per month, up 0.3% quarter on quarter. Occupancy also increased by 0.3 percentage points to 75%, supported by the district’s premium image, mass-transit access and surrounding amenities.

Nana–Asoke–Phrom Phong

Average asking rent declined by 1.1% to around THB 898 per square metre per month, while occupancy rose by 0.7 percentage points to 80%. This suggests that competitive pricing, combined with strong connectivity and a dense mix of business and lifestyle activity, continues to attract occupiers.

Silom–Sathorn–Rama IV

Average asking rent increased by 3% to approximately THB 1,018 per square metre per month, but occupancy fell by 1.4 percentage points to 74%. Investors should distinguish between the rent landlords advertise and the effective price and terms tenants are prepared to accept.

Phetchaburi–Rama 9–Ratchada

Average asking rent edged down by 0.4% to around THB 728 per square metre per month. Occupancy stood at 82%, still the highest among the districts reported despite a 1.6-percentage-point decline. Its advantages include rents below the CBD average, MRT access and a well-established mix of offices, residential projects and retail facilities.

Phahonyothin–Vibhavadi

Average asking rent rose by 0.9% to approximately THB 723 per square metre per month, while occupancy increased by 0.3 percentage points to 75%. Compared with several other submarkets, the district showed relatively balanced growth.

Bangna–Srinakarin

Average asking rent increased sharply by 8.4% to approximately THB 688 per square metre per month, while occupancy dropped by 9.3 percentage points to 67%. Newer buildings with higher rents entering the market may have lifted the average, so the increase should not automatically be read as equivalent growth in tenant demand.

What the Office Figures May Mean for Residential Property

Rama 9–Ratchada Retains a Strong Employment Base

Office occupancy of 82% confirms that Rama 9–Ratchada remains an important employment district, potentially supporting weekday activity and demand for homes near mass transit. However, the 1.6-percentage-point decline means condominium investors should also examine achieved residential rents, competing listings and the time needed to secure a tenant instead of relying on office data alone.

Asoke–Phrom Phong Benefits from Connectivity and Mixed Uses

The rise in occupancy to 80%, despite a reduction in asking rents, suggests that occupiers continue to favour areas with convenient transport and a combination of offices, homes, hotels and retail. This can help sustain residential rental demand, although prices and yields still need to be evaluated project by project.

Bangna Retains Long-Term Potential, but Its Office Market Needs Time

Lower office occupancy should not be interpreted as weakness across Bangna’s entire residential market. The wider area continues to benefit from Suvarnabhumi Airport, major shopping centres, logistics, industrial estates and a growing housing base. Nevertheless, investors in offices and commercial property should account carefully for new supply and use conservative occupancy assumptions.

Office Buildings Must Sell More Than Floor Area

Competition in the modern office market extends beyond price and address. Buildings that retain occupiers need to perform in at least four areas: accessibility, building quality and efficiency, flexibility of space and overall value for money.

For residential buyers and investors, office-market trends offer useful evidence about employment clusters and local economic activity. They should still be considered alongside residential data such as achieved condominium rents, resale prices, vacant listings and the pipeline of new projects.

Conclusion

Bangkok’s office market in Q2 2026 cannot be reduced to a simple contest between strong CBD locations and weaker non-CBD districts. Competition increasingly takes place at building level. Rama 9–Ratchada maintains high occupancy, Asoke–Phrom Phong has responded well to more competitive pricing, while Bangna–Srinakarin requires closer attention to vacancies and new supply despite its higher average asking rent.

Anyone buying, selling or leasing property near Bangkok’s employment centres should compare projects and buildings individually to assess genuine demand, competition and potential returns more accurately.
