In Q2/2026, the Bangkok office market did something rarely seen in recent times: it took a "pause," as not a single new office building was launched. This kept the total supply stable at 9.15 million sq.m. Meanwhile, the vacancy rate for Grade A office space in the CBD dropped to 21.9%—its lowest level in three years—signaling a positive recovery after post-COVID market turbulence.
However, average rental rates remained static at 943 THB/sq.m./month. Landlords opted to offer flexible lease terms (such as extended rent-free periods or fit-out allowances) rather than directly slashing asking rents. This clearly indicates that bargaining power remains firmly in the hands of tenants. Amid the "Flight-to-Quality" trend, aging buildings are under pressure to upgrade or risk getting left behind.
Looking ahead, a new wave of supply is on the horizon: an estimated 616,130 sq.m. of office space is scheduled for delivery between 2026 and 2031, led by the CBD and promising outer-city locations such as Late Sukhumvit, Bangna-Trad, and Phahon Yothin.
1. A Breathing Space for the Market: New Supply Slows Down
The second quarter of 2026 served as a crucial stabilization period. The Bangkok office market showed clear signs of cooling down due to zero new office project ribbon-cuttings, keeping total supply unchanged at approximately 9.15 million sq.m.
This temporary pause helped ease price war pressures. Landlords were not forced to aggressively undercut prices to compete for tenants, as newly launched buildings from the past 1–2 years have successfully pushed their occupancy rates close to full capacity.
2. Supply Distribution: Segmenting Bangkok’s Office Space
The Bangkok office market displays diverse dynamics, blending legacy buildings with modern premium developments. The market structure breaks down as follows:
|
|
Breakdown by Building Grade
|
|
|
|
Grade A: 38% of total space
|
78% of new supply over the past 10 years has been Grade A
|
Mid-Town: 2.41 million sq.m.
|
Grade B: 58% of total space
|
Over 52% of Grade B buildings are over 10 years old
|
Outer-City: 1.71 million sq.m.
|
Grade C: 4% of total space
|
Grade B holds the largest market share in Bangkok
|
"Grade B is the workhorse of the Bangkok office market and also the oldest, with over 52% exceeding 10 years of age. Grade A, meanwhile, is the market darling, accounting for 78% of all newly built space over the past decade."

3. The "Flight-to-Quality" Pressure: Aging Buildings Forced to Renovate
Tenants across Bangkok are actively driving the "Flight-to-Quality" trend—relocating from older buildings with operational constraints to state-of-the-art facilities with comprehensive amenities and more attractive lease packages.
This shift puts heavy pressure on older Grade A and Grade B buildings to retain existing tenants. Aging physical conditions combined with historically rising rents make it easier for occupiers to move out. Consequently, many legacy building owners are rushing to undertake major asset enhancements to stay competitive.
Sustainability Note: Globally, the Flight-to-Quality trend goes hand-in-hand with green building and energy efficiency standards, which top corporate occupiers prioritize. While specific metrics for Bangkok are still emerging, sustainability remains a key benchmark for future market analysis.
4. CBD Vacancies Tighten, But Landlords Still Avoid Price Wars
Driven by relocations to new buildings and tenant expansions, the Grade A CBD vacancy rate fell to 21.9% in Q2 (down from 23.3% in the previous quarter), reaching its lowest point since Q1/2023. Prime downtown office space is steadily filling up.
Average Grade A rental rates held steady at 943 THB/sq.m./month. Landlords opted to compete through incentives rather than lowering face rents, utilizing strategies such as:
- Rent-Free Periods: Move in early, defer rent payments.
- Fit-Out Allowances: Direct cash support to customize ideal workspaces.
- Flexible Terms: Adaptable lease durations for tenants seeking agility.
5. Upcoming Supply Waves and Emerging Hotspots
Looking forward to 2026–2031, Bangkok is set to welcome approximately 616,130 sq.m. of new supply. The CBD maintains its dominance due to large-scale mixed-use developments and long-term land leases.
Simultaneously, outer-city locations like Late Sukhumvit, Bangna-Trad, and Phahon Yothin are stealing the spotlight—outpacing mid-town areas as soaring downtown land costs make new office development financially challenging in core areas.
Summary Shortcuts for the Rest of 2026
- Tenant-Centric Market: High overall vacancy rates mean landlords must work hard to secure lease agreements.
- Tenants Hold the Upper Hand: Occupiers retain strong leverage over contract terms and incentive packages.
- Landlord Strategy: Asset upgrades (renovation) + attractive incentive packages beat cutting face rents.
- Short-Term Outlook: Slower new supply will keep Grade A CBD vacancy rates steady or declining. Asking rents will remain flat, with pricing pressure manifesting in concessions and incentives.
