Rental Guide
True Cost of Renting Office Space
What Most Tenants Don't Realise — How Much Extra?
The listed rent is just the starting point. You'll also pay for A/C, electricity, parking, and overtime — adding 20–40% on top.
💡 Know This First: True Costs Are 20–40% Higher Than Base Rent
The rent you see in listings is for the bare floor space. It does not include electricity, A/C, parking, or overtime A/C charges — which add 20–40% per month on top of base rent.
Cost Components to Budget For
⚡ Electricity & Air-Conditioning (The Most Overlooked)
⚠ Many tenants assume central A/C is included in rent — it's not! Only ~10% of Bangkok buildings include A/C in the base rent.
❄ Central A/C
~฿50
per sqm / month (8 hrs/day, 5 days/week)
Building controls temperature; A/C operates during office hours only.
🌀 Split-Type A/C
~฿100
per sqm / month (8 hrs/day, 5 days/week)
Tenant controls temperature independently; higher electricity cost but flexible for overtime work.
Note: These figures exclude lighting and plug-in device electricity (computers, kettles, etc.), which are billed separately.
🚗 Parking
฿1,500–4,500
per car / month
CBD locations cost more; varies by building.
🌙 Overtime A/C
฿150–500
per hour / zone
A/C after office hours; must book in advance with building.
🔐 Security Deposit
3 Months
of rent, paid upfront
Refunded at lease end in original condition.
🔨 Fit-out Cost
฿2,000–8,000
per sqm (spec-dependent)
Partitions, electrical, furniture — one-time cost.
