A private office for a 5–10 person team costs LKR 120,000–250,000 per month all-inclusive in Colombo’s suburbs, and LKR 400,000–800,000 in the central business district, as of 2026. Per person, that’s LKR 15,000–30,000 monthly in the suburbs — often less than the same team would pay for individual hot desks. For startups moving out of homes, cafés or a cramped first office, here’s exactly how to budget for the 5–10 seat stage.
The 5–10 person stage is different
At 1–3 people, hot desks or a home office work fine. At 15+, you can justify traditional space. The 5–10 range is the awkward middle where most startups make their first real workspace decision — usually right after a funding round, a big client win, or the moment daily standups in a café stop being charming. The good news: this is exactly the team size the flexible-office market prices most competitively, because a whole room’s economics finally beat per-desk pricing.
What you’ll pay in 2026
| Location | 5–6 seat office | 8–10 seat office | Per-seat range |
|---|---|---|---|
| Colombo suburbs (Kottawa, Maharagama, Nugegoda) | LKR 120,000–180,000/mo | LKR 160,000–250,000/mo | LKR 16,000–30,000 |
| Colombo 4–7 | LKR 250,000–400,000/mo | LKR 350,000–550,000/mo | LKR 35,000–70,000 |
| Colombo 1–3 (CBD) | LKR 400,000–600,000/mo | LKR 500,000–800,000/mo | LKR 50,000–100,000 |

The startup budgeting framework
Rule 1: Budget per seat, decide per room. Work out what per-person cost your runway supports (a common startup benchmark: workspace should stay under 5–8% of monthly operating costs). Then find the room that fits — remembering rooms are priced as units, so a 8-seat room for a 6-person team costs slightly more per current head but buys you two hires of headroom.
Rule 2: Rent for month 9, not month 1. The most expensive workspace mistake at this stage is taking a 5-seat room, hiring three people, and relocating within a year. If your hiring plan says 9 people by year-end, take the 10-seat room now or choose a provider with a bigger room you can move into. Moving costs are never just the truck — they’re a lost week of productivity and an address change everywhere.
Rule 3: Count the all-in number. A traditional “cheap” office at LKR 100,000/month for this team size becomes LKR 200,000+ once you add fit-out amortisation, electricity for AC, business fibre, cleaning and a 6-month deposit’s opportunity cost. The all-inclusive quote that looked more expensive is usually the cheaper total. (Full comparison → Post 4.)
Rule 4: Protect the runway, not the ego. A CBD address at LKR 600,000/month vs a suburban office at LKR 180,000/month is a LKR 5M annual difference — roughly two mid-level engineering salaries in 2026. Investors are far more impressed by hires than by lobbies.
What a 5–10 seat office must include
Non-negotiables for a working startup at this size:
- Fibre internet with a redundant second line — a dev team dead for a day costs more than a month’s rent
- Backup power with fast switchover (generator/UPS), including AC on backup if possible
- Meeting room access — you’ll need it weekly for clients, interviews and sprint planning; check if hours are included
- 24/7 access — startups don’t work office hours, especially with overseas clients across time zones
- Room to grow — a documented path to a bigger room at the same address
- Parking for the 2–4 team members who drive
- A lockable door and separate network if you handle client data — increasingly a due-diligence question from enterprise customers
The per-seat maths that surprises founders
Take a 6-person team in the suburbs:
- 6 hot desks at LKR 20,000 = LKR 120,000/month, open-plan, no privacy
- 6-seat private office = LKR 120,000–180,000/month, lockable room, your own culture, calls at your desk
For roughly the same money — or a 20–30% premium at most — the team gets a real office. This is why the 5–10 person private office has become the default startup choice in Sri Lanka’s flexible workspace market: the open-plan discount simply isn’t big enough at this headcount.
When to graduate to your own lease
The flexible private office stops being optimal somewhere around 15–20 people, when per-seat pricing of traditional space (even with fit-out) starts winning and you want full control of the environment. Until then, every rupee locked in deposits and furniture is a rupee not funding growth. Plan the graduation — don’t rush it.

Frequently asked questions
How much office space does a 10-person team need? Roughly 700–1,200 sq ft in a traditional layout; in a flexible workspace you rent by seat count instead, which is simpler — a “10-seat private office.”
What does an office for a startup cost in Colombo? In the suburbs, LKR 120,000–250,000/month all-inclusive for 5–10 people. Central Colombo runs 2–4× that.
Should a startup sign a long office lease? Rarely before 15+ staff. Month-to-month or 6–12 month flexible terms match the uncertainty of startup hiring plans.
Can we brand our private office? Yes — most providers allow signage on your door and personalisation inside your room.
