You have secured the premises and the business direction is clear — but how to divide the space so the team actually works well is another matter. An office short of meeting rooms jams up every time visitors arrive; too many enclosed rooms waste expensive square metres. This article covers the zones a well-planned office needs in 2026, with reference area ratios so you can check your own layout.

Quick rule: a modern office needs on average 7–10 m² of floor per person (common areas included). Below 6 m²/person the space starts to feel cramped; above 12 m²/person you are usually carrying excess area.

1. Reception and guest area

The first impression for clients, candidates and partners. It does not need to be large — 10–20 m² is enough for a mid-sized office — but it must carry the brand identity correctly: logo backdrop, lighting, waiting seats. For B2B companies that host visitors often, this zone delivers the highest image return per square metre invested.

2. Staff work area — open, but with focus zones

The work area takes 50–60% of the floor. The 2026 trend is no longer pure open-plan: the common model is open space combined with focus zones — banks of team desks for collaborative work, interspersed with a few quiet, low-partition positions for tasks that need deep concentration. If you take this route, see also the principles for designing an open-plan office. Reference allowance: 4–6 m² per seat in the open area (see office design standards for area, illuminance and ventilation thresholds).

If the company works hybrid (part of the team rotates from home), consider a flexible hot-desk ratio of 60–80% of headcount instead of 1:1 — saving 15–25% of leased area.

3. Meeting rooms — and don’t forget phone booths

Every 15–20 staff should have at least 1 meeting room. A practical formula: 1 large meeting room of 8–12 seats (rectangular or oval table, presentation screen, a reliable video-conferencing setup) + 1–2 small 4-seat meeting rooms. Glass partitions let meeting rooms “borrow” daylight and a sense of space, while staying acoustically private when needed.

A near-mandatory new item since the era of online meetings: the phone booth — a soundproofed call booth for 1–2 people, 2–4 m² per booth. It is a small investment that resolves most of the noise conflicts in an open office.

4. Director / executive room

Still needed in Vietnamese companies and East Asian FDI firms, but leaner than before: 15–25 m², a desk, a filing cabinet behind the seat (both functional and aligned with the feng shui principle of “solid backing”), and a small guest sofa set. The 2026 trend is frosted glass or curtains for the executive room — keeping privacy when needed without creating a “separate class” feeling towards the team.

5. Pantry and break area

The zone that most clearly signals how much a company cares about its people — and where most informal work conversations actually happen. Minimum: a pantry counter with a sink, a fridge, a coffee machine and a few high tables. Offices from 300 m² should fully separate the lunch area so food smells do not drift into the work area — a small detail with a very large effect on the daily experience.

6. Technical support and storage

The group of spaces nobody remembers when sketching the concept but that always appears in operation: a server room/rack cabinet with its own air-conditioning, a printer and stationery area, document storage, personal lockers (especially necessary with hot-desking). Allow 5–8% of the floor area. Without this group, paper boxes and equipment will “spill” into the corridors within a few months.

7. Flexible space

A multi-purpose area of 20–40 m² for monthly town-halls, workshops and internal parties — usually placed next to the pantry with movable furniture. Fast-growing companies should also reserve a 10–15% “buffer zone” for new hires, to avoid having to refit the office after just one year.

Reference area breakdown for a 300 m² office (30–35 staff)

  • Work area: 150–170 m²
  • Meeting rooms + phone booths: 40–50 m²
  • Reception: 15–20 m²
  • Executive: 20–25 m²
  • Pantry + break: 30–40 m²
  • Support + storage: 20–25 m²

When planning for real, the single most worthwhile step is a test-fit: placing all of the zones above onto the actual floor plate to see whether they “fit” before you sign the lease. This is what AIC typically does with clients at the pre-design stage under the design-build model — together with a BOQ estimate within 4 working hours, so you know immediately what that layout costs, instead of discovering a budget overrun after the drawings are done.

Frequently asked questions

What zones does a small 100 m² office need at minimum?

Four zones are non-negotiable: the work area (~55–60 m²), 1 glass-walled meeting room of 6–8 seats, a small pantry counter, and a reception corner combined with the waiting area. The director room can be replaced by a meeting room that doubles as a private office when needed.

How many square metres of office does one employee need?

The common 2026 benchmark is 7–10 m² per person on total leased area (common areas included), of which the actual workstation takes 4–6 m². Hybrid companies applying hot desks can go down to 5–7 m² per headcount.

Roughly how much does fitting out these zones cost?

In HCMC in 2026, turnkey office fit-out typically falls around 4–8M VND/m² for a basic standard and 8–14M VND/m² for a corporate standard — varying with the ceiling system, partitions, MEP and loose furniture. An exact figure only exists after an itemised quantity take-off on your specific floor plan.
