An open-plan office is a layout that removes hard walls and partitions between departments, letting staff share a common working floor — usually desk clusters side by side in a large area. Its biggest advantage is increased interaction, faster idea exchange and more efficient use of space than the traditional partitioned style. But for the model to truly work, two inherent weaknesses must be solved: noise and the need for privacy. Here are the benefits and correct design principles.

What is open plan

Unlike the traditional style — each department working separately, divided by walls and corridors — open plan lets staff share one common floor. Desks sit side by side or in clusters, with low walls or none, creating a seamless feel that is easy to move around. See also the general pros and cons of open space in architecture and interiors.

Benefits of an open-plan office

  • Connection within teams: removing physical barriers eases communication, speeds up idea exchange and builds team spirit.
  • Connection between departments: shared areas such as lounges, group meeting spots and break corners encourage departments to meet, reducing a sense of separation.
  • Flexibility in work: staff choose the seat that suits the task, easily change positions by project, creating a dynamic environment.
  • Space optimisation: one shared area can serve multiple purposes — meetings, training, internal events — instead of a rarely-used private room, saving cost and boosting versatility.

How to design an open plan successfully

Open plan easily fails if you just “knock the walls down”. Two issues must be solved:

Acoustics and noise

This is weakness number one. Invest in soundproofing and acoustic treatment: felt or mineral-wool panels for walls and half-height partitions, floor carpet to reduce footsteps, phone booths for private calls. Also provide quiet zones for focus-heavy work.

Balancing shared and private space

Going fully open does not mean abandoning all privacy. Keep enclosed meeting rooms, quiet corners and personal space so staff have room for independent thinking. Frosted glass or movable partitions are good tools for soft zoning while keeping the airy feel.

One point of contact to open up correctly

The hard part of open plan lies in the “invisible” work: acoustic treatment, fresh-air supply, even lighting, tidy power and network runs for desk clusters. These only succeed when design and construction coordinate closely. The single-point model consolidates design, M&E and finishing in one place to avoid technical conflict.

AIC follows a single-point design-build model, with over 10 years in the trade (predecessor Nhan Viet from 2016, AIC established in 2019) and two in-house workshops (1,200 m² and 600 m²). From a floor plan, AIC builds a BOQ estimate in about 4 hours; projects are handed over with a warranty of up to 24 months and a periodic maintenance schedule.

Frequently asked questions

Is an open-plan office suitable for every business?

No. The model suits startups and creative teams that need a lot of exchange. Businesses with many functions needing quiet or confidentiality (legal, finance) should combine: open for shared areas, partitioned for specialised departments — see the common office layouts to balance the ratio.

How to reduce noise in an open office?

Combine multiple layers: acoustic panels on walls and half-partitions, floor carpet, phone booths for calls, and separate quiet zones. Do not rely on a single solution — effectiveness comes from handling multiple noise sources together.

Is an open plan more cost-effective?

It usually saves on partition costs and uses space better, but needs extra investment in acoustics and flexible furniture. Total cost depends on the level of acoustic treatment and the number of private zones you keep.
