Open plan office fitout with acoustic treatment and hybrid zoning by Stemar Group

Open Plan Office Fitouts in Sydney

We design open plan offices with acoustic treatment, hybrid zoning, and quiet areas built in from day one, not desks in a row and hope for the best.

What Makes Open Plan Office Design Actually Work

Open plan office design fails when noise is ignored. It works when acoustic treatment and zoning are part of the plan from the first sketch, not added after complaints start rolling in.

Unmanaged noise in open plan offices directly impacts productivity and wellbeing. The National Construction Code recognises this. Acoustic treatment is not optional. It is a design requirement. As part of a commercial office fitout, we coordinate all trades under one project manager so acoustic strategy is built into the design stage, not patched in after complaints start.

Acoustic Ceiling and Wall Panels

We install ceiling panels and wall absorbers to reduce noise across open offices. These are planned during design and installed before furniture, not added later.

Strategic Zone Separation

Collaboration areas are separated from focused work zones. Layout, desks, and storage are arranged to reduce noise without adding walls.

Enclosed Quiet Rooms and Phone Booths

Open plans include enclosed spaces for calls, meetings, and focused work. Acoustic treatment ensures privacy without leaving the office floor.

Layout Orientation and Furniture Placement

We position workstations and use joinery, plants, and soft furnishings to control sound. Smart layout replaces the need for artificial noise solutions.

Open Plan or Private Offices? You Can Have Both

You do not have to choose between open plan and private offices. Modern open plan combines open work zones with enclosed spaces for specific tasks. This is how it works in practice.

Open Collaborative Zone

Grouped workstations with acoustic panels and soft furnishings that absorb noise. Designed for teams that communicate frequently and benefit from proximity.

Enclosed Meeting Room

Fully enclosed rooms with acoustic-rated walls and doors for meetings, calls, and confidential discussions. Sized for small teams with independent ventilation.

Focus Pod or Quiet Room

Enclosed pods for deep work, calls, or tasks that require concentration. Acoustic lining reduces noise from the open office.

Breakout and Social Zone

Informal areas with lounge seating or standing tables. Positioned away from focus zones to keep noise contained.

Why Open Plan Office Fitouts Cost Less

Open plan fitouts cost less per square metre than partitioned offices. This is a structural cost difference, not a quality compromise. Here is where the savings come from and where the money goes instead.

01

Fewer Walls and Doors

Internal walls are one of the biggest cost drivers in partitioned fitouts. Open plan removes most of that cost upfront.

  • No stud framing for multiple internal walls
  • No plasterboard, stopping, or painting per room
  • No door frames, doors, or hardware for each space
02

Simpler HVAC Zoning

Partitioned offices require separate air conditioning zones. Open plan reduces zones and lowers mechanical costs.

  • Fewer duct runs and diffuser points
  • Reduced controls and thermostat hardware
  • Lower commissioning and balancing time
03

Budget Redirected to Quality

Savings from construction go into finishes, furniture, and acoustics. The result is a more polished workspace.

  • Higher-grade flooring and ceiling finishes
  • Quality acoustic panels and soft furnishings
  • Better workstation furniture and seating
04

Fixed-Price Certainty From Stemar

We provide clear fixed pricing with no surprises. You know the cost before work begins.

  • Detailed scope before construction starts
  • No provisional sums or hidden allowances
  • Changes only if you request them

Open plan office fitout compliance review and council approval documentation in Sydney

Compliance Your Open Plan Fitout Needs to Get Right

The National Construction Code requires clear emergency egress planning and fire compartment checks for commercial office layouts.

Removing internal walls in an open plan conversion can change the fire compartment structure of a building. Get that wrong and you face rework, stop-work orders, or failed inspections.

We account for compliance from the design stage. Emergency egress paths are planned before a single wall comes down. Fire separation measures are addressed as part of the scope, not discovered mid-project.

Minimum workspace dimensions per employee are checked in every layout we deliver. Our team is based in Wetherill Park and knows how Sydney approvals work because we manage them every week.

We have delivered commercial fitout projects across Sydney for over two decades. Council approvals do not stall your project when the team managing them knows the process inside out.

Emergency Egress

Paths planned before demolition begins, fire compartmentalisation assessed and reconfigured.

NCC Compliance

Minimum workspace dimensions per employee verified against National Construction Code standards.

Council Approvals

Documentation prepared and submitted by our team, backed by 20 years of Western Sydney council relationships.

Open Plan Office Fitouts We’ve Delivered

Every open plan fitout we deliver is designed around how each team works, not a template. These projects show how acoustic treatment, zoning, and layout come together in real workplaces.

Logistics Company - Open Plan Conversion

Logistics Company - Open Plan Conversion

A 400sqm partitioned office with 14 enclosed rooms converted to an open plan layout with three acoustic zones, two enclosed meeting rooms, and a focus pod. Ceiling-mounted acoustic panels and strategic desk orientation delivered a 65% drop in reported noise complaints versus the previous layout. The open plan office fitout was completed in six weeks using staged delivery. The team worked from one end of the office while we converted the other.

Open Plan Office Fitout FAQs

How long does an open plan office fitout take?

4 to 8 weeks for most 300 to 500 square metre spaces in Sydney. Open plan fitouts are faster than partitioned builds because there are fewer walls and doors to construct. The exact timeframe depends on whether you are converting an existing layout or fitting out an empty shell. We provide a timeline estimate at the consultation stage and can schedule work around your operations, including after-hours and weekends.

How do I get an open plan fitout quote?

Book a consultation. We visit your site, assess the space, discuss your team's needs and layout options, and provide a fixed-price quote. No obligation. No call centre. You speak with a principal from the first conversation. We move fast on quotes because we do not route them through layers of approvals.

Can I convert my partitioned office to open plan without relocating my team?

In most cases, yes. We use staged delivery to convert your office in sections. Your team continues working in one area while we strip and rebuild another. Noisy trades like demolition and concrete cutting are scheduled for after hours when needed. The goal is zero lost working days for your business.

What if open plan does not suit some of my team?

That is why we design hybrid layouts. Open zones handle collaborative work. Enclosed meeting rooms and focus pods handle confidential conversations and deep concentration tasks. The layout is designed around how your team operates, not around a single layout philosophy. Every role gets the environment it needs.

Do I need council approval to remove internal office walls?

It depends on the building and the walls. Load-bearing walls require structural engineering assessment and approval. Removing walls that form part of a fire compartment triggers reassessment under the National Construction Code. We handle all of this as part of the design and approval process so you do not face surprises mid-project.

Is open plan suitable for every type of business?

Not always. If your work involves frequent confidential conversations, sensitive client data, or highly focused individual tasks for most of the day, a partitioned or hybrid layout may serve your team better. We will tell you that at the consultation stage rather than push a layout that does not fit.

Book a Consultation to Plan Your Open Office Layout

We visit your site, assess the space, and discuss your team's needs. You get layout options and a fixed-price quote with no obligation. The conversation is with a principal, not a sales rep. No pressure, no follow-up calls you did not ask for. One meeting to find out what your space could look like and what it would cost.
