Commercial office fitout design and planning by Stemar Group

Office Fitout Design That Gets Built on Budget

One team from first sketch to final fitout. Every design decision made with buildability and budget in mind.

A Clear Process from Design to Delivery

Every stage includes clear deliverables and approval points. So you know exactly what you're getting before anything is built.

Stage 1

Site Assessment

Before any design begins, we assess what already exists on site. This ensures your design is based on real conditions, not assumptions.

  • Site photos and measurements of every area
  • Existing services map showing electrical, data, plumbing, and HVAC locations
  • Structural and lease constraint summary
  • Initial feasibility notes on your brief
Stage 2

Space Planning

With a clear understanding of your site, we design a layout around how your team actually works. This stage focuses on function, flow, and making the best use of your space.

  • Space plan drawings showing zones, circulation paths, and furniture placement
  • Team adjacency and workflow diagram
  • Client approval point: layout sign-off before moving to visualisation
Stage 3

3D Visualisation

We bring your design to life in 3D so you can see how the space will actually look and feel. This allows you to make confident decisions early, before changes become costly.

  • 3D walkthrough images of key areas
  • Colour and material direction visible in context
  • Client approval point: visual sign-off before material selection
Stage 4

Material Selection

With the design finalised, we guide you through selecting finishes, materials, and furniture. Every choice is made with cost, durability, and long-term use in mind.

  • Physical material samples for review
  • Specification schedule with product codes, suppliers, and pricing
  • Client approval point: material and finish sign-off
Stage 5

Compliance Review

Before construction begins, we review your design against all relevant compliance requirements. This ensures everything is approved and ready, avoiding delays later in the process.

  • Compliance checklist against relevant council requirements
  • Fire safety and accessibility review
  • Compliance sign-off confirming the design meets approval pathway requirements
Stage 6

Construction Documentation

We turn your approved design into detailed documentation ready for construction. Everything is clearly defined, so there’s no confusion, no guesswork, and no gaps between design and build.

  • Construction-ready drawing set including floor plans, elevations, and sections
  • Electrical, data, and mechanical layout drawings
  • Detailed specification schedule referenced to approved materials
  • Scope of works document for pricing

Design is What Controls Your Fitout Cost

Design isn’t an added cost, it’s what controls your budget. Most cost overruns don’t happen during construction. They happen during design. When design decisions are made properly, your fixed-price quote holds without surprises .

Material Specifications

Stemar's designers present finish options at multiple price points so you make informed trade-offs. A low-range to high-range swap across a 500sqm office is a significant line item either way.

Layout Complexity

More partitioned rooms means more walls, doors, circuits, and HVAC zones. Open plan cuts those costs but needs acoustic treatment. Your layout is a cost decision as much as a design one.

Services Relocation

Moving a kitchen, bathroom, or server room drags plumbing, electrical, and data runs with it. Designs that work with existing service locations save thousands.

Compliance Alignment

Designs that ignore council requirements get redesigned at your expense. Fire safety, accessibility, and ventilation built in from the start avoid that cycle entirely.

Modern office fitout design in a Western Sydney commercial building

A-Grade Workspace Feel Without the A-Grade Lease

Businesses are upgrading workspace quality to attract talent and improve performance. You don’t need an A-grade building to achieve that. A well-designed fitout can transform a B-grade space into a high-performing workplace at a fraction of the cost.

For mid-sized businesses, this is a clear opportunity. Lower lease costs combined with a quality fitout means better space without overpaying.

Strategic Materials

Premium look without premium cost through smart finish selection.

Lighting Design

Transforms how a space feels without structural changes.

Acoustic Treatment

Open spaces that stay functional without excess noise.

Avoid Delays with Approvals Handled Early

Ignoring council requirements during design leads to costly delays later. We build compliance into the design process, so approvals don’t slow your project down

Commercial fitouts in NSW follow two approval pathways. A Development Application (DA) is assessed by council and takes longer. A Complying Development Certificate (CDC) is assessed by a private certifier and moves faster. The right pathway depends on your scope, building classification, and location. Stemar identifies the correct pathway during design, not after documentation is complete.

Deep Western Sydney Council Knowledge

Based in Wetherill Park, Stemar works regularly with Parramatta, Penrith, Liverpool, and Fairfield councils. Requirements are understood before design begins.

Fire Safety Requirements That Change Layouts

Fire compartmentation, egress, and sprinkler coverage can affect layout. These are addressed early to avoid redesign later.

Accessibility Compliance Built In

Corridor widths, clearances, and accessible amenities are built into the layout from the start to meet requirements.

Parking and Tenancy Change Conditions

Tenancy changes can trigger parking and planning conditions. These are identified early to prevent delays during construction.

Office Layout isn’t One-Size-Fits-All

Your layout should reflect how your team works, not design trends. Stemar Group design around your operations, not the other way around.

01

Open Plan

Open plan layouts work well for collaborative teams and flexible workflows, with fewer walls reducing overall build costs. However, they rely heavily on proper acoustic treatment to prevent noise from affecting productivity. When designed correctly, they create an open, connected workspace that supports team interaction without compromising comfort .

02

Partitioned

Partitioned layouts suit businesses that require focused, private, or confidential work environments. While they involve higher construction costs due to additional walls, services, and separate zones, they provide better acoustic control and allow each area to function independently. This makes them ideal for teams handling sensitive work or frequent client interactions

03

Hybrid

Hybrid layouts combine open collaboration areas with quieter, more focused zones within the same space. This approach supports different work styles and is often the most practical solution for modern workplaces. By balancing cost, flexibility, and functionality, hybrid designs create a workspace that adapts to how teams actually operate day to day

Sometimes a fitout isn’t the right solution

Some spaces have underlying issues that design alone won’t fix.
Water damage, outdated services, or ageing infrastructure can turn a fitout into a temporary solution, not a long-term one.
In these cases, refurbishment is often the better option. We’ll tell you which path makes sense, before you commit to design.

What to Know Before Designing Your Office Fitout

How long does the office fitout design phase take?

Typically 4 to 8 weeks, depending on size and complexity. A single-floor office of 200 to 400sqm is closer to four weeks, while larger or more complex projects take longer.

Can I make changes after the design is finalised?

Yes. Changes during design are simple. Changes during construction affect cost, timing, and compliance. That is why each stage includes a sign-off point.

Do I need to replace all my existing furniture?

No. Existing furniture is assessed during space planning. Items that work are retained, and anything unsuitable is flagged with replacement options.

Will construction disrupt our daily operations?

Minimally, with proper planning. Work can be staged and scheduled after hours so your team continues operating in unaffected areas.

What if we only need a partial redesign?

That is common. Some projects focus on specific areas like reception or meeting rooms. Scope is defined during the design consultation.

Do you only work in Western Sydney?

No. Stemar delivers projects across Sydney, with deep knowledge of Western Sydney councils, suppliers, and building conditions.

Start With a Design Consultation

We visit your space, understand how your team works, and outline an initial direction. You leave with a clear view of what your fitout involves, whether you proceed or not. No obligation, no hard sell. You speak directly with the people delivering the project.
