What Is a Commercial Fit Out?
A commercial fit-out refers to the process of customising an interior space to meet the operational needs of a business. It transforms a bare or partially completed property into a fully functional environment ready for use by employees, clients, or customers. Fit-outs vary in complexity, from Shell and Core spaces (just structural elements) to CAT A fit-outs (basic installations like ceilings, lighting, and HVAC), through to CAT B fit-outs, which include partition walls, branding, furniture, and finishes. Some companies also opt for turnkey solutions, where the space is delivered completely ready for use. Each level impacts your cost, timeframe, and design control.
Average Cost of Commercial Fit Outs in Sydney (2025)
Fit-out costs in Sydney range widely, depending on the quality, size, and complexity of the space. Here’s a breakdown of average prices per square metre:
| Fit Out Type | Average Cost (per sqm) | What’s Included |
| Basic Fit Out | $800-$1200m2 | Open-plan layout, basic lighting and flooring |
| Mid-Range Fit Out | $1200-$1800/m2 | Partitions, breakout areas, standard joinery |
| High-End Fit Out | $1800-$2500+/m2 | Premium finishes, bespoke joinery, integrated tech |
These price bands are influenced by a number of variables, including location (CBD vs. fringe suburbs), the existing condition of the premises, the services required (electrical, data, HVAC), and the level of customisation in your design. For example, a corporate headquarters in the CBD requiring detailed joinery and integrated AV systems will cost significantly more than a simple open-plan space in Parramatta.
Cost Breakdown: What’s Included in a Fit Out?
To better understand where your money goes, it’s helpful to break the fit-out project into key components:
Design and Planning
This includes early consultations, site surveys, layout planning, and concept development. Designers and project managers collaborate to ensure the space aligns with your brand, meets safety regulations, and optimises workflow. Approval processes with councils or landlords may also fall under this phase.
Construction Works
Here’s where the vision comes to life. Construction work includes internal walls, partitions, ceilings, painting, flooring, and all fixed elements. High-end fit-outs may also involve acoustic treatments, custom carpentry, or specialised finishes like glass panelling and timber cladding.
Services
Fit-outs typically require new or upgraded services: electrical, data cabling, HVAC systems, plumbing, and fire protection. These must meet the stringent Building Code of Australia (BCA) and local compliance standards, especially important in commercial tenancies.
Furniture and Fixtures
Workstations, ergonomic chairs, collaborative furniture, lighting fixtures, break-out space seating, and AV installations are typically provided and installed. Businesses often underestimate this cost area, but furniture alone can account for 10-20% of total spend.
Project Management
Professional fit-out companies provide end-to-end project management to coordinate trades, manage timelines, and ensure that everything is delivered to specification. This service is crucial for preventing cost overruns and delays, particularly in live office environments.
Hidden Costs to Watch Out For
Unexpected costs can creep in if you’re not working with a transparent and experienced contractor. One common pitfall is make-good obligations—the requirement to return the leased space to its original condition at the end of your tenancy. If you’re moving out, this can significantly increase your budget.
Other hidden costs include:
- Building access restrictions (e.g. only night-time work allowed)
- Permit and fire safety approval fees
- Delays due to supply chain shortages
- Mandatory upgrades to old base building services
A clear, itemised proposal and early consultation with your contractor can prevent most of these issues.
Cost-Saving Tips for Your Sydney Fit Out
- Choose a design and construct firm – Firms like Stemar Group manage both design and delivery, reducing miscommunication and rework.
- Reuse where possible – Salvaging existing partitions, flooring, or HVAC systems can significantly cut costs.
- Modular and flat-pack furniture – These options are often cheaper and easier to relocate in the future.
- Stage your fit-out – If your budget is tight, roll out your fit-out in phases across departments or floors.
- Choose energy-efficient solutions – LED lighting, motion sensors, and zoned HVAC systems reduce long-term operational costs and may qualify for rebates.
