A commercial fitout is the process of turning an empty shell or existing workspace into a functional environment designed around how your business actually operates.
It sits at the intersection of design, construction and services. A typical fitout can include planning, design, demolition, new walls and ceilings, services installation, joinery, finishes and compliance, all coordinated so a tenancy is ready for staff and customers to use.
For business owners, tenants, developers and asset managers, understanding what a fitout is and how it’s delivered is the difference between a smooth project and a disruptive, costly one.
This guide explains what a commercial fitout involves, how it differs from refurbishments and renovations, the typical process, the main cost drivers, and why working with an experienced commercial fitout contractor matters.

What is a commercial fitout?
A commercial fitout is the work required to convert a base-building space into a ready-to-occupy space for a specific business.
In most commercial leases, the landlord delivers the base build – structure, core services and common areas – while the tenant is responsible for shaping the inside of the tenancy. The fitout is the step that turns that bare space into a workplace or trading environment that actually functions.
In practice, that means deciding how people move through the tenancy, where work happens, where customers are greeted and how services support day-to-day operations. An office fitout might include reception, electrical, and data systems. A retail fitout might establish the shopfront, sales floor, back-of-house, and storage in line with both brand standards and operational needs.
Seen this way, a fitout is not just an interior makeover. It is a coordinated construction project that links design intent, building services, and compliance to ensure the tenancy is safe, functional, and aligned with how the business works.
Types of commercial fitouts
While every project is different, most commercial fitouts fall into a few broad categories.
Office fitouts
Office fitouts focus on creating effective workplaces. They can include:
- Workstations and collaboration zones
- Meeting and focus rooms
- Reception and client areas
- Staff amenities and kitchens
Projects range from light cosmetic refreshes through to full replanning of floorplates in multi-storey buildings.
Retail fitouts
Retail fitouts are about how customers experience a brand in-store. They typically cover:
- Shopfronts and entries
- Sales floors and merchandising zones
- Point of sale areas
- Back-of-house storage and preparation areas
In shopping centres, retail fitouts also need to align with the centre’s design criteria and trading requirements set out in the landlord’s guidelines.
Hospitality fitouts
Hospitality fitouts for cafés, restaurants and bars bring together:
- Customer seating and service areas
- Bars, servery counters and pass zones
- Commercial kitchens and back of house
- Acoustic and services considerations
These projects have additional demands around kitchen services, exhaust, hygiene and workflow.
Healthcare, education and industrial offices
Other common categories include:
- Healthcare fitouts for clinics and medical suites
- Education spaces such as training rooms or learning hubs
- Offices within industrial buildings, distribution centres or logistics hubs
Each of these has specific operational, compliance and servicing needs that shape the fitout.
What does a fitout include?
The exact contents of a commercial fitout depend on the building, the tenancy and the scope agreed with the landlord. Most projects, however, involve a similar mix of components.
A typical commercial fitout can include:
- Demolition and strip outs: Removing existing partitions, ceilings, floor finishes and services that are no longer needed
- Partition walls: Building new rooms, offices, meeting spaces and storage areas
- Flooring: Carpet, vinyl, tiles or other floor finishes suited to the use
- Ceilings: Suspended ceilings, bulkheads and feature elements
- Lighting: General lighting, task lighting and feature fittings
- Electrical: Power, data, small power to workstations, switchboards and controls
- HVAC: Air conditioning modifications, ductwork, diffusers and controls to match the new layout
- Plumbing: Sinks, amenities, kitchenettes or specialist plumbing where required
- Joinery: Reception counters, kitchen joinery, storage, retail fixtures and custom furniture elements
- Finishes: Paint, wall linings, feature walls, graphics and branding
- Furniture coordination: Where included, coordinating loose furniture, workstations and seating with the built fitout
In live environments, these elements also have to be sequenced carefully so neighbours can keep trading and building operations continue safely.
Fitout vs refurbishment vs renovation
‘Fitout’, ‘refurbishment’ and ‘renovation’ are often used interchangeably, but they are not the same.
- A fitout usually refers to preparing a base-building space for a particular tenant. It is about layouts, services and finishes that support a specific business in a specific tenancy.
- A refurbishment is typically about upgrading or refreshing an existing space, for example, updating an older office or retail tenancy without completely changing how it is used. It often focuses on finishes, service upgrades and amenity improvements.
- A renovation is a broader term and can refer to more structural or building-wide changes, such as repositioning a whole commercial asset, upgrading facades or reworking lobbies and common areas.
In practice, many projects combine elements of all three. For example, a building repositioning might involve renovating lobbies and amenities, refurbishing common areas and delivering new tenancy fitouts for incoming tenants.
The important point is to be clear on scope and intent so that design, approvals, budget and programme can be set up correctly from the start.
The commercial fitout process
Although every commercial fitout is unique, most follow a similar high level path from idea to handover.
Planning and brief
The process begins with planning and developing the brief. The tenant and project team clarify how the business works, how many people need to be accommodated, how customers will use the space and what constraints apply in the building.
At the same time, base-building information, landlord criteria, and live environment limitations are gathered so that the brief is grounded in reality rather than assumptions.
Design and documentation
Design and documentation turn that brief into drawings and specifications. Designers develop concept layouts and test fits, then refine them into detailed plans. Services engineers map how mechanical, electrical, hydraulic and fire systems will support the new layout.
Finishes, joinery and fixtures are selected, while compliance with the National Construction Code (NCC), accessibility standards and centre or building requirements is checked and built into the design rather than left as a late audit.
Budgeting and approvals
With a defined design, the fitout contractor prepares a detailed cost plan and programme. This is also when approvals are secured.
Depending on the building and location, these might include landlord design approval, building approvals and construction certificates, fire and essential services sign off and, in shopping centres, centre management approval. Addressing these early reduces the risk of redesign and delays.
Construction and delivery
Construction then delivers the physical work. The sequence typically runs from demolition and strip out, through services rough in and modifications, to new walls, ceilings and bulkheads, followed by finishes, joinery and final services connections and testing.
In live buildings or centres, staging, hoardings, noise control and safe access routes are managed so that neighbours can keep operating while work progresses.
Handover and occupancy
The final stage is handover and occupancy. Services are tested and commissioned, defects are rectified and as-built documentation is provided.
Once practical completion and any required certifications are in place, the tenant can move in, install furniture and begin operating in the completed space.
What affects the cost of a commercial fitout?
There is no single price for a commercial fitout. Costs vary widely based on the building, location, scope and quality level.
Key cost drivers include:
- Building size and layout: Larger areas and complex layouts naturally require more work
- Scope of works: The extent of demolition, new construction and services changes
- Existing condition: Whether services and structure are in good shape or need upgrades
- Services requirements: Intensive uses such as hospitality or healthcare often require more mechanical, electrical and plumbing work
- Finishes and joinery: Custom joinery, higher end finishes and feature elements increase cost
- Programme and staging: Tight timeframes, night works and complex staging in live environments generally add cost
- Compliance and approvals: Addressing NCC, accessibility and fire requirements may require additional works
Public guides that list ‘average fitout costs per square metre’ can be useful for very rough orientation, but they rarely capture building-specific constraints. A short conversation with a commercial fitout contractor will usually give a more realistic range for your situation.
Why choose an experienced commercial fitout contractor?
A commercial fitout touches almost every aspect of a tenancy and the building around it. The right contractor does more than just build walls and install finishes.
Aligning the brief with building reality
From the outset, a specialist commercial team can test the brief against the realities of the building. They can highlight services or structural constraints early and suggest simpler ways to achieve the same functional outcome.
This reduces the likelihood of redesign, cost shocks and programme blowouts later in the project.
Coordinating trades, services and live environments
During delivery, an experienced fitout contractor coordinates trades and services in the right sequence and manages interfaces with base-building systems.
They also know how to keep work zones safe and controlled in live centres or office towers, working with centre management, building managers and certifiers so approvals and inspections are built into the programme instead of interrupting it.
Providing clear accountability
Equally important is having one clear line of responsibility. When a single commercial-focused contractor manages the fitout and, where possible, related base-building works, there is a single point of accountability for cost, time, safety, and quality.
Problems are resolved within one team rather than bouncing between multiple parties, which is particularly valuable in disruption-sensitive environments.
BSG delivers fitouts as complete commercial construction projects, not just interior installations. That means integrating tenancy works with base building considerations, keeping a compliance first lens on design and delivery, and maintaining director level oversight on business critical projects as part of our broader tenancy works offering.
Conclusion and next steps
A commercial fitout is far more than choosing finishes and moving furniture. It is a coordinated construction project that has to balance business needs, building constraints, compliance requirements, and live-environment realities.
The most successful fitouts:
- Start with a clear brief and realistic budget
- Integrate NCC and landlord requirements into design, not as an afterthought
- Sequence demolition, services and finishes around live operations
- Rely on experienced, commercial-only project management
If you are planning a new tenancy, an office move, a retail refurbishment or a broader commercial fitout project, it is worth getting advice before you commit to drawings or leases.

FAQs
What is a commercial fitout?
A commercial fitout is the process of taking a base-building space, often an empty shell, and constructing the internal layouts, services and finishes needed so a specific business can use it. It covers everything from walls and ceilings to services, joinery and finishes.
What does a fitout include?
A typical fitout can include demolition and strip out, new partitions, flooring, ceilings, lighting, electrical and data, HVAC modifications, plumbing, joinery, finishes and, in some cases, coordination of loose furniture. The exact mix depends on the tenancy and agreed scope.
What is the difference between a fitout and a renovation?
A fitout usually refers to readying a tenancy for a specific occupant, while a renovation is a broader term that can cover building-wide or structural changes. Refurbishments often sit in between, focusing on upgrading or refreshing existing spaces without completely changing how they are used.
How long does a commercial fitout take?
Timeframes depend on size, complexity, approvals and whether the building stays live during works. Smaller, straightforward tenancies can be completed in a relatively short period, while larger or more complex fitouts in live environments take longer. The most accurate timing comes from a project-specific programme.
How much does a commercial fitout cost?
Costs vary with building size, scope, existing condition, services requirements, finishes and staging constraints. Public ‘per square metre’ figures are only a rough guide. A commercial fitout contractor can provide a realistic range once they understand your building and brief.
Do I need approvals for a fitout?
Most commercial fitouts require at least landlord and building approvals, and often fire and essential services sign off. In some cases, planning or change-of-use approvals are also required. Approval requirements depend on location, building classification and the nature of the works. For more on compliance and approvals, see our commercial building works overview.
Can BSG manage the entire fitout?
Yes. BSG manages the full fitout process – from planning and design coordination through to construction, commissioning and handover – as part of its end-to-end tenancy works and commercial building services.
