Types of Commercial Fitouts We Deliver

ATH Projects delivers commercial fitouts in Sydney and regional NSW across four main sectors, each with its own priorities around layout, services and brand. Below is how we approach each one, with completed work you can explore in our commercial fitout portfolio.

An office fitout turns an empty floorplate into a working layout. That means workstations, glass-walled meeting rooms, breakout kitchens and a reception that sets the tone for visitors. We plan each zone around how your team works day to day. Our Transport Mutual Credit Union project paired open-plan desks with timber shelving and a café-style breakout, while Money Quest centred on a welcoming client reception.

Retail & Shop Fitouts

A retail fitout has to sell the brand before a customer reaches the counter. We deliver service counters, display and storage joinery, lighting, signage-ready walls and hard-wearing finishes built for constant foot traffic. Our Storage King fitout carried the brand's colours through a customer-facing site designed for daily trade. Where a store is already operating, we stage works or schedule them outside trading hours so it can keep serving customers.

Warehouse & Industrial Fitouts

Warehouse fitouts focus on the spaces people use every day inside an industrial shell: site offices, amenities, lunchrooms and kitchenettes. We coordinate partitions, ceilings, electrical and plumbing so these areas are compliant and comfortable without interrupting operations on the warehouse floor. Our Tuggerah Warehouse project included a fully fitted kitchenette within the industrial space, built to handle heavy daily use by staff.

Banking & Branch Fitouts

Bank and credit union branches need to feel open and approachable while protecting customer privacy and security. We fit out enquiry points, private interview rooms, staff areas and branded feature walls, working to the brand guidelines financial institutions typically provide. Our branch projects include IMB, CFB Narellan and CFB Edgeworth, where feature walls and financial services signage bring the brand into the customer space.

Shell & Core, Category A and Category B Fitouts Explained

These three terms describe how much of a commercial space the landlord finishes and how much the tenant fits out. Knowing where your tenancy sits tells you what you're paying for before the build starts.


Shell and core is the base building. The landlord provides the structure, façade, lifts, stairs, common areas and core services such as the main switchboard, risers and fire services backbone. Inside the tenancy, you'll usually find a bare concrete floor and an exposed ceiling.


A Category A fitout makes the space usable but empty. The landlord typically adds suspended ceilings, base lighting, air-conditioning distribution, sprinklers and smoke detection, and finished floors.


A Category B fitout is the tenant's work, covering partitions, meeting rooms, kitchens, joinery, data cabling, branding and furniture. It often also involves adjusting the Category A lighting, air-conditioning and sprinklers to suit the new layout.


Exact definitions vary between leases, so we review your lease and the landlord's fitout guide early. Your lease will also set out your make good obligations, which usually require you to return the space to its original or Category A condition when you leave. It's worth understanding these obligations before you sign.

Our Commercial Fitout Process

Our design and construct process keeps design, approvals and construction under one team, so there's one point of accountability from the first site visit to handover. Here's what each stage involves. You can also see an overview of our process.

1. Site Assessment & Brief

We start on site, measuring the tenancy and checking existing services, ceiling heights and base building conditions. We also review the landlord's fitout guide. Alongside this, we document your brief: headcount, operational needs, brand requirements, budget and timing.

2. Design & Documentation

Our interior design team develops the layout, finishes and joinery details. These are then turned into construction documentation for each trade scope: partitions, ceilings, joinery, electrical, plumbing and data. Locking these down before construction keeps pricing accurate and prevents variations on site.

3. Approvals

We prepare and lodge what your project needs, whether that's a Complying Development Certificate (CDC) or a Development Application (DA). We also coordinate building manager approvals and landlord sign-off. Approvals run alongside documentation so they don't hold up the start date.

4. Construction

Our project management team schedules and supervises every trade on site. In occupied buildings and live environments, we stage the works or complete noisy tasks after hours to suit building rules and your operations.

5. Handover & Defects Support

At handover you receive certification, warranties, operation manuals and as-built information for your space. We stay on for the defects liability period and attend to any items that come up once your team has moved in.

Approvals & Compliance for Sydney Fitouts

Most commercial fitouts in Sydney need some form of approval before work begins. The right pathway depends on the scope of work, the building's classification and its location. Here are the main requirements we manage on NSW projects.


CDC or DA. Some minor internal works may qualify as exempt development. Most fitouts, however, go through either a Complying Development Certificate or a Development Application. A CDC is a fast-track approval issued by a registered certifier or council when the work meets set standards under the NSW State Environmental Planning Policy (Exempt and Complying Development Codes). Works that fall outside those standards, such as some heritage-listed buildings or certain changes of use, need council approval through a DA.


NCC building classifications. The National Construction Code (NCC) includes the Building Code of Australia and groups buildings by use. Offices are Class 5, shops are Class 6 and warehouses are Class 7b. The classification sets the requirements for fire resistance, exits, facilities and access, so confirming it early shapes the whole design.


Fire safety. New walls and ceilings can affect fire services such as sprinkler coverage, smoke detection, exit signs and emergency lighting, as well as paths of travel. Where fire safety measures are added or altered, NSW requires them to be certified on completion. They're then included in the building's annual fire safety statement.


Accessibility. New and upgraded work must meet the Disability (Access to Premises — Buildings) Standards 2010 and the NCC's access provisions. This covers items such as circulation space, door widths, accessible amenities and counter heights.


Landlord, building manager and strata sign-off. Even with council or certifier approval, most leases require landlord consent for your fitout drawings. Building managers set rules for work hours, lift bookings, hot works and fire system isolations. In strata-titled commercial buildings, the owners corporation's by-laws may also apply.

Every site is different, so your certifier confirms the final approval pathway for your project. We coordinate the documentation so nothing stalls once construction is ready to start.
