How Long Does an Office Fitout Take in Sydney?

Last updated: 14 October 2026

How long does an office fitout take in sydney? For most tenancies the construction stage runs 6 to 16 weeks, and the full project from brief to move-in runs about 12 to 28 weeks once design, approvals and furniture lead times are included. A 100 square metre refresh can be finished in 4 to 6 weeks on site, while a 1,000 square metre premium floor commonly needs 14 to 20 weeks of construction alone. These are Office Fitouts Sydney working ranges, not guarantees, and the real date is set by the critical path, not by the number of trades on site.

This guide pairs with our articles on where the money goes and budget by business size. Here we focus on the program: what happens in which order, and what slips.

How long does an office fitout take in Sydney by size and specification?

Floor area matters less than people expect, because trades work in parallel. Specification matters more, because bespoke items take longer to make. The table shows our working ranges for construction on site, after approvals and materials are secured.

If you are working out how long does an office fitout take in Sydney for a lease negotiation, use the total of both columns plus procurement float, not construction alone.

What are the stages when you ask how long does an office fitout take in Sydney?

Every project passes through the same six stages. The durations below are typical for a standard 300 to 500 square metre tenancy.

1. Brief and site inspection (1 to 2 weeks). Headcount, hybrid attendance, meeting room mix, budget and the base building. Our free site inspection happens within 48 hours of your enquiry.
2. Concept, test fit and pricing (2 to 4 weeks). A tested layout, then a detailed fixed-price quote, which we deliver in 3 business days once the scope is agreed. Our test fit guide explains how this stage de-risks the rest.
3. Detailed design and documentation (2 to 4 weeks). Drawings, services layouts, joinery details and finishes selections.
4. Approvals (1 to 6 weeks, overlapping). Landlord consent, building manager induction and any certifier or council pathway.
5. Procurement and construction (8 to 14 weeks). Long-lead orders are placed early, then demolition, services rough-in, partitions, ceilings, finishes and commissioning.
6. Handover, defects and move-in (1 to 2 weeks). Practical completion, cleaning, cabling tests, furniture installation and the defects liability period.

Added up end to end, how long does an office fitout take in Sydney comes out between 14 and 28 weeks for the typical tenant, and the biggest variable is not building speed but how fast decisions are made.

Which approvals change an office fitout timeline in Sydney?

Approvals are the most common reason a program slips before a single wall is built. Three layers apply.

• Landlord approval. Most leases require written consent to the design and the contractor. Allow 2 to 4 weeks, longer in strata or heritage buildings. See our landlord approval guide.
• Building rules. After-hours work, loading dock bookings, lift protection and contractor inductions can extend a program by one to three weeks if they are not planned.
• Statutory approval. Many internal fitouts qualify for a Complying Development Certificate or exempt pathway, while larger changes need a development application. Check the NSW Planning portal early, and read our council approval guide.

Fire safety is the part that surprises tenants. Changes to partitions, sprinklers or egress can require certification before and after works, which is why we line up the certifier during design. Under the National Construction Code 2022 Amendment 2, current in NSW, alteration provisions apply to the parts of the building you change.

What is the critical path in an office fitout?

The critical path is the longest chain of dependent tasks. Everything else has float. In most Sydney fitouts the chain looks like this: approval, then services rough-in, then ceiling and partitions, then joinery and glazing, then final services, then commissioning and certification.

Four items repeatedly drive it:

• Air conditioning and fire services. Relocating diffusers, VAV boxes and sprinkler heads needs building-manager coordination and often after-hours shutdowns.
• Glazed partitions and doors. Custom glass and framing typically takes 6 to 10 weeks from order. Our glass partitions guide explains the safety grade and manifestation requirements.
• Joinery. Reception desks, kitchens and feature walls are made off site, commonly 4 to 8 weeks after shop drawing approval.
• Furniture. Stock 2 to 6 weeks, custom 8 to 14 weeks, imported 16 to 24 weeks. See furniture procurement timing.

Anyone asking how long does an office fitout take in Sydney should ask which of these four items is on their own critical path. Good programs order these items the day design is approved, not the day construction starts.

How long does an office fitout take in Sydney for a refresh versus a full fitout?

The short answer to how long does an office fitout take in Sydney for a refresh is a few weeks. A refresh keeps the walls and services in place and changes the surface layer: flooring, paint, lighting, a new kitchen or reception. Because services are untouched, approvals are usually light and a 200 square metre office can be finished in 3 to 6 weeks on site, sometimes in stages after hours.

A full fitout strips back to the base building. Demolition, services, framing, ceilings, glazing, joinery and finishes occur in strict sequence, and each trade needs the one before it to finish. That is why a 500 square metre full fitout takes 10 to 14 weeks even with a large crew.

Sample program: how long does an office fitout take in Sydney for 25 people?

A worked example makes the answer concrete. Take a 275 square metre standard fitout for a 25-person professional services firm in a Sydney CBD building with a cooperative building manager.

That is about 22 weeks end to end, with 10 weeks on site. Ask any provider quoting a much shorter total how they plan to handle approvals and glass lead times. Compressing the front end is possible, but only if you decide faster, not if the builder works faster.

How long does an office fitout take in Sydney while staff stay in the building?

Working around an occupied floor adds time because noisy and dusty tasks move to evenings and weekends, and the floor is delivered in zones. Plan on roughly 15 to 30 per cent more on-site duration, and ask for a staging plan that shows where people sit each week. Our guide to keeping your team working during a fitout explains dust, noise and access controls in detail.

Sector differences: how long does an office fitout take in Sydney for law, tech or medical tenants?

• Legal and finance. Acoustic privacy, secure rooms and heavier joinery push construction toward the top of the premium range, often 14 to 18 weeks for 600 square metres.
• Technology and creative. Open plan with lighter finishes is quicker, but cabling, AV and comms rooms need early coordination.
• Medical and allied health. Hydraulics, infection control and additional approvals can add 4 to 8 weeks.
• Government and high security. Accreditation and access controls add design and inspection steps before handover.

Can you speed up an office fitout without cutting quality?

Yes, but through decisions, not overtime. These levers shorten a program reliably:

• Appoint a design-and-construct provider early so design, pricing and procurement overlap. Compare routes in our sequencing guide.
• Freeze the brief before documentation. Late changes to meeting room counts or power layouts are the biggest single cause of delay.
• Pre-order long-lead items at design sign-off.
• Book building access early: lifts, loading dock, shutdowns and inductions.
• Stage the work in zones so part of the team can move earlier, which is possible in occupied buildings.
• Use standard products where bespoke adds weeks but little value.

So how long does an office fitout take in Sydney depends mostly on how early you commit. Overtime and weekend shifts can recover one to two weeks but raise cost and rarely fix a late order.

How to plan backwards from your move date

Because the answer to how long does an office fitout take in Sydney is a range, work backwards from the date that matters, usually a lease expiry, make good deadline or an end-of-financial-year move.

1. Start from the target move-in date and subtract 1 to 2 weeks for furniture, cabling tests and cleaning.
2. Subtract the construction duration from the table above.
3. Subtract the longest lead-time item and its approval, whichever is greater.
4. Subtract design and approvals.
5. Subtract the brief and pricing stage.
6. Add 10 to 15 per cent float for weather, supply and inspections.

For a standard fitout, most Sydney tenants should begin engaging a fitout provider five to seven months before the date they need to occupy. If your lease ends sooner, tell us in the first call and we will show what can be compressed. Our best office fitouts Sydney page explains how we run these programs.

Common reasons an office fitout runs late

• Brief changes after design sign-off, such as new meeting rooms or a larger kitchen.
• Landlord or certifier comments that arrive late and require redesign.
• Hidden conditions after demolition: asbestos, unsealed penetrations, undocumented services.
• Long-lead items ordered after construction starts.
• Access limits in the building, such as lift availability and noise restrictions.
• Unclear scope between the head contractor and the tenant’s IT or furniture suppliers.

Each of these changes how long does an office fitout take in Sydney for your project. Older buildings carry the highest risk. Our work on older-building compliance shows why a pre-demolition hazardous materials check belongs in week one, as required under WHS duties described by Safe Work Australia and SafeWork NSW.

Frequently Asked Questions

How long does an office fitout take in Sydney for a small office?

A 100 to 200 square metre office typically needs 4 to 8 weeks on site and 10 to 16 weeks in total once design and approvals are included.

How long does an office fitout take in Sydney for a large floor?

A 1,000 square metre or larger floor commonly needs 14 to 20 weeks of construction and 24 to 32 weeks from brief to handover.

What delays furniture delivery?

Custom and imported items. Stock furniture arrives in 2 to 6 weeks, imported ranges can take 16 to 24 weeks, so order at design sign-off.

How early should I engage a fitout company?

Five to seven months before occupancy for a standard fitout, and earlier for specialised projects or buildings with strict landlord processes.
