Office Defits Perth

Strip Outs, Make Goods and Office Expansions

Office defits and expansions, managed in-house from strip out to handover

Registered builder BP12706

CM3 pre-qualified

12-month craftsmanship warranty

If you’re a Perth commercial tenant with a lease ending, a landlord taking a space back, or a business that has outgrown its floor, here are the two jobs that follow: the defit that returns a tenancy to the condition the lease describes, and the expansion that turns the floor next door into part of the business.

Both decide whether your bank guarantee comes back and how long the business is disrupted, and both are planned around a lease date.

Office Fitout Professionals (OFP) is a Balcatta-based, CM3 pre-qualified registered builder (BP12706) with one of the largest partitioning teams in the business and the demolition, electrical, plumbing, air conditioning, painting and flooring trades in-house. We cover all tenancies and defits, from an office on St Georges Terrace to a warehouse in Bibra Lake.

Project example
At 182 St Georges Terrace, we demolished the old fitout to a warm shell, then completed a full fitout, renovated the amenities and upgraded the lift lobby.

What is Design and Construct

Defits

Office defits: returning a tenancy to base building condition

A defit, sometimes called a strip out or a make good, returns a tenancy to the base building condition or to the condition set out in your lease. Tenants need one at lease expiry or when relocating, and landlords when they want a presentable base fitout to take a space back to market. If you’re moving, we can fitout your new space while the old one is stripped out, with one team on both.

Before work starts

The scope starts with the lease, not the floor: we walk the tenancy against your lease obligations, confirm what the landlord wants kept, and agree scope, budget and handback date before anything comes out. A defit usually covers:

Partition and joinery removal

Taking out the plasterboard and glass partitions, built-in joinery, reception counters and screens you installed, and making good the ceilings, walls and floors behind them. Our partitions team builds these systems, so it knows which fixings hold a glazed suite together and which hold the ceiling up.

Demolition and strip outs

Demolition and make-safe works, sequenced from the ceiling tiles and grid down to the partitions, joinery and floor coverings, without touching the building’s structure, waste removal included. The order matters: ceiling first, so nothing hangs over a wall about to go, floor last, so trades are not working on bare slab.

Services

Making safe and removing electrical, data, lighting and air conditioning additions, with services isolated before any strip out begins and the fire detection and sprinkler systems kept compliant as walls come down. Lift bookings, after-hours windows for noisy work, waste removal and hot work permits can all slow a defit, so we raise them with the building manager early, and CM3 pre-qualification gives us fast and easy access to many buildings in Perth.

Walls, ceilings and floors

Patching and painting walls, repairing or replacing ceilings, and cleaning, repairing or replacing carpet and vinyl, so the tenancy goes back in the condition you received it. It is what the landlord’s inspection looks at hardest, and passing it usually releases the bank guarantee.

Shop defit and industrial strip outs

Warehouses add bolts and fixings to remove from slabs, epoxy repair and painting. A retail or shop defit adds shopfront, counter and display removal, to the landlord’s base building condition.

Expansions

Office Expansion Perth: growing without moving

When the business needs more space, an office expansion can extend into an adjoining tenancy, sub-divide or rezone the floor you have, or add rooms through new office construction, demolition and sub-division.

Planning an expansion

Building permits and the National Construction Code apply, the base building condition shapes the cost, and mechanical and electrical services are a major part of the budget, so we plan on the floor plate first. Open-plan desk areas with quiet focus zones, acoustic separation and ergonomic workstations rather than more rows of cubicles make the new area one working environment with the old, and where the business keeps operating, the works are staged.

Why OFP

Frequently Asked Questions

Office Fitout Professionals (OFP) in Balcatta carries out the office defits Perth tenants need at lease expiry, along with strip outs and make goods, as a CM3 pre-qualified registered builder (BP12706), with partitioning, demolition and trades in-house. 

A defit is the physical strip out of the fitout you installed. A make good is the lease obligation to return the tenancy to an agreed condition, usually the defit plus repairs, painting and floor coverings. Our make good service covers both. 

Several months before lease expiry. Trades, approvals and building access all take time, and the works must finish before you hand back. 

Yes, where the site allows. We build the new area first, behind a sealed temporary wall, while your team keeps working in the existing office. Noisy work is booked for after hours or weekends, and the wall between the old and new space is the last thing to come out, so you are never working beside an open building site.  

Scope is the biggest variable, from removing a few partitions to a full strip out or a new floor. We provide an itemised quote with a complete cost breakdown of building costs and individual trades.
