Every office relocation involves a period where the business operates across two locations simultaneously. The old office is still occupied, or its defit is underway, while the new office is being built or awaiting certification. During this overlap, the business is paying rent on both premises, coordinating with two landlords, managing two sets of building access rules, and trying to keep its team productive despite the uncertainty of not being fully settled in either place. The stress of this period does not come from the construction itself. It comes from the coordination gaps between two parallel workstreams that each have their own timelines, their own stakeholders, and their own capacity to create surprises that ripple across to the other site.
The businesses that navigate this period well treat it as a defined project phase with its own plan, its own budget, and its own accountability structure, rather than as an unavoidable inconvenience between the old office and the new one.
Why the Overlap Period Is the Riskiest Part of a Relocation
The overlap period concentrates more risk per week than any other phase of the relocation. The new fitout may be nearing completion but not yet certified, which means the team cannot move in. The old office may have a hard lease-exit deadline that cannot be extended, which means the defit must begin on schedule regardless of whether the new office is ready. The business is exposed financially because it is paying rent on both spaces, and every day the overlap extends adds cost that was not in the original budget.
This time pressure creates a decision environment where urgency overrides careful planning. The defit starts before the new fitout is certified because the lease deadline is approaching. The team moves before the new office is fully commissioned because the old office is being stripped. IT systems are disconnected before the new systems are tested because the old landlord needs the space clear. Each of these decisions makes sense in isolation but creates downstream problems because the coordination between the two sites was not planned with enough specificity to absorb the pressure. Common relocation mistakes cluster in this overlap period because the margin for error is smallest when two parallel workstreams are competing for the same management attention and budget.
Two Landlords, Two Sets of Rules, One Timeline
The old office and the new office sit in different buildings managed by different landlords with different requirements. The old landlord’s concern is the make good: when will the space be restored, to what standard, and will the tenant meet the lease-exit deadline. The new landlord’s concern is the fitout: will the work comply with their building standards, when will the occupation certificate be issued, and when will the tenant begin paying rent on the new space. Each landlord has their own approval processes, their own building management rules for contractor access, lift bookings, after-hours work, and noise restrictions, and their own timeline expectations that may not align with each other or with the business’s operational needs.
Managing both sets of requirements simultaneously requires a single coordination point that has visibility across both sites. Without it, a delay in obtaining the new landlord’s fitout approval pushes the new office completion date, which extends the overlap period, which creates pressure on the old office make good timeline, which may trigger a breach of the old lease if the defit cannot be completed within the remaining time. The cascade is predictable and preventable, but only when both timelines are managed together rather than independently.
How Staff Experience Deteriorates During Poorly Managed Overlap
The team feels the overlap period more acutely than anyone else in the process. They are told the new office is coming but given vague dates. They are asked to pack their desks but not told when the move will happen. They arrive at the old office to find sections stripped out and utilities reduced. Their IT systems go through a transition that may involve temporary solutions, downtime, or unfamiliar configurations. The uncertainty is stressful, and stress reduces productivity at exactly the moment when the business needs the team performing because the relocation is already costing money.
Managing the staff experience during the overlap requires specific, honest communication about what is happening, when, and what the team should expect. A move date that is realistic rather than optimistic. A packing schedule that gives people enough time to prepare. An IT transition plan that minimises downtime and includes support for the adjustment period. Maintaining office functionality in the old space for as long as the team occupies it, rather than stripping services prematurely to get ahead of the defit schedule, keeps the team productive and confident during the transition rather than frustrated and disengaged.
Furniture, IT, and Storage Decisions That Cannot Wait
The overlap period forces decisions about physical assets that must be resolved before the move rather than during it. Which furniture transfers to the new office and which is disposed of or sold? What goes into temporary storage if the new office is not ready when the old office must be vacated? When does IT disconnect at the old site, and when does it reconnect at the new site, and is there a gap between the two that the business needs to plan around? Each of these decisions has cost and timing implications, and each becomes more expensive and more disruptive when it is made reactively rather than planned in advance.
Furniture that needs temporary storage because the overlap timing does not align adds a cost that the relocation budget may not have included. IT systems that are disconnected before the new systems are ready create a period where the business cannot operate at full capacity. Assets that are disposed of and then discovered to be needed at the new site require replacement at higher cost than retention would have been. These are not construction decisions. They are operational decisions that arise from the overlap and need to be resolved as part of the overlap management rather than left to the team to figure out under pressure.
Why a Single Coordinating Point Across Both Sites Matters
The overlap period involves multiple parties: the old landlord, the new landlord, the defit contractor, the fitout contractor, the IT provider, the furniture supplier, the removalist, and the business itself. Each party manages its own scope and its own timeline, and without a single coordinating point that has visibility across all scopes and both sites, the interfaces between parties become the source of delays, conflicts, and cost overruns.
The defit contractor finishes early but the removalist is not booked until the following week, so the old office sits empty while rent continues. The fitout contractor needs an extra day for commissioning but the removalist is already scheduled for the original date, so the team moves into an office that has not been fully tested. The IT provider disconnects at the old site on Thursday but the reconnection at the new site is scheduled for Monday, so the business loses a working day. Each of these misalignments is caused by the absence of coordination between parties that are each operating correctly within their own scope but not synchronised with the parties around them.
After-Hours Work as a Strategic Tool, Not a Panic Response
After-hours work during the overlap period is often used to accelerate timelines when the programme is under pressure. This can be effective when it is planned strategically: specific tasks that cannot be done during business hours because they create noise, require power shutdowns, or need access to areas that are occupied during the day. It becomes expensive and counterproductive when it is used reactively to recover time that was lost to poor coordination, because after-hours labour rates are higher, worker fatigue reduces quality, and the rushed pace increases the risk of defects that require rectification. Working with an experienced fitout team helps distinguish between after-hours work that genuinely helps and after-hours work that is masking a coordination failure that should be addressed rather than compensated for.
Planning the Overlap as a Project Phase
The overlap period is not a gap between two projects. It is a project phase in its own right, with its own scope, its own budget, its own timeline, and its own risk register. The scope includes the defit at the old site, the commissioning at the new site, the physical move of furniture, IT, and people, and the operational transition that keeps the business running through the change. The budget includes the dual rent, the storage costs, the after-hours work, and the contingency for the timing misalignments that the overlap will inevitably produce. The timeline integrates both sites into a single programme so that decisions at one site are made with awareness of their impact on the other.
Treating the overlap as a defined phase rather than an unfortunate byproduct of the relocation allows the business to manage it deliberately, budget for it accurately, and navigate it without the chaos that comes from treating two interdependent projects as though they are independent.
We deliver fitout and defit projects across Sydney where the overlap between old and new offices is managed as part of the programme. If you are coordinating two offices and want to keep the transition controlled, we can help.
