Case Study: Fixing the Common Areas at a Holker Street Business Park, Newington
In early 2026 the building manager of a four-building business park on the Holker Street corridor in Newington NSW 2127 came to us with a problem that had nothing to do with any individual cleaner. Eleven tenancies, two basement parking levels, a shared end-of-trip facility, and a cleaning arrangement so fragmented that the lobby carpet had become a philosophical question. The estate is anonymised at the owner's request; the scope, numbers and outcomes below are as delivered.
Diagnosis: a boundary problem, not a cleaning problem
The audit took half a day and found almost nothing wrong with the actual work being performed. What was wrong was who owned what:
- Common areas were cleaned under an outgoings-funded contract; each tenancy held its own separate arrangement, and four had no contract at all
- The shared kitchen and end-of-trip facility appeared in nobody's written scope — both parties assumed the other had it
- Basement ramps and car park levels were swept quarterly, which on a corridor with this much heavy vehicle movement meant grit was permanently walking into every lobby
- The bin compound was hosed on request rather than on a schedule, and requests only happened after a complaint
- No reporting existed at all, so the building manager was the complaints system
The rebuild
- One named supervisor took the whole estate, with a written scope that explicitly marked the line between common property and tenancy scope — including the shared kitchen and end-of-trip facility, which went into common
- Five of the eleven tenancies moved their internal cleaning onto the same agreement at portfolio pricing, leaving one point of contact for most of the building
- Grit was attacked at the boundary: weekly ramp and car park sweeping, entry matting rotated and washed, and quarterly machine work on lobby hard floors instead of endless mopping
- The bin compound went onto a fixed weekly washdown and deodorising cycle, with dumped items photographed and logged
- A monthly photo audit against the written scope, plus a defect log for failed lighting, damaged pavers and blocked drainage, issued to the building manager
The result
Logged tenant complaints about common areas fell from roughly four a month to a single complaint across the following quarter. The two tenancies that had raised cleaning at lease renewal both signed. The common area line in outgoings rose about eight percent — honestly, because the previous scope was under-serviced — while the five consolidating tenancies each paid less than they had under their own contracts. The building manager's own words were that they had stopped being the cleaning department. The agreement runs month-to-month, like every contract we write.
Questions about this case study
What kind of site was this?
A four-building multi-tenant business park on the Holker Street corridor in Newington 2127, roughly 6,400 square metres of lettable area across eleven tenancies, with two shared basement parking levels and a common end-of-trip facility.
What was going wrong?
Common areas were funded through outgoings and cleaned under a separate contract to the tenancies, so anything at the boundary — lobby carpet, shared kitchen, bin compound, car park ramps — was nobody's job. Tenant complaints were running at roughly one a week and two tenancies had raised it at lease renewal.
What changed?
One named supervisor took the whole estate. The written scope explicitly marked where common property ended and tenancy scope began, five of the eleven tenancies moved their internal cleaning onto the same agreement, and a monthly photo audit went to the building manager against that scope.
Was it more expensive?
The common area line rose about eight percent because the previous scope was genuinely under-serviced. Total spend across the estate fell for the five tenancies that consolidated, since portfolio pricing beat their individual contracts.
What were the results?
Logged tenant complaints about common areas dropped from around four a month to one in the following quarter. Both tenancies that had raised cleaning at renewal signed. The building manager stopped fielding cleaning calls entirely and now forwards the monthly audit into their own owner reporting.
