The hard part is getting everything in

Mosman’s building stock is unusually good and unusually hard to reach: interwar houses, walk-up flats and boutique blocks, on streets that fall steeply toward the harbour.
Access is the first question on almost every Mosman job and the one most often answered too late. Narrow streets, no on-site parking, stair-only entry to a great many apartments, and a lift, where there is one, that was never intended to carry a bath up eight floors.
That governs everything downstream. What size sheet of stone can physically reach the apartment. Whether the joinery is built off site and assembled in place. How long the street is occupied and what the council will permit. Getting these settled before pricing is what stops a Mosman renovation drifting.
Above that, the work itself is finish-led: kitchens and bathrooms in stone, brass and tile, in apartments where the neighbours are two metres away through a slab and the building has rules about when you can make noise.
What we do in Mosman
Apartment and whole-home work, on sites that make both harder than they look.
Apartment renovation
Kitchens, bathrooms and full reconfigurations in occupied blocks, sequenced around building rules and neighbours.
Stone, tile and joinery
Finish-led work set out properly, including the pieces built off site because they will not fit up the stairs.
Structural alterations
Removing walls in a strata building, where what you are cutting into may be holding up the apartment above.
Wet areas and balconies
Bathrooms and terraces re-membraned and reinstated properly. The most common source of a claim from the apartment below.
Access planning
Craneage, street occupation and stair logistics worked out before pricing, because in Mosman that is the price.
Strata approvals
Owners corporation consent and by-laws navigated before work starts, not discovered once the tiles are off.
Why Mosman jobs are priced differently
The building work in a Mosman apartment renovation is not unusual. The logistics around it are, and that is where the money goes.
Getting things in
A great many Mosman apartments are in walk-up blocks with no lift, or with a lift that cannot take long lengths. That decides the maximum size of everything: stone slabs, bath tubs, sheets of glass, lengths of timber. Joinery is frequently built off site in sections and assembled in the apartment, which is more expensive than a single fitted piece and the only thing that actually works.
Getting things out
Demolition waste has the same problem in reverse, and on a street with no parking and a steep grade there is often nowhere to put a skip without a permit. Waste handling on these jobs is a line item, not an afterthought.
The street
Occupying part of a narrow Mosman street needs council permission and a plan, and neighbours notice immediately. Sorting that in advance is the difference between a job that runs and one that is stopped in week two.
Working inside a strata building
Most apartment work here needs owners corporation approval, and often a by-law where common property or waterproofing is affected. That process takes time, frequently longer than the work itself, and starting it late is the most common reason a renovation sits waiting.
There are also almost always rules about working hours, lift protection, and how common areas are to be left each day. We would rather read the by-laws before quoting than discover them from a complaint.
Waterproofing is the risk that matters
In a strata building the failure that becomes expensive is not the one in your apartment, it is the one that appears on somebody else’s ceiling. Bathrooms and balconies get re-membraned properly and tested, because the alternative is a claim against the works years later. By then the argument is about who did what.
Houses on the slope
Mosman’s interwar houses sit on blocks that often fall steeply from the street to a harbour outlook at the rear. The good news is that the view is at the back, which is where the planning controls are loosest. The difficulty is retaining, excavation and getting plant to the low side of a site that a truck cannot reach.
The pattern is the same as the apartments: the structure is ordinary, the access is not, and the access is what should be resolved before anyone commits to a number.

Yes. A high-end apartment renovation with a rebuilt entertaining terrace, delivered design-and-construct. It is published as a case study on this site.
Almost certainly, and often a by-law as well if common property or waterproofing is affected. Structural changes and wet areas both usually trigger it.
It is worth starting that process early. The approval frequently takes longer than the building work, and it is the most common reason a renovation sits waiting.
In pieces, or not at all. Where a slab cannot physically reach the apartment we set the work out for jointed pieces in places where the joint is designed rather than apologised for, or build the element off site in sections and assemble it in place.
That is decided at set-out, which is why measuring the stairwell is part of quoting a Mosman kitchen.
Yes, and we plan the programme around them rather than treating them as an obstacle. Most Mosman buildings restrict noisy trades to set hours on weekdays.
It lengthens the programme, which is exactly why it should be in the programme from the start.
