Renovating behind a retained frontage.
We first confirm the building's heritage contribution, then decide how an addition should meet it. Better living spaces can sit comfortably with the original rooms and materials that stay.

Builders in Mosman
SHORE Design + Build brings architecture, interiors and construction to Mosman homes, whether you want a new residence or a substantial alteration. We design around the outlook while protecting the parts of the property that matter.

01 / The proposition
Homes shaped by the harbour and the street
As builders in Mosman, we care how a home feels from inside as much as how it sits above the water or along an established street. The room where you spend the afternoon may need shelter, privacy or a link to the garden as much as an open view. Our architects and builders make those choices together.
Your zoning sets the starting point. Mosman's C4 Environmental Living land sits differently under the State housing reforms from eligible R2 and R3 land near Spit Junction and Cremorne. We confirm which rules reach your property before we plan a larger house, an addition or two homes.

Light through the centre of WHISPER
WHISPER is a six bedroom waterfront home in Mosman, with completion planned for 2027. We designed its architecture and interiors around a spiral stair beneath a stained glass skylight. Tall glazing opens the living spaces to the water outside. It gives us a local reference when we talk about light and circulation in your home, though its design and scale belong to that property.

WHISPER
Perched on the serene waterfront of Mosman, this luxury dwelling epitomises elegance and sophistication. At the heart of the home is a stunning spiral staircase that winds through the house.

Mosman zoning, heritage and approvals
Council's August 2026 DCP amendments added controls for dual occupancies and apartment development. We read the current documents alongside any State policy that applies to your land and the type of building you want.
- 01
Housing reforms depend on the zone.
Council identifies eligible R2 and R3 land within an 800 metre walk of the nominated Spit Junction and Cremorne centres. C4 Environmental Living land is outside this policy, so being near a centre does not settle eligibility on its own.
- 02
Conservation areas have their own guidance.
Around Bradleys Head Road, the DCP favours rear additions and keeping face brickwork, stone and garden character. We let the building's ranking guide the design before any facade changes are planned.
- 03
Approval is a separate test.
A complying development certificate needs the proposal and the land to satisfy every relevant criterion. Where that route is unavailable, a permissible scheme needs a development application. A housing reform map is never a substitute for approval.
- 04
Views beyond your boundary count.
Mosman's view sharing provisions consider public outlooks and neighbouring properties. We show the roof and upper rooms in context so their effect can be assessed while the design can still change.
How we plan a Mosman home
From the rooms you love to the first day on site
Tell us which rooms you enjoy in the house now and which ones no longer work. We use that brief to weigh an alteration against a new home before detailed choices become expensive to change.
Start with how you live.
We map where you want to cook, gather and spend time outdoors, then test those rooms against the outlook and the neighbouring windows. The goal is a better home, not simply more floor area.
Draw the house in section.
We set the proposed levels against the surveyed ground. For a basement or lower garden room, we identify the investigations needed to understand the excavation and how adjoining structures will be supported.
Resolve the exposed details.
We work through where glazing, roof and terrace meet with the consultants and suppliers. Harbour exposure and maintenance guide our choice of external finishes and fittings.
Carry it into the build.
We agree the drawings, retained elements and site arrangements the price covers. Our design and construction team then stays in the details right through the build.
The right scale of work for your property
Mosman renovations, rebuilds and new homes
A period house and a waterfront replacement call for different design thinking. We can start from a blank brief or join a project whose architect has already prepared drawings.
A knockdown rebuild.
We weigh how useful the current house is against the home you want to create. Demolition and replacement need their own planning assessment, including any heritage or scenic constraints.
Duplex or dual occupancy.
We check the property's zone and the housing policy that applies before treating two dwellings as an option. The layout follows once the permitted use and approval route are clear.
Building with your architect.
Share the design set and the decisions still open. We work through the building scope with your team, including how specialist finishes and difficult access affect delivery.

Heritage streets and harbour sites
Your street shapes the design too
Mosman Council identifies thirteen heritage conservation areas, including Bradleys Head Road and The Crescent. Its ranking maps show how each building contributes to its surroundings. That contribution matters even when a house is not a separately listed item.
A harbour outlook adds its own questions about how the building looks and how it meets the land. We work through both on your property itself. WHISPER is an example of our waterfront design work, not a plan we repeat elsewhere.
Questions to bring early
Building in Mosman: common questions
Does a C4 property in Mosman qualify for the housing reforms near Spit Junction?
No. Council's guidance excludes C4 Environmental Living land from the Low and Mid Rise Housing Policy. A nearby town centre does not change that. Your planner can confirm the actual zone and the policies that apply to the work you have in mind.
Can I change the frontage of a house in a Mosman conservation area?
Start with the building's contribution ranking and the area's guidance, even if the house has no individual heritage listing. Bradleys Head Road and The Crescent are separate conservation settings. We work out what the changes would remove or conceal before settling the facade.
Do I need a geotechnical report for a basement near a Mosman cliff?
Yes. Council's DCP requires one where excavation is proposed at or near a cliff face. Ground investigation and structural advice then show what the excavation involves. Temporary support and the route for removing spoil then go into the cost discussion.
Is WHISPER finished?
Not yet. WHISPER is scheduled for completion in 2027. Our Mosman design has six bedrooms and a spiral staircase lit by stained glass above, with living spaces looking towards the harbour. Its project page shows our architecture and interiors.
