A home renovation in Mosman costs $100,000–$500,000+. Kitchen from $30K, bathroom from $20K, full renovation from $150K. Buildana manages design, Mosman Council approvals (where required), and construction under one fixed-price contract.
Mosman Renovation Specialists
Restoration is the only renovation standard Mosman accepts. The 1880s to 1940s houses on these 500 to 1,000m² blocks, Federation mansions off Military Road and inter-war homes stepping down to Mosman Bay and Sirius Cove, sit almost entirely within Heritage Conservation Areas. The work that holds value here is restoration-grade. Slate matched to slate, joinery reproduced from profile, sandstone repointed by hands that have done it before. At $4.5M to $8.0M, the market can tell the difference from the footpath.
The harbour fall is the second discipline. Substantial slope on the bay-side streets means renovations regularly involve structural steel, underpinning and drainage design the original builders never attempted, all engineered around sandstone that appears exactly where it is least convenient. Approvals demand patience and precise documentation, and we carry both. For a house of this calibre, the renovation should add a generation of life, not a coat of paint.
What I would check first on a Mosman home: the heritage listing and the fabric worth conserving, the harbour fall and rock, and where a rear reconfiguration can open the house. Those set the scope.
We restore these homes fixed-price, licence HBL 487805C. Speak with us about doing it once, properly.

The market reads the difference from the footpath
On a $4.5M to $8.0M Mosman house, a cheap renovation is obvious from the street and the market discounts it accordingly. So the work that holds value is restoration-grade: slate matched to slate, joinery reproduced from profile, sandstone repointed by people who have done it before.
That is not gilding. It is the standard the suburb and the Conservation Areas expect, and it is what keeps a Mosman home worth what it costs.
Harbour-fall engineering
The bay-side streets fall substantially, so renovations regularly involve structural steel, underpinning and drainage design the original builders never attempted, all around sandstone that appears where it is least convenient. That is engineering, and it has to be scoped honestly.
Approvals demand patience and precise documentation, and we bring both. Send us the address and we will read the heritage, the fall and the fabric together, and tell you what doing it properly takes.

How It Works
From First Call to Final Key
Free consultation at your Mosman home. We inspect the property, discuss what you want to change, check for asbestos in 1880s–1940s heritage-era construction, and provide a realistic budget range and timeline.
⏱Renovation design isn't just "new finishes on old layout" — the best returns come from rethinking how rooms connect. Removing a wall to open kitchen-dining-living, or repositioning a bathroom to free up bedroom space, often delivers more impact than any finish upgrade.
⏱Cosmetic renovations don't need approval. Structural changes require DA or CDC through Mosman Council. Buildana assesses and manages the approval pathway.
⏱Construction covers strip-out, structural modifications (if any), waterproofing, rough-in services, fit-out, tiling, cabinetry, painting, and final clean. Staged to minimise disruption to your daily routine.
⏱Documentation pack at handover: warranty for new work, waterproofing certificates for wet areas, electrical compliance certificate, plumbing compliance, BASIX update if envelope changed, OC if structural. Keep with the property file for future sale.
⏱Quality Promise
Mosman renovation specialists: we plan around liveability. Staged works, weatherproofing, realistic timelines — not optimistic ones.
