A granny flat in McMahons Point costs $150,000–$300,000+ depending on size and finishes. 1-bed from $150K, 2-bed from $200K. CDC fast-track approval in 10–15 business days. Buildana manages design, North Sydney Council approval and fixed-price construction.
McMahons Point Secondary Dwellings
Granny flat in McMahons Point is effectively impossible — Heritage Conservation Areas cover the entire residential core, tight 200–450m² blocks don't accommodate compliant setbacks, and harbour-fall engineering rules out siting. Realistic advice is to redirect investment to extension or restoration.
On the ground in McMahons Point (2060), the practical numbers shape every granny flat. Class M (sandstone) / H–E (harbour fall) soil — extremely reactive clay — pushes engineered foundation work into the $45,000–$80,000 bracket on most 200–450m² blocks. R3 Medium / R4 / B4 mixed zoning under North Sydney Council sets the building envelope, with R3 Medium Density pockets that open up dual occupancy options on qualifying lots. Median sale price across McMahons Point sits at $3.2M–$6.5M, which frames the build-versus-buy decision from the start. Nearest rail is North Sydney (1 km), McMahons Point ferry, and that proximity affects everything from rental demand to construction site access.
Buildana manages the full granny flat process in McMahons Point — from site assessment and CDC fast-track approval through to fixed-price construction and handover. We build studio, 1-bedroom, and 2-bedroom designs up to the NSW maximum of 60m².

Why Build a Granny Flat in McMahons Point?
McMahons Point is the harbourside peninsula north of the Harbour Bridge with Blues Point Tower at the tip. Federation cottages, sandstone terraces and apartments on tight 200–450m² blocks with significant harbour fall. Heritage Conservation Areas cover the entire residential core. Sandstone-dominant; engineered foundations standard. Premium for direct harbour and bridge views.
McMahons Point's established streetscape and median house prices of $3.2M–$6.5M reflect a premium location within North Sydney. Building costs sit above the metro average, offset by stronger capital growth and rental returns. Transport access via North Sydney (1 km), McMahons Point ferry connects McMahons Point to the wider Sydney network. Secondary dwellings on 200–450m² blocks deliver rental returns of $700–$950/week per week. CDC approval through a private certifier typically takes 10–15 business days. Soil conditions in McMahons Point (Class M (sandstone) / H–E (harbour fall), extremely reactive) are factored into every Buildana foundation design.
Granny flats in North Sydney deliver the lower north shore's strongest rental yields — $700–$1,000/week typical, $850–$1,100/week in harbourside Cremorne, Neutral Bay and Waverton driven by inner-suburban premium demand. Block sizes are tight (300–550m²) so site planning is the binding constraint, not the 60m² SEPP allowance. Heritage Conservation Areas across most harbourside suburbs restrict granny flat placement, materials and form — Kirribilli, Lavender Bay, McMahons Point, Milsons Point are effectively impossible without a heritage-grade DA. Sandstone foundations on ridge lots; suspended slabs and substantial retaining on harbour-fall lots add $30K–$80K. Tree Preservation Order LGA-wide. CDC available for SEPP-compliant designs outside heritage zones; otherwise full DA. Realistic build cost $230K–$380K for premium 60m².
Planning Controls — North Sydney Council
North Sydney LEP 2013 & North Sydney DCP 2013. R3 Medium Density dominates much of the LGA: FSR up to 0.85:1, building height 8.5–12m varying by precinct. R4 High Density along the North Sydney CBD edge and the Victoria Cross Metro 2024 SEPP precinct permits substantially higher FSR and height. B3/B4 mixed-use zones along Pacific Highway, Miller Street and Military Road. R2 pockets exist in Cammeray, Cremorne, Neutral Bay and parts of Waverton/Wollstonecraft with FSR 0.5:1 and minimum 9m frontage. Heritage Conservation Areas cover virtually all of Kirribilli, Lavender Bay, McMahons Point and Milsons Point, plus pockets of Cammeray, Neutral Bay, North Sydney, Waverton, Wollstonecraft and Cremorne. Tree Preservation Order applies LGA-wide. The 2024 Victoria Cross Metro SEPP TOD precinct opens density bonuses inside 400m of Victoria Cross Metro station — major redevelopment opportunity in central North Sydney. Crows Nest Metro 2024 SEPP also affects the Crows Nest portion of the LGA. Substantial harbour-fall sites on Kirribilli, Milsons Point, McMahons Point, Lavender Bay, Waverton, Cremorne Point and Kurraba Point require engineered slab and retaining design.

Building in McMahons Point — Local Context
McMahons Point Block Realities
Typical McMahons Point blocks are 200–450m² on Class M (sandstone) / H–E (harbour fall) ground (extremely reactive clay). For a secondary dwelling, the structural envelope is more constrained than the headline lot size suggests — once you subtract setbacks, easements, landscaped area requirements, and any tree preservation, the actual buildable area is usually 35-45% of the block. We map that early in the feasibility stage so you're designing to what's actually allowed, not what looks possible from the title plan. Foundation cost band on most McMahons Point blocks: $45,000–$80,000.
Planning Controls in McMahons Point
McMahons Point is zoned R3 Medium / R4 / B4 mixed with R3 Medium Density pockets. North Sydney Council controls FSR, height limits (typically 8.5–9m), site coverage, landscaped area minimums, and setbacks. For a secondary dwelling, the binding constraints on most 200–450m² blocks here are: front setback (around 4.5–6m), side setbacks (1.0–1.5m articulated), rear (3–6m depending on lot depth), and landscaped area (usually 35–40%). Buildana's design team works to those numbers from the first sketch — no late re-design when council comes back with comments.
McMahons Point Build Economics
McMahons Point sits in the $3.2M–$6.5M price band, which is the framing for any granny flat decision. On a 200–450m² block here, the build-versus-buy maths usually favours a granny flat for rental yield or family accommodation, with payback inside 8–11 years on $700–$950/week rental. Free Buildana feasibility runs the numbers against your actual block before any commitment.
Building to Suit McMahons Point
McMahons Point's R3 Medium / R4 / B4 mixed zoning, 200–450m² blocks, and 1880s–1940s heritage housing stock set the design context. For a secondary dwelling, the practical implications: secondary dwellings need to feel intentional, not bolted-on — proper roof line, matching materials, real privacy from the main house. Buildana's design phase resolves all of this before you commit to construction pricing.
Realistic McMahons Point Timeline
End-to-end timeline for a granny flat in McMahons Point, lodgement-realistic: 10-15 business days for CDC. Add 2-3 weeks for documentation pack assembly before lodgement (BASIX, geotech for Class M (sandstone) / H–E (harbour fall), contour survey, hydraulic). Add 1 week for Construction Certificate post-approval. Construction runs 10-16 weeks once CC issues. Buildana provides a dated programme in every contract, not a vague "12-18 months" range.
Builder's Take on McMahons Point
The trap on McMahons Point granny flats: treating the 60m² SEPP cap as a goal rather than a ceiling. A well-planned 45m² 1-bedroom often rents for 80% of the full-size 60m² — with $40K less build cost. The rental yield actually improves. Size the build to the use, not the cap.
Separate meter is non-negotiable. Without it, rental income gets murky (who pays for electricity?) and lease compliance becomes a fight. McMahons Point granny flats should be metered as a separate supply to the main home — $2.5K–$6.5K extra, saves five figures of dispute over a 10-year rental period.
