A granny flat in Coogee 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, Randwick City Council approval and fixed-price construction.
Coogee Granny Flat Construction — Fixed Price
Granny flat in Coogee delivers $850–$1,200/week driven by Coogee Beach premium. HCAs restrict siting on most older streets. Sandstone soil; suspended slabs on cliff-fall lots. Coastal salt-grade specs add $5K–$15K. Where compliant siting exists, build cost $260K–$420K.
For a secondary dwelling in Coogee, the economics are the framing question. Median price $2.8M–$6M; build cost on 250–600m² blocks scales by site conditions and specification. Class M (sandstone ridges) / H–E (cliff fall on coast) ground (extremely reactive clay) keeps foundations honest — $45,000–$80,000 band — and blowouts on that line are the single most common reason fixed-price contracts elsewhere don't stay fixed. Buildana itemises the slab, structural engineering, and geotech work upfront so you see the actual cost in the contract. R3 zoning in pockets of Coogee opens up dual occupancy potential — worth exploring even if you're not initially considering it.
Buildana manages the full granny flat process in Coogee — 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 Coogee?
Coogee is the LGA's signature beachside suburb — Federation cottages, inter-war heritage, mid-century apartments and contemporary on 250–600m² blocks fronting Coogee Beach. Heritage Conservation Areas cover most older streets. Sandstone-dominant with substantial fall to the beach. R3 along Coogee Bay Road and Carrington Road. Coastal salt-grade specs mandatory.
Coogee's established streetscape and median house prices of $2.8M–$6M reflect a premium location within Randwick. Building costs sit above the metro average, offset by stronger capital growth and rental returns. Transport access via Light Rail Randwick (2 km) connects Coogee to the wider Sydney network. Secondary dwellings on 250–600m² blocks deliver rental returns of $650–$1,000/week per week. CDC approval through a private certifier typically takes 10–15 business days. Class M (sandstone ridges) / H–E (cliff fall on coast) soil (extremely reactive) is standard for Coogee — Buildana includes engineered slab design in every quote.
Granny flats in Randwick deliver $650–$1,000/week typical, $850–$1,200/week on coastal-proximate lots in Coogee, Maroubra, South Coogee. Block sizes 350–700m² generally accommodate compliant siting on detached lots inland. Daceyville HCA precludes granny flats across the entire suburb. Coastal HCAs restrict placement on Clovelly, Coogee village, South Coogee, Malabar, La Perouse character streets. Sandstone soil; suspended slabs and substantial retaining on cliff-fall lots add $20K–$50K. Coastal salt-grade specs add $5K–$15K. CDC available outside heritage zones; otherwise full DA. Realistic build cost $220K–$380K for premium 60m²; $260K–$420K on cliff-fall coastal blocks.
Planning Controls — Randwick City Council
Randwick LEP 2012 & Randwick DCP 2013. R2 Low Density covers most residential streets: FSR 0.55–0.65:1, building height 9.5m, front setback 4–6m, landscaped area 35–40%. R3 Medium Density along Coogee Bay Road, Carrington Road, Belmore Road, Maroubra Road and Anzac Parade permits FSR up to 0.9:1. R4 High Density and B4 Mixed Use concentrated on the Anzac Parade UNSW corridor through Kensington and Kingsford, Randwick Junction, Coogee village and Maroubra Junction. Heritage Conservation Areas cover Daceyville (entire suburb), Coogee village, Clovelly, parts of Maroubra and South Coogee, Randwick Junction, La Perouse, Malabar and Kensington/Kingsford pockets. Tree Preservation Order LGA-wide. Sandstone-dominant soil with substantial cliff fall on the eastern coast from Clovelly through South Coogee to Malabar Headland — suspended slabs and substantial retaining standard, rock excavation $20K–$60K. Coastal salt-grade specifications mandatory across all coastal-facing builds (Clovelly, Coogee, South Coogee, Maroubra, Malabar, Little Bay, La Perouse). Aboriginal cultural heritage protocols apply on the La Perouse headland and parts of the Botany Bay foreshore. UNSW campus and Light Rail (Randwick line + Kingsford line) drive density along Anzac Parade. The new Randwick Health & Innovation Precinct (Prince of Wales Hospital, UNSW Health Translation Hub) is the LGA's signature strategic centre. Randwick Racecourse and Centennial Parklands frontage on the western edge of the LGA.

Building in Coogee — Local Context
Site & Ground Conditions in Coogee
Coogee sits on Class M (sandstone ridges) / H–E (cliff fall on coast) soil — extremely reactive clay. For a granny flat, that rules out the cheapest off-the-shelf slab designs straight away. and pushes engineered footings into the $45,000–$80,000 range on most 250–600m² blocks here. Geotechnical testing isn't optional — every Buildana secondary dwelling in Coogee starts with a borehole report so the slab and footings are sized to your actual block, not a generic spec. Skipping that step is how you end up with cracked cornices and sticking doors three years in. Drainage design matters too — overland flow paths on Coogee's topography can collect water against rear setbacks if the contour survey is sloppy.
Approval Timeline for Coogee
Realistic timeline for a secondary dwelling in Coogee: 10–15 business days for CDC if the design qualifies. Add 2–4 weeks before lodgement for documentation, BASIX certificate, geotech report, and survey if you don't already have one. Construction Certificate is issued separately before works commence.
Where the Money Goes on a Coogee Secondary dwelling
Cost breakdown for a typical secondary dwelling in Coogee: structure and frame around 30%, slab and foundations 8–14% (driven by Class M (sandstone ridges) / H–E (cliff fall on coast) soil), roofing and external 10–12%, services (plumbing, electrical, HVAC) 12–18%, fit-out (kitchen, bathrooms, joinery) 18–25%, and finishes (paint, tiles, flooring) 8–12%. The remaining 4–6% covers approvals, certifications, and site establishment. Buildana itemises every line so you see what you're paying for — no lump sums hiding margin.
Designing for the Coogee Streetscape
Coogee's housing stock is predominantly from the 1900s–1940s + apartments. Light Rail Randwick (2 km) from the nearest station. The local anchor is Coogee Beach & Wylie's Baths. For a granny flat, the streetscape question matters more than most builders admit — a brand-new double-storey on a street of single-storey 1900s–1940s + apartments weatherboards will draw council attention on bulk and scale, even if technically compliant. Buildana designs the front elevation to read appropriately for the street while modernising the floor plan and structure behind it. Materials palette, roof pitch, fenestration rhythm — all chosen to settle into the existing rhythm rather than fight it.
What Recent Approvals Show
Randwick City Council's recent decisions for Secondary dwellings in Coogee reveal a clear pattern — clean CDC submissions with correct setback dimensions on plan, BASIX matching the actual specification, and clear separation from the parent dwelling are clearing in 10-12 business days consistently. Sloppy lodgement adds 4-8 weeks of round-trip; clean lodgement doesn't.
Builder's Take on Coogee
Separate meter is non-negotiable. Without it, rental income gets murky (who pays for electricity?) and lease compliance becomes a fight. Coogee 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.
Rental yield on a Coogee granny flat typically sits around 8–11% gross — often stronger than the main dwelling in percentage terms. The $200K–$260K build returns $18K–$28K per year in gross rent. Even after expenses, it clears comfortably.

How It Works
From First Call to Final Key
Granny flats get underestimated. A lot of builders treat them as a kit-home product. We don't. Your Coogee block has a main dwelling, a driveway, service connections, trees, and neighbours — the secondary dwelling gets designed around those realities.
⏱The 60m² SEPP cap is not a suggestion. Every millimetre gets used — kitchen, bathroom, laundry, living, bedroom, storage — with the envelope tuned for Coogee's sun and prevailing breeze. Real rooms, not compromise spaces.
⏱CDC gets lodged through a private certifier the week design locks in. 10–15 business days later, slab starts. The trades sequence tight because the footprint is small — one plumber, one sparkie, one tiler, one programme.
⏱Handover gives you a genuinely rentable second home. Separate meter, independent hot water, standalone bathroom, full kitchen. Ready to lease on handover day, not a 'studio' that needs another $20K of finishing.
⏱Quality Promise
Coogee granny flat construction done to a schedule. CDC lodged, slab poured, handover complete — on one fixed-price contract.
