Henley Home Builder — Custom Homes, KDR, Duplex
Licensed NSW builder (HBL 487805C) · Fixed-price contracts · Hunters Hill DA + CDC managed in-house
Henley is the small Parramatta River foreshore suburb of Hunters Hill — Federation/inter-war heritage on 500–1,200m² blocks with substantial fall to the river. Heritage Conservation Areas cover most streets. Sandstone-dominant with deep rock excavation typical.
Henley sits on Hawkesbury Sandstone bedrock ground, mostly under R2 Low Density controls through Hunters Hill Council. Existing housing stock is largely 1880s–1940s Federation/Victorian/inter-war heritage predominant (Heritage Conservation Areas cover virtually entire LGA) + premium contemporary infill, so older slabs, mixed-quality additions and pre-1990 fibro are all common — we plan for that before we quote.

Builder perspective
Building in Henley — what we actually look at first
Henley is a small run of streets on the Parramatta River, and a builder in Henley works to the same three constraints that govern the whole peninsula — just on a tighter, more intimate scale. Federation and inter-war heritage homes sit on 500–1,200m² blocks that fall to the river, with Heritage Conservation Areas covering most streets and the Henley wharf and foreshore setting the character. It's Hunters Hill quality without the harbour-tip price ceiling.
Sandstone is the governing fact. Rock sits close under most Henley blocks, so deep excavation and rock-anchoring have to be priced before design, and the river fall means substructure — not finishes — is where the budget goes. Heritage status shapes what's possible on the older stock, often steering a project toward sympathetic reconstruction rather than clean-sheet demolition, and river frontage brings the Foreshore Building Line into play. We read the heritage listing, pull the geotech and check the fall on the first visit, because on these blocks that's what sets the real number.

Why owners build with Buildana in Henley
Same six facts on every contract — we just write them down so you can hold us to them.
- NSW HBL 487805C, properly insured — every job runs on a fixed-price contract, scope locked before site start.
- Hunters Hill we own the council pathway — CDC for compliant lots, DA where the design needs assessment, either way it's our problem to solve.
- Consultants — structural, geotech, BASIX, RFS — coordinated under one Buildana project lead so the documents arrive in the right order.
- Demolition packages include SafeWork-licensed asbestos clearance and tipping fees — not stripped out of the headline price to look cheaper.
- Contract pricing built from a Rawlinsons-aligned BoQ — when council adds a condition, the cost impact is itemised in writing.
- Anchored on the amanah principle — the scope on contract day is the scope at handover. Local landmark: Henley shops + Henley wharf + Parramatta River foreshore. Train: Wollstonecraft (5 km).
Henley build economics
Indicative cost ranges for a Buildana build in Henley, benchmarked against the Rawlinsons Australian Construction Handbook 2026 Sydney baseline and adjusted for the local cost profile. Every figure is a starting point — a real feasibility shifts it by site condition, brief and finish spec.
| Build type | Indicative range | Spec assumptions |
|---|---|---|
| Single-storey custom home (200m² GFA, mid-spec) | $2,200–$2,650/m² × 200m² | Brick veneer, ColorBond roof, mid-tier joinery and finishes — Rawlinsons 2026 Sydney medium-spec baseline. |
| Double-storey custom home (300m² GFA, mid-spec) | $2,500–$3,100/m² × 300m² | Two-storey brick veneer, light-frame upper, ColorBond or tile, mid-spec finishes — first-floor adds engineering and access loadings. |
| Premium custom home (350m²+, full-brick or rendered) | $3,200–$4,800/m² × 350m²+ | Full-brick or rendered structure, hardwood or stone external, custom joinery throughout — Rawlinsons high-spec baseline. |
| Detached duplex (combined 350m² GFA) | $2,600–$3,300/m² combined | Twin-slab on separate footings or party-wall slab; independent services; BCA Vol 2 acoustic separation. |

Buildana lodges roughly two-thirds of Henley matters as CDCs and one-third as DAs. The split tracks the design: rectangular single-storey on a regular R2 Low Density lot is almost always CDC (effectively not applicable — hunters hill is overwhelmingly heritage-listed); anything with a non-standard setback, large extension on an existing slab, or duplex on 1,000m² under Hunters Hill DCP 2013 (highest in Sydney — heritage protection)+ lots is DA (14–20 weeks for a single-dwelling da — heritage referrals are routine) with fees of $2,500–$4,200 base for a class 1a residential da. Where the right pathway isn't obvious from the brief, our certifier and town planner sit on the design before the drafting starts.
CDC pathway
Private certifier · Effectively not applicable — Hunters Hill is overwhelmingly heritage-listed · no neighbour notification. Design must comply exactly with the Codes SEPP.
DA pathway
Hunters Hill merit assessment · 14–20 weeks for a single-dwelling DA — heritage referrals are routine · DA fees $2,500–$4,200 base for a Class 1a residential DA. Used where the design pushes a code limit.
Section 7.11 / 7.12 developer contributions in Henley: Modest (typically $10K–$20K per dwelling).
Henley site considerations
Site cost variability in Henley comes from two main drivers. First, soil — with Hawkesbury Sandstone bedrock ground the footing system has to be engineered to the geotech (waffle pod, stiffened raft or piered slab depending on the report). We never quote slab cost off a desktop assumption; the geotech goes out before contract. Second, the existing 1880s–1940s Federation/Victorian/inter-war heritage predominant (Heritage Conservation Areas cover virtually entire LGA) + premium contemporary infill housing stock means demolition variables — pre-1990 fibro requires a SafeWork NSW Class B asbestos licence and proper containment, and that's priced into the contract, not back-charged when the demo crew finds it.
Soil & footings
Class Hawkesbury Sandstone bedrock predominant (saw-cutting, rock-anchoring $40K–$140K above standard substructure on harbour-fall lots) / Class M Wianamatta Shale on ridge / Foreshore Building Line + Crown Lands referral universal on Lane Cove River and Parramatta River frontage reactivity drives waffle-pod, stiffened raft or piered slab — engineered to a real geotech, not a desktop guess.
Demolition
Pre-1990 1880s–1940s Federation/Victorian/inter-war heritage predominant (Heritage Conservation Areas cover virtually entire LGA) + premium contemporary infill stock means SafeWork-licensed asbestos clearance — priced into the contract upfront, with the clearance certificate before slab pour.
Flood & bushfire
Flood risk: very low. Bushfire risk: very low. Heritage exposure: high. We map your lot against each before quoting.

Book a site checkHenley build FAQs
The questions we get asked most often on a first Henley site walk.
- Can I build a duplex in Henley?
- Duplex feasibility in Henley depends on lot size and zoning. The minimum lot for dual occupancy under Hunters Hill Council's DCP is 1,000m² under Hunters Hill DCP 2013 (highest in Sydney — heritage protection), and R3 Medium Density lots in the suburb can support attached duplex or townhouse configurations. We run a feasibility check on title, zone, area, frontage and slope before quoting — no point designing what won't approve.
- What's the granny flat pathway in Henley?
- Granny flats in Henley are usually built under State Environmental Planning Policy (Affordable Rental Housing) 2009 — secondary dwellings up to 60m², CDC pathway, no DA required on most compliant R2 Low Density lots. Typical rental return is $580–$820/week (limited — heritage controls + foreshore restrictions tighten siting). The block needs minimum 450m², a primary dwelling already on it, and compliance with side/rear setbacks. Where the lot doesn't comply with SEPP, we lodge a DA with Hunters Hill Council.
- What soil class is typical in Henley 2111?
- Henley ground is typically Hawkesbury Sandstone bedrock based on the AS 2870 site classifications and geotech we've worked with in the suburb. That drives slab design — waffle-pod, stiffened raft or a piered system depending on the report. We never assume it; every Buildana build commissions a geotechnical investigation before slab engineering. The geotech report is yours to keep, regardless of which builder you use after.
- What does it cost to knock down and rebuild in Henley?
- End values in Henley sit in the $3.5M–$6.5M typical heritage; $5.0M–$15M+ harbour-front Woolwich/Hunters Hill peninsula range based on recent sales. A typical knockdown rebuild — demo, asbestos clearance, geotech, slab, frame, full mid-spec finish for a 200m² single-storey — runs $2,300–$2,850/m² × 200m² + $25–$45k demo as a Rawlinsons-aligned 2026 baseline. We benchmark every line to the Rawlinsons Australian Construction Handbook, not back-of-envelope figures. Send through your block address and we'll run a proper feasibility against what's actually achievable on the lot.
- Do you do extensions and renovations in Henley?
- Yes — ground-floor additions, second-storey adds, full-house renovations, kitchens and bathrooms in Henley. The complication on 1880s–1940s Federation/Victorian/inter-war heritage predominant (Heritage Conservation Areas cover virtually entire LGA) + premium contemporary infill housing stock is that you can't price an extension off the plans alone — we pre-investigate the existing slab, frame, roof tie-in and wet-area waterproofing before quoting. Surprises during demolition are the most common reason renos blow their budget; we eliminate that by inspecting first.
- How long does a DA take with Hunters Hill Council?
- 14–20 weeks for a single-dwelling DA — heritage referrals are routine. CDC through a private certifier is the alternative where the design complies with the Codes SEPP — effectively not applicable — hunters hill is overwhelmingly heritage-listed. Council DA application fees fall in the $2,500–$4,200 base for a class 1a residential da range. Buildana lodges either pathway and runs all RFI responses through to determination.
- Why does Henley cost different from a generic Sydney average?
- Henley tracks the Sydney metropolitan median build cost — there's no significant premium or discount on labour or materials in this suburb.
- How long does a custom home build take in Henley?
- From contract signed to handover, a single-storey 4-bedroom custom home in Henley typically takes 9–11 months on a CDC pathway, or 12–14 months if the design needs a DA through Hunters Hill Council. Add 4–6 weeks for double-storey. Pre-construction (design, engineering, BASIX, approval, contract) runs in parallel and adds another 8–16 weeks before site start. Buildana sequences both phases so the design effort and the approval effort don't sit waiting on each other.
