Licensed Custom Home Builder Whale Beach — Design & Construct
NSW licensed builder (Oliver Alameri) delivering fixed-price custom homes across Whale Beach 2107. Engineered slab for Class Hawkesbury Sandstone soil, BASIX 2025, 6-year structural warranty.
Quick Answer
A custom home in Whale Beach costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Northern Beaches Council approvals and fixed-price construction.
Custom Homes Designed for Whale Beach
A custom home in Whale Beach is an engineered oceanfront build in one of Sydney's most exclusive, secluded coves. The blocks run 600 to 2,000m2 with heritage beach houses and mid-century Sydney School modernist homes on significant sandstone fall, and at a $5M to $20M-plus oceanfront market the land and outlook justify a serious, considered design. This is a tightly held premium cove and it builds like one.
This is Hawkesbury Sandstone with very deep rock excavation running $80K to $180K-plus, so the substructure is engineered and priced honestly from the start, and bushland-fringe lots carry a BAL rating from 19 up to Flame Zone that drives the spec. A Heritage Conservation Area covers the cove and the direct beachfront sits in a Coastal Hazard zone, so the site controls shape the envelope before design. A home oriented to the ocean rewards the effort.
What I would check first on your Whale Beach block: the very deep rock and substructure, the BAL rating, and the heritage and coastal-hazard overlays. Those set the home.
We build these fixed-price, licence HBL 487805C. Show us your block and outlook and we will design to it.
Buildana's design-and-construct service covers everything — from initial design brief and land assessment through to council approval and fixed-price construction. One builder, one contract, one point of contact.

How It Works
From First Call to Final Key
We start with a site visit or showroom meeting to talk through what you want to build on your Whale Beach block. We'll review Northern Beaches Council's planning controls for 600–2,000m² lots with R2 Low zoning and give you a straight answer on budget and feasibility.
⏱Design starts with site analysis — sun path, prevailing breeze, neighbour overlooking, slope, view lines from each likely living area. The plan is drawn to that, not dropped onto the block. Two design options usually, sometimes three, then you pick the direction and we refine.
⏱Working drawings, structural engineering (Class Hawkesbury Sandstone soil design), BASIX certification, geotechnical report, stormwater plan and all certification documentation prepared.
⏱Most custom homes in Whale Beach qualify for CDC with a 10–15 business day turnaround. If DA is required through Northern Beaches Council, we manage the full submission and respond to any requests for information. Construction Certificate follows.
⏱Construction is run from a programme, not made up week to week. Trade sequencing is locked in advance so the slab cures into a waiting frame and the frame waits for nothing. That's how a 24–40 week build actually delivers in 24–40 weeks instead of running 60+.
⏱Walk through your finished home, collect keys, and move in. OC issued, defect-free inspection completed, 6-year structural warranty, and full maintenance guide provided.
