A duplex in Ramsgate Beach costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Bayside Council approvals, construction and subdivision under one fixed-price contract.
Duplex Builder in Ramsgate Beach
A duplex in Ramsgate Beach depends on where the block sits, because the beachfront changes everything. Lots run 450 to 800m2 against the 600m2 Bayside duplex minimum, so the larger ones clear it. On a $1.9M to $3.0M market, rising to $4.5M-plus on the beachfront, an inland block suits a duplex while a direct-beachfront block usually makes more as a single home.
The ground is Botany Sands, so footings and the slab are engineered to suit, and coastal salt-grade specifications apply on beachfront builds, setting the materials. R3 along The Grand Parade adds a medium-density option near the water, and the inter-war and post-war stock carries asbestos, stripped under licence.
What I would check first on your Ramsgate Beach block: the area against 600m2, the distance to the water, and the salt-grade specs, because those decide between a duplex and a single home.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you honestly what makes the most of it.
Buildana manages the full duplex development process in Ramsgate Beach — from feasibility assessment and architectural design through to DA or CDC approval, and fixed-price construction to dual handover. One builder, one contract, two homes.

How It Works
From First Call to Final Key
We assess your Ramsgate Beach block — lot size (typical 450–800m²), width, R2 Low zoning, setbacks, FSR, landscaped area requirements under Bayside Council's LEP and DCP. Minimum lot for duplex: 600m² (Bayside DCP — R2 dual occupancy). You'll know viability before spending on design.
⏱Design phase covers unit layout, access, parking, private open space, and waste management for dual occupancy on your Ramsgate Beach site. You approve final plans before we move to lodgement.
⏱Duplex approvals get scrutinised harder than single dwellings — neighbour notification, overshadowing, privacy, traffic, waste. Our SEE addresses each on the front foot rather than reactively. Cleaner submission, fewer conditions, faster CC.
⏱Fixed-price construction of both dwellings from slab to keys. Class M engineered footings, frame, lock-up, internal fit-out, and external works. Weekly progress reports.
⏱Subdivision registration starts in parallel with final fitout so titles issue close to handover, not 6 months after. Buildana coordinates the surveyor and Bayside Council clearance — important if you're planning to sell one side immediately to fund the next move.
⏱Quality Promise
Our Ramsgate Beach duplex projects run from feasibility to subdivision under one builder. Fixed price, dual handover, full compliance.
