Quick Answer
A duplex in Gledswood Hills costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Camden Council approvals, construction and subdivision under one fixed-price contract.
Gledswood Hills Dual Occ. — Feasibility to Handover
A duplex in Gledswood Hills is often not feasible, because the modern estate lots are small and most fall short of the Camden 450m2 minimum with room for two dwellings. This master-planned premium new release runs 2010s contemporary homes on 350 to 550m2 R2 blocks, and on a typical estate lot the honest answer is that the block is too compact to split for a Torrens-title duplex. The area is the first thing I check, because the numbers rarely work on a compact estate lot.
Where a rare larger lot clears 450m2 with genuine room for two dwellings a duplex is feasible, but most estate blocks do not, and the newer stock means a single home is usually the right call. The Gledswood Homestead heritage on the southern edge adds a check near it. Being newer, there is usually no asbestos to strip.
What I would check first on your Gledswood Hills block: whether it clears the 450m2 minimum with room for two dwellings, any heritage near the homestead, and the realistic scope. That decides the direction.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you honestly whether it is a duplex site.

How It Works
From First Call to Final Key
A duplex is really a feasibility problem wearing a construction outfit. Before anything else, we verify your Gledswood Hills block against Camden Council's LEP — lot size, frontage, FSR, landscape area. If it doesn't stack up, you find out in a week, not after 3 months of design.
⏱Design runs dual from day one. Two dwellings, one coherent streetscape, party-wall acoustics and fire rating built into the structure rather than bolted on. The plan accommodates R2 Low Density predominant zoning without looking like two mismatched houses sharing a fence.
⏱Approval and construction get sequenced together. Slab pours are choreographed so the trades show up once, frame up both sides, and keep rolling. Two separate meters, two separate services, but one crew, one programme.
⏱Handover is dual. Both dwellings walked at the same time, both OCs in the same issue, both titles subdivided before settlement. You leave the final inspection with the option to live in one and rent the other, or to sell both.
