A duplex in Putney works on the larger blocks away from the river, but the waterfront premium shapes the call. This riverside Ryde suburb on the Parramatta River runs 550 to 850m2 blocks against a lower 580m2 duplex minimum, so many clear it. On a $2.4M to $4.5M market, rising past $5M for river frontage, an inland block suits a duplex while a river-fall block often makes more as a single home.
Where a block has substantial fall to the river, suspended slab engineering is needed, which two dwellings only make more expensive. The ground is Wianamatta Shale with sandstone outcrops, so footings and the slab are engineered to suit, and Heritage Conservation Areas over the village core are checked first.
What I would check first on your Putney block: the area against 580m2, the fall to the river, and the heritage status, 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.

Inland duplex vs river-fall single
Putney blocks run 550 to 850m2 against a 580m2 minimum, so many clear it.
An inland block suits a duplex; a river-fall block often makes more as a single home at the $2.4M to $4.5M-plus market.
Fall, shale and heritage
Substantial fall to the river needs suspended slab engineering, worse when split into two dwellings.
Wianamatta Shale with sandstone outcrops means footings engineered to suit, and the village heritage core is checked first.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Feasibility covers the planning side and the financial side. Yes-or-no on whether the block supports dual occupancy under City of Ryde Council controls, plus indicative end values, build cost, and likely yield. The point is to kill bad sites before you spend on design — not after. Dual occupancy floor plans designed for your Putney block — attached or detached configuration, vehicle access, private open space, and full City of Ryde Council compliance.
⏱The Putney construction phase. Fixed price, programmed, supervised. Full approval management: Statement of Environmental Effects, plans, reports, and all supporting documentation lodged with City of Ryde Council or private certifier. We handle RFIs and conditions. CC follows. Construction follows a tight programme: dual slabs in one mobilisation, paired frame stand, simultaneous lock-up, then trades rotate between sides for fit-out so no day is lost waiting on availability. The schedule is engineered, not optimistic.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Both dwellings handed over with individual Occupation Certificates. Subdivision lodged for separate titles. Separate metering installed. 6-year structural warranty per dwelling.
