A home extension in North Ryde costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, City of Ryde Council approvals, and construction under one fixed-price contract.
Second-Storey & Rear Additions in North Ryde
A home extension in North Ryde sits on land two growth engines keep re-rating. The Metro station is in the suburb and Macquarie Park's business district is next door, so the post-war and 1960s to 1980s homes on 600 to 900m² blocks carry strong rental demand and steady appreciation. At a $2.0M to $3.2M median, an extra bedroom is space now and income later, and extending beats trading up.
Method follows the era and the ground. Post-war stock extends best at ground level while later brick can go up with engineering, and the Wianamatta Shale soil generally behaves. Lots on the eastern edge fall toward the Lane Cove River, where sandstone can turn up in the dig, so we test before pricing groundwork on those blocks.
What I would check first on your North Ryde house: the era of the walls, the rear yard depth, and the sandstone if you are on the river-fall edge. Those set the build method and the budget.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Extension feasibility comes down to two things: what the existing structure can carry, and what City of Ryde Council will let you build. We assess both at the consultation — no point designing for a second storey if the slab can't take the load. Extension designed to integrate with your existing North Ryde home — matching roof lines, materials, and flow between old and new sections. Floor plans, elevations, and 3D renders.
⏱The North Ryde construction phase. Fixed price, programmed, supervised. All approval documentation prepared: structural drawings, BASIX, shadow analysis, stormwater, and statement of environmental effects (if DA). Lodged and managed through to Construction Certificate. Extension construction takes 3–6 months on average. Footings excavated and poured to match existing depth on Class M soil, frame stand, roof tie-in (most weather-critical phase), lock-up, then internal fit-out at the same standard as the existing house.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Defect-free inspection, OC issued, 6-year warranty on all new work. Junction between old and new sections waterproofed and warranted. Maintenance guide covers care of new and existing areas.
