Second-Storey & Rear Additions in Voyager Point
A home extension in Voyager Point designs toward the river — the waterfront setting on generous 600 to 900m² blocks rewards wings that open the living to the Georges River the original homes under-used.
On the lower river-edge blocks, the flood mapping is checked before floor levels are set. The Class H junctions are engineered, and the 1980s-2000s fabric is largely clean.
At the $1.1M to $1.4M median, extending keeps the premium setting upsizing could never replace.

The wing faces the water
Voyager Point's river setting is the premium — and the extension should serve it: living and alfresco opened toward the water on blocks with genuine room.
The quiet waterfront character is exactly why extending beats moving here.
Flood and clay handled
The flood mapping is checked on the lower blocks before floor levels are set, and the Class H junctions are engineered.
The flood check and the junctions are both costed up front.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Walk through your Voyager Point home with our designer and structural engineer. We measure, photograph, and check the bones — footings, frame condition, roof structure. The cost estimate that follows is grounded in what we found, not a generic per-m² number. Our designer works with your existing home's layout — connecting new living areas to existing rooms, matching materials and roof pitch, and maximising natural light. You approve floor plans and 3D renders before we proceed.
⏱The Voyager Point construction phase. Fixed price, programmed, supervised. Most rear extensions in Voyager Point qualify for CDC — cleaner, faster, no neighbour notification. Second-storey additions typically need DA through Liverpool City Council because of overshadowing and privacy assessments. We choose based on your design, not on what's easier to lodge. Extension built from new footings to completion — connecting structurally to your existing home. Class H soil design managed. Temporary weatherproofing maintains liveability where possible.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Walk through the completed extension, confirm finishes, collect your OC. Six-year structural warranty covers all new work including the junction with your existing home. Maintenance guide provided.
