Home Extensions in Arcadia
Home Extensions done properly
ORT Construction Group builds home extensions in Arcadia where the existing house needs more usable space rather than a full rebuild. That covers ground floor extensions, additional living areas, extra bedrooms, kitchen and rear extensions, and the structural alterations that tie new work back into what is already there.
From first site visit to handover on a Arcadia extension you deal with the people running the build, not a call centre. Progress, variations and next steps are confirmed in writing as the job moves.

Local considerations
Planning home extensions in Arcadia
What we check first
Sloping blocks change footing depths, step-downs and stormwater, so levels are surveyed before anything is priced.
Homes in the area
Homes across Hills District include larger brick homes built from the 1980s onward on bigger blocks with room for outdoor living. We look at the existing structure, site access and levels in Arcadia before pricing, so the quote reflects the actual house.
Council approval
Some single-storey extensions can be approved as complying development through a certifier, while others need a development application. It depends on the lot, zoning and any heritage or bushfire controls. We confirm the approval pathway for your Arcadia property during the site visit.
Questions
Home Extensions in Arcadia, answered
Is the carpentry done by your own team?
Yes. Framing, structural alterations and fit out carpentry are done in house, which keeps set out accurate and keeps the program moving.
Do you handle approvals for extensions in Arcadia?
We work alongside your designer, engineer and certifier and can advise what your project needs. We coordinate the construction side so the documentation and the build line up.
Do you do extensions and the internal renovation together?
Yes. Many Arcadia projects combine an extension with renovating the existing rooms so the finished home reads as one space rather than old and new.
Can you extend to create indoor outdoor living?
Yes. Wide openings, covered alfresco areas and level transitions between inside and out are common parts of the extensions we build.
