Home Extensions in Round Corner
Home Extensions done properly
If you are weighing up extending in Round Corner rather than moving, ORT Construction Group can take the project from the existing home through demolition, structural works, framing, lock up and fit out to completion, with one team responsible for the result.
Extension work in Round Corner usually starts before construction does. We look at what the existing structure can carry, what needs engineering, and where services run, then price the build against a scope you can actually compare.

Local considerations
Planning home extensions in Round Corner
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 Round Corner 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 Round Corner property during the site visit.
Questions
Home Extensions in Round Corner, 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 Round Corner?
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 Round Corner 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.
