Home Extensions in Cremorne
Home Extensions done properly
If you are weighing up extending in Cremorne 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 Cremorne 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.

Questions
Home Extensions in Cremorne, answered
Can we stay in the house during a Cremorne extension?
Often yes, depending on scope. Many Cremorne extensions are built while the family stays in the existing part of the home, with the work zone separated and access managed.
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 Cremorne?
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 Cremorne projects combine an extension with renovating the existing rooms so the finished home reads as one space rather than old and new.
