Home Extensions in Hornsby
Home Extensions done properly
ORT Construction Group works with Hornsby homeowners on extensions that add real living space: opening up the rear of the house, adding a bedroom or bathroom, extending a kitchen, or creating a covered indoor outdoor area that gets used year round.
Extension work in Hornsby 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 Hornsby, answered
What does an extension quote include?
A written scope for the Hornsby works, the structural and framing components, allowances where selections are not final, and clear exclusions so you can compare fairly.
Can we stay in the house during a Hornsby extension?
Often yes, depending on scope. Many Hornsby 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 Hornsby?
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 Hornsby projects combine an extension with renovating the existing rooms so the finished home reads as one space rather than old and new.
