Home Extensions in Constitution Hill
Home Extensions done properly
ORT Construction Group builds home extensions in Constitution Hill 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 Constitution Hill 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.

Questions
Home Extensions in Constitution Hill, answered
Can we stay in the house during a Constitution Hill extension?
Often yes, depending on scope. Many Constitution Hill 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 Constitution Hill?
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 Constitution Hill projects combine an extension with renovating the existing rooms so the finished home reads as one space rather than old and new.
