Home Extensions in Surry Hills
Home Extensions done properly
ORT Construction Group builds home extensions in Surry Hills 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 Surry Hills 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 Surry Hills, 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 Surry Hills?
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 Surry Hills 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.
