Home Extensions in Werombi
Home Extensions done properly
ORT Construction Group works with Werombi 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.
From first site visit to handover on a Werombi 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.
Process
From enquiry to handover

Scope and quote
You receive a written scope and price covering structural works, framing, fit out and coordination.

Construction
Demolition, structure, framing, lock up and fit out are delivered by one team on an agreed program.

Completion
We finish, clean down, walk the works with you and close out any items before handover.

Local considerations
Planning home extensions in Werombi
What we check first
Flood and bushfire mapping can set minimum floor levels or material requirements, so we check the planning certificate first.
Homes in the area
Homes across Macarthur include newer estates and established family homes on larger blocks, plus semi-rural acreage. We look at the existing structure, site access and levels in Werombi 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 Werombi property during the site visit.
Questions
Home Extensions in Werombi, answered
Can we stay in the house during a Werombi extension?
Often yes, depending on scope. Many Werombi 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 Werombi?
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 Werombi 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.
