Home Extensions in Curl Curl
Home Extensions done properly
ORT Construction Group works with Curl Curl 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 Curl Curl 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
- 1
Site visit and brief
We walk the home with you, discuss what the extension needs to achieve, and look at the existing structure.
- 2
Scope and quote
You receive a written scope and price covering structural works, framing, fit out and coordination.
- 3
Documentation
We work alongside your designer, engineer and certifier, or point you to the approvals your project needs.
- 4
Construction
Demolition, structure, framing, lock up and fit out are delivered by one team on an agreed program.
- 5
Completion
We finish, clean down, walk the works with you and close out any items before handover.

Local considerations
Planning home extensions in Curl Curl
What we check first
Salt air shortens the life of untreated fixings and some timbers, so we specify stainless or galvanised fixings and durable materials.
Homes in the area
Homes across Northern Beaches include coastal homes, many on sloping sites exposed to salt air, where material choice matters. We look at the existing structure, site access and levels in Curl Curl 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 Curl Curl property during the site visit.
Questions
Home Extensions in Curl Curl, answered
What does an extension quote include?
A written scope for the Curl Curl 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 Curl Curl extension?
Often yes, depending on scope. Many Curl Curl 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 Curl Curl?
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 Curl Curl projects combine an extension with renovating the existing rooms so the finished home reads as one space rather than old and new.
