Extension & Renovation Design for Existing Homes
Distinct Innovations designs home extensions, first-floor additions and major renovations across Greater Sydney and selected NSW regions. We begin by understanding the existing home, site constraints and planning controls, then develop new spaces that improve layout, functionality and indoor-outdoor connection. The aim is for the extension to feel integrated with the original house rather than added as an afterthought.

Client Feedback
Castle Hill House: "Loved our experience with Luke & Distinct Innovations! Luke guided us through the process right to the end. We're delighted not only with the design but also Luke's ability to make his vision come to light. He was in regular contact with the builder to ensure the accepted design materialised. He kept in regular communication with us too, to ensure we were comfortable as the build progressed, making several insightful suggestions along the way. We've got a bespoke, luxury home now, which sets it apart. Thank you!"

How We Plan and Design Home Extensions & Renovations
Designing Around Your Existing Home
A successful home extension should improve how you live, solve existing layout problems and feel connected to the original house.
Before design begins, we review the structure, roof form, floor levels, access, setbacks, overshadowing, privacy, drainage, BASIX requirements and planning controls. This establishes what can be designed, approved and built.
With more than 30 years’ experience across Sydney, we design rear extensions, first-floor additions and major renovations that improve space, natural light, circulation and indoor-outdoor living while responding to the existing home and site.

Home Extensions & Renovations FAQs
Do I need a DA or CDC for a home extension in Sydney?
The approval pathway depends on the property, zoning, planning controls and proposed work. Some home extensions and first-floor additions may qualify for a Complying Development Certificate, while others require a Development Application through the local council. We review the site, setbacks, building height, floor space ratio, heritage status, bushfire risk and other relevant controls early to identify the likely approval pathway.
What should be assessed before designing a first-floor addition or major renovation?
The existing structure, roof form, floor levels, site access, privacy, overshadowing, drainage, streetscape and planning requirements should be reviewed before the design is developed. A surveyor, structural engineer, BASIX assessor or other consultant may also be required. Early investigation helps establish what can reasonably be designed, approved and built.
Do you prepare architectural drafting and approval documentation for extensions and renovations?
Yes. Distinct Innovations prepares concept designs and architectural drafting for home extensions, first-floor additions and major renovations across Sydney. Depending on the project scope, this can include DA or CDC drawings, Construction Certificate documentation, consultant coordination, council or private certifier liaison and NSW Planning Portal lodgement.
