Building design
for Sydney homes
since 1998
Extensions & additions, new homes, heritage conservation areas, complex sites.
Every project gets the design attention you deserve.
As seen on Grand Designs Australia
Greg designed a tiny house on the northwest coast of Tasmania for the program: a difficult site, a tight budget, and a lot of recycled material.
Building Design Services, Sydney Inner West
Renovations, extensions, alterations and new homes. Thoughtful, practical design for the way you actually live — and documented properly so your builder can price it and build it.
Residential Design
Federation, Victorian, Art Deco, California bungalow, mid-century. If your home is a heritage item or sits in a conservation area, the rules are different — and so is the design approach that gets approved.
Heritage & Conservation Areas
Cafes, restaurants, offices and retail fitouts, warehouses and cold storage. Functional, compliant, and designed around how the business actually runs.
Commercial Design
DA, CDC or exempt? Clear advice on which pathway applies to your property, what the controls actually allow, and how to keep an application moving.
Planning & DA Advice
Start with an Exploration Package — $795
Most people spend months — sometimes years — trying to work out what is actually possible with their home. Between council controls, unclear budgets and conflicting advice, it is easy to feel stuck before you start.
The Exploration Package answers it. For a fixed $795, you get a written review of your site, the council controls that apply to it, and a realistic assessment of what can be built there — including which approval pathway you would be on.
Turned around within a week. Faster if you are up against an auction.
"He attended a midweek open-for-inspection and, within an hour, delivered a comprehensive report… Although we were ultimately unsuccessful in purchasing the property, Greg's prompt and thorough response gave us clarity about our constraints and enabled us to participate in the bidding process with much greater confidence."
- John, Marrickville.
It is a low-risk first step that tells you where you stand before you commit to anything — and if you decide to go ahead, the work carries straight into the design.
Buying rather than renovating? Plenty of clients use the Exploration Package before they bid, to find out what a property will actually allow. More on pre-purchase advice.
