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... If your home is a heritage item or is in a conservation area, the rules are different — and so is the 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 comprehensive report on your property, which includes: what you have now, the planning controls that apply, and what is realistically possible. It also gives you the approval pathway you would be on, a concept plan and indicative budget guidance.
It normally takes about two weeks. If you have a reason to need it sooner, just let us know.
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 is the first step in the design.
Buying rather than renovating? The same report, written to meet your auction deadline, so you can bid with confidence — and if you miss out on the house, the next report is half price.
