“We’re a practice that has focussed on delivering high quality residential projects since 1994.”


Utz Sanby Architects is an award winning practice focused on delivering high quality residential projects. Established in 1994 we have a reputation for delivering great design, service and buildings. We are are passionate about design that enhances the lives of our clients, resulting in a positive change to how they live.

We provide a full architectural service for the duration of a project, from initial concept to completion, covering the following progressive stages:

  • Initial sketch designs
  • Submitting a Development Application (DA) to council
  • Design development
  • Preparing contract documentation
  • Tendering and negotiation
  • Contract administration

Because the design and construction process can be daunting, we endeavour to communicate, educate and assist clients throughout the process, so that the experience of the design and build is both rewarding and satisfying.

Additional services that we provide include:

  • Pre-purchase site visits – for advice regarding the development potential of a site, in order to help make an informed decision prior to purchase.
  • Feasibility studies – including: analysis of brief and budget; assessment of council constraints; preliminary opinion of probable cost, which may include initial conceptual design.
  • Interiors and furniture selection – our full architectural service includes selection of internal finishes, colours, tiles, lighting, sanitary and tapware and door hardware. We can also advise on the selection of furniture, fabrics, blinds and lighting.
