Building Design Practice, Established in 1991
Provides a personal and friendly building design service, which includes the preparation of draft concept sketches from your scratch drawings, dream picture collections, written requirements, cut and pastes etc through to complete working drawings and reports for council Development Application (DA) submission.

Communication and understanding are the keys to making your new home design or renovation a success so we listen and provide practical guidance in a positive supportive manner.

Geoff Riordan is an Accredited Building Designer, while his wife Robyn Sharrock assists and provides Feng Shui design advice when requested.

Building Design documentation for new homes, renovations, multi-unit residential developments and industrial complexes has changed dramatically in the last five years. This is due to the continual upgrading of Local Council and State building sustainability. Large amounts of additional information and reports are required by Council and State government to complete a DA.

We prepare reports and applications or provide the option to minimise costs by pointing out which reports and applications you can do yourself.

Our creation of ‘Custom Computer Designed Plans’ with 3D modelling makes it easier for clients to visualise their project, simplifies the design process and reduces the time taken to finalise designs.

It is an exciting time and it is important that a design suits your individual requirements, lifestyle, environment, budget, Council regulations and State BASIX energy requirements.

Living and working in a regional area means we can provide contacts for Consultants, Builders, Surveyors, Engineers, Certifiers and Landscape Gardeners, when required. All this helps when it comes to getting the project under way.

So if you are starting from scratch, renovating or just need advice call us for expert and up-to-date advice.

Our initial consultation is free so that we can get to know you, explain our design process and answer any questions you may have.

When the design draft/s concept has been agreed upon, we produce architectural plans suitable for local council Development Application (D.A.) approval and tendering. Our knowledge of the local council requirements helps ensure a reasonably smooth passage through this stage.
