W.P. O'Brien & Co.

Step 1

From your initial enquiry we will arrange an informal site visit to conduct a feasibility assessment of your project.

Step 2

To proceed with design & preparation of plans, a Preliminary Agreement will be presented and agreed on.


Our commitment to provide a quality design requires an investment in time and our fee for this service will vary depending on the size of your project.


The design package involves a site meeting and consultation with our designer to discuss your needs, from which  you will be presented with a preliminary floor plan and elevations.  Although not a complete set of plans, it will become the blueprint of your Development Approval/Complying Development Approval if you wish to proceed.


Once these are produced a preliminary cost budget can be prepared.


If the budget is acceptable and you wish us to proceed, the final plans & associated documentation will be prepared and presented to you for final checking prior to submission to council.


During this phase, and depending on your council & type of project, professional services may be required (survey, shadow diagrams, geotech reports, engineering etc) prior to lodgement of the DA. On submission, a tax invoice will be forwarded to you for  all costs incurred including council fees paid on submission.

Step 3

Once approved, a firm quotation will be presented to you taking into account the council conditions of approval, the specific engineering details and any other requirements imposed.


Step 4

If the quotation is acceptable a contract will be drawn up, agreed on and signed.
