Design, documentation & manufacturing

Before we get started we offer a complimentary one hour consultation either in person at our office or via the phone or Zoom (depending on your location). This meeting will allow you to get to know us and establish a broad design brief for your project. With this briefing information we can then provide costing, timing and design advice for your particular needs on your proposed site.

Fairweather Homes has a four step design & delivery process which will take you efficiently through to the completion of your new home with our approach to modular prefab construction. Once you are ready to proceed, our four-step process will commence.

Step 1D**

  • A registered builder (or approved owner builder) will need to be engaged by the owner and a building permit obtained to commence construction

Cost information

Each project is unique and will therefore be costed differently.

Completed building costs start at around $3,100 per square metre plus GST for an average 3 bedroom home on a flat site (updated January 2022).

Please note that 2020 to 2022 has seen escalations in the cost of building materials and supply shortages resulting in average 10% to 30% increase in the cost to build. These increases may continue so we are not able to make any confident long term projections of building cost at this time.

Final build cost will vary depending on type of building, finishes, complexity, site conditions, level of finish & detail, location & inclusions.
