Let’s Meet Up
Next, we'll arrange to meet up either by phone or on site so we can see what you're hoping to achieve and discuss what's possible with your block and budget.
Initial Quote
After our catchup we'll get back to you with some figures on what your Granny Flat project will cost.
Customer Acceptance
If you are 100% happy with our initial quote we will arrange for another catch up, this time with our Designer so we can all get together and put those design ideas onto paper and move forward with our Design Process.
Design Process
Once you've signed the Preparation of Plans Agreement (PPA) and paid your deposit our Designer will get started on completing your plans. After this we meet up again to go over the design, make any tweaks and do any price adjustments.
Planning Approval
Ancillary Dwellings aka Granny Flats, require Planning Approval in WA, so our next step is getting all of the paperwork ready to submit to your local Shire for Development Approval.
Final Plans & Contracts
Off the back of your Planning Approval, we now get to work completing Final Plans, with Energy Report, Engineering and Certification before preparing the Building Contracts, and Homeowners Warranty Insurance. This is then sent out to you for signing.
Building License Permit
Once Contracts are signed we will move forward with gathering all of the documentation on your behalf to apply for your Building License Permit.
Selection Process
The next step is to finalise your selections for your new Granny Flat. Chances are you have made a lot of the selections already but here you will choose your finishes and colours.
Construction
Once we have received your Building Permit, we are ready to begin the construction stage. This begins with any demolition, site preparations and then moves onto the building process. Timeframe of construction for your Granny Flat is approximately 16-20 weeks.
Practical Completion
Now it's time for you to join us onsite to have a look around, inspect your new abode and if need be, identify any outstanding or incomplete items before we are ready for sign off and final payment.
Handover
Congratulations! Your project is complete. Final payment has been made and the keys are yours. You'll also receive your warranty documents and a Customer Feedback form to let us know how we did.
