Residential Builder Tips: A Step-by-Step Guide to Building a Granny Flat

13 March 2020

The process of building granny flat is complicated and involves many different groups. Construction planning is a process of identifying activities and resources required to make the design a physical reality and we’ve outlined the basic workflow that guides planning, permitting, inspecting, occupation and maintenance. Building your new home is exciting, especially when you understand how the process works. Below are several residential builder tips that will guide you into building a granny flat.

Rigorous Planning

The first action to take in building granny flat is contacting the local council authority to provide you with the specific regulations and compliance requirements for your area. Your first step is to find the right design. If you’re planning a build, there might be other things to think about water, electricity and other services, any hills or slopes and existing features that you want to retain.

Necessary Technical Details

Before starting on building your granny flat, contractors must first determine what standard designs are best suited for your block. They must prepare the site details by conducting soil test and site survey. They should also be ready with the floor plan layout, cost estimate, lifestyle requirements, design essentials and budget and feasibility of construction.

Tender Acceptance

Once the contour survey has been completed the design team will plot the selected design on the contour survey. This is an essential part for building granny flat since this includes the tender acceptance signed by clients and the company representative and the contract plans.


All granny flats must be constructively designed to be practical, functional and affordable and to suit most properties. A preliminary design and elevation from the information must be created and gathered, some homeowners opt for the standard designs. Once all the planning is in place you’ll be given a contract to sign and this means you are well on your way to turning your vision into a reality. Designs will be normally submitted to council at this point and you can sit back until planning permission is approved.


Among those that needed to be approved and agreed upon are architectural drawings for building granny flat, structural engineer’s drawings, pay long service levy.
