The first step to building a granny flat is an enquiry. When you call or email us, we will send you a free information pack so you get a better understanding of what we do. From there, our qualified builder will inspect your backyard free of charge to check the area and discuss your needs and requirements. Our sales representative will then send you a fee proposal, which outlines the necessary requirements for your granny flat as well as its inclusions and overall price.Read More
Once you have accepted the terms and conditions of our fee proposal, provided us with a 10.7 planning certificate (formally known as 149 Certificate) from council, a sewer diagram and you have paid a deposit, we will organise for a surveyor to carry out a site survey on your property.
Once we have received your survey our qualified Inhouse design team will then draw up a concept floor plan and organise a personalised meeting to sit down with you to ensure your needs are met and any design alterations are made.
Once you are happy, we will proceed to start your approval with a private certifier or via council.
Once your completed approval has been issued by a Private Certifier or Council, we will ask you to sign a Fair Trading Home Building Contract and organise your Home Owner’s Warranty. We will invite you in for a meeting to select all the materials and colours for your granny flat from our wide range of selections available in our showroom.Read More
We will schedule your project to start and order all materials you have selected for the build.
We will then be on-site organising earthworks, excavation and piering to prepare for the slab.
You will be appointed a site foreman who will guide and update you throughout the construction until the handover is complete.
At Inhouse, we know that this investment is important to you and we do our best to finish construction as soon as possible while not compromising the quality of your building. Your brand new granny flat will be completed within 12 -16 weeks.
