Do Your Research

There are numerous methods to build a granny flat. For help, talk to a builder or architect who has done it before. The basic idea is to build a platform or raised area on top of the foundation of your existing home, then add a weatherproof shell and any interior fittings and fixtures you need. Your granny flat should be separate from the main house.

Take Time Planning

It's easy to get caught up in the thrill of building a granny flat, and once you've made the decision, it can be tempting to move quickly and pick something that looks good to get things going. Or you may suddenly need a granny flat and are looking for a quick fix for your situation immediately. 

In either case, slowing down and giving the planning process more thought is important. Putting in a granny flat is a big job that you want to do right. It's important to spend time on this part of the process. It doesn't have to take a lot of time, but getting the basics right in the planning phase is key to your success in the long run.

Some things to think about during the planning stage are:

  • Where you are, in NSW, it's easy to apply for a granny flat, but other states have more requirements, and getting approval can be hard, so you'll need to consider this. If you live near the beach, your building plans and needs differ from those in a rural area in the middle of the country. 
  • Your space. How you plan and build your granny flat will depend greatly on how much space you have in your backyard or elsewhere on your property. Some questions to ask are: Is it easy to get to? Do you still want to give your kids more backyard play space? Can you build up to two stories if you need more space? Does your lot have any hills or other things that might make it hard to build on? What kinds of views do you want to avoid or get more of?
  • What the granny flat is for. The 'why' behind building a granny flat will also affect the design and plans. For example, there are better choices than a two-story granny flat if you want to use it to house older adults or less mobile family members. On the other hand, it could be the perfect solution if you want to rent out a smaller space. For people with special needs, you can also add extra parts and features to the design. 
  • Your budget. Everything, from the size you can build to the fittings and finishes you choose, will depend on how much money you have.
  • How will you make it work? Did you know that eco-friendly granny flats can be built? If you want your granny flat to be as sustainable as possible, think about this when planning it. Things like orientation, windows, insulation, and ventilation all make a building sustainable.

This seems like a lot to ponder, but one of the easiest ways to get through this process is to write down your end goal and a list of your non-negotiables. If you need to know how things like where you live or how much space you have will affect your plans, you need to find the right builder so they can point you in the right direction.

Find a Builder/Contractor

Once you have a basic plan for your granny flat, you may search for a builder to help you with the project. Choosing a builder with a good name and a lot of experience in the field is important. It's also important to look for someone who can adapt and think outside the box. Make sure to get quotes for different designs and price ranges so you can choose the best option for you.

Some things you can do to find the right builder for your granny flat are:

  • Choosing the right builder for your needs. For example, you don't want a builder who hasn't worked with people with special needs to design and build your elderly relatives' granny flat. 
  • Check their awards, reviews, and past projects to see if they have the experience and quality they say they do.
  • Talk to them and ask them questions to see how they answer. Are they kind, knowledgeable, and friendly? Building a granny flat will require a lot of talking, so make sure you and your builder can talk well.

Be Open to New Ideas

After you've found a granny flat builder and told them about your plans and ideas, it's important to keep an open mind and listen to what they have to say.  

Builders with a lot of experience, like us, who have built more than 1500 granny flats, can give you new ideas or suggestions for how to do things or reach your goals in ways you may have not thought of. 

That means you can stick to your list of must-haves, but being open to the advice of a seasoned builder will help you make the most of all the good ideas you have. 

Secure Permits and Approvals

Depending on the laws in your area, you may need to get several permits and approvals before you begin constructing your granny flat. The approval process can be complicated, so it's a good idea to hire an experienced building inspector to help you and deal with any problems. Before you start working, check with the local government to find out exactly what your project needs. 

Budget Properly

As with any building project, you could go over budget if something unexpected comes up. Figure out how much it will cost to build the flat. Then, put 10% or 20% more in your budget than that to ensure you have enough money for any surprises. This helps you avoid the problem of using too many capital letters.

Ask Questions

Not only is it fine to ask questions, but you should! Don't let something go if it worries you or you don't understand. You are the one who will have to live on your property with the granny flat.

Any good builder should be willing to explain the process in detail and work in a relaxed way. Our team wants you to feel comfortable enough to trust us and our experience, but we also want you to know everything there is to know about your granny flat so you can make decisions. There are no dumb questions, and we never want you to feel like you can't ask anything or that you're being ignored. 

Install Utilities and Fixtures

Once the unit is done, it's important to put in all the utilities and fixtures you'll need to use daily. This can include everything from lighting and heating to electrical outlets and plumbing. Leave a little space in the unit to add decorations later. If you need to, hire a plumber or electrician to finish the job. 

Make a Clever Design Choice

Granny flats are made to have a limited amount of space inside. Using round tables or building shelves into walls and dividers are smart ways to make the most of this space.

Keep Communication Open

The key to a happy and smooth home-building process is good communication. You should feel like you can talk about your worries, know your rights, and ask questions. Problems should be talked through instead of being ignored. This will ensure you feel like your rights are respected, understand the process, and solve any problems peacefully.
