The Granny Flat Experts. Professional Sydney Granny flats are what we create, for new homes, old homes and all other requests. If you are thinking of building a granny flat within your property there are a number of things to consider. By checking out our Granny Flat Questions area, you can get a better understanding of what is involved when building a second residence or granny flat.

When it comes to housing, Sydney is at a bit of a disadvantage. The city is in high demand, and with a population that's constantly growing, the market for houses is getting more and more competitive. This is especially true for families who are looking for a larger home.

While many people might think that the only solution is to move out of Sydney altogether, there's actually another option: building a granny flat. Granny flats have been growing in popularity over the past few years, and for good reason. Not only do they provide an extra source of income, but they're also a great investment opportunity.

There are a few reasons why building a granny flat is such a smart investment. For one, Sydney's population is aging, and as people get older, they often need more space. A granny flat can provide them with the extra room they need without having to move out of their neighbourhood or into a nursing home.

Granny flats are also popular among families who have adult children living at home. By building a granny flat on their property, these families can provide their children with some independence while still keeping them close by.

Granny flats are a great way to add value to your property, and they can be rented out to tenants when you're not using them yourself. This makes them an excellent investment opportunity, especially in today's competitive housing market.

So if you're thinking about moving to Sydney or if you're already living in the city, consider building a granny flat. It might just be the smartest decision you have ever made. How big can you build?

Building a granny flat can be a very wise investment in terms of property wealth and property value.

Can I put a granny flat on my property?

The short answer is yes, but there are a few things you'll need to take into account.

Most councils have laws that regulate the size and type of secondary dwellings on a property. For example, some councils only allow granny flats if they're located within the boundaries of the primary dwelling, while others stipulate a maximum size or restrict certain building materials. It's important to check with your local council before starting any construction.

What size granny flat can I build?

The maximum floor area for a granny flat is 60sq.m under Complying Development (Where a Private Certifier issues the approval). This is calculated from the external corners of the granny flat.

Some Councils allow 60sq.m calculated from the internal walls resulting in a slightly larger overall floor area. To achieve this, the project will have to be approved by Council via Development Application (DA). Depending on the site parameters, it is permissible to have a porch, alfresco and attached garage in addition to the 60sqm internal floor area.

Will a granny flat add value?

Granny flats will add to the capital value of your home and will likely result in a higher sale price. In most cases, the rental return from the granny flat will turn a property from a negative-geared investment to a positive-geared investment depending on the value of your loan and the rental return in your suburb.

Backyards are considered by some to be ‘wasted real estate, hence why so many property owners are constructing granny flats to make use of their land. Granny flats are a great investment on existing properties given that the price of land in Sydney is relatively high.

Do you need planning permission for a granny flat?

The answer is YES. There are two ways to achieve approval for your granny flat. The first is through a Private Certifier (Complying Development Certificate or CDC), and the second is through your Local Council (Development Application or DA). CDC approval is the faster and more cost-effective way to obtain approval. It eliminates a lot of the Council’s ‘red tape’ and will save a lot of time and money.

Can a granny flat be attached to the house?

A granny flat can be attached to the house given that the adjoining wall is constructed in accordance with the minimum fire-rating level. There are other factors to be considered when attaching a granny flat to a house which may affect the design and overall cost.

Am I allowed to have more than one granny flat on my property?

The answer is NO. Each property is only allowed to have one primary dwelling (house) and one secondary dwelling (granny flat)
