A granny flat is a self-contained, secondary dwelling built on an existing property, typically designed to provide independent living quarters. Originally coined due to their common use as a living space for aging parents or extended family members, the term “granny flat” has evolved to encompass a variety of purposes.
These flats have become popular not only among homeowners wanting to house family members but also among property investors looking to maximize the return on their real estate by adding additional rental space. While granny flats can be either attached or detached from the main house, they remain part of the same property title and often include essential features like a bedroom, kitchenette, dining area, living room, and bathroom/laundry.
What Are The Types Of Granny Flats?
Granny flats come in various types, each catering to different needs and preferences. The most common types include:
1. Detached Granny Flats
Detached granny flats are standalone units separate from the main house. They offer maximum privacy for both the homeowner and the tenant or relative living in the unit. These types of granny flats are ideal for those who need a separate living space but still want the benefits of being close to the main house.
2. Attached Granny Flats
Attached granny flats are physically connected to the main house, typically through a shared wall or door. They offer a balance between proximity and privacy, as they allow easy access to the main house while providing independent living spaces. These are ideal for multi-generational families who want to stay close but still maintain a level of separation.
3. Garage Conversion Granny Flats
A garage conversion involves transforming an existing garage space into a fully functional granny flat. This option is often a cost-effective way to add a secondary dwelling without having to build an entirely new structure. Garage conversions can be a great solution if you already have an underused garage space and want to maximize its potential.
4. Basement Granny Flats
Basement conversions into granny flats are another practical solution for homeowners looking to maximize space. A basement granny flat offers the benefit of utilizing existing square footage, though it may require significant renovation work, particularly in terms of lighting, ventilation, and moisture control.
5. Loft Granny Flats
Loft granny flats are built on the upper levels of a home, typically in the attic or on the second floor. These units can offer a unique and cozy living space with an open-plan design, though they may require structural modifications to accommodate the needs of a fully functional granny flat.
6. Studio-Style Granny Flats
Studio-style granny flats are compact, single-room units that combine living, sleeping, and cooking areas in one open space. These flats are perfect for individuals or couples who don’t require a lot of extra room but still want the privacy and independence of their own space.
7. Custom-Built Granny Flats
Custom-built granny flats are designed and constructed specifically to suit the needs and preferences of the homeowner. These units can be designed in a variety of layouts and sizes, from luxurious, multi-bedroom apartments to simple, one-room units. Custom granny flats allow for complete control over the design and features of the space.
How Big Is a Granny Flat?
Granny flats are typically smaller than the main residence but can vary in size depending on location and local regulations. On average, granny flats range from as small as 150 square feet to as large as 800 to 1200 square feet. The size of the unit will be influenced by factors such as zoning laws, the available land area, and the intended use of the flat. Smaller units may be suitable for single occupants, while larger units can accommodate small families or guests.
How Much to Build a Granny Flat?
The cost to build a granny flat can vary greatly depending on several factors, including the size, design, location, and whether it involves a new structure or a conversion. According to HomeAdvisor, building a granny flat typically costs between $40,000 and $125,000, with the average cost being around $82,500. This price can increase depending on the complexity of the build, materials used, and local labor costs.

Can I Build a Granny Flat on My Property?
Yes, you can build a granny flat on your property, but it is subject to local zoning laws and regulations. You’ll need to check whether secondary dwellings are permitted in your area, as some neighborhoods may have restrictions or specific requirements. In addition to checking zoning laws, you will also need to obtain the necessary permits, ensure your property has adequate utility connections, and adhere to building and design regulations. HOA rules may also influence whether or not you can build a granny flat, so it’s important to do thorough research before starting the project.
Do I Need To Acquire Permits For Building a Granny Flat?
Yes, acquiring permits is typically required when building a granny flat. Most local governments require building permits to ensure that the construction meets zoning, safety, and code regulations. The specific permits you need will depend on your location and the type of granny flat you’re building, and may include permits for the structure, plumbing, electrical work, and utility connections. It is essential to check with your local authorities or council to ensure that you meet all legal requirements and avoid fines or construction delays.
Important Aspects to Consider When Building a Granny Flat
1. Easy Access
When designing a granny flat, it’s essential to ensure easy access for future residents. The path leading to the flat should be convenient and not intrude on your existing living space. Consider how individuals will enter the property—whether through a dedicated pathway, a separate entrance, or a private driveway.
2. Maintained Privacy
To ensure privacy for both the main house and the granny flat, proper planning is key. Consider the placement of windows and doors, and face them away from the main house to avoid direct views into each other’s spaces. You might also want to create separate entrances that don’t intrude on the main dwelling’s privacy.
3. Maintained Security
Security is another important aspect to think about when building a granny flat. Both the main house and the granny flat should have proper security measures, such as locks, outdoor lighting, and possibly even a separate alarm system to ensure the safety of both properties.
4. Landscaping
Landscaping plays a vital role in maintaining a functional and visually appealing environment. If you plan to have tenants, consider low-maintenance options like artificial grass or hedging. Proper landscaping also helps enhance privacy and security, while providing a pleasant outdoor space for both the main house and the granny flat.
How Much Does a Granny Flat Add to Property Value?
Building a granny flat can significantly increase your property value. Depending on location and demand, adding a granny flat can boost the value of your property by 20% to 30%. This increase in value makes it a smart investment for homeowners looking to maximize their property’s worth, whether they choose to rent the granny flat out or use it for family purposes. The extra living space can also make the property more attractive to future buyers.
