Granny Flat

Detached or Attached granny flats, also known as secondary dwellings, offer a number of benefits and are becoming very popular with new home buyers and builders. Whether you’re looking to accommodate ageing relatives, growing children, or for investment purposes, Domaine offers a variety of granny flat options to suit your newly built home. Dual occupancy is another advantage, providing flexibility and additional living space.

To begin, we offer an array of single and double storey designed homes with the option to incorporate a one or two-bedroom granny flat design. Houses with granny flats enable families to have the security of housing on their own, without having to compromise on space or privacy. They also provide excellent opportunities for investment purposes and allow homeowners to rent out the space on the side. Discover our range of home designs that can incorporate an attached or detached granny flat.

Detached Granny Flats

Detached granny flats are a great option for an investment or a place for growing children to have their own space. Many people are opting for a house plan with a granny flat rather than building/buying a whole new home. Compared to the costs of a single-dwelling investment property, a granny flat is a much more affordable and convenient option. Benefits of a detached granny flat include:

  • Additional rental income, whether from tenants or travellers

  • Cheaper investment build

  • A place to have loved ones close whilst still having their own privacy

  • Just like an attached granny flat, a detached option will also add value to the resale of your home

All our home designs allow detached granny flats depending on your lot restrictions. 

Attached granny flats

An increasing number of new homebuyers with large families are looking for a housing solution that accommodates multigenerational living whilst still providing privacy for the occupants. The benefits of an attached granny flat include:

  • Greater economy and affordability

  • A place to have loved ones close whilst still having their own privacy

  • Ability to earn additional rental income if you decide to rent it out.

  • Finding a house with a granny flat for sale can be extremely difficult. Therefore, a granny flat will certainly enhance the resale value of your home

What is a Granny Flat?

A granny flat is a self-contained living space, typically built on the same block as an existing home. Designed to provide additional living space for family members, such as grandparents, teenagers, or adult children, granny flats offer a versatile solution for modern living. These units can also serve as rental properties, generating passive income for homeowners. Whether built as a separate dwelling or attached to the main house, granny flats often feature essential amenities like a kitchen, bathroom, bedroom, and living area, making them a practical addition to any property.

Benefits of a Granny Flat

Building a granny flat comes with a host of benefits for homeowners. Firstly, it provides additional living space for family members, allowing them to live independently while still being close to the main house. This setup is ideal for accommodating ageing relatives or giving teenagers and adult children their own home and space. Moreover, granny flats can be rented out, generating passive income that can help offset mortgage payments. They also enhance the value of a property, making it more attractive to potential buyers if the homeowner decides to sell in the future. With the ability to design granny flats to suit specific needs, whether for family use or as a rental property, they offer a flexible and valuable addition to any home.

Regulations and Compliance

Before embarking on the construction of a granny flat, it’s crucial to understand the regulations and compliance requirements in your area. In many cases, local council regulations will dictate the size, design, and location of the granny flat. Homeowners must also adhere to building codes and standards, covering aspects such as safety, accessibility, and energy efficiency. Working with a reputable builder who is well-versed in these regulations is essential to ensure that your granny flat is built to code and meets all necessary requirements.

Pricing and Cost

The cost of building a granny flat can vary widely, influenced by factors such as size, design, and materials used. On average, building a granny flat can range from $50,000 to $200,000 or more, depending on the complexity of the project. Homeowners should also account for additional expenses like land preparation, council fees, and other associated costs. It’s essential to work with a builder who can provide a detailed quote and help you understand the full scope of the costs involved, ensuring there are no surprises along the way.

Investment and Rental

Granny flats present a lucrative investment opportunity, especially for homeowners looking to rent them out to tenants. With the right design and location, a granny flat can generate significant passive income, helping to offset mortgage payments and increase the property’s overall value. When considering renting out a granny flat, factors such as rental yields, property management fees, and local market conditions should be taken into account. Additionally, homeowners must ensure compliance with all relevant regulations and laws related to renting out a granny flat, safeguarding their investment and providing a secure living space for tenants.

Is building a home with a granny flat the right option for you to generate passive income?

  • Looking for a multigenerational living solution that allows you to plan for the future growth of your family

  • Wanting to build an affordable investment or a place for guests to stay
