A Granny Flat That’s Designed Just For You

Prefabricated granny flats come in various sizes and layouts to accommodate different needs and preferences. While traditionally thought of as small, one-bedroom units, modern granny flats can range from cosy studios to spacious two-bedroom retreats. The design possibilities are endless, allowing homeowners to create a space that suits their lifestyle and requirements.

Australian Made, For Australian Weather

Regardless of whether you’re looking to install backyard pods for guest accommodation or timber barns to run a business, all our modular buildings promise Australian quality. Our PreCrafted granny flats are designed and constructed locally, using materials specifically chosen for their durability in Australian conditions. Rest assured, your granny flat is built to withstand the elements and provide a comfortable living space for years to come.

Sustainable Granny Flat Solutions

At Greenspan, sustainability is at the core of everything we do. Our PreCrafted construction method minimises waste and maximises resources, ensuring that every detail of our buildings is carefully planned and crafted with millimetre precision. From sustainably sourced renewable plantation timber framing to handcrafting techniques in our Sydney-based factory, we prioritise environmental responsibility at every step. 

Uses and Applications

  • Additional Accommodation: Pre-built granny flats provide extra living space for extended family members, guests, or renters. They offer privacy and independence while still being close to the main residence.
  • Home Office: With more people working remotely, granny flats are increasingly being used as backyard offices. These dedicated workspaces offer a quiet and productive environment away from the distractions of the main house.
  • Rental Income: Renting out a granny flat can be a lucrative source of additional income for homeowners. Whether it’s a long-term rental or a short-term vacation rental, prefabricated granny flats can offer a convenient and flexible rental option.
  • Chill Out Areas: Granny flats are a fantastic solution for anyone looking to build a tranquil retreat away from their home. This could be used as a child’s playroom, a study zone or hangout for teenagers, or even as a cosy, welcoming space to entertain friends. 
  • Pool Houses: Granny flats offer the ideal solution for creating a dedicated space to relax and unwind by your pool, or for storing pool equipment. 
  • Backyard Studios: Create a flexible space in your backyard that can be used as a dedicated art studio, a space to practise your hobby, or for running a home business.

What is a granny flat?

A granny flat is a self-contained living unit, often built on the same property as a primary residence. It can be used for housing elderly relatives, as a rental unit, or for other purposes. Our prefab granny flats are designed to provide comfort and convenience.

Do I need council approval to build a granny flat?

In most cases, yes. Council approval is typically required for building a granny flat. However, regulations can vary, so it’s best to check with your local council before starting your build.

Can a granny flat increase the value of my property?

Absolutely. Adding a granny flat studio to your property can significantly increase its value. Potential buyers or renters often view a prefab granny flat as a valuable asset, whether for housing elderly relatives, generating rental income, or by creating versatile spaces like home office pods or art studios. Investing in a granny flat studio is a strategic way to boost your property’s market value and may lead to a quicker sale when it comes to selling.
