Granny & Co Homes


Come check out one of our built granny flats!  We feel the best way for you to understand the quality and detail that goes into our work is to see for yourself. To give you peace of mind about you’ll also have the opportunity to talk with one of our many happy clients.

At Granny and Co Homes we pride ourselves on our range of inviting, high-quality customisable Architect-designed small home solutions. Our expertly-created house extensions and granny flats will improve the value of your property and ensure your home suits your changing lifestyle needs.

Our granny flats and house extensions are Architect-designed. 

Inviting, healthy, happy homes. This distinctly challenges the old-fashioned stigma of granny flats that resemble a backyard bungalow or home extensions that look like cheap add-ons and fail to add value to the home.

Fully customised to suit your needs, site and budget, giving you total flexibility in how you choose to use your new space. 

Our homes are built to a high standard, we don’t cut corners and we typically build to a better than the original home.

Whatever your requirements, lifestyle needs or taste, we have a design and floor plan to suit.  From simple 1-bedroom options to 2 & 3-bedroom (and more), loft living designs, luxury chalets, ambulant designs, and so on… choosing Granny and Co Homes means you can make the changes that are necessary for creating the perfect small home solution for you. 

If you find a design that doesn’t quite fit your needs, speak to us about customisation, it’s this difference that separates us from the rest.


One of the key differences between Granny and Co Homes and pretty much everyone else in the industry is that we encourage and assist our clients in by fully customising our designs to suit their needs. Choose from our great range of standard designs and then modify them to suit your needs, site, budget, and so on… With our guidance this brings out great results.

What things are considered during the design process? What can I modify? And how will it affect the cost? Will I be penalised for making changes to the design?

We want our clients to be happy with our product and service and consequently we care about the end-result. For this reason we offer a comprehensive design service that takes into account many variables during the design process including things such as:

  • How the granny flat can best fit onto your site
  • What plan improvements should be made (to suit your needs), this includes layout, accessibility requirements, 
  • Council regulations 
  • Site-specific design and structural alterations 
  • Building on flood-affected or bushfire prone sites
  • How to maintain privacy
  • The overall presentation (it needs to look inviting)
  • Flow between interior & exterior areas
  • Window and door sizing and placement (to ensure you have good natural light and cross-ventilation… these things are
  • vital for a healthy home)
  • Building materials
  • Thermal performance
  • Lighting and power layout, and so on. 
  • Our kitchens are custom-designed by our expert Cabinetmakers. 
  • You will also have the opportunity to customise wardrobes and cupboards to maximise storage. Additional storage is vital in a small home especially for those who are downsizing.
  • Can be incorporated in the roof space or via over-height cupboards if needed.


In summary, almost anything can be modified. We recommend that this be done during the design process so we can best work with your budget and present you with a fixed price contract. We have standard prices for our designs; modifications are priced in writing and the cost of your granny flat will be adjusted accordingly. The process is transparent and we make an effort to itemise modifications so that our Clients can choose the changes they require. This is part of our service, there are no hidden fees.
