A granny flat, also known as a secondary dwelling, is a self-contained living space located on the same property as an existing home.

Many property owners are now exploring granny flats and secondary dwellings as a way to create additional accommodation on their property.
​

​
-
Airbnb accommodation
-
Short stay rentals
-
Guest accommodation
-
Rural tourism accommodation
-
Family and visitor accommodation
If you are considering an Airbnb granny flat or secondary dwelling for short stay rental purposes, our team can discuss suitable layouts, design considerations and project requirements for your property.
One of the advantages of prefabricated construction is the ability to significantly reduce onsite building time compared to many traditional construction methods.
​
Because much of the construction process occurs within our Adelaide workshop before delivery, onsite installation is completed far quicker than a traditional build.
​
Project timeframes will vary depending on approvals, site preparation, engineering requirements and design selections, however prefabricated granny flats provide a faster pathway to creating additional living space.
One of the most common areas of confusion within the granny flat industry is understanding exactly what is included in an advertised price.
​
Many advertised "starting from" prices can appear attractive initially, however customers later discover that important items required to complete the project may be additional costs.
​
Common exclusions can include:
-
Delivery
-
Onsite installation
-
Footings
-
Internal works and finishes
-
Engineering
-
Approvals
-
Site works
-
Service connections
At Inoutside, we believe customers deserve realistic pricing guidance from the beginning.
Every project is different, however our goal is to help clients better understand likely project requirements early in the process to avoid unexpected surprises later.
Every property is different and a range of factors can influence the design, approvals and final project cost.
​
These may include:
-
Site access
-
Soil conditions
-
Slope and retaining requirements
-
Council requirements
-
Bushfire overlays
-
Service connections
-
Delivery requirements
-
Design selections
Our team works with you to identify these factors early and help determine the most suitable solution for your site.
