Requirements

Building a granny flat requires the subdivision of your property lot. Density codes, which vary by area, determine the space requirements for the lot. Granny flats must be smaller in higher density codes and vice versa. Granny flats of all sizes require planning, building and council approvals.

 

Requirements for a three-bedroom granny flat

Three-bedroom granny flats are often relatively large. This makes it harder to get approval in areas with higher density codes.

 

Requirements for a four-bedroom granny flat

Four-bedroom granny flats are typically the largest granny flats built, making them suited to areas with lower density codes. 

 

 

Benefits

Three or four-bedroom granny flats can provide benefits in the form of increased property value, rental yield and flexible use of rooms. 

 

Benefits of a three-bedroom granny flat

Three-bedroom granny flats offer increased space, privacy and flexibility compared with two-bedroom granny flats. More bedrooms provide the opportunity for more tenants or repurposed rooms. Three-bedroom granny flats give a solid boost to property value thanks to their size and bedroom count. 

 

Benefits of a four-bedroom granny flat

Four-bedroom granny flats offer the highest level of privacy and flexibility among granny flat types. They can accommodate the highest number of tenants or the most rooms for repurposing. Their size and high number of bedrooms make them well-suited to being sharehouses. Four-bedroom granny flats add the largest amount of property value due to adding the highest number of bedrooms to the property. 

 

 

Designs

Three or four-bedroom granny flats typically have an open-plan kitchen and living room area with separate areas for the bathroom and laundry. Here at Granny Flats WA, we have an array of ready-made granny flat designs, or we can create a custom design just for you!

 

Three-bedroom granny flat designs

Three-bedroom granny flat designs typically allocate a more significant proportion of their space to bedrooms than the kitchen and living area. Outdoor areas are commonly incorporated into their designs.

 

Four-bedroom granny flat designs

Four-bedroom granny flat designs have less space dedicated to the open kitchen and living area. The higher number of bedrooms can leave each bedroom smaller than it would be for a two or three-bedroom granny flat with the same square footage. Four-bedroom granny flats often include an outdoor or alfresco area.
