The average Australian house is 186.3 metres squared (and climbing). 4 bedroom homes are also rising in popularity, though currently the most common house layout in Australia is a three bedroom home. Around 44% of all Australian homes are 3-bedrooms, while just under one in every three Australian houses has four or more bedrooms. This is a drastic increase in the popularity of 4-bedroom homes from the 90s, where 3-bedroom homes accounted for more than half of all Australian dwellings.

4 bedroom homes are the largest homes that you can still find at reasonable prices. The average cost to build a 4 bedroom home is between $2,000-$4,000 per square metre. Realistically, this puts the range anywhere between $230,000 to the low millions. There are a many factors which will impact the overall cost of buying or building a 4 bedroom home such as location, land, materials, furnishings, taxes and legal fees.

House plans and designs for 4 bedroom homes are very versatile. They will heavily depend on the type of building – i.e. how many stories, if it has a granny flat, bathroom numbers, the general size, land block, et cetera. A popular rule of thumb is that houses should have around 55-65 square metres of space per person. This ensures that the house will not feel too crowded and individuals can freely occupy the space.

In Australia, single story homes are the most common layout. To accommodate this, a very popular trend for four bedroom houses is to have the master bedroom on one end of the home, separated by the kitchen and living/dining room(s) from the three smaller bedrooms, which are usually grouped together at the end of a hallway. However, this is one design of many.

Choosing the right house plan for a 4-bedroom home can feel quite daunting. The abundance of choice makes sorting through possible plans a tedious and time consuming task. To help narrow down some of the best options, here is a list of the best 4 bedroom house designs and layouts in Australia tailored to each home type.

8. Detached

One unique style of home design that has been gaining traction lately is the detached model. With the rise in popularity of tiny homes, people have become inspired to keep multiple mini homes on their property rather than one large house.

This allows you to have all of the privacy of a 1 bedroom or 2 bedroom house without losing the space to house guests or other family members. It is also much more affordable than rebuilding or renovating an existing home. Whether you choose a kit home, prefab home or even a shipping container home, there are numerous benefits in having multiple self-sufficient houses on your property.

7. Relocatable/kit homes

If you still want the benefits of a traditional house for an affordable price, you might want to consider a kit home. Kit homes or portable buildings are a type of prefabricated buildings which arrive on the home disassembled. You will have to build the house yourself (or with the help of contractors) once the pieces arrive, but the overall cost is much lower than a traditional home.

A duplex is a residential home divided into two completely independent units. These units share a wall and nothing else.
