Are you in need of more space at home?

There are many reasons that you may need an extra room in your home, whether it’s a master suite extension, a granny flat, a patio, a garage, or more.

At DeKing Decks, we love helping Aussie families make the most of the space on their property, working with the landscape and existing home to create seamless additions. In this blog, we’ll look at some bedroom extension ideas for growing families.

Why are Brisbane families choosing to extend their bedrooms?

  • Has the family outgrown the current home? New baby on the way?
  • Is the family coming to visit? Or a family elder moving in?
  • Are your teenagers needing separate bedrooms before they get too crabby?
  • Do you want additional space to create an Airbnb?
  • Are you dreaming about a new, spacious master bedroom?

Here are some ideas for that new bedroom addition or home extension …

Stand Alone Addition

Have you considered having an extra room in your home as a separate building to the family house, located to the side or the rear of the block? This option may work well for parents coming to live with you, or giving older teenagers a little more space and independence whilst still being at home. These bedroom additions are also multifunctional, so they could be used as a home office, music room, child’s play room, man-cave, she-shed, crafting room or media room, the possibilities are endless …

Combine Rooms

Another functional idea to create an additional bedroom for the home is to steal some space from the existing rooms in the home. Maybe there is one large room that could be divided into two with a wall? You may have two neighbouring rooms that a builder could borrow some space from each to make a third room. This won’t increase the actual living area of the home, but it will create more rooms to suit your family’s needs.

Raise the Home

This option is not available for all homes, but if you live in a Queenslander or post war home then you may be able to raise the home and build underneath, which will create a lot more floor space. This could provide the opportunity to add an additional bedroom, bathroom, family room, home office, laundry or storage facilities.

Re-purpose an Existing Room/s

If there is a room in your home that is hardly used, then you might consider changing the purpose for that room. It might be that the formal living room is not used much, as the family mostly uses the more casual family room. What a cheap and easy way to add that additional bedroom to your home! There may be a few small changes needed to convert the formal living room to a bedroom, like the addition of a wardrobe, lighting and power points, relocation of door entries and the like.

Rear or Side Home Extension

Building a home extension to the rear, side or front of the property is another great idea that will give you additional space in the home, which could be used for those additional bedrooms.

Garage Conversion

Converting the garage is one of the more affordable bedroom addition ideas. If you have sufficient land, you could build another garage to replace the one that you have converted or construct a carport as a cheaper alternative.

Converting the garage will provide a significant amount of additional livable floor space to the home. This space is not only great for bedrooms, but also another living area, home office or gym. You could move the home office to the garage conversion and create a new bedroom in the old office space. The ideas are endless …

Second Storey Addition

Another common way to add additional bedrooms is to create a second storey to a home. The second storey may just be for that new master bedroom you have been dreaming of with an ensuite, walk in robe, and a parent retreat as well.

If you need a lot of extra living area, you could double the floor space of the home if you added the second storey over the existing floor plan of the home.

Master Bedroom Inspiration

Above we have discussed how the additional physical space for the additional bedroom or home extension can be accomplished. Now we will give you some inspiration to create that perfect master bedroom, as this room is far more elaborate than just a bedroom.

contemporary master bedroom and bathroom

It is now common for the master bedroom to include built in robes and access to an ensuite bathroom. New homes now offer a master retreat which includes the bedroom, ensuite, walk in robe and a parent only living area. Master retreats are often separated from the rest of the home; sometimes, the retreat will take up the full upstairs of the house or a different wing of the home.

Contemporary master bedroom ideas include having a free standing bathroom in the bedroom itself, making it a feature as well as a functional room.

Really good master bedrooms make clever use of windows. The bedroom windows need to balance the need for privacy, natural light and ideally attractive views as well. Who doesn’t enjoy breakfast in bed while admiring the view? Bedrooms are no longer just functional, they can be a holiday in your own home and a pleasure to be in.

Frequently Asked Questions

What type of home extension adds the most value in Queensland?

Queenslanders love open-plan kitchens and living areas that seamlessly integrate with outdoor decks or patios. Buyers prioritise functional, breezy layouts that take advantage of the subtropical climate, combined with the practicality of an extra bedroom and a second bathroom.

What is the most expensive part of a home extension?

Structural work and foundations. Building a sturdy base, modifying load-bearing walls, installing support beams, and altering the roofline often consume the largest portion of your budget.

How much can you extend your house without planning?

In Queensland, you generally do not need planning permission for home extensions, as long as the project complies with the relevant codes.

What makes a master bedroom renovation look tacky?

Common culprits include overly sterile all-grey palettes, matching showroom furniture sets, and harsh, single-source overhead lighting. These choices strip the room of warmth and character.
