There are many reasons to get a master bedroom or ensuite extension in your house. Primarily, people add an extension to improve the value of the home. While that is a fantastic idea, you can’t expect it to bring you the best returns.

Any kind of house extension has to be reasonable. For instance, adding a bathroom to take care of the occupancy issues. Maybe you want to add a new master bedroom or en suite because the family is growing. If you have enough space, you should consider these.

With that being said:

The house extension costs for a master bedroom can range anywhere between $1,500 to $2,000 per square metre. Certain factors will determine the overall expense:

• The material consideration. Is it a brick or timber house?
• The design consideration. If you’re also looking for renovations, it will cost extra.
• The floor level. If you’re getting one above the ground floor, the cost will double.

Considering that a master bedroom is the most luxurious room in the house, you could spend around $100,000+ for the construction.

Generally, extension costs per square metre remain the same, regardless of what you aim to build. It applies to a bathroom, en suite, or bedroom. All that differs are the materials and other similar aspects.

If you plan to change the floorplan of the house or room, the cost will increase:

• You will need an engineer’s report, which can cost anywhere around $200 to $1,000. The cost will depend on the time it consumes and the complications of the plan.
• You need to get the council’s approval and meet all criteria and protocols. There will be an expert like a drafter and an architect. Usually, it costs $1,000+ to get done with these formalities. A building permit costs extra, around $700 – $1,000.
• For any home renovation project or extension project that costs more than $12,000 (which it will), you will need insurance. The Home Warranty Insurance could cost around $1,000.

So, depending on your requirement, an ensuite can cost:

• Around $10,000 to $20,000 for a budget-friendly addition.
• $20,000 to $30,000, even $40,000 for a mid-value ensuite.
• $30,000+ for a premium-grade addition.

To find out more, you can use the home extension costs calculator. It can help you get a precise quote by understanding your material requirements, among other things.

When people consider home extension costs, they only consider certain things. You considered the professional fees, building fees, material fees, insurance, and other formalities. However, there are often many other extra things that you would have to consider:

• For instance, if you hire an interior designer for the room or ensuite, the cost will double.
• Similarly, the insulation of each room costs $5,000+
• Painting the house or the room can cost anywhere between $1,000 to $20,000+

Therefore, it is always a good idea to take the higher end of the budget or quote as your minimum cost.

So, let’s assume an average room house extension cost in Australia is $50,000 to $90,000. Then, you should take $90,000+ as a budget, or $100,000 to be safe. Anything that you save will be a plus for you.

Similarly, an average ensuite extension can cost around $20,000 to $50,000. So, take $50,000+ under consideration.

The cheapest way to cut down the extension costs per square metre are:

• Ground-level constructions. These are the baseline. Because the second storey extension costs double the amount. If you are looking at building extension costs, that could be a fortune.
• Try to see if you can get things done with the renovation extension costs. These generally cost way less than a full-fledged owner-builder extension costs. In most cases, even half the cost of the actual extension project.
• Finally, keep the designs simple. Forget about interior designs. If you have a square or rectangular room, it will save you a lot of money. Simple constructions are easier and cost less.
• If you are using a brick base house, and considering the double story extension costs, try to go with lighter material. For instance, a timber extension for the top could help you cut down many expenses on the house made of bricks.

Typically, for a $1 million worth house, adding a room can increase by $100,000. So, that is generally lower than what you’re going to see in the list below:

• Adding A Bathroom Or Ensuite: Anywhere between 10% to 15% increment in value.
• Adding A Bedroom: Around 15% to 20% increment.
• A Master Bedroom: 20%+

The lower value increment is because the houses that already cost a fortune won’t manage to enhance the value much. That value increment is also for a simple room addition.

If you employ other things like interior designs, landscaping, and such, you can marginally increase the price of your house.

Truth be told, there are many other ways for you to increase the value of your house. If your objective is to enhance the value to sell it, you can employ interior designs, landscaping, repair, glazing and much more. They will be more cost-effective and improve the value by a similar percentage.

However, they will also decrease over time as they wear out or go out of trend. So, this idea is only good if you’re looking to sell your house. If you want to permanently increase the house’s value, home extension projects are best. Granny flats have also become quite popular as home extension projects in Australia. You can try those out, as well.

Remember that it is worth getting a home extension for a master bedroom or ensuite if there is a need for one. If you have a spacious house, they are worthwhile. However, if you already have a clustered house, it might not be the best action.

Hopefully, you received a good idea of the cost impact and how much would the master bedroom and ensuite extension cost you. So, go ahead and make a valuable decision.
