Top 7 Tips for Raising Post-War Homes

July 2025 Update

When people think about raising homes and building underneath, they typically think of Queenslander-style homes, but this can also be a great solution for renovating a post-war home.

Raising and building under the house means you can effectively double the size of the home.

Post-war homes can look amazing with the right renovation. Raising them and building underneath is one way to do this, as it can dramatically improve their livability.

However, a word of caution. This is an exercise where great design is vital. I’ve seen plenty of examples of homes that’ve been built under which the result of the project is far from satisfactory.

I’m not saying that every post-war home is a good candidate for being raised; some are better off with an extension instead.

Even if raising and building under is an option for your post-war home, simply raising it and adding a ground floor won’t guarantee a great outcome.

Here are some tips to consider before starting your renovation project.

1. Know What You Want and Why You Want It

If you’re frustrated with a lack of space in your home, chances are you have a good idea about what additional space you need. For example, if you have growing teenagers, you might need an additional bedroom or two.

However, the key is to focus less on what you think you need and more on your lifestyle and how your current home is limiting that lifestyle. We will take the time to understand your frustrations and needs, and then provide you with options.

2. When Raising Homes and Building Underneath, Connection is Vital

The temptation can be to think about the upstairs and downstairs almost as separate homes – but they are two parts of the whole. As such, they need to be connected.

So, what do we mean by connected?

Well, getting between the two is a good start. Are you going to have external stairs from an upstairs deck in addition to the internal stairs? If you have elderly people in the home, do we need to consider an elevator?

We must also consider how spaces interact with each other. Imagine, for example, if your main kitchen is upstairs but you intend to do your entertaining on a lower deck beside your pool. How will that work in a functional sense? These things need to be considered and planned for to ensure your home works in the way you need it to.

3. There May be a Better Option

If we consider the example given in Tip 2, you may have an idea of how you see each floor working, but design experts may be able to come up with a better solution.

We will consider all aspects of the project to create a design that’s going to best suit your budget and needs. It’s important to keep an open mind when it comes to the possibilities.

4. It Might be a Great Time for Some Upgrades

If we’re going to be raising your home and building underneath it, it might be a great time to restump your home if they haven’t been replaced in a previous renovation.

Post-war homes with timber or concrete posts can be a termite risk.

Steel posts are termite-proof and long-lasting, making them an attractive option. Restumping is actually not that expensive in the scheme of things, and can give you extra peace of mind.

Chances are, there are many poles under your home. Some of these are going to have to go to make way for rooms and open spaces. This will require steel beams (RSJs) to be installed to support the weight of the top part of your home. The design of your downstairs area needs to take this into account; the longer the span, the bigger the RSJ needs to be.

5. We May Still Want to Do Some Reconfiguration

Post-war homes often lack well-designed floor plans.

By reconfiguring the floor plan, we can open up spaces to create better natural airflow and let in more natural light. Natural light is great for your mental health, and also for lowering your running costs.

Changing the floor plan can really improve the livability of your home. For example, you may choose to have all bedrooms on one floor. You may wish to have a home office with a separate entrance if you work from home.

Which reminds me – sound insulation is an important consideration to keep the upstairs noise away from downstairs, and vice versa.

6. Do You Want to Reposition Your Home?

If we’re lifting your home, we can also move your home.

That’s right – we can reposition your home on the block if that better suits your lifestyle needs.

Now, we are not talking about putting it right on a fence line. But if you want to move it slightly forward, back or sideways to reconfigure your yard, that’s definitely doable.

This is a great option if you’re looking at adding a swimming pool but don’t have a large enough backyard. If you feel your home is too close to the street, or you want a larger front yard, moving your home may also be a viable option.

7. Preparing for the Project

If you decide to raise your home and build under it, then you’ll need to be prepared to move out of your house while it’s being raised. This is for safety reasons, as it’s unsafe to stay in the home while it’s not on stumps.

Most furniture will be able to stay in the home, but breakables like mirrors, fish tanks, vases, etc., should be packed away and/or moved until the raising/restumping part has been completed.

In many cases, this only takes a few weeks before you’ll be able to move back into your family home and enjoy the end result.
