So, You’re Looking at Renovating a Post-War Home?

July 2025 Update

Some people feel that post-war homes don’t have much going for them. It is true that — from a design perspective — they can sometimes appear quite plain.

But there’s something inherently appealing about these homes, not necessarily in their original form, but in their potential. With the right approach from an experienced registered architect, they can be transformed into functional, contemporary spaces that meet the demands of modern living.

Perhaps it’s because their shortcomings are well-known, and after decades of use, we now have clear strategies for addressing them. Each home also tells a different story, shaped by the era in which it was built and the people who lived in it. That uniqueness is part of what makes renovating these homes so rewarding.

Most importantly, post-war homes typically have ‘good bones’, a solid structural base that lends itself well to renovation. Whether you’re planning to reconfigure internal layouts, improve energy performance, or add more space, these homes provide a strong foundation to build upon.

Let’s take a look at the key considerations when renovating a post-war home.

An Overview of Post-War Homes

As the name suggests, post-war homes refer to properties built in the decades following World War II.

In the years immediately after the war, there was a shortage of skilled labour and building materials. As a result, homes from the 1950s and 60s were typically modest in size and construction — often featuring two bedrooms and a small enclosed sleep-out. Many were built by owner-occupiers, which contributed to their functional but often uninspired designs.

These homes were commonly constructed from weatherboard or brick, and in some cases, a combination of both. Their layouts prioritised efficiency over architectural flair, which is why they can appear basic by today’s standards.

Over time, design expectations evolved, and by the 1980s and 90s, homes had grown in size and complexity. However, even newer builds from this era still carried over some of the limitations of their predecessors — particularly in terms of insulation, orientation, and interior flow.

Post-War to 2000s Homes Pros and Cons

While these homes often come with their fair share of challenges, they also offer a number of advantages that make them worth considering for renovation.

Advantages:

• Solid construction – Many features, quality materials such as hardwood frames, copper plumbing, and durable brickwork.

• Renovation potential – Their relatively simple forms and layouts make them highly adaptable to contemporary upgrades.

• Desirable locations – These homes are often found in well-established suburbs with good access to amenities.

• Good orientation – Many were built with thoughtful orientation to capture breezes or sunlight, even if the interiors need reworking.

Disadvantages:

• Poor energy efficiency – Most lack adequate insulation and ventilation, making them hot in summer and cold in winter.

• Compact floor plans – Small kitchens, narrow hallways, and limited storage are common.

• Dated or bland design – Interiors often feature low ceilings, small windows, and limited natural light.

• Layout inefficiencies – Circulation spaces are often poorly planned, which affects their functionality.

• Moisture issues – Poor sealing can lead to mould, mildew, and dampness, particularly around windows and external walls.

Improving the Energy Efficiency of a Post-War to 2000s Home

Improving the energy performance of these homes is often one of the most important and rewarding aspects of renovation. These houses were typically built at a time when insulation, glazing performance, and energy ratings were not a priority. As a result, they often struggle to maintain comfortable indoor temperatures without heavy reliance on heating or cooling systems.

Renovating provides an opportunity to significantly improve thermal comfort and reduce energy bills. Common upgrades include:

• Installing high-performance insulation in ceilings, walls, and under floors

• Replacing or retrofitting windows to improve glazing and seal air leaks

• Improving cross ventilation through strategic window and door placement

• Reorienting or redesigning living areas to maximise natural light and passive heating or cooling

• Upgrading roofing materials or adding reflective insulation to reduce heat gain

These changes not only contribute to a more comfortable living environment but can also help your renovation achieve a higher NatHERS (Nationwide House Energy Rating Scheme) star rating — now a growing expectation in the Australian housing market.

Options for Renovating Post-War Homes

Despite their limitations, these homes often hold far more potential than people realise.

Many are built on timber stumps, making them ideal candidates for being raised or reconfigured. And although their interiors may be modest in size, the layouts are often flexible enough to support a significant transformation. With the right design approach, these homes can evolve into bright, open, and contemporary living spaces, all while retaining their original character.

In fact, what they lack in flair, they often make up for in renovation flexibility. Their locations, usually within established, well-connected suburbs, add even more long-term value to any upgrade. Whether you’re extending, reconfiguring, or rebuilding underneath, the opportunities are extensive.

The key to a successful outcome is design, not just in terms of aesthetics, but also in how the home functions. A renovation should improve liveability, comfort, and connection to outdoor space.

If you’re living in a post-war to 2000s home that doesn’t meet your lifestyle needs, or you’re sitting on untapped potential, it might be time to rethink what your home could become.

The good news? All four major strategies for increasing space in a home are suitable for this era of housing, and we’ll explore each one next.

Reconfiguration and Refurbishment

This is often the first, and most impactful, step in transforming a post-war home. Even without increasing the footprint, reworking the existing layout can vastly improve how the home functions.

Updating the internal configuration can:

• Improve natural light and ventilation

• Create better flow between living spaces

• Remove awkward transitions and dead zones

• Support modern lifestyles through open-plan design

Refurbishment typically includes upgrades to flooring, lighting, fixtures, and finishes, allowing you to bring the look and feel of the home in line with contemporary expectations.

Extensions

These homes are prime candidates for extensions. Whether it’s expanding the kitchen, adding an extra living space, or creating a private master suite, an extension can solve the limitations of smaller footprints without needing to relocate.

Their relatively simple rooflines and construction methods often make it easier to tie in new work seamlessly with the old.

Raise and Build Underneath

Raising and building underneath is a particularly effective strategy for homes built on stumps. Whether you’re looking to double your floor area, gain legal ceiling height, or create a dual-living arrangement, this approach can unlock serious potential.

It’s also a great way to improve views, natural light, and airflow, especially in sloping suburbs or areas prone to flooding.

Pavilion Addition

On the right block, a pavilion-style extension can be a stunning architectural feature. This approach allows you to introduce a distinct, modern space, often connected by a breezeway or glass link, that complements the original home while creating new lifestyle zones.

Pavilion additions work well for creating guest quarters, home offices, poolside entertaining areas, or private retreats separated from the main living spaces.
