Thinking of Renovating an Older or Heritage Home? Start Here.

That initial excitement of deciding to renovate or restore an older home can quickly turn into overwhelm.

Where do you begin?

Who should you speak to first?

Will council allow what you’re hoping to do?

And how do you avoid the cost blowouts that are only exciting on Grand Designs?

If this sounds familiar, you’re not alone, and you’re not doing anything wrong. Renovating an older or heritage home is complex, and knowing where to start is often the hardest part.

As a Melbourne-based architect working specifically with older and heritage homes, I often see clients feeling unsure how to begin. This guide is intended to help you orient yourself – to understand what really matters early on, and how to approach the process with clarity rather than guesswork.

Is your home heritage-protected – or simply older in character?

Some older homes are protected by council through a Heritage Overlay. These controls exist to prevent the loss of buildings that contribute to Melbourne’s architectural and streetscape character.

This isn’t something to be afraid of. Heritage controls provide a framework – one that typically protects the original façade and ensures that any additions remain sympathetic in scale, form, and placement. Restoration, renovation, and extensions are all possible, provided they’re handled with care and intention.

Other older homes may not have formal heritage protection. But the absence of an overlay doesn’t mean the home has no value, or that it should be treated without restraint.

Older houses are a finite and increasingly rare resource. When their original character is respected and thoughtfully adapted, they often become highly desirable, long-term homes. For this reason, I apply many of the same principles to non-heritage homes as I do to heritage-protected ones – because they consistently lead to better outcomes.

The real questions to answer first

Before thinking about plans, layouts, or extensions, there are a few fundamental questions worth spending time on.

What do you actually need?

Clarity about what isn’t working in your home, and what you need it to do, gives the project direction.

It’s also important to think ahead. How might your needs change over the coming years? Growing children, working from home, changing routines – flexibility matters. A well-considered renovation should prevent the need to renovate again in five years’ time.

What can – and should – be kept?

If heritage controls apply, some elements will be governed by council. But equally important are the parts of the house you value and want to retain.

From a practical perspective, the more of the existing structure that can be kept, the more cost-effective a renovation is likely to be. This is often where early architectural advice is most valuable – helping you understand what you can, can’t, and shouldn’t change before decisions are locked in.

Common early mistakes

One of the most common mistakes I see is designing before understanding the real constraints – or the likely costs. This often leads people down paths that were never viable, wasting time and energy early on.

Another is underestimating the approval process. Council approvals can take months, and when this isn’t factored into timelines, frustration quickly follows. Designs that don’t respond appropriately to planning or heritage controls often need repeated revision, prolonging the process unnecessarily.

Staging a renovation is another area where assumptions can cause problems. While staging can work, it only makes sense when the scope is genuinely separable – for example, front and rear, or upstairs and downstairs. Temporary layouts or duplicated work often end up costing more in the long run. Early advice can help determine whether staging is realistic, or whether it simply delays the inevitable.

Finally, there’s the influence of Pinterest boards and television shows. Inspiration is important, but it needs grounding. Without an understanding of constraints, approvals, and budget, dream outcomes can quickly become sources of disappointment.

So, how do you start?

In my experience, the most successful projects begin with clarity – not drawings.

Some people start by researching independently. Others seek professional advice early on. Many find it helpful to have a focused, feasibility-style conversation to clarify what’s realistically achievable before committing to a design direction – particularly one that council may not support, exceeds budget, or doesn’t align with how they actually live.

My advice is simple: clarity beats speed.

Understanding where you’re heading, what’s possible, and how best to get there allows you to move forward with confidence. Taking the time to unpack your needs – and seeking informed guidance early – almost always leads to better, calmer, and more successful outcomes.
