If your family is outgrowing your home, you’re probably weighing your options: add a second storey or knock it down and start fresh?
It’s a big decision and, while both have their place, when you add budget and emotional attachment to the mix, the decision becomes a no-brainer.
In Most Cases, Adding a Second Storey is the Best Way to Get More Room With Less Stress
The only time we’d recommend a knockdown rebuild is when your home doesn’t have solid foundations — because building up only works when your base is strong.
However, if you love your home, the street is quiet, the neighbours are great, and the kids are settled in school, a second-storey addition is going to cost you less and disrupt your life less.
The Last Thing You Want to Do is Move into a Rental or Live Through the Chaos of a Full Demolition
By building up, you can take advantage of the structure that’s already there and add space without giving up the home you already love. You keep the familiar layout, the backyard where the kids play, and all those little details that make your house feel like home.
A second-storey addition is also more budget-friendly than a complete knockdown rebuild because it uses the structure you already have. This saves you from starting from scratch (and from footing the bill for it).
Beware of Hidden Demolition Costs
For instance, I heard of one family in Newcastle who were all set for a knockdown rebuild until demolition uncovered asbestos. That one discovery blew out their budget and timeline by months.
Likewise, one home we looked at had asbestos under metal cladding, which was under brick veneer. All of that had to be removed (layer by layer) before demolition could even begin.
What starts as a straightforward project can quickly turn into a nightmare with unexpected costs and delays.
A second storey addition is more predictable. It gives you the space you need without exposing you to unnecessary risks.
Preserve the Charm and Nostalgia of Your Family Home
Second storey additions also help you keep the emotional heart of your home. You don’t have to say goodbye to the living room where your toddler took their first steps or the kitchen where you’ve hosted countless family dinners.
By building up, you’re creating new memories right where the old ones live. It’s the best of both worlds.
Plus, because it’s faster and more cost-effective, you can avoid the stress of a second mortgage.
Of course, choosing between a second storey or a knockdown rebuild is only part of the equation — a smooth, stress-free build also comes down to having the right information from the start, and working with a builder who knows what they’re doing.
