When planning a home extension in Sydney, it’s easy to assume that more space means a much bigger price tag. But here’s something many homeowners don’t realise: the cost difference between a 60m² and a 70m² extension is often quite minimal. That’s because the major expenses—like planning approvals, scaffolding, and insurance—are already covered. The extra cost? It’s mostly just materials. This is not where you save.
At Rossmark Building Designers, we’re a multidisciplinary team of designers and builders who work closely with you to make the most of your renovation budget. Whether you’re extending your home to accommodate a growing family or to add long-term value, we’re here to guide you every step of the way. Here are some tips we use for our clients.
Think Long-Term, Not Just Budget
While it’s tempting to cut costs, a short-term saving might not serve you well in the long run. Most families can’t afford multiple home renovations, so it’s worth investing in smart design and quality materials now. We can help you make decisions that stretch your budget that adds lasting value that can evolve with your family’s needs.
Boosting Value Without Breaking the Bank
Not sure where to invest? We’ll guide you on whether a bathroom addition, a laundry upgrade, or a kitchen renovation will give you the best return. Every house has its quirks, every home has different needs, and we tailor our advice to your family’s lifestyle and goals—especially if you’re planning a home renovation in Sydney.
Design Smarter, Not Just Bigger
When it comes to home renovations, it’s not just about adding space—it’s about using it wisely. We often recommend a layout with two bedrooms, one bathroom, and a living space over squeezing in three bedrooms. That extra living area or well-placed bedroom can evolve with your family’s needs—whether it becomes a teen retreat, a study zone, or even a kitchenette in the future.
Why We Recommend a Second Living Space (If You Don’t Already Have One)
If your home doesn’t currently have a second living area, this is the perfect time to consider one. As kids grow into teenagers and young adults, they naturally crave more independence. A dedicated living space gives them room to relax, study, or hang out with friends—without needing to leave the family home.
This kind of space supports their development while keeping them connected to the household. It offers privacy and comfort, while still being under one roof. It helps create a “go-to” home, not a “go-from” home—a place where your kids feel welcome, respected, and at ease.
Already Have Two Living Spaces? Focus on Bedroom Design
If your home already includes two living areas, the focus may shift to adding more bedrooms. But even then, thoughtful design is key. We recommend ensuring that the new bedrooms are connected to a shared space—like a nearby lounge or retreat—so they form a cohesive “young adult zone.”
This layout gives older children or young adults a sense of independence and ownership within the home, while still being part of the family environment. It’s about creating a balance between privacy and connection—something that’s essential for their growth and your peace of mind.
Don’t Forget the Wet Areas: Supporting a Growing Family
When planning additional bedrooms—especially for teenagers or young adults—it’s not just about where they sleep. It’s also about how they live. That’s why we always recommend considering a second wet area, such as an ensuite or an extra bathroom, as part of your home extension.
As your family grows, so does the demand for privacy and convenience. A second bathroom helps reduce morning bottlenecks, supports personal routines, and gives older children a sense of independence. It also adds significant value to your home—something that’s especially important if you’re planning a home extension in Sydney, where space and functionality are key selling points.
Pairing new bedrooms with a nearby bathroom or ensuite creates a self-contained zone that feels like a private retreat, while still being part of the family home. It’s a thoughtful design choice that makes everyday life smoother and more enjoyable for everyone.
