First Floor Additions Built on Solid Engineering
Adding a second storey doubles your living space without touching your land footprint. It's one of the smartest ways to grow a home on a smaller block. Exalt Builder Pty Ltd brings something most builders can't: Audifax Benitez is a licensed builder and a qualified civil engineer with over 30 years of experience. When you're adding load to an existing structure, that engineering knowledge isn't a bonus. It's essential.

Why Exalt Builder for Your Second Storey Addition
Civil Engineering Background for Structural Confidence: A second storey addition puts significant new load on your existing home. Audifax assesses the current foundations and framing, determines what reinforcement is needed, and designs the addition so the structure performs properly. This is where his engineering qualifications make a real difference.
Minimising Disruption While You Live Below: Many families choose to stay in their home during a first floor addition. We plan the build sequence carefully, staging work to keep ground floor living areas functional and safe. Temporary weatherproofing protects your home from the elements while the roof is open.
Seamless Design From Ground to Sky: The worst second storey additions look like a box dropped on top of a house. We design additions that integrate with your existing roofline, facade, and proportions. Our building team ensures the finished home looks like it was always two storeys.

Benefits of a First Floor Addition
More Home Without Losing Your Yard: On tighter blocks across Sydney, building out isn't always an option. Going up preserves your outdoor space, your driveway, and your garden while still giving you the extra bedrooms, bathrooms, or living areas you need.
Significantly Increase Your Property Value: A second storey can substantially lift your home's value. Buyers pay a premium for two-storey homes across Sydney, particularly when the addition is well designed and properly built.
Stay in the Suburb You Already Love: Upsizing usually means moving further from the city. A first floor addition gives you the space of a bigger home without changing your commute, your kids' schools, or your local community.
