1st floor additions
Maximise your home’s potential with a custom-designed 1st floor addition by Wal Robbins. Whether you’re after extra bedrooms, a parents’ retreat, a dedicated workspace or a full second living area, we create functional, stylish spaces that complement your existing home.
1st floor additions are ideal for growing families who love where they live but need more room to move. Adding upward, rather than outward, helps preserve valuable outdoor space while significantly increasing your home’s floorplan and resale value. From concept to completion, our team works closely with you to ensure the new level integrates seamlessly with your ground floor layout and overall aesthetic.
Our experienced builders and designers understand the structural and planning requirements specific to 1st floor additions in Sydney. We manage council approvals, engineering reports and project timelines, so your build stays on track and on budget. At every stage, quality craftsmanship and attention to detail are our priority.
Whether you’re building over an existing single-storey home or extending an upper level on a sloping block, Wal Robbins brings decades of experience to your project. We’ve helped homeowners across Sydney reimagine their space without the stress of moving or sacrificing location.
