Second storey additions in Brisbane & the Gold Coast
We transform single-storey homes into spacious two-storey family homes without the need to move. A second storey addition is one of the most impactful investments available in SEQ’s high-value suburbs where land is at a premium.
The case for going up
In Brisbane’s inner and middle-ring suburbs and across the Gold Coast, blocks are finite and expensive. The most cost-effective way to significantly increase your living space is often to build up rather than out. A second storey addition can double your home’s floor area while preserving your garden and outdoor space — and typically delivers a strong return on investment in high-demand SEQ property markets.
Common upper floor configurations include master bedroom suites with ensuite and walk-in wardrobe, additional bedrooms, a home office, a media room, or a combination of these — often with elevated views across Brisbane or the coastal Gold Coast.
Structure, design, approvals & build
Structural Assessment
A structural engineer assesses the existing foundations, walls and roof to determine what strengthening is required.
Design
Our designers develop the upper floor layout, integrating stair placement, rooflines, privacy and natural light.
Council Approval
DA approval where height limits, setbacks or character provisions apply — we manage all approval processes.
Construction
A sequence that minimises disruption to the lower level, with extensive weatherproofing during the build.
