Overview

## 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.

What it involves

## 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.
