Renovating vs Rebuilding: Making the Right Investment in 2025

Renovating vs Rebuilding: Creating a Custom, Future-Proof Property

Rebuilding means demolishing the existing structure and constructing a new, optimised building from scratch. Facing the renovating vs rebuilding dilemma? This critical decision impacts your budget, timeline, and property value. With Australia’s construction costs fluctuating and sustainability standards tightening, making an informed choice has never been more important.

Key Benefits of Renovating and Rebuilding

✔ Total Design Freedom – Tailor every element to modern lifestyles
✔ Superior Energy Efficiency – Meet 7-star NatHERS ratings with new materials
✔ Optimal Layouts – Open-plan spaces, smart home integration, and accessibility
✔ Higher Resale Value – New builds often command 10-15% premiums (Source: REIA)

When to Choose Renovating and Rebuilding

  • The structure is unsafe or severely outdated

  • Renovation costs would exceed 70% of rebuild expenses

  • You need radically different spaces (e.g., adding floors)

  • Maximising sustainability is a priority

Simcore’s Sustainable Upgrade at Broadway on Ann, Brisbane

 

Current Project

At Simcore, we believe the future isn’t only built from the ground up — it’s also built on the smart transformation of what already stands.
 
Our current project at Broadway on Ann, a landmark 15-storey residential complex in the heart of Brisbane’s Fortitude Valley, exemplifies this philosophy.
Through a specialised retrofitting and maintenance strategy, we’re elevating the performance, resilience, and sustainability of an established structure using one of the most advanced waterproofing solutions available today: the GAF EverGuard® Extreme TPO System.

  • 247 one- and two-bedroom apartments.
  • Basement parking facilities for residents.
  • 600 sqm of ground-floor retail accommodation.
  • A rooftop terrace with BBQ area, feature glass gable pool, and gym.
  • Secure storage areas on each floor for bicycles and personal items.
