Engineering
Better.
Structural engineers specialising in existing buildings. We help owners, architects, builders and project teams understand, adapt, strengthen and transform existing structures — from heritage buildings and adaptive reuse to forensic engineering, investigations, remediation and temporary works.
Preserving, adapting and understanding existing buildings.
Whether you're navigating heritage approvals, investigating cracking or movement, planning an alteration, exploring adaptive reuse opportunities or assessing the potential of an existing asset, understanding the building comes first.
We have a particular passion for heritage preservation, adaptive reuse and helping existing buildings continue their story for future generations. Our heritage structural engineering work is one of our flagship specialist capabilities.
Whether you're looking to preserve, adapt, strengthen, repair, extend or better understand an existing building, we help clients make informed decisions with confidence.
- Heritage & Conservation
- Navigating heritage approvals, constraints and preservation requirements.
- Cracking & Movement
- Understanding the cause of defects before deciding what to do next.
- Alterations & Additions
- Exploring what is possible before committing to design or construction.
- Adaptive Reuse
- Finding new life and new opportunities within existing structures.
- Development Potential
- Understanding the capacity and limitations of existing buildings.
- Investigation & Advice
- Providing evidence, clarity and practical recommendations before intervention.
When the building is uncertain, the next step shouldn’t be.
Cracks. Movement. Water ingress. Changing requirements. Heritage constraints. Incomplete records.
Whether something appears to be going wrong, or an existing building needs to accommodate a new use, uncertainty can make the next decision difficult.
SFE helps owners, owners corporations, project managers, architects and development teams understand what is happening, what matters and what should happen next.
Through careful investigation, experienced structural judgement and practical engineering, we turn uncertainty into a clear path forward.
Understand what is really happening
We begin with the building itself: its history, available records, visible symptoms, structural behaviour and any previous changes. Before forming opinions, we gather evidence.
Separate genuine risk from uncertainty
Not every crack signals failure, and not every hidden condition is harmless. We identify what requires action, what requires further investigation and what can be managed with confidence.
Develop a solution that works in the real world
Whether the outcome is monitoring, repair, strengthening, modification or adaptive reuse, our advice considers access, construction sequence, cost, heritage fabric and how the work can actually be delivered.
Give people confidence to move forward
We explain what we have found, what it means and what should happen next in language people can understand and act upon.
Complex problems. Carefully resolved.
