Our Specialist Service 

Ecofurbishment is our economical remodelling and retrofitting of existing buildings using intelligent structural engineering techniques. 

Our Ecofurbishment service harnesses the power of the circular economy to design out the concept of ‘end of life’ for structures, by ensuring that through sustainable engineering approaches they can be reused or repurposed in a continuous loop.

Our Approach

Our Approach

With over 60 years of involvement in refurbishment and retrofit projects, we have honed our approach to deliver exceptional value to clients and teams. 

Our approach swiftly identifies uncertainties in proposed works, ensuring accurate cost assessment during the feasibility stage. Drawing on our extensive experience and knowledge of construction materials, we provide prompt and confident advice for finding suitable solutions. This mitigates risks associated with budget assessment and pre-planning design development.

Our Ethos

As leading structural engineers with expertise in remodelling structures, we bring a unique perspective to your project, emphasising Ecofurbishment ethos:

  • Quick and precise advice to seize new opportunities.

  • Valuable feasibility-stage guidance for understanding and cost-estimating risks.

  • Strong support for planning applications, leveraging our esteemed track record.

  • Assurance that we always have positive solutions at every stage.

  • A commitment to innovation, regardless of the challenges we encounter.

Our Process


We conduct a meticulous appraisal of the existing structure, reviewing archival data and organising intrusive investigations when necessary.

Analyse: We thoroughly analyse the structure in relation to the proposed remodelling, assessing loading allowances and load paths down to the foundations.


If analysis reveals non-compliance with design codes due to loading or alternative load paths, we strategize load testing on key structural elements to confirm their actual capacity.


If a structural element fails a load test, our experienced team investigates methods to strengthen or alter the load path for that element.


Once a strengthening strategy is determined, we deliver coordinated design solutions in collaboration with architects and service engineers.

At Curtins, we apply our expertise to ensure successful remodelling projects with a focus on efficiency, innovation, and optimal outcomes.
