Retrofit Advisory

A practical roadmap to help homeowners improve comfort, health and energy efficiency in existing homes.

Architect-led retrofit advisory process tailored to your home, goals and budget.

Why retrofit

Comfort is rarely achieved through a single upgrade.

It comes from a series of considered improvements that work together over time. The goal is not simply to renovate more, but to make better decisions in the right order — helping homeowners prioritise improvements, maximise the benefit of future upgrades and avoid unnecessary rework.

You may already be asking…

Many existing homes are uncomfortable, expensive to run, or no longer supporting the way people want to live.

“We’ve improved parts of the house, so why is it still uncomfortable?”

“Should we prioritise insulation, glazing or heating?”

“Is double glazing actually worth it?”

“What improvements will make the biggest difference?”

“What can be staged over time?”

“How do we avoid spending money in the wrong order?”

Who is retrofit advisory for

Retrofit is ideal for you if:
Own an existing home and want to improve comfort, health or energy efficiency
Unsure where to begin or which upgrades should be prioritised
Want to avoid spending money on low-impact improvements
Are planning future renovations and want a clearer understanding of retrofit opportunities
Prefer a staged approach that aligns with your budget and long-term goals
Want greater confidence before investing in upgrades or renovation works

Purpose

What We Focus on Retrofit Advisory

01   Understanding how the home is currently performing

02  Identifying likely causes of discomfort and heat loss

03  Prioritising upgrades likely to deliver the greatest impact

04  Exploring staged improvements over time

05  Sequencing upgrades to support practical implementation and future works

06  Helping homeowners avoid spending money in the wrong order

How it Works

Existing home review

  • Orientation and passive solar opportunities
  • Glazing and shading
  • Likely insulation performance
  • Draught and ventilation issues
  • Heating, cooling, hot water and ventilation systems
  • Areas contributing to discomfort and heat loss
  • Room layout and functionality
  • Accessibility and future adaptability

NatHERS thermal modelling

Prepared by an external consultant and coordinated by Fluit Studio — providing a clearer understanding of how the home is currently performing and where improvements may have the greatest benefit.

Additional testing (optional)

  • Blower door testing
  • Thermal imaging
  • Hygrothermal testing or modelling (WUFI)
  • Certification services
 

Fluit Studio coordinates and interprets this information to support retrofit strategy and decision-making.
