How I Help
Retrofit involves upgrading existing buildings so they don't perform like tents with radiators bolted on. There is sure more nuance to … what retrofit is.
My Process
Every project is different, and the process adapts as needed. But here is how it typically unfolds:
- Discovery – Free 30 minute Zoom session to assess fit
- Home Visit – Proper look on your house and initial feasibility discussion
- Strategic Assessment – Your house analysis and comprehensive report
- Your Options – Retrofit strategies tailored to your budget and timeline
- Design & Delivery – From concept through to completion and monitoring
