Creating a sustainable home in North Oxford
Nilam transformed her 1960s Paddox estate house with a heat pump, insulation, and ventilation – cutting carbon and improving comfort.
For Nilam, retrofit was about living in line with her values. Inspired by her love of nature and concern for future generations, she wanted her 1960s Paddox estate home to be warmer, more efficient, and an example for her neighbours of what sustainable refurbishment can achieve.
About the home
Nilam’s home is part of the Paddox estate in North Oxford, designed by radical post-war architect Eric Lyons CBE in the mid-1960s. She was determined to show how these houses could be upgraded for the future, creating a blueprint that other homeowners in the estate might follow.

Motivations
Protecting the environment
With her boiler nearing the end of its life and an external wall showing cracks, Nilam took the opportunity to tackle these issues and improve her home. Her motivation was clear: to reduce her carbon footprint and live more sustainably.
Helping future generations
Nilam wanted her retrofit to demonstrate the positive role homeowners can play in cutting carbon emissions. She also wanted to create a comfortable, healthy home to enjoy now and in the years ahead.
“I couldn’t have asked for more excellent people. So much integrity, and very principled, very thorough professionals. It was really reassuring. Through all the difficulties, Geordie remained so patient.”

Project guidance
Working with Cosy Homes Oxfordshire gave Nilam confidence that she was making the right choices. Retrofit Coordinators Geordie and Natasha supported her throughout the process, guiding her through challenges and decisions with patience and professionalism.
Even during the COVID lockdown, when material shortages made projects difficult across the country, Nilam felt supported and reassured.

What measures were installed?
Nilam’s retrofit combined heating, insulation, and ventilation upgrades to make the house more efficient and resilient.
Retrofit measures included:
- Air source heat pump
- Replacement of the front door and entrance update
- Cavity wall insulation
- Loft insulation
- Ventilation improvements




The results
Nilam’s home is now warmer, healthier, and free from cold spots. The air source heat pump provides reliable, low-carbon heating, while new insulation and ventilation keep warmth in and maintain good airflow.
Her retrofit journey has not only improved her own comfort and wellbeing but also shown her neighbours what’s possible. She hopes her home will serve as a model for the wider Paddox estate.
Nilam’s story is a reminder that individual choices can create ripple effects – inspiring others and helping to build a greener future.
