The client was motivated to reduce their energy use and to improve their thermal comfort in this beautiful home in west Aberdeen
They were also unsure about how long they might live in the home and hence wanted to know that their investment would have some improvement on their property value
The home was originally built in the 1920s, with two more recent extensions and a room-in-roof conversion. Many of the existing period features were to be retained.
Our Whole House Retrofit service was chosen to evaluate all the options and our Retrofit Coordinators guided them through the project from start to finish.
Local contractors were used for all the measures
