Upcycling is not a new phenomenon.
Here are examples of it's very best from a 2021 conversion of a Victorian wardrobe
To an Edwardian conversion of early 19thC square piano into a dressing table..
Upcycling is all about doing it for the enjoyment, the environment and pleasure to re-invent use.
The conversion will increase the value for insurance if you factor in the cost of your time and materials.
Maybe one day the market value will increase too?
