I had a freezing cold conservatory for 10 years and wasted £3k trying to make it warmer — this is how I've finally solved the issue

From the moment I bought my 1970s home a decade ago, I knew I wanted to change the conservatory.

It was a sizeable 4x3m space off the kitchen-diner but, as I discovered in my first year of living there, the glass roof meant it was utterly freezing in winter and roasting hot in summer — neither of which were conducive to being able to use the room year round. Over the years, I spent more than £3,000 trying to make the space usable, but nothing really worked as I wanted it to.
