As this would be an extension, it would still need to be permissible and accepted by any applicable building regulations (IE – the size, how close to boundaries, etc).
In particular, the footings will need to be checked – for a single storey extension they will need to be at least 1 metre deep and 60cm wide. If not, then you would need to demolish the conservatory to have the footings set correctly for the extension anyway, I’m afraid.
This can be checked by digging some trial holes around the perimeter of your conservatory to check, I would recommend checking with 3 holes in different places along of the perimeter.
If the footings did meet these required building regulations, then you could potentially convert the conservatory, however, this would still require correct planning from an architect, receive planning permission (depending on size) and meet all other building regulations.
It would still require removing the conservatory fixtures to building from the walls. Potentially the corners could be underpinned and have catnics along the wall areas – but the feasibility of these options may depend on your specific circumstances, so it is best discussed with your architect or structural engineer.
Overall, it is most likely that you will need to demolish the conservatory in the process, as the footings/foundations are unlikely to be sufficient.
I hope this helps! "
