When does a conservatory become an extension and why is it important to understand this?

When looking into conservatory ideas many homeowners often plan on using their new glass structure as a way of adding useful extra space to their homes, as well as somewhere to sit and enjoy their garden. This can lead to questions being asked about whether it might be better to add an extension rather than a conservatory – and in fact there can sometimes be a little confusion around what the difference between the two is.
