Due to the expense and difficulty of moving home, more and more people are opting to extend their living space and stay put.

A loft conversion is a great way of doing this but there are a few challenges to consider before instructing builders to get started. While your loft conversion may not always require full planning permission, there are still regulatory requirements to comply with to ensure it is habitable.
