In terms of outbuilding design again the possibilities are almost endless, owing to their nature of being detached from the host property there is usually a lot of flexibility when it comes to their external look, as with extensions there are permitted development rights in place that will allow you to potentially design and construct an outbuilding without formal planning permission.If you’re thinking about an outbuilding project or you’re unsure about how to go about your outbuilding design, take a read of the below to get you started on your journey.
