Once you have decided to add a conservatory to your home, one of the first things to consider is whether the size & scope of the conservatory will require planning permission. In most cases the average size residential conservatory would be considered to be a "permitted development" and as such the conservatory would not automatically require a planning application to be made. Whilst the large majority of new conservatories are normally exempt from planning permission or building regulations, there are some rules that need to be taken into account , time spent in advance looking into any potential issues will be time well spent. You should first check if any of these rules apply to your proposed conservatory.
