Selling garden

Thanks! Getting Planning Permission seems scary but I have a daughter who should be able to help.

One of the main planning concerns would be access. There are stringent rules set by the Highways department on vehicle access to housing, usually to do with sight lines on exiting the plot. It would depend on what sort of road the plot is on.
As has already been stated, an informal chat with your local planning office would be the best start. Hope it goes well.

You can talk to your local planning departmennt, they do not charge for an enquiry. If there is similar building already in your area you will stand a better chance. In addition you can ask an Estate Agent to come round to look and advise what you could expect to market the plot for and if there is a demand locally for building plots.
