Selling part of my garden!

[mumtoafrog]

Good evening,

My neighbours have approached me about buying the bottom of my garden, the size is around 15m by 10m and includes a large shed, a small shed with dog kennel, and a chicken coop.

How do you find out the value for something like this? Can anyone point me on the right direction? Or give me a rough idea on how much gardens land can sell for?

Any help would be much appreciated.

As a point of reference, my parents paid the council £300 for a similar sized plot of land adjacent to our garden in around yr 2000. Inflation adjusted that is just over £500 today.
