Thank you for your reply. I went onto the link you recommended & their form CG64245 seem to suggest that my circumstances may well fall under the term "curtilage" My house is listed with the buildings I wish to dispose of are situated adjacent either side of the house by just a few feet.
These buildings have been used for garaging and a wood shed to the house. They in fact form a small courtyard just as described in the afore mentioned form.
If I were to sell them separately from the main residence then without a doubt the house would be devalued.
I understand you can not give a definitive answer but do you think it would be worth my time asking for The Valuation Agency to give an opinion on whether a sale would be treated to qualify for relief or am I just reading into the articles what I wish to hear.
That all sounds like excellent advise, and I will do exactly as you suggested.
