I am selling my only house and my query is do I have to buy another house with the money or can I do what I like with it. Is the capital gained subject to tax?
True in 99% of cases but not all. If the value of the site reflects a possibility of further development, then CGT may arise. Get professional advice if this is an issue.
Afraid so, and the development issue is a completly seperate issue, the development one is that you only get PPR CGT relief on the acquired value that would have been obtained if the home was sold as a residency.
PPR CGT relief is granted on your home where it and the grounds were occupied by the owner as his/her ppr up to a maximum site of one acre (excluding the actual site that the bricks & mortar sits on).
