I have been trawling the internet and this site trying to get a difinitive answer to this question. I have just started building on a site that was given to me by my Dad. I know I don't have to pay Stamp Duty on the site but is there any Stamp Duty liability on the completed house? I am not a FTB, the house is 230Sqm and the valuation for the completed house was €635,000. Thanks!
