I don't suppose I should say this but I think that the people who own these properties and let them get onto a derelict state should be taken to it put against the wall and shot. I'm a Carpenter and Joiner by trade and have retrained as a Building surveyor, it's heartbreaking seeing properties that are left to rack and ruin. With a bit of time and effort they could be brought back into use, there's enough homeless people who could be housed in them.
Sorry if I've offended anyone with blowing my top.
I hope that if you are an Owner/Occupier, your Will is written in such clear terms that your properties do not fall into the hands of the Court/Legal Profession as your surviving relatives fight over ownership. Sadly; a quick search through the records of many of the similar habitations recorded on this forum reveals horrendous legal proceedings - and with all the money tied up in the bricks and mortar there are no monies available to rectify the resultant decay that sets in during the years of protracted in-fighting.
It must also be noted that farms and farm buildings are in many cases not ideal to be used to house none agricultural workers. Many are miles from no where, have very difficult access due to the actual farm lands being sold off over the years to surrounding farming companies. As farming mechanised over the years and motor transport became ever more reliable, one did not need to live in the middle of your acreage or have your staff really close at hand to the land. Thus as farms became larger due to amalgamation,old farm dwellings out in the sticks with no utilities or piped water rightly were abandoned. My late father came from farming stock and my nephew and niece still farm the old holdings - my relations were lucky in the location of the two family farms as it meant that most of the redundant buildings could be turned into holiday lets. Not every farmer/landowner has this option.
