At the moment there are a lot of restrictions as to what the owner of a listed building can do to their property.
An Englishman's (or a Scotsman…) home is his castle and owners of listed buildings should be just as entitled as any house owner to make modifications to their house.
If the house is primarily used as a dwelling then it should have no more restrictions on it than a 'normal' house.
Why is this idea important?
A person should not have restrictions placed upon them because of the type of house they live in.
Apart from that civil liberties issue these listed buildings regulations also restrict a lot of beneficial work (eg energy reduction/insulation) from going ahead.
