In an answer to a Conservative Parliamentary Question, Baroness Andrews, the Lords Minister for Local Government, said that that a tree house would be taken into account during the banding of a property for council tax if it "adds value".
She said: " In the case of a new dwelling, all features of the property that affect value are taken into account in the banding. The test is whether, in the open market, the presence of a tree house would have any material effect on the property's capital value:
in general this is unlikely.
"In the case of an existing dwelling, if the tree house was a later addition that added value, it would only be taken into account when the dwelling was subsequently sold."
I don't think theres many people who have to worry about paying extra council tax for a treehouse. It's just political sniping, conservatives trying to score points."No-one is safe from Brown's tax bombshell  not even children."
Sensationalism, hysterical even, unless you've erected a treehouse like the one below...
