Question to the HM Treasury:

To ask His Majesty's Government whether a treehouse within the curtilage of a domestic dwelling is deemed to be a material consideration by the Valuation Office Agency when a property is valued for council tax in Wales.

The Valuation Office Agency considers each property valuation on a case-by-case basis, considering the impact that any features could have on the property’s value and whether any such features would be classified as a self-contained unit.
