James J Fox, 19 St James's Street, SW1A 1ES

What was argued and what the tribunal found

The appellant sought a reduction in the zone A rate from £2,000/m² to £1,500/m² and continuation of a 22.5% material change of circumstances allowance for building works. The tribunal found the existing zone A rate of £2,000/m² was supported by rental evidence on comparable properties opposite the subject property and was reasonable. However, the tribunal allowed a 10% temporary allowance for the material change of circumstances caused by building works at the adjacent property, effective from 1 April 2017 to 16 July 2018, reducing the RV from £125,000 to £113,000.
