A mansard roofed new flat was to be added to the top of the conversion of this Victorian house. This required the use of a wall that had been previously raised by the adjoining property to enclose the new flat. As Building Owner’s surveyor we established this was a party wall.
Under The Party Wall etc. Act 1996, to make such use of a wall requires payment of defrayed costs, to share its use. This was evaluated using Building Cost Information Service data and negotiated with the Adjoining Owner’s surveyor to reach settlement.
