Iberica has been given the go ahead to transform a former auction house, Hepper House in Leeds city centre into a new tapas restaurant for the chain.
The Grade-II building has been leased to Iberica and covers 5,700 sq ft of space.
Iberica's plans to bring a building of 'high architectural merit' back into use is cited as one of the main reasons behind the planning permission being granted.
The group currently operates five restaurants in London and one in Manchester.
