A fire-ravaged £4.5million Georgian mansion on Millionaires' Row was being transformed into a dream family home, neighbours have revealed.

Grade II-listed Hollybush House, in Barnet, was destroyed after a fire tore through the nine-bed home in a matter of minutes in the early hours of Monday morning.

Planning documents submitted to Barnet council show it was currently undergoing extensive renovations to restore the building.

Neighbours today said the owners had ploughed in thousands of pounds to carry out the works, which included repairing the roof and laying stone flooring in the hallway.

They also wanted to reopen a historic fireplace in the first floor master bedroom.
