A millionaire property developer’s fresh plans for a “glass and steel” extension on top of homes in Hampstead have been met with fierce opposition from neighbours in the historic street.

Andrew Tripp’s proposals for a private glass lift to a “crash pad” for his five children were turned down by Camden Council in 2011.

But Mr Tripp, whose family has owned the freehold of the property since the 1960s when it was a nursing home, has renewed his bid to transform his fifth-floor flat into a three-bedroom penthouse by scrapping the private elevator from new designs.

He has submitted a fresh application to Camden Council planning officials for the extension to Mourne House in Maresfield Gardens – the street where The Freud Museum and the former home of Prime Minister HH Asquith are also based.

Dr Carol Cooper, who writes for The Sun newspaper and lives beneath the flat, said: “The previous plans were pretty outrageous and had everyone up in arms.

“But these proposals still leave us with a glass and steel storey on top of our homes in the middle of red brick Fitzjohns and Netherhall Conservation Area.”

The council has already received 15 letters of objection to the plans.

The town hall is consulting on the plans until next Thursday (January 17).
