Neighbours in Primrose Hill are urging people to oppose plans for a new “mega basement”, at the former home of Hollywood stars Aaron and Sam Taylor-Johnson.

There are concerns there could be years of building work misery and that the plans for the basement go against Camden’s new Local Plan.

The new owner of number 6 Albert Terrace hopes to excavate a basement to build a gym and swimming pool.

According to the Land Registry, the new owner is Mark Golinsky and the price of the house was £11.5m in 2016.

Campaigners claim that this would be a basement underneath a basement.

The Local Plan, adopted by Camden council on July 3, states that basements must not be built under existing basements.

Developers Iceni Project, however, argue in their planning application that there is only a lower ground level to the five storey Italianate family home, rather than an existing basement.

Primrose Hill campaigner Phil Cowan has been sending letters to his neighbours to warn them of the “mega basement.”

He wrote: “If this application is granted it will cause unprecedented noise and disruption for up to two years as well as potential permanent damage to surrounding land and values of neighbouring properties.”

Mr Cowan is also concerned that the development is at the apex of two busy roads, Albert Terrace and Regent’s Park Road, which includes a bus route – which could lead to “traffic chaos and increased pollution.”

The Iceni developers say that the basement will only be one storey high, in keeping with Camden’s local plan, with a swimming pool which will have a depth of 1.5m to 3 metres.

Residents remain unconvinced that this is not an application for a second basement at the property.

John Cottrell commented on the application: “The Oxford English Dictionary (OED) defines basement as ‘the floor of a building which is partly or entirely below ground level.’

“By this definition, the existing lowest level of the building is clearly a basement.”
