BELSIZE Park A-listers Gwyneth Paltrow and hubby Chris Martin are following in the footsteps of fellow Camden developers Alastair Campbell and Jamie Oliver by spreading out into the house next door.

The couple have snapped up the property adjoining their home and are building a two-storey extension in a bid to create a 33-room mansion.

Builders have begun work transforming the house and plans show they intend to knock through the connecting walls to create eight rooms on the lower ground floor, six on the upper ground, five on the first floor and eight on the second floor.

In the extension they plan to put a gym, changing room, three bedrooms and a bathroom.
