According to her friends, the supermodel wants to leave her London home as she feels a new house can make it easy for her to move on from her split.
"Kate always felt the house was a little dark with its wood-panelled rooms and small windows but grew attached to it," a friend said.
The luxury property which Kate, 41, bought in 2011 was once home to Romantic poet Samuel Taylor Coleridge.
The ramp star may shift back to Primrose Hill, alongside close friends Jude Law, Ewan McGregor and Sadie Frost.
