The building was suffering from movement

Croft’s expertise in residential refurbishment and basements within the Borough of Camden, provided invaluable on the restoration and remodelling of this substantial 4-storey residence, in Primrose Hill. The structural survey and ground investigations enabled us to provide the best structural design for the renovation and basement works.


The new basement was the perfect solution to prevent the building moving further. Croft had to consider a number of complex issues including how to stabilise the road and prevent it from collapsing into the basement excavations. A line of secant piles were drilled into the ground along the road side, once installed the soil could be safely excavated and the new basement constructed.


Party Wall lines. Secant piling cannot be placed under the building along the party wall lines. Instead, we designed sequential underpinned retaining walls.
