Holland Villas is a six-storey detached villa in Kensington. Croft worked with Intelitrade Developments on the design of the new basement and complete refurbishment of the upper floors.

The main challenges we encountered were below ground with a full footprint basement extending in to the rear garden (an impressive 33m long x 16m wide x 4 metres deep).  The removal of a large section of the flank and rear walls required the design of suitable stability frames.

Due to the significant amount of internal remodelling, a metal deck floor was designed internally on the ground floor and in-situ concrete floors externally. The metal deck floor and the concrete slabs not only provide robust floors but also provide propping to the retaining walls. The top prop retaining walls are economical as these reduce the thickness of concrete and the amount of reinforcement.

Croft monitored the building continuously during the basement construction.   We reviewed the monitoring reports sent by the monitoring company and gave advice to ensure that the basement construction did not affect the neighbouring buildings and the property.  Croft were involved in supervision of the works by contractors to ensure that the works were carried out according to the design.
