Built between 1914 and 1916 for the Kroller Muller family, Dutch shipping magnates and patrons of the arts, Holland House has been highlighted by many as one of Berlage's leading works.
Kees van der Sande, director of London-based KCA, said: 'This is a once in a lifetime project to work on such an important building and put right some of the less sensitive alterations of the last 90 years.'
Described by Nikolaus Pevsner as a 'remarkable design, very idiosyncratic and very alien to the London of its date', Holland House was seen to be one of London's architectural curiosities because of its early modern approach.
Viewed as the 'father' of modern Dutch architecture, Berlage also designed The Hague's municipal museum, and was often noted as being a major influence on the work of Mies van der Rohe, and movements such as De Stijl.
It is unclear when the work will be completed on the building but it is likely to start early in the New Year.
