Estimates of the cost in February 1

Estimates of the cost in February 1929 were approximately half a million Francs, although this excluded the cost of the lodge and the landscaping elements (almost twice the original budget). The project was tendered in February with contracts awarded in March 1929. Changes made to the design whilst the project was being built including an amendment to the storey height and the exclusion and then re-introduction of the chauffeur's accommodation led to the costs rising to approximately 800,000 Francs. At the time the project started on site no design work had been done on the lodge and the final design was only presented to the client in June 1929. The design was for a double lodge but this was reduced to a single lodge as the costs were too high.[12] Although construction of the whole house was complete within a year it was not habitable until 1931.[13]
