Manor House - Cologny 1223


EDDIFIS was commissioned as a general contractor for the major refurbishment of a multilevel villa with several outbuildings dating from 1952 on a 2,700 m2 (29,000 sq. ft.) landscaped plot.

The property was bought by a couple who wanted to see their children grow up in a wealthy residence with a lot of space that opened up onto the gardens overlooking the lake. We designed spaces that combine creativity, functionality and technicality. This complex project with a high surface area required a detailed feasibility study. Precise costing, a rigorous methodology and daily site monitoring were key to ensuring that the project was successfully completed and that the owner was fully satisfied. The quality of the work provided, respected deadlines and respected costs were the 3 commitments in our contract, and we honoured them all.
