The concept is related to the preservation of historic buildings and the integration of new, modern elements. One approach to this type of design is to add a raised volume, or "cloud," of office space to the building, while preserving the original scale and character of the historic structure. This can provide relief from additions that might otherwise overwhelm the original design, and allow for the integration of modern amenities without compromising the integrity of the historic building.
It is important to carefully consider the design of any additions to a historic building, in order to ensure that they respect the original architecture and do not detract from its historical significance.
