The relationship between these two buildings will be punctuated by a landscaping project consisting of a park and a canal.

The first building, the Class A Office, will be implanted in a triangular site surrounded by streets accentuating design, process and construction constraints.

In response, the volume of the office building will be manipulated using the push/pull technique to generate a smooth wave-like sloping façade.

Two corners will be slightly lifted to facilitate access to the office building as the diagram and the rendering show.

The second building, the Five Star Hotel complex, will follow the main principles of the Class A Office building design process.

 |

Yet, while the sloping surface of the Class A Office building will be a smooth green roof, that of the Five Star Hotel will be a terraced green roof. The Hotel surfaces will then be pixellated.

Such as the first building, two of the corners of the Hotel will be lifted allowing for the access to the building.

As mentioned above, the two buildings will be accompanied with a park and canal to enhance the site and offer spectacular views to the users and clients.

 |
| Hangzhou Waves — Class A Office Building and Five Star Hotel © JDS Architects —> While the buildings are back-to-back, materials and façades treatments will be different. The buildings types might be determined by their programm and orientation. Each building building will be identified by materials and envelope treatments: the Class A Office Building will have a standard façade system: a curtain wall creating a regular grid of the skin, while the Five Star Hotel having a perforated façade that will generate a pixel-type of skin. |
Depending on the program, the two buildings will have their own profile and materials. This will lead to a scaleless affect, exploiting not only the program but also the site conditions.
 |
| Hangzhou Waves — The Five Star Hotel Profile © JDS Architects. —> While the principle of lift of corners being the same to the two buildings, the treatment of those of the Five Star Hotel will reinforce the scaleless quality. |
