This falls under the category of designs in "harmony" with their surroundings. The architecture firm is called Waterstudio and this project is located in the Netherlands. There are a plethora of Polders in the Netherlands that are used as areas for flood waters to settle during heavy rain storms to protect neighboring homes from being damaged.
The project uses the water that fills up the Polder to cool the apartments. To help you better understand the design technique I will ask that you take a moment and try to find some repetition of the building forms on the picture to the right.
Can you see a pattern beginning to form? This is a type of design that uses a standard component, in this case the apartment unit, to help simplify the form. Then the Architect provides a couple parameters; Greenhouses, patios, building materials, quantity of units per acre, etc.; to begin establishing a method for organizing elements along the site. From here a variety of studies can be conducted to establish size of units, geometries between units, allow more sun, create privacy or just present "cool" and visually appealing architecture that the Architect can then evaluate and digest to re-present to a client.
As you can see there are a variety of ways that Architects can help form a thesis to develop the architecture that you see, and if you have read my other blogs you are starting to learn about a few of them.
