What is in the design that you consider to be good design? What are the criteria?
I would consider the followings as a criteria for a good design:
Aesthetic Design- the building should be successful and visually attractive, whatever its style or type is, in other words, it refers to the visual and sensory appeal of the building. Beauty is the ultimate test of good architecture. Without beauty, a highly functional building is merely utilitarian. Aesthetic design would affect the visual qualities of the building.
Functional Design- this refers to how a building is being used. It must accommodate practical requirements for every purpose within its walls. A building without function may be beautiful, but it's sculpture, not architecture. Functional design affects the value given to the building.
Craftsmanship And Materials- the building should have high standards in the choice and handling of materials, meaning how the building stands up. To be an architecture, it must create beauty from structural necessity. Craftsmanship and materials of the building would affect the quality it.
The building above is an example of an aesthetic and functional building. The building looks visually appealing and at the same time it is also functional.
The picture above is an example of a good craftsmanship and material building.
