The best architecture comes from a synthesis of all the elements
That separately comprise a building,
From its relationship to the streetscape
Or skyline to the structure that holds it up;
The services that allow it to work;
The ecology of the building;
The material used;
The character in the spaces;
The aesthetic dimension and the beauty of light and shade;
The symbolism of the form;
And the way in which it signals its presence in the city or the countryside.
I think that holds true whether you are creating a landmark or deferring to a historical setting.
by Norman Foster
