Final answer:
The Barcelona Pavilion, designed by Ludwig Mies van der Rohe, is a prime example of a building that best embodies the architectural principle of "less is more".
Step-by-step explanation:
The Barcelona Pavilion, designed by Ludwig Mies van der Rohe, best embodies the architectural principle of "less is more". The pavilion is a minimalist structure with clean lines, simple materials, and an open floor plan that creates a sense of simplicity and elegance. Its use of space and pared down architectural elements exemplify the idea of reducing a building to its essential qualities.
The building that best embodies the architectural principle "less is more" is the Barcelona Pavilion designed by Ludwig Mies van der Rohe. This principle is about achieving simplicity in design by arranging the essential components of a building to create an impression of extreme simplicity. In the Barcelona Pavilion, space is used minimally and architectural elements are pared down, which is indicative of Mies van der Rohe's commitment to this design ethos.
