His work focuses on the scale and volume of Neoclassical structures. In pieces like 'A View of the Vestibule of Saint Mary at Rome', Blondel uses deep shadows and sharp contrasts to define stone surfaces. He avoids the cluttered detail found in traditional topographical views. Instead, he emphasises the geometry of vaults and columns. His training in architecture allowed him to maintain technical accuracy while creating a sense of immense space. He often placed small figures within these vast interiors to provide a sense of human proportion against the heavy masonry.

Modern collectors value Blondel for his clean lines and monochromatic palette. These prints suit contemporary interiors because they offer a sense of order and architectural depth. The lack of excessive ornamentation makes his work feel relevant to today's aesthetic. His focus on light and form ensures these pieces are windows into a quiet, structured world. They provide a sophisticated atmosphere for a study or a hallway without overwhelming the surrounding decor.
