Create an architectural render that looks like a hand-drawn sketch, emphasizing rough lines and gestural strokes. The building design should incorporate elements of modern architecture, with a focus on geometric shapes and open spaces. Use a monochromatic color scheme or soft pastels to mimic the appearance of graphite or colored pencil. Include annotations, dimensions, and design notes to enhance the sketch-like quality, capturing the essence of a conceptual architectural drawing. The render should convey a sense of creativity and spontaneity, with an emphasis on form and space rather than precise details
