Here is wonderful floor plan rendering by Kristen Hansen. She is a freelance architectural illustrator who specializes in line drawings and hand renderings. Check out her website, Krishansendesign.com . Here is a quote from Kristen about the importance of hand rendering, “In the midst of cold digital representations of the built environment, there is an alternative, friendlier way to present to clients. Hand drawing and rendering captures the warmth and character of a building’s exterior and interior. And sometimes, artwork by hand can offer a faster turn around time than tedious computerized 2D and 3D modeling.”
Here are two more images from Kristen’s web site. The interior marker rendering above successfully shows realistic patterns. This a great visual for my marker rendering students to view. She also is successful at using a variety of values and patterns in her line drawings. I am interested to see how in the exterior residence found below, she adds darker values to emphasis the negative areas in between the rocks.
