His method was defined by a meticulous eye for structural detail. As a writer and museum official, he viewed paintings and buildings as documents of history. His sketches and watercolours avoid unnecessary flourish. They provide a clear record of architectural forms. This precision was a reaction to the romanticised views of the past. Van Riemsdijk preferred to document the physical reality of a site. He used clean lines to capture the essence of Dutch ecclesiastical architecture.

Collectors value these works for their clarity. The drawings function as both art and archive. They suit contemporary interiors that favour minimal decoration. Because Van Riemsdijk understood the mechanics of museum display, his compositions are balanced. These prints offer a connection to the Dutch Golden Age. He spent his life protecting the objects of that era. His work represents a bridge between nineteenth-century scholarship and the modern appreciation for form.
