Architectural details are an essential part of every flooring installation. Special consideration should be given to floor-to-floor and floor-to-wall transitions, and how floors run across multiple levels. These elements help spaces to flow, creating harmonious movement around a project, softening connections and hiding delineations. Transitions are most effective when they work seamlessly with your floor.
Of course, you could also choose to install flooring transitions as a design statement, or with a contrasting threshold between rooms with different flooring treatments to create a unique design feature. Alternatively, if you have wood flooring downstairs but carpet upstairs, a curated look would be to continue using wood thresholds in the same finish as your floor throughout your project.
