Beyond overall size, a useful drawing includes details such as electrical points, doors, windows and any structural columns near the intended wall, since these all affect how the final panels are configured and joined. Missing one of these details early on is one of the most common causes of delay later in a project. Involving whoever manages the space day to day at this stage can also surface practical details, such as where furniture is likely to sit, that a purely architectural drawing might not capture on its own. Even details that seem minor at the drawing stage, such as the exact position of a light switch, can end up mattering once panels are being fitted precisely against a wall. Reviewing the drawing together with everyone who will use the space, not just those managing the project, often surfaces small but important details early.
