How do Interior Designers charge their fee?
This depends on the designer and how much work there is to do! Some charge a project fee, some charge by the hour. I do both, depending on what the work consists of. Sourcing items (of furniture perhaps) is charged by the hour. This is because it always varies on how long it can take and when the client gets round to making a decision! Building an extension or converting a loft space is project based because I know how much will be involved, the elements needed and how long things will take to order and install. In this instance, a set fee is charged. Extras can be added on to project work and frequently are of course, but if you do your planning beforehand most items can be costed at the initial stage.
