In the layout stage, it's time to decide if the design concept fits the space. That involves looking at the size and shape of the room, the ceiling height, the amount and type of natural and artificial lighting, and any environmental concerns. Now is the time to identify any potential obstacles, and address any questions you might have. Have you thought through issues like traffic and activity levels, or requirements such as moisture resistance or noise reduction? Does the planned project transition well into the rest of the home? Careful analysis during layout can save costly headaches down the road.
