Use pencil to draw the position of walls on the floor. If the floor is covered with carpet, outline the wall using a duct tape.
Cut the floor along the lines that you drew in the last step. Where two plates meet, simply pull both of them out. Use floor plates to cover the surface of the closet floor.
Floor plates are wood pieces upon which the doors of the closet will rest. Use nails to attach the floor plates to the floor with the help of a nail gun. There is no need to remove or roll out the carpet, just nail directly over it.
Make the design of stud pattern on top of the floor plates. Start from one corner and lay an X on the surface. Go on placing X along the line after every 6 inches, making sure to place on under the edge.
Make an identical set of floor plates which will be used as the roof of the closet, or you may use the roof of the house as the roof of the closet.
Use a builder’s level to adjust the top floor tiles on top of the closet. If your closet does not touch the roof of the room, you cannot use the level.
Use screws to fix top plates to the ceiling, it is recommended to put screws into joists. Install the wall panels and the two wooden doors, and your closet is good to go. Make as many compartments in the closet as you like by the use of plywood panels.
