A standard interior door in a typical home is a hollow door, featuring a single piece of wood with one doorknob and a hollow core to prevent the wood from being too heavy to manipulate easily. A Dutch door, on the other hand, have both a top section and a bottom section, each built with a hollow core. These doors have two sets of doorknobs to correspond to the two different parts of the door. Dutch doors are unique in a home and are useful for people who like to be able to regulate the light or space that can be seen through a doorway. If you wish to keep the door entirely open or closed you may, but you can also open up solely the top half of the door or the bottom half if you would like to further adjust the atmosphere in a room. The process of converting a hollow door to a Dutch door is straightforward, but it will require a fair amount of time and effort.

Step 1 -- Measure and Cut the Door

After you've gathered all of the necessary materials and tools to begin the project, measure the height of the door and make a mark halfway down the length of it. If you wish to cut your Dutch door at a different height, you can notate the cut line at this time to your preference. Be sure to mark both sides of the door, and then use your measuring tape and a pencil to draw a straight line across the width of the door to serve as a guide for your cutting.

Step 2 -- Cut and Sand the Door

Cut the door on the line that you've marked using your saw. Once you've cut the door in half, sand down the edges to avoid splinters or any other roughness.

Step 3 -- Cut and Secure your Filler

Using the width and depth of the door as guides, cut a piece of your filler wood to match the length of the cut on either side. The filler must be narrow enough that it will not significantly alter the height of the door. Sand this piece down to smooth it out, and use your wood glue to attach the filler wood to the base of the top portion of the new Dutch door, along the edge of the cut. Attach a second piece of filler to the top of the bottom portion of the new door. This will help to give your door a smooth, professional appearance.

Step 4 -- Add a Doorknob and Hinges

The final step necessary to convert your door is to add a doorknob on the second portion of the door. Follow the doorknob installation instructions, and make sure that the knob is placed level with the other existing one. Next, you'll need to make sure that each half of the new door has two hinges. Measure them out and attach them to the door and to the door frame on the wall as well.
