How to Build Double Height Ceiling House Additions

What You'll Need
Circular saw
Fiberglass insulation

As far as house additions go, few people immediately think of making use of the space afforded to them by their high ceilings. Large, open spaces are almost always desirable in homes. Homeowners frequently admire high, vaulted or cathedral ceilings and the elegance they impart to a room. However, in the early 21st century, as the economy faltered, homeowners began to see problems with high ceilings. They cost more to heat and cool, are difficult to clean, and are seen by some as wasted space. It is becoming more popular to build a room in the space that the high ceiling occupies. These additions get rid of the difficult-to-maintain ceilings, and can add an additional 300 to 400 square feet to your home.

Double height ceiling rooms are not for everyone. They can be costly to build and can remain difficult to heat and cool. However, for those who would like to use as much space as possible in their homes, they are an excellent use of the "wasted" vaulted/cathedral ceiling space,


Step 1 - Safety

Be sure that you take adequate safety precautions before undertaking any construction project. Because adding a room to your home is particularly dependent on the integrity of your work, it's important that you take as many precautions as possible. Wear the appropriate safety gear (especially goggles), have a capable partner available to help you on complicated tasks, and always be sure that the modifications you wish to make fall within the borders of local rules and regulations. If you need a permit, get one before attempting to add onto your home. Have an expert evaluate your space to see if adding another room is possible without professional equipment.

Step 2 - Framework

Have a clear idea of the layout of the room you want to build. It's a good idea to make some simple blueprints, so that you are well aware of your electrical and, if necessary, plumbing needs.

You will need access to the area you're working on, so you will probably need to either cut a large, temporary door into a neighboring door or hallway, or install a temporary staircase. Thread your wiring through the joists (the horizontal, load-bearing beams), and install all of your wiring for lights and outlets. Be sure to insulate floors, ceilings, and walls well before you install your sub-flooring, as garages rarely heat or cool well. Fiberglass is the cheapest and most commonly used insulation. You can nail it into place.

Step 3 - Fleshing Out Your Room

Once you are satisfied with the insulation and wiring in your in-progress room, you can nail in your drywall. Any built-in storage areas, such as bookcases, should be added after the drywall is installed.

Once your drywall has been installed, you can install flooring. You can either lay down carpet, or take the time to install wooden floors. After that, you can add your molding and baseboards, as well as your light fixtures and wall outlets. Convert your temporary door into a permanent doorway. Since your temporary entryway should be much larger than the doorway will be, you may wish to move any large furniture into the room before converting your temporary entryway into a permanent door.

The steps outlined here may not cover every issue you may run into when building your own room. Do not be shy to consult a professional for information regarding safety or technical issues regarding your new room.
