Floor plans are a necessity whether you are doing a small remodel, building an addition or designing a whole new structure. While you need not be an architect to draw up a simple floor plan, you should aim for accuracy to create workable plans that will represent a viable plan for the remodel or building effort. You can create simple floor plans with a ruler and graph paper, or with drawing software on the computer. The results will be fairly similar whether you go high tech or low tech.
Measure the room or area. You'll want to get an accurate measure of each wall and window. Always double check your figures to be certain. It's easiest to have a helper at the other end of the tape to pull it taut and straight.
Designate a rule for your measurements on the graph paper with a 1/4 inch grid. A simple method is to have a 1/2 inch on the graph paper equal a foot of length. This will be two squares on your graph paper. It's simple then to convert your measurements to the graph paper. For instance, if a wall is 12 feet long, divide by two and it will be six inches on the paper. That will be 24 squares.
Indicate walls by straight lines, windows by two parallel lines and doorways by an opening or blank space with a line drawn representing the direction the door swings open.
Cut out small pieces of darker paper in shapes to represent furniture if you are planning detailed elements of the design. Place in appropriate spots. Once you are certain, you can tape the furniture into the correct spot.
Try free software for drawing floorplans like Gliffy or free trials of floor plan software such as SmartDraw or Envisioneer Express if you'd rather use your computer to aid your drawing. You will still need your accurate measurements to create floor plans whether you use software or draw your own on graph paper.
