Door canopies protect the door and the surrounding area from sun and inclement weather. This makes entering and exiting the house much more pleasant, especially on the nights when you simply can't seem to get the key in the door. Many prefabricated door canopies are available, however, designing your own is simple. With a little time to spare and a few simple supplies, you can design your own door canopy for your home.
Measure the dimensions of your door and record the measurements on the lined paper.
Add 60 cm (2 feet) to the width of your door; this will be the width of the door canopy. Extending it 30 cm (1 foot) out on either side ensures protection from the elements when standing beneath the canopy. Write down the measurement.
Add 30 cm (1 foot) to the width of the door; this will be the depth of the door canopy. Extending it 30 cm (1 foot) out ensures that it will be long enough to provide protection from the elements while it remains short enough to be supported by the base width. These measurement alterations are common practice in residential design, according to Edward Muller, author of "Reading Architectural Working Drawings: Residential and Light Construction."
Divide the height of the door by 10; this will be the height of the door canopy. The height is divided by 10 so that it will look proportionate to the height of the door.
Using these measurements and your ruler, sketch a scaled down version of the door canopy on the graph paper. A good scale to go by is two squares on the graph paper to every 30 cm (1 foot) in length.
Sketch different design ideas until you create one that you like best. Base the construction of your door canopy around this design.
Choose the material that you would like to use for your door canopy. Canvas is a common fabric from which door canopies are often crafted. It is available in many colours and patterns; canvas is also considered the most cost effective door canopy material. Other materials, such as shingled roofing or stone, can be used to craft the door canopy. The material should match or accent the overall exterior design of your house so that the designs flow well together.
Once you've laid out the design of your door canopy, you should consult with a construction professional to finalise the plans.
