A key question is to consider how large to make the hangar. The first thing to consider is the 2000 square foot question. Most codes in the United States differentiate between hangars less than 2000 ft. and those that are larger. In general, commercial codes apply to larger hangars whereby easier residential codes will apply to the smaller hangars. This can affect the pricing.
The structure over the hangar door is an important consideration. Hangar doors are usually quite wide varying from a minimum of 40 feet on up to greater than 55 feet wide. The header or beam spanning across the top of the door needs to be considered structurally. One way to handle this is by placing a steel I-beam across the door which will hold the weight of the roof. There are several disadvantages to this including higher construction costs due to the steel fabrication issues. Another disadvantage is that the beam bottom will usually fall well below the ceiling of the hangar causing the hangar door to be shorter than the ceiling height. Another, perhaps better, way to handle this is to use some sort of a gable roof or a modified gable roof over the hangar door. This allows the truss system of the roof to act as its own beam. Often the truss that spans over the door is a multi-ply truss and its bottom can be even with the ceiling height of the hangar. This allows the door to be higher and nearly the same height as the ceiling of the hangar. When designing the hangar discuss this aspect with the designer engineer who will work with you to determine the best solution.
Another common point to consider is whether or not to connect the hangar in the home. Connecting or not connecting each has its advantages and disadvantages. Connecting the hangar to the home is considered by most pilots to be quite advantageous. It allows one to stay out of the weather. It makes for some very interesting architecture. But if you are looking to build projects then you need to consider the impact made by these projects such as sounds and smells which you may not want to enter into the home. In such instances building the hangar and home separately may be the way to go.
Important design elements
How do you intend to use your hangar? Obviously, one intends to put an airplane in the hangars but many folks user hangars for other functions as well. Hangars usually become storage bins. Like everything else this can be controlled. But common uses of hangars include workshops, storing boats, storing cars - especially if you are looking not to build a separate garage, and storing motorhomes. Regarding motorhomes, modern motorhomes are generally greater than 13 feet in height above the floor when you consider their air-conditioner. That and the height of your airplane may be the determining factors as to how tall to make your hangar ceiling. These also affect the height of the door. When considering your hangar make certain that you predict, as well as possible, its ultimate uses.
