Since a garage is usually attached to or very near a house, it would be best to have a garage style that is like the house.
The four most common styles are: gable, reverse gable, hip, and gambrel.
A. Common types: gable, reverse gable, hip, and gambrel
Gable-style garages, where the two halves of the roof are symmetrical and join together to form a triangle, are the most
common type. The garage door is installed in one of the gabled ends. These structures are easy to frame and economical to build.
They also give great load-bearing capabilities as well as good drainage.
A reverse-gable garage is identical to a gable garage except one important difference. Instead of locating the door in one
of the gabled ends, the door is installed under the eaves on one of the long walls. It has the same features of the gable version;
this design is chosen over a gable mainly because it concerns how the garage lies in relation to the street.
A hip style garage has gabled ends that lean in toward the center. They might run all the way to the center, making a
pyramid-like roof, or they may run partially in, leaving a flat portion near the center. The complex roof line is harder to frame.
Gambrel garages are basically gable garages with two pitches on each slope. This makes additional head room and storage room.
The roof framing is complex, but simpler than for a hip roof.
B. Take-Measurements
With today's wider vehicles, it is important that you measure them and keep good enough spacing so you can get in and out
comfortably, as well as walk around inside the garage. Most garages are used for storage also, so make sure there's enough space
for that. Consider traffic patterns inside to make sure there's convenient access to car doors.
C. Plan your new Driveway
A new garage usually means adding a new driveway. In addition to the standard straight-to-the-doors design, you can opt
for a turnaround area or additional parking space. In most cases, short driveways are sized to match the width of the garage.
Longer driveways, on the other hand, are usually only single-car-width to hold down the paving costs.
