What Should You Consider When Building A Two-car Garage?

Building A Two-car Garage

When deciding the size of garage you need, there are various things you need to consider. 

This includes:


The height of your cars should be a benchmark for how high you will want your garage to be. The carry-ons, your vehicle antennas, and lights in your garage ceilings have to be incorporated in the calculations too. You should also consider adding some height if you want to use the top for storage, e.g., to keep a kayak. 

The Width

A squeezed garage poses a risk of damaging your car as you open the doors. Anytime you have luggage, it becomes hard to take them out without major hustle. Ensuring your garage has adequate space is a priority.

Proper clearance is also useful to perform different activities around your car. Most people use garages for more than just parking cars. Storage cabinets and workshop desks can be installed in the garage. You will need to consider all this when deciding on your garage width.

The Depth

Being in a position to walk around your parked car with ease should be as easy as possible. Most times, the depth of the garage is overlooked as it is considered an arbitrary factor. Having your car fit in the garage and the door closed with no space left is not enough; you need an allowance on both ends.

The Function Of Your Garage

A garage is not just a space you use to park your vehicle; you may want to use it for many other purposes. So, if you’re going to use your garage for other different tasks, you need to consider how much space they will take and incorporate it into your measurements.
