1. Proper lighting
Garage lighting fixtures are very important when it comes to the safety aspect of your garage. As mentioned earlier, if you are going to be working with power tools and other equipment that could potentially injure you, proper lighting is essential. You need to make sure that you can always see what you are doing at all times. In the part of the garage where the power tools are being used, there must not be any shadowy areas where a saw blade could be obscured. Lighting is something you can never have too much of in a garage environment.
You have most likely paid a lot of money for your tools. Because of this significant investment on your part, you should buy a heavy duty toolbox to protect your tools from moisture, damage and theft. There are toolboxes you can buy that have wheels which make it easy for you to move around. If you are going to need constant access to your tools and your do not feel like walking over to your toolbox very often, you should consider buying one with wheels. Make sure you buy a model that allows you to lock each individual drawer.
You can also never have too many cabinets. Storage space is vital for your garage, especially if you are going to be using lots of tools and equipment. While some of your tools can fit in your toolbox, you will need a place to store some of your larger power tools. Since you will not be able to hang everything on the walls, you should install some quality cabinets, preferably made of a strong material like stainless steel.
