He is worried about the expensive Porsche that is sitting outside in bad weather. The reason could be any of the following:
The garage does not have room for one more car. The garage door is broken or there is a problem with the structure of the garage. There is plenty of space left but it is unoccupied and not used. The garage was made with a particular type of car in mind. Or on the other hand, the house does not have a proper garage at all.
All of these problems have only one solution, and that is for you to step on the gas and get going with your woodworking skills. The web will help you in all possible steps. Instead of going through a rather complicated manual where pictures are scribbled in fine print and final parts are difficult to assemble, you can choose to harness the power of the internet and finish the workshop in a week.
Nowadays, to start up a garage, you have to have the whole plan laid out, since it is not a single piece of furniture and you have the complete element of building a house. For example, the garage door, shelves and any other functional cabinets, and the toolbox. The walls and ceiling of the garage, if made with wood, should be available in the DIY plan. And it really helps to find help building it.
There are sites where you can look up blueprints for the individual parts and then assemble them yourself. There are other places where general garage plans are available. You can choose the garage you want, either 1 car or 2 cars or more. A beautifully designed site with hundreds of images and illustrations speaks volumes about the hard work put into making this a favorite for everyone planning to build a garage of their own.
