I bought a kit for the whole boat. It saves time and add some precision. I am building it in a single car garage. It is tight, with a total of 6 inches of clearance at the ends. My « workshop » is in the basement under the garage, this is where I made the keel. Until now I am very pleased with the plans and building method.
It looks like you are utilizing the space very well! I have done one kit boat so far and I must say it is very nice having everything already ready for you to assemble
