Here are the tables I plan to build.
There will be some changes. The basic end table will be built exactly as designed. The "sofa" table will be built to the width and length, the same height as the end table. That is because I want an "end table" that is narrow to fit between an easy chair and a wall. The third table will be a smaller version of the standard end table to serve as a plant stand. I may actually make 2 of those, I just haven't decided yet.
The tops of the tables are made from Baltic Birch furniture grade plywood, and there is considerable waste from the 2' x 4' sheets. I need to sit down and see if there is enough leftovers for the size plant stand tops I need. The plant stands have to have enough spread between the legs to be sturdy enough to prevent the cats from knocking them over. I am considering making the plant stand tops round, but I might make the square just for consistency of design.
I might have to angle the plant stand legs outward or attach them to a larger plywood base for stability. I might build the coffee table, but I'm not sure where I would put it. As I don't have a sofa, I'm not sure where I would use it. I might build one taller to use as an eating surface. I like to watch science&nature TV while eating, and TV trays are wobbly.
