A Deviation from this project with a twist instead of a cat house it is a bird house. https://projects.xtool.com/inspiration/2445
Step 1) Starting this project with a circle, it is then changed to the desired shape with the use of other ovals and the combine feature. Along with this shape the body needs to be created again with a rectangle and more ovals the lower body is also created. Once you have the main body of the bird house a door and a opening is created.
Step 2) This step the border of the opening and the door are created this wood is now going to be walnut the front, back and bottom and sides are all birch.
Step 3) Each piece of the bird house is created using walnut or birch, in these steps the border for the door and opening are made along with the roof lats, all of these are made from walnut, in the next canvas the pieces for the back, the 2 sides and the bottom are also made but using birch. Canvas 1, 2, and 4 and birch and canvas 3 is walnut.
Step 4) All glued up, the bottom receives the sides then the front and back are glued together to create an open box. At this time the walnut slats are glued along the 4 curved area's creating the sides and the roof. If you like this follow me and give it a thumbs up!
