This step by step diy project is about insulated cat house plans plans. I have designed this outdoor cat house so you can protect your favorite furry pets from the elements. The cat house is built on a platform, so the cats can climb it and also be protected from other animals. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

Building a cat house
The first step of the project is to build the frame for the floor. Cut the components from 2×4 lumber, using the information from the diagram. Drill pilot holes through the rim joists and insert 2 1/2″ screws into the perpendicular components. Make sure the corners are square and add glue to the joints for a professional result.
Fit polystyrene foam sheets between the frame of the floor, as shown in the diagram. Make sure you fit several layers of the polystyrene, as a better thickness will ensure a better insulation for the floor of the cat house.
Next, you need to seal the floor with 1/2″ plywood sheets. Align the edges with attention, drill pilot holes and secure the sheet into place with 1 5/8″ screws.
Next, you need to attach the 2×4 legs to the frame of the floor. Use a spirit level to plumb the legs when attaching them to the floor frame. Drill pilot holes through the top of the legs and secure them to the floor using 2 1/2″ screws.
Build the front wall frame from 2×2 lumber. Drill pilot holes and insert 2 1/2″ screws to lock everything together, as shown in the plans. Make sure the corners are square and check if the edges are flush. Add glue to the joints to enhance the bond of the components.
Build the two side walls in the same manner described above. Drill pilot holes and insert 2 1/2″ screws to lock everything tightly. Add glue to the joints and make sure the corners are square.
Build the back wall from 2×2 lumber. Drill pilot holes through the plates and insert 2 1/2″ screws to lock the components together.
Fit the wall frames to the floor of the cat house, as shown in the plans. Drill pilot holes through the bottom plates and insert 2 1/2″ screws into the floor. In addition, lock the adjacent walls together by drilling pilot holes and inserting 2 1/2″ screws.
Fit 1/2″ plywood to the sides of the cat house. Align the edges with attention and secure them to the framing with 8d nails.
Build the rafters for the cat house from 2×2 lumber. Cut one ends of the rafters at 55 degrees, by making a 35 degree cuts. In addition, you need to cut out a birds mouth in the rafters, so they can be secure to the top plates tightly.
Fit the rafters to the wall frames, as shown in the plans. Drill pilot holes through the rafters and insert 2 1/2″ screws to lock them together tightly. Leave no gaps between the components for a neat result.
Build the front wall from 1/2″ plywood, using the information from the diagram. Cut out the door opening for a professional result. Smooth the edges with sandpaper and secure the walls into place with 8d nails.
Build the back wall in the same manner and secure it to the frame with 8d nails, after aligning the edges with attention.
Make sure you read PART 2 of the project, so you learn how to build the roof for the outdoor cat house. In PART 2 I will show you for to install insulation in the walls, as well into the roof.
This is a simple project you should be able to build in a few days without much effort. This insulated cat house is a must have project if you want to protect your favorite pets from cold weather.
