This step by step woodworking project is about insulated dog house plans free. If you want to protect your pet from extreme weather, you should consider building an insulated dog house. In most of the aspects, building a dog house with insulated walls is almost the same job as making a regular one. The only things you should add to the construction is rigid foam sheets and the interior plywood walls. Don’t forget that you should adjust the size of the dog house, according to the needs of your pet.
There are certain aspects you should pay attention to, as to obtain a professional result. Pre-drill the lumber before inserting the screws, to prevent the wood from splitting. In addition, align all the components at both ends before inserting the screws. Don’t forget to plumb the walls with a spirit level and to ensure the top ridge is perfectly horizontal. Measure the components several times, before cutting them, otherwise they might not fit together properly.

Dog house with insulation
Building an insulated dog house is a great project, especially f you want to protect your pet from coldness during wintertime and from hot weather during summer times. If you want to get the job done by yourself, you just should use proper plans for your needs and buy quality materials.
Top Tip: Build the frame of the dog house out of 2×2 lumber. Fit 1 1/2” thick rigid foam insulation sheets inside the frame of the dog house. Attach 5/8” grooved siding to the outside of the frame.
Insulated Dog House Plans
The first step of the project is to build the base of the dog house. Therefore, build the joists from 2×4 lumber and assemble the frame together with 3” screws. Ass you can see in the image, you should align the components at both ends, before driving in the screws.
Pre-drill the rim joists, to prevent the wood from splitting. In addition, make sure the corners are right-angled, using a carpentry square.
The next step of the project is to build the flooring from 3/4” plywood and to secure it to the joists. Before driving in the 2” nails to the joists, every 4”, you should make sure the edges of the sheet are flush with the frame.
Top Tip: Use a circular saw with a fine blade to get the job done quickly. Place the blade of the saw over the cut line and get the job done accurately on all edges.
Build the frame of the walls from 2×2 lumber, on a level surface. Secure the wall studs to the bottom and top plates, making sure the corner are right-angled. Insert the 3” wood screws, after drilling the pilot hole trough the plates.
Top Tip: Place the frames on the flooring, making sure they are flush with the side edges. Pre-drill the plates, before inserting the 3” screws to the flooring. Plumb them with a spirit level.
Building the front and the back faces of the dog house is a straight forward job, if you use the same techniques described above. Measure the distance between the side walls, before cutting the wooden components.
As you should notice in the plans, you have to leave enough room for the door opening. Double the walls suds, to provide support to the exterior siding around the opening.
Build the exterior walls from 5/8” siding or 3/4” plywood, using the free plans. In order to make accurate cuts, we recommend you to draw the cut lines on the sheets and use a circular saw with a fine blade. Secure the pieces to the frame with 1 1/4” nails.
Cut the door opening with a jig saw, after drilling a starting hole with a large drill bit. Make sure the walls are plumb, before attaching the siding.
In order to protect your pet from extreme temperatures, we recommend you to fit 1 1/2” rigid foam insulation sheet between the wooden studs. Therefore, cut the sheets to the right size with a hand saw. Afterwards, place them between the studs, in all the cavities.
If you want to install thicker insulation sheets, you should consider building the frame from 2×4 lumber. Nevertheless, in most of the cases, the 1 1/2” thick foam sheets will get the job properly.
Continue the project by fitting the interior walls, made out of 1/4” plywood. First of all, you should install the side panels, after measuring their size. Fit the plywood sheets into place and secure them with 1 1/4” along the frame, every 6”.
Next, install the back and the front interior walls, in the same manner described above. Make sure the sheets are in a good condition and the nails are inserted properly, otherwise the pet might injure.
Build the rafters from 2×2 lumber, making sure you cut their ends at 45º. All the rafters should have the same shape and size, otherwise the roof won’t have a symmetrical look.
Top Tip: Fit the rafters into place, align them thoroughly at both ends and lock them to the top plates with 3” screws. Pre-drill the rafters with a drill machinery, to prevent the wood from splitting. Join the rafters together at top, using several 2 1/2” screws.
In order to get the job done like a professional, install the interior 1/4” plywood panel and fit the 1 1/2” thick foam sheets between the rafters. This step is essential for the insulated dog house, as you need to keep the construction well protected against bad weather on all sides.
Ensure there are no gaps between the foam sheets and the rafters. If there are gaps, the cold air will get trough and cool the interior of the dog house.
Use the same techniques described above to install the insulation boards on the opposite side of the dog house, before installing the roofing sheets. As you should notice in the image, you have use 3/4” plywood and 2” wood screws, to secure the sheets into place.
Leave a front and back overhang of 1 1/2”, if you want to get a beautiful appearance. Make sure one side of the roofing cover the other one.
The next step of the woodworking project is to cover the roofing sheets with tar paper and secure it into place with staples. Then, install the asphalt shingles starting with the bottom left part of the roof, making sure they cover the trims.
Top Tip: We strongly recommend you to snap a chalk line to guide you when installing the shingles. In this manner the rows will be perfectly parallel, from bottom up to top.
Last but not least, you have to take care of the finishing touches. Fill the holes with wood putty and seal the gaps with a waterproof filler. Let the compound dry out for at least several hours before sanding the surface with 120-grit sandpaper.
Top Top: Apply several coats of paint, in order to protect the insulated dog house from rot. Add the 1×2 trims to the exterior walls, to get an unique design and a neat look.
