DIY Cat Tree Wood House Build Plans

We finally got our kids the pet they’ve been begging for over the last 5 years. And, I’m so happy to say she’s the sweetest kitty ever. I know, I know everyone thinks their pet is the best. But ours actually is the best. 😉

I’ve been a lifelong cat owner and lover. They’re just great, low maintenance pets for a busy home. I love dogs too. But, I prefer a pet that I don’t have to bathe regularly, walk, and let out for frequent bathroom trips. I’m a busy gal.

I lost my last cat just before getting married, 10 years ago. And, I assumed that I’d never have one again, due to my husbands allergies.

BUT, during a weak moment with our boys the hubby promised them a cat. LOL. And, I immediately got to work researching the best cats for someone with allergies. Turns out Siamese breeds generally have less of the proteins that cause allergic reactions. And, female cats tend to produce less than males.

So, I crossed my fingers and headed to our local pet rescue. The very first kitten I saw that day was this sweet, female Siamese mix. She let me hold her and was purring up a storm. That was good enough for me. I adopted her on the spot.

She’s been a member of our family for 4 months now and we are all crazy about her. And, luckily, my husband hasn’t been reacting to her. So, I’m not sure if it’s because she’s part Siamese or not. But, it’s fantastic news.

Is It Cheaper To Build Your Own Cat Tree?

Yes, it can be a lot cheaper to build your own cat tree. And, most of the cat trees or cat towers you can build at home will be bigger, sturdier, built from better, longer lasting materials, and definitely prettier than most of the cat trees they sell online.

You can build this cat tree for between $63 and $90, depending on what materials you want to use. This DIY cat tree wood house and cat tower combo is pretty tall at 71″. So, cats love that they can get up high on this cat tree.

Many cat tree’s and towers online look tall in pictures but when you check the dimensions, they’re only 4 or 5 feet high. And, even if they are tall, most store bought cat trees are made from cheap materials that fall apart quickly or just look bad.

In fact, most of them are covered in pretty ugly carpet colors that never match anything. I work hard to make my house look nice. I don’t want to buy a giant cat tree that looks cheap and not at all stylish. Right?!

That’s why I decided to design and build my own DIY Cat Tree Wood House / Cat Tower. 🙂

This DIY Cat Tree Wood House or Cat Tower is 71″ tall, easy to clean, and prettier than most expensive store bought Cat Tree’s.

I added a couple soft cat beds for napping.

What You Need To Build This Wood Cat Tower

As of May 2021, buying the ½” plywood, 1x2, and 4 1x3’s will cost about $90 in Texas. Or, you can use Cedar fence pickets instead of the 1x3’s and the total cost will only be $63. But you will need to resaw each picket into 2 – 2 ½” wide pieces.

Tools Needed

Materials Needed

  • 1 – 4’x8′ 1/2″ Thick Cabinet Grade Plywood
  • 1 – 8′ Long 1″x2″ Cedar Board
  • 4 – 8′ Long 1″x3″ Cedar Board (Home Depot Sells These)
    • OR 2 – 6’ Cedar Fence Pickets

DIY Cat Tree – Steps to Build

Quick Step Guide

  1. Cut the Plywood Pieces and Sand
  2. Build the Upper Cat House
  3. Build the Lower Cat House
  4. Paint the Cat Houses & Shelves
  5. Cut the Cedar Parts & Sand
  6. Attach the Wood Cat Houses with the Posts
  7. Attach the Shelves to the Cat Tower

Please Note: The full steps, with measurements, are only available as a download. BUT, the steps below will give a pretty good idea of how to build this tree.

I love that the painted wood build means that it’s easy to clean this cat tower. And, I can keep adding on little toys, ramps, and scratching posts over the years.

Step One

Start by cutting the 1/2″ plywood pieces for the 2 Cat Houses. The lower cat house is a few inches longer than the top. Each cat house has 2 or 3 openings in different spots to make it more fun for the cat(s). And, to give them different ways to jump around on this DIY Cat Tower.

Sand all of the plywood pieces with 150 grit to smooth the faces and edges.

Step Two

Start by building the upper, smaller box. I used my brad nailer and wood glue to assemble this box. The back of the box sits between the side pieces.

Start by gluing and nailing the side pieces to the back piece. You can see how I managed to do this without help in the build video, above.

Then I attached the bottom of the box. Again, this piece sits inside the sides. There will be an opening behind this piece to let the cat get into the box from underneath. Use glue and brad nails on the 2 SIDES.

The easiest way to attach the bottom is to just slide the bottom into place on a flat surface. Make sure the front edge of  the bottom is flush with the front edge of the sides.

After the bottom is attached, flip the box over to glue and nail the top into place, along 3 SIDES. Again, this piece sits inside the side pieces. BUT, the top should be attached all the way back against the back of the box. This will leave an opening at the front of the box on the top. That will give your cat access to climb on top of this box.

Next, mark the house cut out on the front piece. I have an easy diagram for this in the PDF build plans. After cutting out the opening with a Jigsaw, glue and brad nail the front onto the rest of the box.

The front sits in front of the sides and bottom. Be sure to use glue and nails on all 3 sides for a strong box.

Cat’s can jump into the upper house through the opening along the back on the bottom of the cat house.

Step Three

Now on to the lower, larger box that works as the base for this DIY Cat Tree House. The dimensions are slightly different but the build steps are the same.

Use a Brad Nailer and wood glue to assemble this box. The back of the box sits between the side pieces. Start by gluing and nailing the side pieces to the back piece. You can see how I managed to do this without help in the build video.

The back on this box doesn’t go all the way up. This gives your kitty a fun secret escape out of the back of the lower box.

Attach the top of this box with wood glue and brad nails. The top sits inside of the side pieces. You can flip the sides and back upside down, then slide the top into place on a flat, level surface to easily install the top.

Cut the same house shaped opening in the front of this box with your jigsaw. Then glue and brad nail the front onto the box.

The lower box doesn’t need a bottom, just be sure to build the box carefully so that all 4 edges sit on the floor nice and flat.

If you complete this build and find that the bottom isn’t sitting flat on your floor, you can level it by adding a bottom. Or, even just setting it on a rug could eliminate any slight wobbliness.

Cat’s can access the top of the upper cat house through the opening along the front of the top of the cat house.

Step Four

Now that both boxes for this DIY Cat Tree Wood House and Cat Tower are built, fill all of the nail holes with wood filler. Let that dry, then sand the patched holes and edges of the house shaped openings you cut with the jigsaw with 150-grit sandpaper or a sanding block.

I went with a mix of painted plywood and cedar on this build. In this case, I decided it was easier to paint both of my plywood boxes before attaching the cedar.

I dusted the boxes clean. Then painted both boxes, inside and out, with 2 coats of an off white Homemade Chalk Paint that I make with Latex Wall Paint and Plaster of Paris. Chalk Paint is easy to work with because it doesn’t require a primer, dries fast, cures hard, and it sands nicely.

Paint the 3 shelves you’ve cut with 2 coats of chalk paint too. You’ll also need 6 blocks to use as supports for those shelves. You can use ¾” blocks of Cedar or scrap wood you have leftover from previous projects.

I used 1x2 scraps that I cut to 2” long. If you don’t have scraps, use cuts off the 1x3 cedar.

I love Cedar. It’s a little harder to work with but looks beautiful. Check out this DIY Chevron Wood Wall Art or this DIY Wood Mosaic Table Top to see 2 of my favorite Cedar projects.

Step Five

The last step on the boxes is to glue and brad nail on the 1x2 cedar frame around the house cutouts. The easiest way to cut the cedar pieces is with a Miter Saw.

Cut the pieces out, sand them smooth with 150-grit, and dust them off. Then use glue and your brad nailer to attach the pieces to the front of each box.

You can fill the holes with wood filler, let dry, then sand and seal the Cedar. OR, you can use a matching wood putty AFTER sealing the cedar with a water-based poly. I used this Matte poly.

Cut 4 – 71” long cedar boards that will be used as the posts on this DIY Cat Tree Tower. Use either 1x3’s or 2 ½” wide strips of ½” thick cedar pickets.

Cut the top of each board with a 45 degree angle. Then sand the posts to get them ready for assembly.

Step Six

It’s time to build the cat tower. Glue and brad nail the 4 boards onto each box. The boards should be flush with the back of each box.

If you’re working alone, the easiest way to do this is to lay the top and bottom boxes on their sides to easily line up and glue the boards into place on one of the sides.

The board closest to the front will be lined up with the edge of the smaller, top box. That will make it 3 ½” back on the larger box. Repeat the gluing and nailing of the other 2 – 71” boards on the other side of the Cat Tree Tower.

Stand the Cat Tree up for the next part of this step. Then cut 2 – 18” long pieces of 1x2 to glue and brad nail into place under the upper box at the front and back.

These will help to support the weight of the upper box. It may be overkill, since the 4 “legs or posts” support the weight of the top box. But, better safe than sorry. And, that little bit of extra cedar looks nice anyway.

Fill the holes with wood filler, let dry, then sand and seal the cedar. OR, you can use a matching wood putty AFTER sealing the cedar with a water-based poly. I used this Matte poly.

I only sealed the cedar on this project. I didn’t need to seal the chalk paint. It’s tough enough on it’s own. But you can give it a top coat with the same poly, if you want.

Step Seven

Now you can add the 3 shelves. I spaced these out so that it makes going up and down the Cat Tree easy enough but still a little exercise.

Glue and brad nail the blocks that will support the shelves onto 2 of the posts. Use a level to make sure they are level. Then glue and brad nail the shelves to the supports.

Make sure the shelves are off center on the supports so that only 3” of the shelf sits in the space between the posts.

I want to suggest some fun optional additions to customize your cat tree.

You can make the shelves and tops of the 2 boxes less slippery by stapling down carpet remnants, using Mod Podge to glue down burlap, or by hot gluing some jute placemats down.

Add a soft cat bed inside the bottom level, like my star covered bed. You can also replace a shelf with a fun hammock, if your cat likes those.

You can hang some cat toys from the shelves or off the boxes. Or, add a scratching pad on top, nearby, or even build it onto the side to use as a ramp.

That’s it! You can grab the printable build plans with 3D Drawings and all of the measurements below.
