HOW I BUILT CUSTOM BUILT INS ALL BY MYSELF!

In all my days of DIY, this has been my biggest project to date. And you know what? I’m super dang proud of how it turned out! It took me about 2 weeks, but if I were to add it all up it was only 3 or 4 days worth of actual work because you know, stay at home mom. I love how custom built-ins can just make a space. My niece asked me if I would build her some in their house they just bought, and I jumped on the chance because I’d always wanted to build some. I’m just counting down the days until my husband and I can buy a house of our own so I can give it a good DIY treatment MY way.

Getting Started

I was a little intimidated at first with this project, but decided to jump in head-first and get it done. I started by taking the measurements of the wall and getting a feel for the kind of built-ins my niece wanted. Then I took what I had in my head and sketched it out on some graph paper so I knew exactly what I wanted it to look like, what dimensions it needed to be, what materials I needed to buy, and every cut I needed to make. This is where things start to get REAL technical. It’s important when you do this step to think of EVERYTHING. There were a couple of minor blunders I made during this step that set me back just a little bit, but it all turned out okay in the end, and I didn’t end up too far off the estimated budget. The entire build cost a little over $430, not including paint.

This is one of the several graph pages I drew out that outlines how I needed to make my cuts on each piece of MDF. In this case, 1 square = 4 inches.

Materials

*Amount of materials are based off of my wall dimensions, which were 11 feet long by 9 feet tall. Yours may differ.

  • 6 sheets MDF **Note: After more experience working with MDF, I only recommend it in certain circumstances. Paintable plywood would be a better option here for durability purposes.**
  • 5 – 2 x 4 x 8 boards
  • 160” crown molding
  • 3 2x12x8’s OR 1 2x12x8 and 2 2x8x8’s for counter top
  • Paintable Caulk
  • Wood glue
  • 1 1/2” screws
  • 1 1/2” Brad nails
  • Paint
  • 1 sheet 1/4” plywood or more if you want to add backing to your shelves before installation
  • 160” Decorative trim for header

Tools

Begin the Build

Rectangle wood

After I removed the baseboard from the wall, I built some simple boxes with 2×4’s to act as the base for the lower cabinets, making sure to add 4 inches to the middle section for a little deeper shelving. I attached these to the wall studs with 2 1/2″ screws.

Next, I built the basic bookshelf structure for the lower portion out of 3/4 inch MDF. Hint: If your bookshelves are going to be longer than 32 inches in width, MDF will eventually start to bow if not properly reinforced. My shelves here are 36 inches, so I factored into the build some extra material that I will show you later on.

Bonus points if you have a table saw! I made all of my cuts with a circular saw and saw guide which took much longer, but it can be done! If you’re brave and 100% sure of your planning, you can also have some of your long cuts made at the Home Depot or Lowe’s for free when you purchase the MDF.\
Wood bookshelf
I built two identical shelving units for the sides that were 10″ deep. For the middle section I added 4 inches which made it 14 inches deep, and was a grand total of 72 inches wide with a middle divider.

I measured and attached the shelves with a combination of brad nails and screws, but you’re going to want to be careful about where you place your screws on the middle section, because if they’re found in the first 4 inches of the middle shelf, they will be seen! Learned that one the hard way.

Next, I attached my shelving units to the wall using screws where they wouldn’t be seen in upper corners and brad nails everywhere else there was a stud in the wall.

Now looky here! Things are starting to get exciting! Also, don’t forget to attach the shelving units to EACH OTHER as well.

Wooden bookshelves
Don’t worry if your shelves have gaps in between. Most homes do not have perfectly square walls, so while I was nice and tight at the bottom of my shelving, I had to use some shims to tighten things up at the top of my shelving. These gaps will be covered with my counter top and the trim.

From here, I decided to finish the lower portion all the way with the trim before I built the upper bookshelves. I ripped 3 inch strips of MDF, cut them to size, and brad-nailed and glued them to frame out the sides of the bookshelves. I only cut out 2 inch strips for the trim that divided the shelves, and 4 inch strips to cover up the base of the shelving where the baseboard would be reattached. It added such a nice finished look, don’t you think?! I also built the counter top with another layer of MDF and trimmed it out.

Note: MDF is NOT the best material to use for a counter top. If it gets wet (i.e. someone sets a cold glass of water on it) the MDF will swell up and it will only go away with heavy sanding and re-painting. I ended up using several heavy layers of this clear coat to water-proof this counter top. If possible, the top should be made of solid wood or another sturdy material which you can do quite cheaply with 2 x 12’s attached together. The reason we did not do this because at the time the 2 x 12 selection was poor and we could not find any straight pieces. I also do not own the tools to mill my own. Another option would be to use MDF that has been laminated.

Edit: I would also NOT recommend building the face frame with MDF. This should be done with solid wood (which can be done inexpensively by using pine or whitewood). The MDF just isn’t solid enough to hold the hinges in place for very long with the doors constantly swinging open and closed. Wood is much better suited for this and will last longer.

Wooden bookshelves

Upper Shelving

Next, repeat the same steps for your upper bookcases. To attach each bookshelf to the frame, I used screws on the sides that we’re going to be up against the wall. On the sides that we’re going to be visible, I glued and attached them with A BUNCH of long brad nails. You’ll want to make sure you use a level and a square when attaching the shelves to make sure they don’t tilt one way or the other. I also made sure to leave plenty of room at the top of my bookcase for the headers.

I built these to be 10 inches deep.

I attached these to the studs in the wall as well, this time only using long brad nails.

At this point I was ready to brace up my shelving. I used long square wooden dowels, lined them up underneath each shelf with the front of each shelf, and used brad nails to secure them. I also did this with the shelves in the lower portion that I had already covered with the frame. I didn’t grab a picture of it, but I also used strips of quarter round to brace up the back of the shelves as well. I chose quarter round because it would be seen, and it makes for a nice-looking trim.

I then cut and nailed on my header boards. I wasn’t too concerned with getting them all the way to the ceiling because I knew I’d be covering up the gaps with crown molding.

Up until this point, my niece was undecided if she wanted the header to extend across the whole length of the wall. I thought it would add a nice touch, so I talked her into it. Had I known we were going to do it, I probably would have gone about things a little differently and extended it across the top the bookshelves on either side so it had something to rest on. Instead, I ran some cleats along the wall and the sides of the bookshelves that I screwed into the studs in the walls, and framed it in from those.

I didn’t show it in the pictures, but I also ended up adding cleats underneath the middle header after I nailed it up, just for added support. MDF is quite heavy and I didn’t want anything coming down over time.

The next step was to add the crown molding, a trim piece to cover up the seams (I also used putty to fill in the vertical seams and sanded it down so it wouldn’t show underneath the paint) and then put the baseboard back on.

The length of the entire wall was longer than 8 feet, and I could only find trim in 8 foot sections (not the crown molding, that came in 12 foot sections). To join them together without butting them up to each other, I just cut them at opposite angles which hid the seam much better. Once I caulked and painted, you wouldn’t know where one started and the other began!

My least favorite part of the whole building process is caulking, but it must be done, and I will say that it makes the whole project look like a million bucks when it’s finished. Before I painted, I caulked, and caulked, and caulked! I think all the caulking took me a full day of work. I made sure to get every seam I could find that would show.

Now on to the good stuff! It was time to paint! I used my HomeRight Finish Max paint sprayer I got for $60 off of Amazon. It’s a killer deal, and I love how simple and easy it is to use and clean! The air compressor is built in, so there’s nothing heavy to lug around. All you need is an extension cord and you’re in business.

Paint sprayer

Ahhhh. It’s so satisfying to see days of hard work finally pay off! I removed the TV and started to paint behind the wall behind the shelves. The color is called Fly-by-night Blue by Valspar paint. It was perfect! I wanted a beautiful dark Navy color without being too blue. I also painted several coats of water based Polycrylic on the counter top portion after it was painted to water-proof it.

The last step of the building process was to build the doors, which I totally spaced getting pictures of. But, since this post is long enough already I’ll just write a separate post about how I did that later. I hung the doors, added the hardware, and decorated!

Isn’t it beautiful???
