Slanted Wall built-ins, with Hidden Storage

I am happy to share (finally!) how I did the slanted wall built-in's, with hidden storage, in my sister's closet/laundry room makeover!

First off, I want to say thanks to all you amazing readers/friends, I so very much appreciate your wonderful comments!  You are the reason I take the time to do this blog, and it means a lot to me that you take the time to read it, so wrap your arms around yourself and squeeze tight...that was a big hug from me!  You are awesome!  Mmmuah!

MyLove2Create, Slanted Wall Built-ins
It seems like a million years ago since I did this and I have been dusting off the cobwebs in my brain, but pictures are my hero, and they like to tell the story anyway so here we go...

I believe I mentioned in the reveal that I arrived with ideas but no solid plan to get this closet done (in 6 days).  When I said I would help do this room I started a slanted wall board on pinterest, to collect ideas I liked.  I shared them with my Sister, Kaelynn, and her husband Royce.  Once we decided how it would be laid out, I set two work on getting measurements.  I would show you my sketches and scribbled on paper, but it got lost. :(
MyLove2Create, Slanted Wall Built-ins
I started by measuring the walls on both sides of the room, to see how wide they were.  I only measured on the floor and you will see later why that was a mistake.  Take measurements from wall to wall on the top and bottom and use the smallest measurement.  Not all walls are created equal or level, as I should have remembered.  I took that measurement and subtracted a few inches, then divided it by 3.  That gave me the width of the three sections... with a little elbow room for the middle section to roll out.
Measuring to cut the plywood at a slant
Since we decided to do built-ins on both sides of the room, we needed twice as much plywood.  That meant 6 sections total, two without shelves.  Which put me at needing 8 slanted side boards for each side of the room, or 16 total.  To make it easy and save on wood I bought 5 sheets of 4x8 foot plywood and had the nice guys at Home Depot rip all of them into 15 3/4 inch strips.  For the 16 slanted boards I only used 8 strips of plywood, and cut them on a slant (see above).  They were equal in size and I cut two boards at once with my circular saw.  So I got 4 slanted side boards with one cut, sa-weet!
Pre painting boards for built in's
I also cut the 6 bottom pieces for each section, and the 12 shelf boards out of the left over plywood strips.  They were all sanded, pocket holes drilled, primed, and painted with two coats of white paint.  Wow, that took me like, two seconds to type... but to actually do it took FOR-E-VOR (said just like in the movie the Sandlot).  Luckily Kaelynn and I both could paint, and wouldn't you know this is the only painting picture I could find?  I guess we were too busy to stop and shoot.  We had boards everywhere...
attaching shelves with pocket holes
It is so much better to paint first, I can't even imagine having to do it after everything was built!  For the outside sections I started by adding my shelves with pocket holes, making sure to measure and mark the placement first.
Attaching side wall
Then I added the other side, which I had measured and marked as well.  I used the bottom piece as a guide to make sure the ends were even at the bottom.  I clamped and drilled in the pocket hole screws.
Attaching bottom board
Next I added the bottom board.  Please note I am not using any glue.  Why?  Because if the shelves ever need to be taken apart it can be done without ruining them.
One section for built in's built
And lastly I added the other side slanted board.  I also used a small strip of plywood, left over from when the Home Depot guy cut all the boards, as a support board.  I used more of those small strips of plywood on the Old Deck Wood Laundry Crate I made for the room.  (can you see all the boards in the back ground?)
attaching support board
Here is a close up of how I attached the support board.
Building middle roll out section
To build the two middle sections I started by adding one slanted side board...
Using 1x3 board for support
And then the other.  I used a 1x3 for a support board on the top and bottom (not pictured) also attached with pocket holes.
All six sections built
Here are all six sections!  You can see some sides were not painted, that is because those would be flush with the wall.  Each section was numbered and marked so I knew exactly where they would go in the room.  While I was building these my sister was up stairs painting the room, and the floor.  It was very important that was done before we installed the built-ins.
Attaching white gloss hardboard panel for section backing
You may have noticed that the sections still didn't have a back.  We found the best solution for this and for such a great price!  We needed six backs and they needed to be white, but we did NOT want to paint them!  Kaelynn spotted some DPI 1/8-in x 4-ft x 8-ft white/gloss hardboard wall panel at Lowes,  It was only $13.47 a sheet and we were able to get two backs out of one sheet, so we only had to buy 3 total.  It was even more awesome because the guy at Lowes cut them for us too.  You better believe we were doing a happy dance in the isles!  I nailed them onto each section.  For the shelf sections, just used nails.  For the middle sections (see above) I nailed the sides and used small machine screws to attach them to the support boards.
Touch up painting on support boards
Here Kaelynn and Kathy were dancing priming the support boards, since we hadn't painted them yet. They are going to love this shot...hee hee!
Adding block for caster placement
The middle sections needed wheels.  Luckily the old deck wood was the perfect thickness combined with the castors to equal 3 1/2 inches tall.  The exact height of my 2x4 bases that the end sections would be sitting on (I will show you a picture in a second).  To make it easy I nailed on the block of wood to hold it in place then I...
Attaching caster wheels
Pre drilled holes and screwed them onto the bottom.  I got the castors on sale at Harbor Freight for only $1 each!!  I was super stoked about that.
Middle sections with top support boards
You can see in this picture that the middle sections were raised up to the perfect height.  The 2x4 base fits just under the section.  To build the bases I used 2x4's from pallets that I broke apart, so all four of them were free.  I had Royce build them by pre drilling holes and screwing them together.  Oh, and I used more plywood scraps for support on these middle sections, you see them at the very top.

With the walls and subfloor painted we were ready to install!!
Attaching 2x4 base to the floor and wall for built in sections to sit on
First up was securing the four bases to the walls and floor.  I drilled holes and screwed them to the floor and the stud in the wall.  Before I did this I did a dry fit with the section on top of the base to make sure the base was in the right place.  When it was where it needed to be I drew a pencil line around the base on the floor.  That way if it shifted by accident I could easily put it back in the right spot.
nailing on sections to 2x4 base
With the base secured, we just lifted the sections on top and nailed them right into the base.
nailing section to studs in the wall
The sides got nailed into the studs.  With all four sections in place it was time for the moment of truth...would the middle sections fit?  Ummm, no...Nooooo!!

Ok, remember when I said that I only measured the bottom of the walls?  Well the top of the walls were  not as wide, of course.  So the middle sections were too big by less than 1/4 inch.  I am not kidding!  I was a LITTLE upset, at my mistake.  It was about 1am at this point on Thursday night, or I guess Friday morning, and we were so tired.  But....
Taking apart middle sections so they can be cut down to fit, they were just over 1/4 inch too big
It had to be done.  We took apart the middle sections.  The backing, supports, sides, and bottom.  Then I went and cut off just under a 1/2 inch on both bottoms, backs, and supports.  Re-drilled pocket holes in the supports, and put both sections back together again.  And guess what?  They fit!
All sections fit along wall
Thank goodness for Royce and Kaelynn, I think I would have just cried and given up at this point without them!  They were so patient and helpful, I believe we finally went to be around 3 am.
Using a nail gun to attach trim
Friday morning Kaelynn, Kathy, and I headed to Home Depot to buy the trim.  Before we left I measured everything twice and had Kaelynn write everything down.  We spend forever laughing and figuring out which length of boards to get that would work best with the cuts we needed.  It was very apparent that my sisters think differently than I do and they thought I was speaking a foreign language with the way I reasoned and figured out the math in my head.  Needless to say, we were catching a lot of fun looks from people...because well, we may have been a little sleep deprived and silly...

We got home and I cut all the trim right in the room, we started with the baseboard trim, and nailed it on.  Then we did the top trim using 1x3 boards.  Can you figure out what my sister's are using for ear plugs?
cutting trim with miter saw
This is called rocking what you got people!!  That is me cutting trim, and Kaelynn is sporting the newest model of earplugs on the fly....tampons!  I know, I know, we. are. awesome.  The miter saw and nail gun were so loud in that room, my sisters finally realized that I wasn't crazy to always have my ear plugs in, and we couldn't find the extra pairs I had brought, so we made do. :)
using a 45 degree bevel for vertical trim
For the vertical trim we used 1x2's, except on the sides of the middle roll out sections, we used 1x3's. To make the trim blend better into the base moulding I cut the bottom ends at a 45 degree bevel.
Getting ready to attach vertical trim
Here they are ready to be nailed on.
Using a level to make sure the trim is straight
I showed Kaelynn how to make sure they were level and she set to work nailing them on, while I measured and cut the rest of the trim.  We make a pretty good team.
Close up of middle and side section and how trim is attached
For the 1x3's you can see I had her nail only to the middle section.  So when you need to pull it out, you just grab the trim and...
Close up of how middle section rolls out
Pull!  With the vertical trim attached, all we had to do was add the horizontal trim.  It is so important to measure and cut as you go, because trim is expensive, and it is always better to be safe than sorry, trim is costly.  I am sure you noticed the trim is already white.  We made sure to by the pre-primed boards so we didn't have to paint any more than necessary.  It was soooo worth it!
adding clothing rodsWith the shelves trimmed out all that was left was attaching the clothing rods.  I give a tutorial in my Master closet makeover, trim, shelves and rods post, on how to install them.  It is really easy, I showed Kaelynn how to do the one above, and let her do the rest.  While she did that I was building the DIY Upholstered Bench downstairs.
All rods attached ready for clothes
And here is the other wall, with rods in place.

Next up?  Filling in the nail holes with spackle, caulking the cracks, and painting the trim.  I put my sister Kathy and her husband Taylor to work on this fun project!  They were amazing, seriously!  This is a vital but tedious job, and I would have never been able to do the other building projects without their help.

When I stained the bare wood on the laundry crate, I ended up staining the rods as well.  I love the way they turned out.

The rods were the perfect color to match the room.

And even if I had to take apart the middle sections to get it was so worth it!

I am thinking these slanted wall built-ins went above and beyond our expectations.  Most importantly...

I hope this was helpful if you are planning to tackle a similar project.  Here is an approximate cost break down for my sister's built in's:

5 sheets of 3/4 inch 4x8 foot plywood @ 38.97 each = 194.85
2 inch wood screws 1 lb = 6.47
1 1/4 inch pocket hole screws, box of 100 = 3.97
Paint tray set= 12.97
White/gloss hardboard panels 3@13.47 = 40.41
8 caster wheels @ 1.00 each = 8.00
3 1x3 furring strips @2.12 each = 6.36
1 5/8 inch screws 1 lb = 6.47
Trim boards: 1x3's, 1x2's , base moulding, wood for closet rods, and rod holders, spackle and caulk (sorry no break down, lost receipt) = 140.00
and approx $25 in taxes

All other supplies we had on hand, including white primer and paint, free wood from pallets for 2x4 bases, nails and nail gun, extra pocket hole screws...

So... for the Slanted Wall Built-in's, with hidden storage we are looking at a total of $444.50  we could even round it up to $450 to cover any misc item I may have missed.  That is not too shabby!  For the whole room makeover it was under $600, and done in about a week, that is what I call awesome!

Thanks for reading!

  13. Wow! You are amazing! I am totally inspired by what you managed to create, how fast, how cheap and with such an amazing attitude! Pheuff! Blown away! Well done xx

  14. Great layout, I have been forever going back and forth about what to do with a 47 in knee wall that runs the length of my bedroom. Was able to adapt this to what I'm going to do... The idea of the pull out so you can keep the seasonal storage in back is great. I will end up with 18" behind. Just a quick question, have you had any problems with the center section tipping or being unstable? I was thinking about putting a couple of cotter pins behind the rail. Thoughts?

  15. Thanks for not getting more in depth with the specs. Great idea nightmare to try and follow

  16. This tutorial has been fantastic! Have used to make my own version of eaves storage. Thanks so much x


Your comments make me smile! I love to hear what you think!
