I Built That!

DIY Angled Wall Shelf

How to build an angled shelf to fit your space | The Chelsea Project Blog | www.thechelseaproject.com

In honor of January,

the great clean, organize, and purge month,

I tried to purge…by using….not tossing…. as much scrap lumber as possible.

It’s been a month of building nice little ditties…

for all of the places that needed something special….

but had been on the lower end of the priority list.


So far, I’ve made oversized letters, a 48 inch long wall ledge, mitered picture frames,

and a bookcase (80″ W by 50″H… post coming in February).

……And…somehow….despite all of these projects…..

I’ve only used about half of the lumber.

I know…….right?

But, progress is progress…..

…..however slow…

or small.

I’ll happily take what I can get.


One day….I’ll park in the garage again.


But, for now,

I’m just so excited to explain how this awesome angled wall shelf is made.


Step 1:  End Pieces

First, determine the desired depth and angle of the wall shelf.  The end pieces will be completely flush against the wall on one side and angle out to support the shelf on the other side.  My end pieces measure 10 and 1/2 inches long on the side that is attached to the wall, 3 and 1/2 inches out from the wall, and 10 and 1/2 inches long on the slope side.


Step 2:  Internal Support Pieces

I used two different kinds of scrap lumber for my three pieces.   Any kind of lumber can be used as long as it can accommodate wood screws into the sides to create the internal frame and wood screws through the pieces to attach the frame to the wall.  Notice the wood is attached flush with the back of the end pieces.


To get the support piece flush in the front of the frame, attach the piece at an angle.


For a clean look, remember to counter-sink the screws.


Step 3:  Attach the Frame to the Wall

This shelf measures 27 and 3/4 inches long and both screws hit studs.  Two screws were attached in the top piece of wood, but none in the bottom piece.


The frame is centered and level.  So far, so good.


Step 4:    Attach Front Cover Piece

Suggest to use a thinner plywood for the front cover so that it is easy to glue and clamp into place.  I used a scrap piece of beadboard (1/4 inch thick) cut to cover end-to-end.  The wood glue is smeared on each end and across the bottom of the piece, then stuck to the frame.

Step 5:  Attach the Ledge

A piece of molding is glued on top of the plywood.  I held the piece in place until the glue began to set, then attached tape pulled tightly to hold the piece in place until the glue completely dried.  The ends are cut at a 45 degree angle.  The usable portion of the ledge measures one inch.

Step 6:  Attach the Bottom Piece

The bottom piece is glued and taped into place.


Step 7:  Finish with Wood Filler and Caulk

The outer portions of the shelf is then filled with either wood filler (which can be sanded) or caulk.  I used wood filler over the screws and caulk in the gaps between the wood pieces.


Step 8:  Paint 

I used two coats of primer-plus-paint in one…in a semi-gloss finish.  The beadboard is white because it is pre-primed so it covered very easily.

Step 9:  Add Accessories and Enjoy





Until next time,

Happy Building,

    The whole arrangement of the items on that wall is beautiful! I have my great-great-great grandmother’s Bible tucked away. You inspired me to display it.
