Mudroom Unit www.andrewharriswoodwork.com Page 1 of 25
Introduction This plan makes a unit which is 66 ¾ inches tall, 39 ½ inches wide and 18 ½ inches deep. It was custom made for some friends to fit the space available they had. On the unit I built I used solid planks for the sides rather than plywood. For ease of build though I have done these plans using plywood. For the 1 by 4 planks I used the more expensive Select pine boards except for the molding spacers which were No2 whitewood grade. I have tried to ensure all steps are covered in these plans but if you find any errors in the plans or have a question then please email me at info@andrewharriswoodwork.com to let me know. All my builds are made with pocket hole joinery. You will need a pocket hole jig tool such as a Kreg Pocket Hole Jig in order to build them. www.andrewharriswoodwork.com Page 2 of 25

Cut list Please read all instructions before cutting wood as shown below. I suggest some pieces are cut as you go to ensure a tight fit. To minimize the number of boards to use plan your cuts I have given details of which board I cut the piece from. If you find a more economical solution then please let me know.

Making the Base Part Step 1 Make the two Side frames Make the two side frames using the 18 and 10 ½ inch lengths of 1 by 3. www.andrewharriswoodwork.com Page 6 of 25
Step 2 Make the front and back frames Make the front and back frames using the 1 by 3 pieces shown. www.andrewharriswoodwork.com Page 7 of 25
Step 3 Join the sides together Join the four sides together as shown. You will need to put pocket holes on the inside of the side pieces facing outwards. They will be used for fixing the front and back frames to the sides. www.andrewharriswoodwork.com Page 8 of 25
Step 4 Add side inserts and back insert Add the ¾ inch plywood pieces to the insides of the sides and the back. The two side inserts are 18 by 15 ½ inches. The back piece is 35 inches by 18 inches. Fix with glue and 1 ¼ inch finishing nails or 1 ¼ inch wood screws. www.andrewharriswoodwork.com Page 9 of 25
Step 5 Add the base Add the base which is the ¾ inch plywood measuring 35 by 14 ¾ inches. Leave at least a 1 inch gap between the bottom of the base and the bottom edge of the cabinet. You will see why when we come to fit the molding trim. www.andrewharriswoodwork.com Page 10 of 25
Step 6 Add the base molding Drill holes through that bottom 1 inch of the sides left showing below the bottom edge of the shelf. Clamp the molding in place and fit the molding by screwing through frame into the molding. I tend to cut the front piece first and fit that and then cut the sides to measure and then cut the back rather than cut all pieces and expect them to be spot on. I also add some scrap blocks on the inside corners. I put pocket holes in one end of the scrap piece and screw that to the long trim piece so it is also tight with the short trim piece. I then screw through that into the base and then through the scrap piece back into the short trim piece. I find this helps keep the joint tight. An actual picture of it is shown below. You can see I also put some spacers using some scrap 1 by 4 I had between the two long trim pieces to stop them from moving if get kicked etc. www.andrewharriswoodwork.com Page 11 of 25

Step 7 Fit the middle divider Fit the middle divider piece of ¾ inch plywood measuring 16 ¼ by 14 ¾. This gives the seat some support in the middle. Drill pocket holes in each edge of the piece so it can be screwed to the bottom, front, back and top. You need only do them on one side of the piece. Step 8 Make the top Make the top from the 1 by 4 pieces shown www.andrewharriswoodwork.com Page 13 of 25
Step 9 Fitting the Top Drill pocket holes around the top of the base on the inside with the holes being drilled upwards. Place the top good side down and place the upturned base on it. Make sure there is an equal gap on the left and right hand sides. The back should be flush with the base leaving a ½ inch overhang on the front. www.andrewharriswoodwork.com Page 14 of 25
Step 10 Add internal trim I added 1 ½ inch trim ¼ inch thick to the inside of the base to hide the screws used to fix the side and back panels. I fixed this with ¾ inch nails and glue. If you add this then cut each piece to fit your build. www.andrewharriswoodwork.com Page 15 of 25
Making the Top Piece Step 11 Make the back frame Make the back frame from the 1 by 4 pieces shown. Put the pocket holes on the back side. www.andrewharriswoodwork.com Page 16 of 25
Step 12 Add back panel Fit the ¾ inch plywood back panel to the frame (so it is attached to the side with the pocket holes) and fix with 1 ¼ inch wood screws and glue. Make sure you don t put the screws where you want the hooks to go on the reverse side!! www.andrewharriswoodwork.com Page 17 of 25
Step 13 Add the sides and top Add the sides which are the ¾ inch ply pieces measuring 44 inches by 11 inches and the top measuring 35 ½ by 11 inches. Drill pocket holes on the outside pieces as they will be hidden by the trim. Put the pocket holes on the top side of the top piece so they are hidden. www.andrewharriswoodwork.com Page 18 of 25
Step 14 Add the top molding Add the top molding. I drilled through the very top of the sides (which would then hide with some trim) to screw the molding to the sides and back with 1 ¼ inch wood screws. I then added corner blocks as with the base to pull the joints tight and stop them moving. For the front edge drill pocket holes in the plywood and screw to the front trim using 1 ¼ inch pocket hole screws. www.andrewharriswoodwork.com Page 19 of 25
Step 15 Add bracing for molding I added some scrap 1 by 4s as shown to 1) brace the top and back sides of the molding and 2) to have something to fix a sheet of ¼ inch plywood to just to finish off the top. www.andrewharriswoodwork.com Page 20 of 25
Step 16 Add ¼ inch ply to top Add a piece of 37 by 12 ½ inch ¼ inch thick plywood just to finish the top. www.andrewharriswoodwork.com Page 21 of 25
Step 17 fix the top to the base Drill holes in the bottom edge of the sides of the top. You will then fix the top to the base using 1 1/4 Inch pocket hole screws. I used 3 on each side and about 8 on the back to ensure fixed well. I also used glue. The holes on the side will be hidden by trim. www.andrewharriswoodwork.com Page 22 of 25
Step 18 Add the side trim Add the side trim. I used 3.5 inch by 0.25 inch trim which is wide enough so you don t have to fill and sand the pocket holes. Fix with ¾ inch finishing nails and glue. www.andrewharriswoodwork.com Page 23 of 25
Step 19 Add the front trim Add the two 42.5 inch by 1.5 inch pieces of trim to the front to hide the edge of the plywood. www.andrewharriswoodwork.com Page 24 of 25
Step 18 Add the internal trim To cover the screws fixing the top molding to the sides and back add 1 1.2 inch trim ¼ inch thick to the inside of the cabinet. Step 19 Finish Finish in your choice of stain or paint. Step 20 Add Coat hooks Add coat hooks of your choice www.andrewharriswoodwork.com Page 25 of 25
