How to Build a Hidden Door in a Wall

We have all been a fan of secret hideouts when we were kids. Do secret pathways or hideouts still excite you? If you have not grown out of the idea of a hidden door that leads to a secret room, then we will share some amazing techniques with you regarding how to build a hidden door in a wall at your place. Hidden doors do not have to be something you only see in fantasy; and we are here to teach you exactly how to change your childhood wish into reality.

It is better to look into a few things before you actually start the construction of your hidden door.

1. Functionality:

If you want your hidden door to be functional then bookshelves are a great way to create a truly functional hidden door. Just imagine your bookshelf opens up into another room by a push of a hidden lever in your bookshelf. It is better to make the bookshelf in such a way that it blends in with the rest of your furniture.

2. Location:

You probably already know if there is somewhere in your house appropriate for a hidden door. If not then consider what room do you want the hidden door in, and what room do you want it to lead to? Before you decide this make sure that where you are installing the hidden door does not cause issues when it comes to mobility in that area.

3. Creativity:

It is your hidden door you can be as much creative as you want. You could attach an end table or anything you like. Furthermore, with the help of technology, you could have a motion-activated opener or a remote opener for your bookshelf.

As we mentioned you can be as creative as you want. Since bookshelves are a great way to create a truly functional hidden door, therefore, we will be using the same idea to create the hidden door using solid wood edge-glued panels.

So let’s begin our hidden door adventure!

For the bookshelf, you will need two sheets of 1/4″ sanded plywood and 6 panels of 3/4 x 15 1/4 x 96 laminated pine project board together with a few lengths of 2×4 construction lumber. The rest of the tools would be the same required to build an ordinary bookshelf.

Rip one board 7 1/2″ wide out of each piece of shelving and trim to 83 7/16″ long. Cut a rabbet to accommodate the 1/4″ plywood for the back, make it about 3/8″ wide so fixing it to the back is easy. Now rip one board 7 1/4″ wide out of each leftover piece. Trim to 83 7/16″ long. Rip all of these into boards 7 1/4″ wide. From these six longboards, cut eighteen pieces 28 1/4″ long. Twelve of these are adjustable shelves, and will probably need to be shortened slightly so that they fit easily.

Rip a strip 7-7/8″ wide, and cut to 59-1/2″ long. Rip a second strip 3-9/16″ wide, and cut to 59-1/2″ long for the back. Rip another strip 2-3/4″ wide, and cut to 61″ long, for the front. From the 2 3/4″ offcuts, cut another two pieces 8 5/8″ long, for left and right.

Here is the list of pieces you will further need:

Two 28 1/4″ × 1 1/2″ × 3/4″. For the right middle and left middle.

Four 28 1/4″ × 2 3/8″ × 3/4″. For top right, top left, bottom right, and bottom left.

Two 83 7/16″ × 1 3/16″ × 3/4″. For back left and back right.

One 83 7/16″ × 2 3/8″ × 3/4″. For middle.

Four 5 29/32″ × 2 3/8″ × 3/4″. For the top right side, top left side, bottom right side, and bottom left side.

Two 83 7/16″ × 1 3/16″ × 1 1/2″. Cut a rabbet 7/16 × 3/4″ out such that the two arms of the leftover L-shape are 3/4″. For the front left and front right.

Two pieces 83 7/16″ × 29 3/8″ because you need an entire sheet for each shelf back.

The outside of each bookcase is made of five pieces of wood. Before attaching the short pieces, you need to cut out pieces to accommodate the hardware. Glued and screw these small pieces, since the screw heads are not going to show.

There are three L-shaped fixed shelves for each half of the door. Join these using pocket screws, which require the use of a jig and a specially shaped drill bit. Pocket screws pull the two pieces of wood together very tightly, and you can do the joinery without the need for clamps. You should end up with six L-shaped shelves, two with 1  1/2″ deep front pieces for the middle and four with 2 3/8″ deep pieces for each end.

Use pocket screws and wood glue to join the sides and three horizontal members. Just make sure that the case remains square – you may use of a square of plywood to measure ninety-degree angles and diagonal braces to hold the shelves aligned while the glue dried.

For the plywood back cut the 1/4″ plywood sheets to 83 7/16″ × 29 3/8″, and glue and nail to the back of the bookcase.

Valance can be entirely built with pocket screws. Install reinforcing brackets on the top, and the guide track underneath.

For the lower track, you need a length of hardwood. Cut a piece of oak 61″ long and nominally 1×4 (but actually only 3/4″ × 3 1/2″). Carve 3/16″ deep dado using the table saw, drill a hole to accommodate the pivot hinge, and shape the edges.

Time to install the bookshelf. Attach the pivot hardware, join the two sides of the door with a piano hinge, stand the door up, put the valance on top with 1/4″ spacers, mark the drill hole locations for the lag bolts, remove the valance, drill the holes, then replace the valance and lag bolt it into place. Your bookcase should now operate as intended.

Cover the valance with a sheet of 1/4″ plywood. By doing so you have now created a large space that is perfect for hiding stuff in or maybe yourself hehe.
