🛠️ TOOLS & MATERIALS
“(2) 4’x8′ 3/4″ Plywood
(1) 4’x8′ 1/4″ Plywood
(1) 4’x8′ 3/4″ Plywood (for top)
(7) 22″ Drawer Slides
(2 pair) 110 degree euro hinges
(7) drawer/door pulls
… 1-1/4″ pocket screws
… Water based Poly”
⚙️ STEP-BY-STEP INSTRUCTIONS
Step 1: Assemble the base cabinet carcass
“I started off the project, by breaking down two plywood sheets into smaller sizes for easier handling. … The sides of the storage cabinet are connected with horizontal supports on the top and bottom.”
“All the horizontal supports will be attached to the sides using pocket screws … laid one side down … attaching the pieces vertically … lower supports as well as the toe kick plate which is actually a structural piece.”
Step 2: Build the cabinet drawers
“I cut the base cabinet drawers to size based on the dividers. … took them to the tablesaw to cut grooves for the bottom panel. … pull out trays go together really easily. … assembled them upside down to make sure that all the grooves were aligned.”
“Since the base cabinet drawers will have a false front I used pocket holes on the front and back pieces for joinery. … All the trays and drawers get a ¼” bottom panel. … Each panel then gets screwed into the drawer back with some pan head screws.”
Step 3: Install the cabinet drawers
“Each side of the base cabinet will get two pull out trays, one on the bottom and one near the middle. I shimmed up the bottom slides with ¼” plywood and gave them an ⅛” setback. Then I used pilot holes and screws to secure each drawer slide to the base cabinet.”
“I used the plywood spacers to support the tray and pulled out the slide arms and secured them to the sides. … After attaching a front and center screw I removed the tray and installed a third screw in the back.”
Step 4: Add concealed hinge doors & drawer fronts
“I’m using concealed hinges to mount the doors to the shop cabinet. … You line up the jig on the base cabinet door then attach your drill … and drill out the hole for the cup.”
“Then install cabinet false drawer fronts and hardware.”
Step 5: Install countertop (optional)
“I removed the pull out trays and secured the top to the base cabinet with screws from below and the project was done.”
💡 TIPS & NOTES
- Use a pocket hole jig—makes assembly fast and strong
- Shim and use spacers so drawer slides sit level
- Use concealed hinge jig for clean, professional doors
- Spots like drawer bottoms hide raw plywood edges when routed or chamfered

What are the different types of balcony support brackets?
Types of Balcony Support Brackets
Balcony support brackets come in a variety of shapes and sizes. The most common are:
Cylindrical – These are round in shape and attach to the floor or wall. They may be made of wood or metal, depending on the material used in the construction of your home.
Corner – These brackets are L-shaped and attach to both sides of your balcony. They can be made from metal or wood, depending on your preference and budget. If you’re looking for a more decorative look, choose wooden corner brackets as they come in many colors and designs.
Floor – These brackets are placed underneath the floor joists above your balcony, which means that they don’t need to be attached to any other part of your home outside of its foundation. As such, they can be installed without any tools or special skills required to do so!
Balcony support beams are a common type of support used in balcony construction. A beam is a long, horizontal structural member that supports a load and transfers it to the structure below. The beam is usually made from wood or steel and may be made up of several smaller components fitted together.
Balcony support beams are typically made of steel or wood. Steel beams are more common in commercial buildings, while wooden beams are more common in residential buildings. In both cases, the beams are installed using brackets and posts.
The main purpose of balcony support beams is to help distribute the weight of the floor above down through the walls and foundations below. This prevents any damage to those structures if too much weight were placed on top of them.
A typical balcony beam consists of an upper flange and lower flange connected by web members (or I-beams). The flanges can be made from either metal or wood, depending on what material has been specified by your architect or builder for your project.
