How to Start Your DIY Outdoor Kitchen

Tools, Setup & First Course (Unity Series)

Tags: | | |

Terry breaks down the “book learning” of the Cornerstone System, explaining the metric-based logic of the small, medium, and large wedge blocks. This video transitions from site organization—sorting your pallets by block size—to the physical execution of striking a back-wall chalk line and using a 4ft level to verify structural integrity before a single bead of glue is dropped.

The success of an outdoor kitchen build is determined in the first hour. This foundational guide covers the critical preparation steps for the Unity Series, from organizing your job site to mastering the “Center-Out” layout technique. By focusing on a perfectly square and level first course, you ensure that every subsequent layer of your modular grill island fits with precision engineering.

Project Duration: Half Day

Project Difficulty: Beginner

You Will Need:

  • Unity Series Kitchen Kit: Includes precision-cut blocks and adhesive.
  • 4ft Level with Plumb Vial: Crucial for the base course and vertical alignment.
  • Dead Blow Hammer: To securely abut blocks without damaging the masonry.
  • Standard Caulking Gun: For applying the included adhesive.
  • 16 to 24-inch Square: To verify the foundation is perfectly square.
  • Electronic Leaf Blower or Brush: Essential for removing dust and debris from blocks for a permanent bond.
  • Custom Countertops: Optional (Honed limestone slabs available; required if you are not sourcing your own).
  • Tape Measure & Gloves: Standard safety and layout tools.

Pro Tip:

The Honed Finish Advantage: If you source your own custom countertops, avoid highly polished surfaces like mirrored granite. Outdoor kitchens are exposed to grit and weather; a polished finish will show every fine scratch from a beer bottle or serving tray. We use a honed finish specifically because it maintains a premium look while hiding the wear and tear of a working outdoor space.

Preparation: The “Clean Workspace” Rule

A permanent bond depends on a clean surface. Terry demonstrates why a leaf blower is a mandatory tool for the modern mason; by blowing off the pallets and each course after it is laid, you ensure the adhesive bonds to the stone, not the dust.

Organizing Your Job Site

To keep the build moving fast, site organization is key.

  • Pallet Placement: Get your blocks as close to the build area as possible.

  • The Fittings Pallet: Identify the specially marked palette containing your unique structural pieces and keep it immediately accessible.

  • Color Blending: Pull blocks from multiple pallets simultaneously to ensure a natural, varied color distribution throughout your kitchen.

The First Course: The Metric Logic

The Unity Series is built on a modular wedge system (nominally 4″, 8″, and 12″). Understanding how a small and medium wedge combine to equal a full wedge allows you to troubleshoot layout issues quickly.

  • The Center-Out Method: If you aren’t building from a corner, Terry shows how to use a center line and guide blocks to ensure the kitchen is perfectly balanced.

  • Squaring without a Large Square: If your shop square is too small for the project, learn the straight-edge extension trick using your 4ft level to verify the 90-degree corners of your foundation.
