The Carpenters Notch strikes again!

Geat craftsmanship starts with a strong foundation. Every cut, notch, and connection matters—because what you build is only as strong as the framework behind it.

The Art of Custom Cabinets

09/16/2026

Here’s 1 of 3 custom cabinets I am building completely on-site for this project.

Designed specifically for the space, built from scratch, and installed by 603 Decks owner David Merchant.

From the cabinet carcass to the inset doors and finish trim, every piece is being built to fit the home—not pulled off a shelf.

Rot happens. The repair is what matters. 🔨

This garage had more going on than just worn-out trim. Once everything was opened up, I repaired the rotted sill plate, properly flashed the openings, and rebuilt the exterior with PVC for a clean, low-maintenance finish.

✨ Custom Built-In Cabinet ✨

This homeowner wanted a custom storage solution that would fit perfectly between two windows while allowing room for an existing dresser underneath.

Built from birch plywood with poplar trim and finished with shaker-style doors, this project added both storage and character to the room while looking like an original feature of the home.

If you've got an empty wall, awkward nook, or need more storage, custom built-ins can completely transform a space.
