Needed 34" wide cabinets (non standard width) to fit on either side of the window at our cabin, so decided to build my own.

Ordered both carcasses from Shelf Help for about $50 each.  These cabinets are a frameless design so I just put the Shelf Help Carcass together using a Kreg Jig, and then attached the doors with hinges.

Shelf Help Carcass

Here's the Shelf Help Carcasses I ordered.  The outside is put together with Kreg Jig Screws, the shelves are adjustable with shelf pins.

Finishing Details

We also built the Base Cabinets and the Island.  The paint color is Repose Gray by Sherwin Williams.  Knobs are Lombard.

The hinges for the doors are Full Overlay Concealed Hinges.  The door sizes are simply the opening size, cut in half width wise, then add 1/2" to both the height and width. I got all my hardware from D Lawless.
