Custom Staircases in Boise, Idaho

Phillip Alexander Carpentry designs and builds custom staircases throughout Boise, Eagle, and the Treasure Valley, specializing in finish carpentry, structural stair framing, and architectural staircase construction. From floating stair systems and modern wood staircases to traditional architectural designs, each staircase is carefully built to complement the character and layout of the home.

Our work includes custom wood staircases, open-riser stair systems, detailed trim integration, custom railings, and structural stair framing for both remodels and new construction projects. Every project is built with careful attention to craftsmanship, proportion, durability, and architectural detail.

Whether integrating a staircase into a historic remodel or designing a focal-point staircase for a custom home, our goal is to create stair systems that function seamlessly while elevating the overall design of the home.
