Finn Construction LLC

Finn Construction is a family-owned custom home building company serving Eastern Idaho and Western Wyoming, specializing in luxury custom homes, mountain retreats, modern farmhouses, and build-on-your-lot projects from $500K to $5 million. Led by owner and licensed general contractor Corey Finn and his wife Haley, Finn Construction has spent over 27 years building more than homes — they build legacies.

A Truly Personal Building Experience

What sets Finn Construction apart from larger firms is simple: when you hire them, you work directly with the Finn family from start to finish. Corey is on site regularly, working alongside his crew and personally overseeing every phase of construction. Haley brings a gift for design, helping clients navigate the countless decisions — flooring, cabinetry, stonework, lighting, and more — that make a house uniquely yours. There are no layers of project managers or sales reps standing between you and the people actually building your home.

Clients consistently rave about Corey's patience, transparency, and willingness to answer every question — especially first-time builders who need a contractor they can trust completely. No hidden costs. No surprises. Just honest, clear communication from day one.

Custom Home Building

Every Finn Construction home is designed and built around your lifestyle, your taste, and your vision. Whether you're dreaming of a sprawling mountain lodge near Yellowstone, a sleek modern farmhouse, or a high-end family home, Corey and his crew have the experience and craftsmanship to deliver. Build times typically run 8–14 months depending on size and complexity, with a detailed timeline provided before construction begins.

Build on Your Lot

Already own land in the Island Park area? Finn Construction specializes in build-on-your-lot projects, evaluating your site, reviewing utilities and access, and designing a home that fits your property perfectly. As true locals with deep knowledge of Eastern Idaho's land, climate, and building conditions, they bring insight that out-of-area builders simply can't match.

Personalized Design

Finn Construction can connect you with trusted architects and designers or work collaboratively with your existing design team. From the foundation to the finish work, every detail is selected by you — with expert guidance every step of the way.
