Elkhorn, Sun Valley, ID

Brian Poster started Poster Construction in 1997 with a clear sense of what good building looked like and a commitment to doing it that way every time. Nearly three decades later, Poster Construction, Sun Valley, ID is still family-owned, still based in the Wood River Valley, and still run according to the same principles. We’ve stayed small on purpose. A smaller team means tighter oversight, more consistent work, and relationships with our clients that result in better end results. Homeowners in Elkhorn who build with us know they’re working with people who live in this community, care about its character, and have a direct stake in the quality of every home we put our name on.

The most honest account of what it’s like to work with Poster Construction comes from the Elkhorn, Sun Valley, ID, homeowners and design partners who’ve been through the process themselves. They describe the experience in ways we couldn’t write on our own, talking about the communication, the follow-through, the way problems got handled, and what it felt like when the home was finally finished. We’ve been fortunate to work with clients who were willing to share those accounts, and we encourage you to read what they have to say.

Poster Construction offers a complete range of custom home construction services, so you have one experienced team accountable for every part of the work. We build new custom homes from the ground up, working in close coordination with you and your architect to make sure the design reflects how you want to live and the site you’re building on. Our remodel work reconfigures the spaces that don’t serve you the way they should, while our renovation projects bring older homes up to date in ways that honor what was already there. For clients with another team leading the project, our construction management and owner representation services add our oversight and accountability to the process from the start. Whatever your Elkhorn project looks like, it will always get the same level of care.

We’re deliberate about how we structure our custom home projects because consistency in the team is what produces consistency in the work. Every Poster Construction project is led by a dedicated supervisor and lead carpenter who see it through from beginning to end, with our in-house crew and a network of trade partners who’ve been working on our jobs for years. There’s no hand-off moment where a new crew arrives and gets brought up to speed. The people who start your Elkhorn, Sun Valley, ID, project are the people who finish it, and that continuity shows up in the quality of the work and in the experience of being a client throughout the process.

We have more Certified Green Professionals on our team than any other custom home builder in Idaho, and we’ve earned that by making sustainable building part of how we approach every project rather than treating it as a specialty service. Tighter building envelopes, well-designed mechanical systems, and materials selected for durability and indoor air quality are part of our standard approach. For homeowners in Elkhorn, the benefits show up as lower energy costs, more consistent temperatures through every season, and a home that stays in excellent condition over a long life. We build this way because it produces better homes, and better homes are what we’re here to build.

Building in the Wood River Valley means accounting for conditions that test a home in every season, and our team has spent years learning how to build homes that handle those conditions without showing the strain. We apply that knowledge throughout every Elkhorn project, from how we detail the foundation to how we approach the building envelope to the systems we specify and the finishes we recommend. All of those decisions matter, and they’re the difference between a home that functions as good as it looks for years and one that starts to fall short too soon. Our clients in Elkhorn, Sun Valley, ID, get homes that are built to perform from the first day and for every year after that.
