General Information

What areas do you serve?

Poster Construction is based in Ketchum, Idaho. We proudly serve our neighbors across Blaine County, specifically focusing on Sun Valley, the Wood River Valley, and surrounding communities. Our team understands how to design and build for the unique architectural guidelines and environmental demands of the local mountain landscape.

What types of projects do you handle?

We handle premium residential builds of all sizes and scopes, including:

• Custom homes designed from the ground up
• Smart structural remodels tailored to how you live
• Home renovations that bring modern updates while respecting the original design
• Comprehensive construction management for complex estates

How long have you been in business?

We’ve been serving the Sun Valley area since 1997. Over our 29 years in business, we’ve honed a construction process built on open communication, meticulous discipline, and a 100% client satisfaction track record.

Are you licensed and insured?

Yes. Poster Construction is fully licensed, bonded, and insured in the state of Idaho. We hold high-limit liability and workers’ compensation coverage to provide maximum safety and protection for our clients, our crews, and your property.

Our Process

What are the steps to building a custom home with you?

We’ve spent decades perfecting a seamless process that takes you from concept to completion:

• Consultation: We sit down with you to listen to your ideas, goals, budget, and timeline.
• Design & Planning: We partner with you and your chosen design consultants to review plans for structural feasibility and localized build realities.
• Construction: Our experienced team begins construction, completing your custom home from laying the foundation to fine-tuning the final touches.
• Key Handover & Beyond: We walk through the finished structure together, verify every detail is flawless, and hand over the keys.

Do I need to bring my own architect, or do you provide design services?

We operate primarily as custom home builders and creative problem-solvers who work closely alongside your chosen architects and interior designers. If you don’t have a design team yet, we can connect you with premier local architects whose aesthetic matches your vision.

Services & Customization

Can you handle extensive luxury remodeling and renovations?

Absolutely. Remodels and renovations are core pillars of our business. Our team brings deep structural expertise to complicated renovations, allowing us to implement cutting-edge modern performance, plumbing, and structural updates while preserving the original character of historic or classic mountain homes.

How customizable are your custom homes?

Every project we build is 100% custom and tailored from the ground up to fit your lifestyle. We don’t utilize template floor plans or cookie-cutter materials. Every single detail is constructed to reflect your specific needs.

Budget, Pricing & Financing

How do you protect clients from going over budget?

We act as a tirelessly tenacious advocate for our clients. We require our extensive network of vetted local subcontractors to adhere strictly to clear, locked-in budgets. By providing detailed estimates during pre-construction rather than vague lump sums, we help minimize financial surprises mid-build.

Can you help evaluate a lot’s budget feasibility before construction?

Yes. Given the variable terrain, soil conditions, and hillside slopes in the Wood River Valley, we highly recommend involving us early. We can assess a potential property to help you understand utility connectivity, grading requirements, and foundation engineering factors before you finalize the site design.

Timeline & Project Management

How long does a typical custom home build take in Idaho?

The timeline varies depending on the architectural complexity and size of your home, but most custom builds average 12 to 24 months. Since winter weather in Sun Valley can impact outdoor construction, our team stages the schedule so the home’s shell is dried-in and enclosed before the heavy snow hits, keeping indoor progress moving smoothly all winter long.

Who will be managing my job site on a day-to-day basis?

Your home will be directly overseen by our expert management team. We don’t just manage from an office; we’re actively involved on the ground, supervising craftsmanship, enforcing schedules, and ensuring our strict standards are met daily.

Quality, Materials & Sustainability

What is your approach to eco-friendly and green building?

Poster Construction is a Certified Green Professional Builder. We believe a luxury mountain home should be as efficient as it is beautiful. We use advanced green building science to optimize insulation profiles, integrate high-efficiency mechanical systems, and implement sustainable practices that significantly lower your home’s energy footprint and stand up to the local weather.

How do you ensure your materials survive the mountain environment?

Sun Valley winters and high-altitude UV exposure require tough, high-performance materials. We select premium exterior siding, heavy-duty flashing membranes, and durable structural timbers engineered to withstand intense snow loads, deep freezes, and rapid temperature shifts without warping, cracking, or degrading.

Site & Construction Logistics

How do you choose the subcontractors who work on my home?

We only work with the finest specialty tradesmen in the region. Many of our local subcontractors have partnered with us for as many as 20 years. They understand our high aesthetic standards, share our commitment to excellence, and maintain a respectful, positive attitude on every job site.

How do you handle challenging mountain terrain or tight building sites?

Whether your lot faces a steep hill or is nestled in a dense residential neighborhood, we have the experience to handle complex staging logistics. We plan crane placements, soil retention systems, and material deliveries down to the exact hour to ensure construction doesn’t disrupt the local environment or surrounding neighbors.

Communication & Client Experience

How often will I hear from your team during construction?

We prioritize total transparency and open communication. You’ll receive regular, structured updates regarding budget tracking, schedule milestones, and physical progress. We’re always available to talk, answer questions, and adjust plans as the build progresses.

What happens if I want to make a design change mid-build?

As creative problem-solvers, we adapt seamlessly to changes. If you choose to modify a layout or material selection after construction begins, we’ll analyze the adjustment, calculate any budget or timeline impacts, and present a formal change order for your review so you can make an informed, confident decision.

Warranties, Aftercare, & Guarantees

What kind of support do you provide after you hand over the keys?

Our commitment to your home doesn’t end on move-in day. We stay by your side long after construction wraps up to help you learn your home’s systems. As many of our past clients have noted, we pride ourselves on continuing to be there for our homeowners as trusted local resources years down the line.

Do you provide a maintenance framework for seasonal home care?

Yes. Once your custom home project is completed, we guide you through every detail of your new property, from operating systems and warranties to maintenance schedules and care instructions, ensuring you feel completely confident and prepared.
