At Josel Construction & Development, building a home in Sun Valley or the Wood River Valley is more than construction, it’s a personal journey. Led by Jack and Rachel Josel, we specialize in custom homes, luxury home construction, and high-end residential remodels across Idaho.
As a trusted Sun Valley general contractor, we offer full-service solutions—from pre-construction services agreements (PSA) to final walkthroughs. Whether you’re planning a mountain home remodel, exploring cost plus or GMP construction, or seeking an experienced architectural home builder, we deliver with integrity, precision, and lasting value.
We’re not the cheapest – we’re the best at what we do. Every project is tailored to your lifestyle, goals, and vision.
With a background rooted in structural expertise and high-performance project management, Jack brings deep technical knowledge and a refined builder’s mindset to each home. Rachel’s eye for design and client care brings warmth and sophistication to the entire process.
Together, they form a dynamic team that combines craftsmanship with connection, ensuring every client is fully supported through each phase of construction.
At Josel Construction & Development, we don’t just build homes—we build trust and deliver precision. As a leading custom home builder in the Wood River Valley and Sun Valley general contractor, we’re known for quality craftsmanship, clear communication, and on-time project delivery.
Our hands-on approach ensures that every luxury home construction, high-end remodel, or mountain home renovation is managed with expert oversight and deep respect for your vision, budget, and timeline—whether it’s cost plus or GMP construction.
We specialize in custom new home construction and high-end residential remodels and additions. Every project is uniquely tailored to meet the individual needs, style, and vision of our clients.
Our PSA ensures that every project begins with proper planning, budgeting, and coordination. It provides a framework to develop your design, estimate costs, and assemble your team before construction begins—saving time, reducing surprises, and adding value.
We offer Cost-Plus and Guaranteed Maximum Price (GMP) structures to give clients flexible and transparent pricing options. We’ll help you determine which method best fits your project goals and risk tolerance.
Start by filling out our Inquiry Form on the Contact page. We’ll schedule a face-to-face meeting to discuss your goals, timeline, and the vision for your home. From there, we’ll guide you through our PSA process and project development.
A Cost+ contract charges you the actual cost of construction plus a builder’s fee, offering full transparency and flexibility throughout the project. A GMP (Guaranteed Maximum Price) contract sets a cap on total costs, protecting you from overages while still allowing for shared savings if the project finishes under budget. Cost+ is ideal for evolving custom builds, while GMP offers more financial certainty upfront. We’ll help you choose the right fit based on your goals and comfort level.
While our primary focus is in the Wood River Valley and surrounding areas, we occasionally take on select projects in neighboring markets based on scope and alignment. Please reach out to see if your project is a fit.
We are not a volume builder. Our team is led directly by the owner and his wife, ensuring a high-touch, boutique experience. We prioritize quality over quantity and believe in personalized service, transparency, and superior craftsmanship.
Yes. We offer site maintenance and ongoing support after project completion. Whether it’s a minor update or seasonal maintenance, we’re here to ensure your home continues to perform and impress for years to come.
We offer a collaborative experience. You’ll be involved in key decisions while we handle the technical execution and project management. Our goal is to make the process seamless and rewarding.
