Room Additions in Northern Idaho

Add the space your family needs without moving—master suites, family rooms, sunrooms, and more.

Expert Room Additions Across the Idaho Panhandle

Seamless additions that match your existing home. Structural work, framing, insulation, and finish carpentry all handled in-house. Whether you're in St. Maries, Coeur d'Alene, Kellogg, or anywhere across the Idaho Panhandle, Vandenberg Construction brings over 20 years of general contracting experience to every project.

Ryan Vandenberg is a finish carpenter by trade. That background means the quality standard on every project isn't set by a project manager who's never swung a hammer — it's set by someone who built his career on precision and detail. That shows in how every Vandenberg project is finished.

The Vandenberg Construction Difference

Quality Over Quantity

Ryan Vandenberg founded this company specifically because the industry had let quantity take over at the expense of craftsmanship. Every project we take, we finish right.

3D Design Before We Build

We offer a full design process including 3D renderings before a nail is driven. You see your finished project before we start—no surprises, no guesswork.

Upfront, Honest Pricing

We’re straightforward about what things cost and we never overbid for our own gain. Our quote is our quote.

Finish Carpentry Roots

Ryan started as a finish carpenter. That precision shows in every trim detail, built-in, and cabinet installation we deliver.

Subcontractors We Stand Behind

We hold every subcontractor to the same standard we hold ourselves. If it doesn’t meet our bar, it doesn’t leave our job site.

Owner Involvement Start to Finish

Ryan is involved from your initial inquiry through project completion. You’re not handed off to a project manager who’s never held a tape measure.

Our Room Additions Process

Initial Consultation

We start with a consultation to understand your goals, timeline, and budget. No sales pressure — just an honest conversation about your project.

3D Design & Scope Development

For most projects, we develop a 3D rendering so you can visualize the finished result before we break ground. You approve the design before a single nail is driven.

Upfront Quote

You receive a detailed, line-item quote. No vague estimates, no overbidding, no scope creep without a conversation. Our quote is our quote.

Construction

Ryan coordinates all subcontractors and is on-site regularly throughout construction. Quality is checked at every phase — not just at the final walkthrough.

Final Walkthrough & Completion

We walk through the finished project together. If anything isn't right, we fix it before we consider the job complete.

Matching existing construction is a precision craft, and finish carpentry is Ryan Vandenberg’s background. We match rooflines, siding, trim, and interior finishes to the existing home. When the addition is done, it should be difficult to tell where the original structure ends.
Yes. All room additions require building permits in Idaho, plus mechanical, electrical, and plumbing permits as applicable. Vandenberg Construction manages the permitting process and coordinates all required inspections.
A standard room addition (master suite or family room addition) typically takes 3–6 months from permit approval through completion. Timeline depends on scope, finish level, and the exterior construction window. Projects that start in spring and have exterior work wrapped by fall typically move fastest.
Yes. Vertical additions (second-story builds) are an option when the lot doesn’t allow outward expansion, or when maintaining yard space is a priority. Second-story additions require a structural engineering review to verify the existing foundation and framing can support the load. Vandenberg handles this coordination.
