Room Additions serving Coeur d'Alene and Kootenai County. Licensed, insured general contractor with 20+ years in Northern Idaho.
Adding square footage to an existing home in Coeur d'Alene means tying into an original structure that was built under different code requirements — possibly decades ago. Kootenai County has seen significant residential growth. Vandenberg Construction manages the permit process and subcontractor coordination so you don't have to navigate a busy building department yourself.
Room additions in Coeur d'Alene require matching the existing home’s structural elements, roofline, and mechanical systems — while meeting current Kootenai County building code. Vandenberg Construction handles every element of that process: structural review, design with 3D renderings, permits, and finish work that makes the addition look like it was always part of the original home.
The climate in Coeur d'Alene — 40+ inches of annual snowfall — means any addition also needs to be engineered for snow load. We don’t skip that calculation. Cost range for room additions: $100–$250 per sq ft depending on complexity.

Bedrooms, family rooms, sunrooms, mudrooms, garages, in-law suites, and ADUs. We also do second-story additions, which require careful structural evaluation of the existing foundation.
Yes — any structural addition requires a building permit plus electrical, plumbing, and mechanical permits depending on what’s included. We pull all permits and schedule inspections.
We start with 3D renderings so you can see the addition alongside the existing structure before work begins. Roofline matching, siding consistency, and material selection are all resolved in the design phase.
Most additions take 3–6 months from permit approval. Smaller additions like a sunroom can move faster; second-story additions take longer due to structural complexity.
Yes. Adding plumbing to an addition requires extending the drain and supply lines — we manage that through our licensed plumbing subcontractors and include it in the overall project scope.
