Need more space but love your Gig Harbor neighborhood? A room addition lets you expand your home on your existing lot — adding the bedrooms, bathrooms, or living space your family needs without the cost and disruption of moving.
Cascade Pro, Inc designs and builds custom room additions throughout Gig Harbor and Pierce County, handling everything from architectural design and engineering to permits, construction, and final inspection.
Every home and family is different. Here are the most common types of additions we build:
Add one or more bedrooms to accommodate a growing family, create a dedicated guest room, or build a primary suite with en-suite bathroom and walk-in closet. Bedroom additions are one of the most requested projects and add measurable value to your home.
Whether it’s a full bathroom, half bath, or expanding an existing small bathroom — adding a bathroom solves one of the most common homeowner complaints. We handle plumbing, tile, fixtures, ventilation, and all finishes.
Expand your home’s common areas with a new family room, sunroom, or great room. These additions create the open, comfortable living space modern families want without changing the rest of your floor plan.
When your lot doesn’t allow outward expansion, going up is the answer. A second-story addition can double your living space. We handle the structural engineering needed to support the new floor and tie the new level into your existing roofline.
Every room addition project follows a structured process to keep timelines tight and surprises to a minimum:
A room addition is a major investment that permanently changes your home — so it has to be done right. Cascade Pro brings the experience, licensing, and project management to deliver additions that feel like they’ve always been part of your house. Gig Harbor’s high home values, affluent homeowner base, and scenic waterfront setting make quality home improvements particularly worthwhile. Projects here command premium value in the resale market.
Room addition costs in Gig Harbor vary widely based on the size of the addition, complexity, foundation requirements, and finishes. A small single-room bump-out will cost significantly less than a multi-room or second-story addition.
Key factors that influence your project budget:
We provide detailed, line-item estimates after our initial property evaluation. You’ll know the full scope and cost before we break ground.
That depends on your lot size, zoning setback requirements, and lot coverage limits. During our consultation, we evaluate your property to determine the maximum addition size your lot can support within local building codes.
Absolutely — that’s a core part of our design process. We match the roofline, siding, trim, and architectural details so the addition looks like it was always part of the original home. Mismatched additions hurt resale value, so we take integration seriously.
Most room additions take 3 to 8 months from design through completion, depending on size and complexity. A single-room bump-out is faster than a multi-room or second-story addition. We’ll provide a realistic timeline during our initial assessment.
In most cases, yes. We plan the construction sequence to minimize disruption to your daily life. There will be some noise and activity, but we keep work areas contained and communicate the schedule so you know what to expect each week.
We handle the design and architectural work in-house, coordinating with licensed architects and structural engineers as required by your project. You don’t need to hire a separate architect — it’s all included in our full-service approach.
Adding permitted square footage to your home will likely increase your assessed value, which may affect property taxes. However, the increase in your home’s market value typically far exceeds the tax impact. We recommend consulting with a tax advisor for specifics.
Don’t let a lack of space push you out of the neighborhood you love. Cascade Pro, Inc builds custom room additions throughout Gig Harbor that give your family the space it needs while adding lasting value to your property.

Gig Harbor's unique character — a blend of charming waterfront village and upscale residential community — demands a contractor who appreciates both its aesthetic standards and practical building challenges. Homes here range from classic Northwest-style properties along the harbor to modern custom builds in master-planned communities like Gig Harbor North and Canterwood.
Because much of Gig Harbor falls under Pierce County jurisdiction rather than city limits, navigating the permitting process requires experience with both municipal and county codes. Our team has built strong relationships with local permitting offices and understands the specific requirements around shoreline setbacks, stormwater management, and the design review processes that apply to many Gig Harbor properties.
Whether your home is nestled in the Kopachuck area, overlooking Henderson Bay, or in one of the established neighborhoods near Purdy or Fox Island, we bring local knowledge that out-of-area contractors simply lack. Gig Harbor's wooded lots, sloped terrain, and marine climate all influence construction planning — and we factor all of it in from day one.
