Expanding Your Home with Purpose and Precision

At Craftside Construction, we specialize in creating seamless home additions that give Maple Valley homeowners more space to live, work, and relax—without having to move. Whether you’re growing your family, adding a new suite, or simply wanting more room to enjoy your home, our team designs and builds additions that blend beautifully with your existing structure. We handle everything from concept to completion, ensuring your new space feels like a natural extension of your home.

Designing Additions That Match Your Vision

Every home addition begins with a vision. Our design and construction teams collaborate with you to understand your goals, lifestyle, and how the new space will function day-to-day. From the very first sketch, we focus on maintaining architectural harmony, structural integrity, and aesthetic consistency.

Room Additions and Expansions

We build all types of home additions—from extra bedrooms and expanded living areas to new offices and media rooms. Each project is customized to match your existing layout while adding value and comfort. Whether you need a quiet retreat, a spacious family area, or a dedicated workspace, we tailor every element to your needs.

Second-Story Additions

If you love your location but need significantly more space, a second-story addition may be the perfect solution. Craftside Construction manages every stage of the process—from reinforcing the existing structure to framing, roofing, and interior finishing. We ensure your new level integrates seamlessly, both structurally and visually, with the rest of your home.

ADUs and In-Law Suites for Flexible Living

Accessory Dwelling Units (ADUs) and in-law suites are among the most popular additions in Maple Valley, Issaquah, Bellevue, and the greater Seattle area today. They offer flexibility for multi-generational living, rental opportunities, or private guest accommodations.

Custom-Designed for Comfort and Functionality

Our team designs ADUs that maximize available space while maintaining privacy and independence. We integrate full kitchens, bathrooms, and living areas into compact yet stylish layouts. Every ADU project is planned for long-term usability and local code compliance.

Detached and Attached ADU Options

We handle both attached and detached ADUs, depending on your lot size and vision. Whether you prefer a private backyard cottage or an integrated apartment above your garage, Craftside Construction ensures every build meets Maple Valley’s zoning and permitting requirements.

Seamless Integration with Existing Structures

A successful home addition should never look like an afterthought. Our builders carefully match your home’s existing architecture, roofline, and materials to create a unified, cohesive look. We take extra care in blending exterior finishes, trim, and siding so the addition enhances your home’s character rather than altering it.

Interior Continuity and Design Flow

Inside, we align flooring, wall textures, lighting, and finishes to maintain a continuous feel throughout your home. Our attention to detail ensures that your new space connects naturally with the rest of your interior—both functionally and aesthetically.

Full-Service Project Management

From the first consultation to the final walkthrough, Craftside Construction manages every aspect of your home addition. Our team oversees architectural design, permitting, engineering, construction, and inspections, keeping your project on schedule and within budget.

Coordination and Communication

We believe clear communication is key to a successful build. You’ll have a dedicated project manager who provides updates, answers questions, and ensures your goals are met at each phase. This hands-on approach allows homeowners to stay informed and confident throughout the process.
