The Northstar Construction Home Addition Process

At Northstar Construction, we treat every addition project like a complete home transformation. Our step-by-step process ensures your new space is strong, beautiful, and built to code.

On-Site Consultation and Planning

Every project begins with a conversation about your goals, layout ideas, and how you want the new space to feel. We evaluate your existing structure, foundation, and rooflines to make sure the new addition blends naturally and supports long-term stability.

Design and Blueprint Development

Our design team creates plans that capture your vision while meeting building standards. You’ll see how your addition fits within your home’s layout, including details like lighting, window placement, and flow.

Demolition and Site Prep

If the project involves expanding outward or upward, we carefully remove sections of exterior walls or roofing while maintaining your home’s integrity. Site preparation includes grading, foundation work, and framing for a solid start.

Framing and Construction

Once the foundation is ready, we frame the walls, install roofing, and complete structural work. Our crew uses high-quality materials to ensure durability, weather resistance, and precise alignment.

Interior Finishes

We handle drywall, insulation, trim, flooring, and paint to give your new space a polished look. Everything from lighting and fixtures to finishes is handled in-house for consistency and quality.

Final Inspection and Walkthrough

Before the job wraps up, we inspect every detail to ensure everything meets code and exceeds your expectations. You’ll get a clean, finished space that’s ready to use immediately.

Do Room Additions Add Value?

Absolutely, room additions are one of the most effective ways to increase both the livable space and market value of your home. When planned and built correctly, an addition feels like a natural part of your property while adding major functionality and appeal for future buyers.

1. Increased Square Footage

Extra space always translates into higher value. Whether it’s a larger family room, an extra bedroom, or a home office, more square footage typically boosts your home’s appraisal price and overall resale potential.

2. Enhanced Functionality

A well-designed addition makes your home more comfortable and adaptable. Adding a sunroom, master suite, or in-law suite provides flexibility for growing families or changing lifestyles, which is something buyers look for.

3. Modern Upgrades

Room additions often include updated wiring, insulation, and energy-efficient windows. These improvements lower utility costs and make your home more appealing to modern buyers who value comfort and efficiency.

4. Improved Curb Appeal

When an addition blends seamlessly with your existing design, it enhances the overall appearance of your home. The combination of added space and upgraded exterior features can make your property stand out in the neighborhood.

5. Long-Term Return on Investment

According to national remodeling data, most homeowners recover a significant portion of their investment when selling. Even if you’re not planning to move soon, you’ll still enjoy the everyday benefits of a larger, more functional home.

At Northstar Construction, every home addition is designed to deliver lasting value, both financially and personally. From concept to completion, we make sure your new space complements your home, improves comfort, and strengthens your property’s future worth.

Popular Types of Home Additions

At Northstar Construction, we design and build a wide range of home additions that give homeowners in Moline more space, comfort, and value. Here are the five most popular types of additions we build across the Quad Cities:

1. Room Additions

Room additions are a simple and effective way to expand your home. Whether you need an extra bedroom, home office, or family room, these additions create more livable space while blending naturally with your existing layout.

2. Second-Story Additions

When there’s no room to build outward, building upward is the next best choice. A second-story addition can double your square footage, add new bedrooms or bathrooms, and completely transform your home’s design.

3. Master Suite Additions

A master suite addition provides a private retreat that enhances both comfort and value. We can design your new space with features like a walk-in closet, spa-style bathroom, and sitting area tailored to your needs.

4. Kitchen Expansions

A larger kitchen changes the way you live and entertain. Expanding your kitchen allows for more counter space, modern appliances, and open layouts that make daily life easier and more enjoyable.

5. In-Law Suites and Guest Additions

Adding an in-law suite or guest space gives loved ones comfort and privacy while keeping everyone close. These additions often include a bedroom, bath, and small kitchenette, perfect for extended family or visitors.
