Types of Home Additions We Build

First-Floor Master Suite Additions

First-floor master suite additions create private, accessible living spaces with spacious bedrooms, walk-in closets, and en-suite bathrooms, offering comfort, convenience, and long-term functionality for homeowners planning for evolving lifestyle needs.

Sunrooms & Four-Season Rooms

Sunrooms and four-season rooms bring natural light indoors, creating relaxing spaces for entertaining or unwinding, designed with proper insulation, windows, and materials to ensure year-round comfort in West Michigan’s changing climate.

Second-Story Pop-Ups & Over-Garage Additions

Second-story pop-ups and over-garage additions maximize vertical space, adding bedrooms, offices, or living areas without expanding your home’s footprint, making them ideal for growing families needing additional functional square footage.

Kitchen Expansions & Dining Room Bump-Outs

Kitchen expansions and dining room bump-outs improve flow and usability, creating open, inviting spaces for cooking and gathering, while enhancing storage, layout efficiency, and overall home value through thoughtful design integration.

Real Reviews from West Michigan Homeowners

Laurel McCoy

Greg and his team did a great job on our deck project.  They had some wonderful ideas and caught my vision from the first day here.  Super easy to work with and very kind.

Matt Loan

Greg has a great team of professionals who pay close attention to all the details.  We had a large addition added to our house and continued to live in the home while the work was performed.  Originally, I was worried about how disruptive the construction would be while working from home.  It turned out to not be a problem and in fact my family and pets really enjoyed Greg and his team.
