Streamline Renovates designs and builds full-scale home additions that expand your square footage without compromising the character of your existing home. From primary suite additions with spa-style bathrooms and walk-in closets to expanded family rooms, second-story pop-ups, and in-law suites, our team handles structural engineering, permitting, framing, roofing, electrical, HVAC, and finish carpentry from start to finish. Every addition is custom-designed to match your home's rooflines, siding, trim profiles, and interior flow so the new space feels original — never bolted on.
Bump-Out Additions
A bump-out addition is one of the most cost-effective ways to gain critical square footage without the expense of a full addition or foundation. Streamline Renovates builds custom kitchen bump-outs for larger islands and breakfast nooks, bathroom bump-outs for double vanities and soaking tubs, mudroom and entry bump-outs, and dining room extensions — typically two to fifteen feet of new living space tied seamlessly into your existing structure. Our team manages cantilever engineering, exterior siding and roofing matches, and interior finishes so the addition looks intentional inside and out.
Sunrooms & Mudroom Additions
Streamline Renovates builds four-season sunrooms, three-season porches, screened-in additions, and hardworking mudrooms engineered for Midwest winters and humid summers. Our sunrooms feature insulated walls, energy-efficient windows, in-floor heating options, and HVAC integration so you can use the space year-round, while our custom mudrooms deliver built-in cubbies, benches, lockers, tile flooring, and dog-wash stations tailored to how your family actually lives. Every project is fully permitted, insulated to code, and finished with the same craftsmanship you'd expect from the rest of your home.
Additions that disappear into your existing home.
Matt personally walks every property to study rooflines, siding, trim profiles, and window placement before a single drawing is made. The result: additions in Glen Ellyn, Elmhurst, Naperville, Wheaton and other western suburb cities, that look original and not an add on.
