Home additions in Des Plaines, IL
Expanding your home in Des Plaines often means building upon the strong foundations of its mid-century housing stock. Many ranches and Cape Cods in neighborhoods like Lake Park or Devonshire, originally built with smaller footprints, are ideal candidates for additions that respect their architectural heritage while dramatically increasing living space. We frequently see projects transforming compact layouts by adding second stories or expanding rearward, extending kitchens, family rooms, or creating dedicated primary suites. These additions are designed to seamlessly integrate with the existing structure, both aesthetically and functionally, addressing the common desire for more open, versatile areas in homes from the 1950s and 60s.
What Des Plaines homeowners ask for
Des Plaines homeowners frequently request additions that create spacious primary suites, often integrating a walk-in closet and larger bathroom. Another common desire is for expanded family rooms or sunrooms, particularly at the rear of the home, to gain more light and direct access to outdoor living. Second-story additions are also popular for adding bedrooms or office space, allowing families to grow without moving.
About Des Plaines
Des Plaines is a postwar boom town, with ranches, Cape Cods, split-levels, and bi-levels filling in around a historic downtown. Remodeling here usually means opening up compartmentalized floor plans, rebuilding original bathrooms, or adding space.
Des Plaines' population nearly quadrupled between 1950 and 1970 as ranches, Cape Cods, split-levels, and bi-levels filled in around a downtown centered on Miner and Ellinwood Streets since the 1870s, while the Cumberland neighborhood mixes 1920s Tudors into that stock. Families are served by District 62 schools and Maine West, with Metra UP-NW stops downtown and at Cumberland.
The rapid growth between 1950 and 1970, filling in subdivisions with ranches, Cape Cods, split-levels, and bi-levels, often means dealing with smaller, more uniform lot sizes where setbacks are a key consideration for new construction. For these homes, additions must carefully integrate with existing roof lines and foundations, which are typically slab or crawl space for ranches and full basements for split-levels and bi-levels. The presence of 1920s Tudors in the Cumberland neighborhood, distinct from the mid-century stock, necessitates a different approach to tying into their unique architectural styles and foundation types. When planning additions, the Village of Des Plaines will review exterior changes to ensure compatibility with the established neighborhood character, particularly given the varying eras of housing stock around the downtown area.
Home additions in Des Plaines trigger detailed plan reviews for structural integrity, foundation work, and roof integration, alongside inspections at various stages, including framing, electrical, plumbing, and final. GS Construction & Remodeling manages the complete permit application process and coordinates all required inspections with the City of Des Plaines.

Greg and Patryk do amazing work and are incredible to work with! GS Construction completed two extensive bathroom renovations for us, including completely reconfiguring layouts and expanding one. Both bathrooms are absolutely beautiful, and they have significantly improved our family's quality of life in our home. Patryk and Greg are great communicators, take pride in their work, and have good attention to detail. Throughout the project, they really listened to us, took the time to understand what we wanted, kept progress going in a timely manner, and provided expert advice/suggestions and help on specific questions along the way. Every one of their team members did high-quality work. We couldn't be happier with the end result, and definitely will hire them for future renovations!
