Our Services

We focus on three things: more space, better flow, and Chicago-style durability.

Two-story brick home addition seamlessly blended onto existing Chicago house
01
Home Additions Chicago

We pour frost-depth footings, match existing brick coursing, and tie steel into existing foundation so your new family room feels original. R-21 insulation, 3/4-inch subfloor, and rooflines that shed Lake Michigan snow without ice dams. Every permit pulled, every beam engineered.

Room Additions Chicago

Need a main-floor office or a second-story primary suite? We cantilever LVL beams over existing walls, route new HVAC through joists, and land electrical on a 200-amp panel upgrade. Drywall hung with screw pattern per Chicago code, finishes matched to existing trim profiles.
