We build room additions that integrate seamlessly into your home's existing floor plan and exterior profile.
Every room addition includes proper insulation, electrical rough-in, and all city-required permits. We match exterior siding, roofing, and trim so the addition looks like it was always part of the original structure.

Our team pours the concrete slab, erects the framing, installs overhead doors, and completes all electrical work required for lighting and power outlets. We coordinate all required city permits and ensure the structure meets current Chicago zoning and building code requirements.
