This extensive home addition project in Arlington Heights transformed a traditional split-level residence into a modern, spacious retreat. The renovation included removing the existing kitchen roof and constructing a full second-story addition featuring a master bedroom, office, walk-in closet, and bathroom. Downstairs, a new bathroom, redesigned kitchen ceiling, and full staircase upgrade added comfort and style. The exterior received a complete facelift with new Hardie board siding, energy-efficient windows, fresh stucco, and a brand-new roof. Finishing touches like the new porch, Juliet balcony, and upgraded garage brought a refined and cohesive look to the home’s design.
