What is Soffit?

A soffit is the horizontal underside of an architectural element, most commonly the area beneath a roof overhang or the enclosed boxed-down section above kitchen cabinets. In interior design, kitchen soffits — the boxy protrusions between the tops of cabinets and the ceiling — are a common renovation target.

Understanding Soffit

The word "soffit" comes from the Latin "suffixus," meaning "fastened beneath." Architecturally, soffits appear in multiple locations: under roof eaves (exterior soffits that ventilate attics), beneath staircase stringers, under archways, and most famously, above kitchen cabinets. Kitchen soffits were standard in homes built from the 1950s through the 1990s, serving both practical purposes — they concealed ductwork, plumbing, and electrical wiring that ran between the ceiling joists and the cabinet tops — and aesthetic ones, creating a finished look that eliminated the dust-collecting gap above short cabinets. As ceiling-height cabinets and open-to-the-ceiling kitchens became the design norm, soffits shifted from desirable to divisive, with many homeowners eager to remove them for a more spacious, modern look.

Soffit in Interior Design

Kitchen soffits present one of the most common design dilemmas in home renovation. Removing a soffit can dramatically open up a kitchen, allowing for taller cabinets, open shelving, or decorative displays above the cabinets. However, removal is not always straightforward — soffits often conceal HVAC ductwork, plumbing vents, or structural elements that cannot simply be relocated. When removal is not possible, designers have creative solutions: wrapping the soffit in the same material as the cabinets for a built-in look, adding trim and crown molding to make it look intentional, installing recessed lighting within the soffit, or using the soffit face for accent lighting that washes down onto the countertops. Modern new construction typically eliminates soffits by running mechanicals through the floor system instead.
