Floors and Ceilings

1. A composite material of marble, quartz, or glass chips set in cement and polished to a high luster
3. A secondary ceiling hung below the main structural ceiling, typically consisting of a metal grid and acoustic tiles.
4. A decorative finishing element used to transition between the wall and the ceiling.
6. The space between the structural ceiling and a dropped ceiling, used for air circulation, heating, and cooling systems.
9. (Luxury Vinyl Tile) A durable, modular flooring that mimics natural stone or wood but is made of PVC
10. Panels hung vertically from a ceiling to absorb sound waves and reduce echoes in large spaces
11. A layer of material (usually concrete or specialized mortar) leveled off to create a smooth surface for the final floor covering.
13. The underside of an architectural feature, such as a beam, arch, or a section of the ceiling that is lower than the rest (often used to hide ductwork).
14. A concrete floor that is poured directly onto the ground, common in modern residential and industrial builds.
15. A self-supporting arch above a floor, creating a high, sloping overhead surface (e.g., Barrel Vault, Cathedral Ceiling).

2. A floor system elevated above a solid substrate (like a concrete slab), creating a gap for cables, wiring, and mechanical services.
5. The structural layer (usually plywood or OSB) that rests on the joists and provides a solid base for the finish flooring.
6. Flooring composed of wooden blocks arranged in a geometric pattern, such as herringbone or chevron
7. A multi-level ceiling that looks like an upside-down tray, with the center section recessed higher than the perimeter.
8. Horizontal structural members used to support a floor or ceiling.
12. A series of sunken panels in the shape of a square, rectangle, or octagon in a ceiling, often used for decorative and acoustic purposes.
