A frieze is a common design element in classic architecture. It is a long, thin area between the cornice and the column capitals and is covered in sculptural elements.

French doors are a pair of wooden doors with large glass areas that extend most of the height. The glass on the doors are typically divided into smaller panels. French doors are typically in pairs (but not always) and they are often used to separate a back entry or other interior condition, since they do not offer much privacy as a front door.

A free plan, or “open plan” as it is sometimes called, is when a floor plan is carefully designed to limit the need for load-bearing walls. The major load is carried by the outer walls and columns carry the rest. The open plan allows for more freedom since there are no extra walls to limit design.

The flying buttress is a specific kind of buttress that is built on a separate pier and connects to the wall that it supports. The term flying describes the fact that it is not built against the wall it supports—as in a traditional buttress as defined earlier in this list—and instead connects using an arch that “flies” from the pier to the connecting wall.

A floor plan is one of the most critical forms of architectural drawing. It is the representation of a work from above that cuts through walls to show the clearest representation of all spaces. Many floor plans are labeled to best show the functions of each space. Other common details include the swinging directions of doors, entry, vertical circulation, wall thicknesses that designate material, window cut outs, and furniture.

In architecture, fenestration is the combination of windows and doors on a façade and how they are arranged on a building. While these openings serve an obvious functional purpose, there is a lot of room for design in the fenestration of a building.

In architecture, a façade is a face of the building. Façades are also sometimes referred to as an elevation, a concept described earlier on this list.

Fabrication refers to the way things are put together in architecture. Contemporary methods of fabrication include 3D printing and the use of robotics, but the term refers to any way of building of a physical object.

A method, also called hot stamping, of melting foil or pre-dried ink to a design to create a metallic finish.
