A box is created against the wall , dropping down from the original ceiling height. Can be used for down lights to highlight art on a wall, or to tie in two rooms with differing ceiling heights.

Creating a feature in the middle of the room or dividing two areas, a •U• shaped bulkhead would be installed. Often used to mirror a central work unit in a kitchen, or bar area.

This bulkhead is built with two levels or steps. This design has the tendency for giving a room the feeling of height. It works well in areas where there are structural lintels.

A light trough is a gap created above the standard ceiling height in order to produce an superior effect on the area. Used to section or highlight areas in an open plan room.

Extruding barrels are generally used to disguise or conceal air conditioning ducting. With a barrel or vault ceiling there must be sufficient space between the roof void to house.

As with most European architecture, the ceiling dome creates the feeling of grandeur. The modern twist of a very classic ceiling is to place a light trough around the base of the dome.
