For brick buildings with a parapet wall and flat roof a brick cornice is generally the most appropriate unless one of terra cotta can be afforded. A brick cornice is certainly to be preferred to one of galvanized iron or wood, as it is more durable and will not require painting, besides being a more appropriate use of material.

In cornices where considerable projection is desired it is almost always safe to adopt some corbeled treatment, building the corbels up by slightly projecting each course. Dentil courses in cornices and string courses are also very effective and easy to lay.
