Veranda

A veranda or verandah is a roofed, open-air hallway or porch, attached to the outside of a building. A veranda is often partly enclosed by a railing and frequently extends across the front and sides of the structure.

Although the form verandah is correct and very common, some authorities prefer the version without a "h" (the Concise Oxford English Dictionary gives the "h" version as a variant and The Guardian Style Guide says "veranda not verandah"). Australia's Macquarie Dictionary prefers verandah.
