Work at Versailles was at first concentrated on its park and gardens, and through the 1660s, Le Vau only added two detached service wings and a forecourt to the château. But in 1668–69, as a response to the growth of the gardens, and victory over Spain in the War of Devolution, Louis XIV decided to turn Versailles into a full-scale royal residence. He vacillated between replacing or incorporating his father's château, but settled on the latter by the end of the decade, and from 1668 to 1671, Louis XIII's château was encased on three sides in a feature dubbed the "enveloppe". This gave the château a new, Italianate façade overlooking the gardens, but preserved the courtyard façade, resulting in a mix of styles and materials that dismayed Louis XIV and that Colbert described as a "patchwork". Attempts to homogenize the two façades failed, and in 1670 Le Vau died, leaving the post of First Architect to the King vacant for the next seven years.
