Why is villa construction timeline longer than a standard house?

Villas typically run ten to eighteen months depending on scale, structural complexity and finish level, compared with a shorter timeline for a compact house, because outdoor works, longer structural spans and a more extensive finishing scope all add sequencing time. Outdoor works such as decks and landscaping sometimes extend slightly beyond structural completion of the main house. Building in this longer runway from the start avoids the frustration of an unrealistic handover date set against house-scale assumptions.
