Complete renovation, one coordinated team

What Villa Renovation Services Include

Villa renovation is at the heart of what Coste Casa delivers. Project requirements vary from one property to another, ranging from complete structural redesigns and extensions to high-end interior renovations within the existing footprint. Regardless of the scope, every project follows the same proven management approach: one architect, one project manager, one construction team, and one contract from start to finish.

We renovate all types of detached villas, including older properties from the 1960s and 1970s requiring full modernisation, contemporary homes in need of specification upgrades, period villas requiring careful restoration, and newly built properties where interior and exterior spaces remain unfinished. Every renovation begins with a detailed property assessment and a transparent discussion about objectives, scope, and budget before the design process begins.
