management — managed under one roof, from the first brief to final delivery.
Complete Renovation Services
Villas and Homes
Renovating a high-value property requires more than a construction crew. It requires architecture, interior design, permit management and project management — all aligned from the first design decision to final handover. At Costecasa, every one of those services is in-house. One team, one contract, one standard of delivery across every project we take on.
The services below can be engaged individually or as a fully integrated package. Most clients engage us on a complete design-and-build or turnkey basis — a single contract covering the full scope. If your project requires a specific service, each page below provides full detail on what is included and how it works.

Why One Company Should Manage Every Service
Sitges has one of the most varied and architecturally distinctive residential property markets in Catalonia. Each property type presents its own renovation context. Here is how we approach the most common high-value home types in the town.
Townhouse Renovation Sitges
The most common source of problems in residential renovation is the gap between
disciplines. When an architect, a builder and an interior designer work independently,
small misalignments accumulate into costly problems — a wall that cannot move because
the structural calculation followed the interior design; a finish that cannot be
procured in time because sourcing was not aligned with the construction programme.
At Costecasa, architecture, interior design, construction and project management
are coordinated by the same team from day one. That coordination is not a management
layer added on top of the work — it is how the process functions. The result is a
renovation that proceeds without the gaps, and a client who has one point of
contact for every question throughout.
