This project involves the renovation of an old building nestled deep within a forest along a coastline in Northen China, transforming it into a tranquil vacation retreat.The existing structure features a concrete frame construction. Our renovation seeks to break the building’s isolated and enclosed facade, fostering a closer relationship between interior spaces and the surrounding natural environment. The design reconfigured the internal layout to create a new vacation lifestyle, inviting nature into the interior as fully as possible. Working within the constraints of the original column grid, we reimagined the space by treating structural columns flexibly—either concealing or exposing them—to enhance spatial fluidity and establish a new architectural order.
