Located in a theft-prone area, client wants a design that is not too open, especially in front and rear area of the building. Responding to this issue, architect designed the front and back of the house with a more solid appearance and disguised openings to avoid exposure the area inside the house from the outside area. Openings to the outside are positioned leading to parks located on the side, front and rear but treated with intermediate spaces that function like secondary skin to hide it from the surrounding environment.

The CROX HOUSE concept is designed by responding to environmental issues. Not only the front facade that look solid to respond unsafe area, architect also design the concept of cross mass to capture natural sunlight optimally from the top of the building by adding openings to the rooftop and adding skylights to several points.

In its layout, the architect divides the house zones into three floors with a semi-public communal area on the first floor, a more private zone consisting of rooms on the second floor, and entertainment and service areas on the third floor. The semi-public zone on the first floor was designed with the concept of an open plan with a minimum of bulkhead by adding spots that could be used as workspaces and reading rooms. Based on the client's request there is also a bedroom on the first floor that is designed hidden and camouflaged with a door designed like a partition. Spaces on the second floor are facilitated by a rooftop garden area, complete with a small pantry on the terrace area that can be used for gathering and barbecue areas, while the third floor is focused on facilitating client hobbies which is playing games and reading. Similar to the park on the second floor, the entertainment area on the third floor is also connected to the small rooftop garden beside it. The existence of a rooftop garden on the second and third floors is one of the architect's design strategies to optimize air circulation and natural light into the building.
