The Geometry of Time:In essence, remodeling is covering one material property with another material property. In other words, it is the work of reinterpreting the sentimental meaning of existing material property with new sentimentality. Space is occupied by a person, but the trace of memories of the space and time remains in the physical space, not the place.

New Sentimental Space:The client, who is a TV commercial producer, had strong principles about architecture and clear requirements for the details to realize them. He requested the remodeling of the existing single-family house into office spaces with a new type of sophisticated sentimentality covered with modern materials. Space Reconstruction and Expansion of the Basement:The most important and the most difficult part of remodeling is reviewing the measurements considering the commerciality of expanded space.

It means the scope and budget of remodeling decides the future commercial value. Considering the limited budget and the future expandability, I chose the basement space that can be expanded regardless of floor area ratio as the major site of this project. To secure this parking space, a steel lever pattern was changed to alternate the louver on top, and the stone on the bottom, to create a pattern.

LED units were inserted inside the louver on top to allow various activities at nighttime in addition to the use of space for parking. The horizontal flow of the new exterior marble walls connects to the existing parking space to maximize the basement space for various uses, such as a gallery.

The basement was used to the fullest extent without changing the floor space ratio to leave room for additional expansion. The Geometry of Giwa and the Sentimental Identifier:Giwa (Korean roofing tiles) connotes order. Giwa roofing is also a system of a type of geometric orders. It is a combination of units optimized to endure rain and snow, and an economical system to build the gable shape.

These tiles pair up with one another to create texture and tactual sophistication. Still, the sophisticated Giwa tiles are sometimes placed on the ambiguous borderline. The curved figures of Giwa cluster to form the wavy shapes and the triangular geometry of the gable constructs the order of the past. The existing geometry of red Giwa and bricks contrasts with the gray tetrahedrons of black stainless steel in terms of texture and material sentimentality.

The Reconstruction of Geometry:Black stainless steel tetrahedron blocks numbering 87 form the basic unit that encases the existing masonry walls. The exterior of black stainless steel cubes is a lump of skin made of 530 triangles and rhombuses. The 530 geometric shapes are divided and reconfigured by the bored plates on the top and bottom, and the laser-cut triangles in the center.

The pattern of about 200,000 bored circles and 15,000 geometric patterns filter the light from the outside in various quantities and qualities. Light is reorganized and the space is newly configured. Additionally, the space is given a sense of time by the constantly changing geometric light. Camouflage, Disguise, and Tension:To hide or to reveal? This is the essential question when it comes to remodeling.

Architectural sentimentality denotes the spatial reconciliation between the traces of memories discovered by the architect and the current time. As with most architectural structures from the 70s, the dark-red bricks and the red Giwa tiles are the major components that make a strong statement about the past context. Therefore, the reconstruction of balance and proportion of shapes, not just the conversion of colors, is essential with the new remodeling.

In effect, the materials change themselves through varying degrees of camouflage, such as the geometric lighting, to present new spatial bodies.
