About Roof House Residensial

Proyek Roof House, berlokasi di atap showroom mobil di Kermanshah, menantang keyakinan konvensional tentang ruang hunian. Proyek ini mengeksplorasi cara alternatif untuk mentransformasi konsep rumah dan menggeser pemahamannya dari perspektif baru. Proyek ini menafsirkan ulang rumah generik melalui tiga konsep kunci: Destruksi, di mana kekuatan eksternal mendeformasi rumah; Eksplosi, di mana elemen struktural dan non-struktural menonjol dan terlepas dari puing-puing; dan Ekspansi, di mana objek mendominasi yang lain dengan menyebarkan esensinya.

Unique Properties: "Roof House" is at the entrance of Kermanshah providence, Gilane-Gharb, located on a flat roof 15 ×32 meters of a car showroom. The location of the current situation shows a house in a non-residential, somehow industrial area. In general, at the beginning, it challenges the public beliefs about the location of the house.
Dimensions & Packaging: 15000 mm × 32000 mm × 20000 mm

Production Technology: To integrate it with the existing structure, the framework of the original buildings was extended to ensure continuity with the new construction. Also, the LSF (Light Steel Frame) system was utilized to reduce the structural weight of an extension.
Design Challenge: This project started from a generic type of house that existed in our common sense. Therefore, these questions were raised. How can we transfigure the house concept in another way?
How is it possible to shift the understanding of the house from our perspective?
Research: The main purpose of this project is to experiment on the generic model of the house. Hence, for this idea of transformation of the generic object, we are following three strategies to execute the concept of form. The first one is Destruction, which emerges from the external forces on the object. The second one is Explosion, in which the object is exaggerating its properties to transfigure itself. And the last one is Expansion. In this strategy, the object’s features infect the surrounding objects and try to disturb their essence.
Inspiration: The project began with a generic type of house that exists in common understanding. In this context, the question was raised: how can the concept of a house be transfigured in a new way? How can the understanding of a house be shifted from a different perspective? "Roof House" is not merely a generic house; rather, it represents what remains of the generic house. This is referred to as object debris, a state that emerges when the conventional perception of a house is dismantled.
Project Duration: The Project Started in January 2024 and finished in june 2024 in Hamedan, Iran
Operation Flow: So as we can see, three keywords indicate our path during the project.
The first one is "Destruction". Destruction is the method which the object itself is demolished by some external forces that are pushing pressure on our generic house to get deformed from its previous state. The second keyword is "Explosion". When the object exaggerates its elements, such as structural properties (beams, columns) or non-structural things (windows, doors, or some of the roofs), we can realize that the explosion is happening inside the house. Somehow the object is withdrawn from the debris itself. The last one is Expansion. In this way, one of the objects in this house is trying to dominate the other objects by infecting or grasping the other object's essence. in "Roof House" a few methods were executed to evoke our object to emerge for us these concepts of form which are occurring in the generic house. As you follow the drawings in the project, you can see the pool on the roof as an object distributed itself by expanding its material on the surrounding objects. Or you will see some destructured objects disclosing themselves by overtaking the current existing generic house.
