Ibiuna Prefabricated

Weekend House for Ohtake

This modular project is intended to be an example of something built by man, but in harmony with nature. The challenge was to design a house that doesn't look like a prefabricated modular house. The solution presented consists of several prefabricated modules connected by open spaces. Another important aspect of the Ibiuna House is the rationalized way in which it has been integrated into the territory. The construction project has not resulted in the accumulation of waste or leftovers and the project is also thermally efficient.

Unique Properties

The architect designed a prefabricated house that doesn't look like a modular prefabricated one. He couldn't deviate from the original modular design, so he put all the rooms in these spaces. If he put these rooms far from each other, then he can make the void between them to be the social area such as living room, dining room and kitchen. To cover this void, he used this industrial roof that can be cut in curves. For the facade, he created some curved walls and eaves to break the rectangular shape of the rooms.

Production Technology

The architect designed the whole structure with the precious help of the Syshaus team that manufactured the house. For the exterior walls, Rodrigo chose a thermo-insulated industrial wall covered with an aluminum plate. The blue curved walls are made of perforated steel plate. The functions are: to break the rectangular shape of the bedroom modules, to give privacy to the rooms and to make the house surprising. The ceiling is made of industrial steel beams. They don't have a formal bathroom, it is actually very integrated with the bedroom. The floor of the living room is wood. The architect’s studio always uses color in our projects. To him, color represents joy. So he wanted this house to be something man-made in harmony with nature. He wanted to show that a prefabricated house is not only something urban. It can also be in nature. Orange was the color the architect chose to be the protagonist of the interior. He wanted to be in contrast with the super powerful green of the nature that surrounds the house. His favorite part of the house is the living room with a view of the trees. It is a wide space that is actually the void between the rooms with an industrial roof. Waking up in the middle of nature is why they didn't put curtains in their bedroom. It is a unique feeling. The architect designed most of the furniture. For the pool, he wanted a curved design to be unusual. The artwork is chosen by his wife. She is an art curator.

Design Challenge

When presented with the idea of The Ibiuna Weekend house, the main issue with its planning and construction was producing a design that felt as part of Rodrigo repertoire while under the limits established by the modular characteristic of Syshaus' manner of production. Rodrigo’s design is constituted as an interaction between the shapes, volumes and the area in which those projects are scaled, producing unique manifestations. These qualities may prove worth on a daily basis, but when paired with a sense of mass production and celerity, they tend to put this relationship to the test. Regardless of the trial ahead, answer where promptly presented. By narrowing the scope of utilized colors, separating the prefabricated modules and reducing the total numbers of curves distributed in the project to the necessary minimum. Rodrigo was capable of producing something that was still reasonable for Syshaus and still kept a sense of creativity and unusualness to the final product.

Project Duration

Location: Ibiuna, SP, Brazil Project duration: 06/2023 - 12/2023

Operation Flow

The Ibiuna Weekend house is set as a tenet and mould to a whole line of Syshaus modular houses. Being delivered across all regions of Brazil in a short span of time, primarily 120 days from the purchase. Furthermore, the manner in which the house is built, with the void between the modular areas, allows customization beyond just the colors of the walls or the aspect of the floor, according to each end user's own preferences and behaviors. Being able to differentiate one model to another, enables a non-standard line of products, enabling different sensations, benefits and necessities to each household.

Inspiration

The architect, his wife and their three children use this weekend house. It is their weekend house in the country. They don't live there, they use it to get away from the city life, to relax after a busy week in the city and for the children to be in deep contact with nature. They chose a house in the city of Ibiuna because it is an easy drive from São Paulo and it has a lot of nature to disconnect from the city.
