Corten House is an urban house located near the largest park in the city of São Paulo, Brazil. The site, long and narrow, contains the program of the house and, its residents, not only have a small external deck with a fireplace on the ground floor, but they also make use of the rooftop and, especially, the park itself for leisure.

ground floor plan

The facade of the house is made of Corten weathering steel. The dialogue between the rusty texture on the outside and the stone, wood, white mortar and the glass build the space. The front door of the garage is made of vertical wooden strips and opens entirely onto the street. The main entry door to the house is also made of wood and, despite being of a color similar to metallic plates, the texture and the presence of the material itself, distinguishes the suspended steel box of the frontal façade. The back façade is composed of a glass curtain that confers transparency to the opaque steel box and a suspended volume which contains movable wooden brises. The interior walls of the lot are made of Stone.

The interior plan for the ground floor is simple: an ample room with a ceiling height of 5.2m and four folding doors that completely open out to the deck and external fireplace, dissolving the limits between interior and exterior; in the living room, a free wooden volume houses the kitchen and utilities program; between this volume and the entrance door there is a staircase that leads to the mezzanine.

The mezzanine, on the wooden volume, is a singular area for the home-theater. From here there is another staircase leading up to the third floor, to the private program of the house, the three bedrooms. The master bedroom, in the back, has a wooden panel of brises to filter the light and can remain completely open.

roof plan

On the rooftop of the house, there is a wooden deck protected by glass guard-rails. This space functions as a solar with a heated pool and a view of the city of São Paulo.

    Marcio’s lines are clear and simple, and the result, amazing. Always the same comments about his houses, that’s a good sign! beautiful.

      almost no walls and you call it a waste? waste of what? isn´t the whole program there?
      Or should it be all condensated in small subdivisions and short heights, so there was more space left in the…. amosfere?

      wasting of space? i do not understand your definition of a waste, but i smell jealousy there.

    Where is the delight? Where is the soul in this design. I like the plan but there seems to something missing.

      probably… but its still very good architecture… this isn´t and shouldn´t be understood as a fashion profession. Good architecture never goes out of style

    A good design, stuck in the 90′s is still much better than some BS, coming from the future. I like the ‘ box within a box’ theme, carried throughout the project. The double height living room, besides being a wonderful space, also raises the third floor and the roof deck, so they’d have this terrific view of the city.
    Excellent job!

    What’s with these Brazilians. Didn’t they read Jencks? Modernism is supposed to be dead. Actually, I like the way these guys continue to carry the light of cool, sophisticated modernism, when the rest of the world has gone chasing schizophrenic angles and digitally derived blobs…

      Hear hear. I love what the Brazilians are doing. Confident, sensual, elegant, comfortable, functional modernism. Keep it coming.

    This is a knock off copy of Asay Weinfeld’s Casa Cinza. I find Mr. Weinfeld’s Casa Cinza design superior. While I like Marcio Kogan’s designs, I find this copy of Casa Cinza like the gaudy sister.

      I’m starting to get sick of these copy/paste comments because they simply discredit the work of architectso who analyse, understand and reinterpret previous works in order to think and produce good architecture in a different place and for a different client.

      • Thumb up Thumb down 0

        I agree with you Damien about duplication of great work. My guess is the client hired Kogan to create an enhanced version Casa Cinza. As I mentioned I like Marcio Kogan’s work. In this instance, I prefer the scale and make up of the original.

        Like an album re-make. Some are better than the original. Some are not. I have no doubt it is the perfect house of Corten. In any event, pointing out history and the roots of works helps in understanding them. I apologize if you were personally offended.

      Ekalb, as far as I know, Kogan and Weifeld were partners in their beginings.

      The Fassano Hotel was a project they both did together.

      Their architecture is similar indeed, but not because they copy each other, but because they’re both from the same era and school of thought of brazilian architecture…..and having the same pool of rich clients with similar taste does reflects in their projects.

    This is my favorite of Kogan’s houses. A simple gesture, a long pavilion where light and space flows freely. The innovative stroke in the mezzanine, a box within a box. That block is also instrumental in keeping the grand scale of the pavilion homely. And the corten steel, the wood, the white, the lighting, the details…impeccable.

    Nice! ;)

    I do love the lines of this design… but on a more practical note, how does one replace a blown bulb on that 5.2m ceiling?
