The project consist in the reconstruction of building of XIX century, inserted in the Lapa/Prazeres district.

The pre-existing build was in an advanced degree of degradation, the facades and the sidewalls was the usable structure.

The strategy was to replace the old “organ” – the interior structure of wood and plaster, by a new one, also of wood and plaster, trying to get the compatibility of the whole “body.”

The inside space of organize in which floor by a functional structure in the center of the house that includes stairways, bathrooms and closets, leaving one free space to which side of the house, that can by bedrooms or living rooms, with variable dimensions.

The central structure in wood releases the loop read of the solid boundaries, clarifying the relationship between existing and new.

The reconstruction consisted in strengthening the existing walls with a “skin” of concrete with 7cm esp., and the construction of slabs with beams of plywood “KERTO” 20x7cm, applied to the width, with a spacing of 41cm. Above this system of beams are the blankets of sound insulation and wooden floors.

The structure of slabs is apparent and painted in white, giving scale and character to habitable spaces.

    We don´t know how the building was before, but it turned to be a very good renovated town house. The façade blends modern and traditional very well.

  • odris

    Didn’t like it.

  • LargoJax

    It looks like they achieved their goals and it ended up being a sensible yet stylish habitat. The angled ceiling treatments make for very interesting architectural interiors. My only problem is general lighting – I don’t see any. Concealed ceiling lights could make a huge difference, saving floorspace as-apposed to corded floorlamps (nothing against a nice accent floorlamp though), and looks cleaner. Damn, there’s always something!

    The design firm does some interesting projects. I really like the design sensibility of Portugese, Brazilian (Latin etc.) contemporary architects. They incorporate natural materials effectively into very liveable homes. This one is more on the minimalist side though, but still very aproachable…

  • lucyp

    I really like this structure I like the way the windows and internal walls have striking corners and the way the light reflects off them with white walls and wood floors it is a great example of good residential architecture.

    Wonderful project, great piece of refurbishment! Kudos to the architect, it would be great to have some more detail drawings and maybe photos of small details.

  • sullka

    Excelent PRoject!

    Now, my only 2 cents, would be be:

    1- No need for doors between the kitchen and the living room, just leave both hallways open, it would emphasize the idea of the floating central service core.

    2-In the same aidea, I would had placed the kitchen agains the bathroom, again, making it really a central service core.

    this is just stupid…boring…redundant
    Like almost all Portuguese architecture, white Siza wannabes

    Oh, and the Herman Miller chair…very original, really nice

    it’s funny because I don’t think anyone knows how far behind Portuguese architecture really is, except for the Portuguese themselves.

  • Fino

    I think this is well done and sensible at that. Maybe a little too minimalistic, but it’s not like that can be changed with interior paint, texture, etc. Quite tranquil, but a little on the boring side. I still love this though.

    that is all.

  • Gomer Jones

    Derrr…. I have never designed anything myself. Have no idea about the process. Duh, and really hate the unoriginal Herman Miller Chair. And derrrr…… really think the Portugese are behind. Because in architecture, behind means obsolete. And derrrr, I am very critical without any ability to derrrr articulate a real point except what the media has fed me derrrrr. Blot!

  • Rick

    Why is it that, when criticizing one particular building designed by any given portugese architect, detractors need to speak about Siza and the whole portugese architecture? Unless, of course, you’re a portugese and wished for being, let’s say, in Dubai, or maybe in China. Look at Odris, he just didn’t like it… actually, I think Odris’ comment was way deeper and more meaningful than the one from donedone.

    @donedone “…I don’t think anyone knows how far behind Portuguese architecture really is…”

    Ok… That was… What is the word… hmm… STUPID!!!

  • Jeison Gelaki

    Donedone, você poderia ter elaborado melhor seu comentário…
    (this is in portuguese, sorry!)

    • paleologo

      The interest in portuguese architecture is the sensibility for everything, for the territory, for the place, for the light, and portuguese manner of working is unic, becouse they are no t abble to do monters, like big metroploies out of scales, is not being behind, is being human, caracteristic very rare in our days in the world, where it looks the drawing or a huge scale, or awful aberrations that can destroy an whole city. In New York is history and the fact of being in an island was abble to have a massive huge constrution, and few are the places like that. And the portuguese work, more than letting in the world is mark, is to know to read the place and search for what the place asks.
