lisbon architecture triennale: a house in luanda winning design

organized and promoted by the lisbon architecture triennale with luanda triennale, ‘a house in luanda: patio and pavilion‘ is an international competition for the best design proposal of a single family unit house in the angolan capital. the brief challenged participants to consider the demographic and economic climate of the city, which is undergoing an intense process of transformation, and provide a design that allowed for evolutionary solutions with low construction cost. the winning entry by pedro sousa, tiago ferreira, tiago coelho, barbara silva and madalena madureira from portugal largely utilizes rammed earth wall construction for the structure and a collection of patios to connect the house together in a central exterior corridor.

defined by six patios, the house is separated into different functions: kitchen and living room, bedrooms and restroom. the patios are linked together, acting as a circulational spine to the house, ensuring that the interior has a permanent relation with the exterior. to make the project affordable and self-constructive, the design uses a rammed earth wall construction system. the local natural material is fire and sound proof, and an excellent thermal mass for the climate.

— the international design competition was the most participated competition of ideas ever to take place in portugal. the jury consisted of alvaro siza vieira, joao luis carrilho da graca, fernando mello franco, barry bergdoll and angela mingas.

  • Uma ideia maravilhosa, sóbria, inteligente, funcional e, me parece, não muito cara! Linda!

    Vania Pinto says:
  • Love it

    Nils says:
  • great job! More of this construction should be taking place around the world. Very economical.

    Jeff says:
  • Era capaz de fazer melhor

    Luís Valido says:
  • genial.

    marina says:
  • they don’t know? Concret is not good for roof. It act like a stove.

    Gethus says:
  • I don’t know how the dwellers are going to cook..since there’s no kitchen…and the corridor like this…what about cold, rain..and wind?
    And about the accesses well…it seems to be quite dangerous, should have more vehicles way.

    As an African I wouldn’t like to live there.. OK the patios are very nice…for a parties…but…we African wish more quality…

    And we actually have cold station, for us that is cold…and what about the rain..wind…

    It could be better than this…wish they wont build it…

    almeida says:
  • they have not done their homework on rammed earth.
    it will not look like that unless they import soil from different regional areas, giving it the different colors. it cannot handle some of the proposed span and won’t handle the load of a concrete slab roof. Not to mention the formwork that it will take to construct and pour a concrete roof is very intense and costly and the walls will need to be braced so that they don’t buckle outwards. this is a feel good project with nice visuals but rammed earth is very costly, labor intensive and not something to be done simply with local labor resources. do more research!

    guy who spent a week at a rammed earth workshop says:
  • Great pictures and very interesting article, congratulation.

    Sylvain says:
  • Very smart plan, nice shapes but could be technically better.
    Roofs are too heavy, and rammed earth seems a bit irrealistic in that case.

    Whatever, congratulations to the designers !

    H.R, Central Africa. says:
  • With so many designers involved, the project should be much better.

    And why did they separate the family with so many patios? It´s an unpleasant home.

    victor says:
  • very interesting, nice. great job!

    peter dudas says:
  • Patio and Pavilion is about a Peter Smithson’s manifesto in 1956. It says that it is necessary a patio, to have life quality, to be together with nature and look at the sky and a pavilion to our intimacy. This is an exploration about that (intimacy, exterior, both of them mixed, etc).

    This is a proposal for a house in Luanda, is not a finished process. That kind of things about the roof is something meant to be combined together with an isolating material later, is a posterior phase of the construction of this idea.

    S.C says:
  • It looks more a colonial compound or prison.

    What happens when it rains as all the roofs slope inwards – You to have experienced an African rainstorm to know what I am talking about.

    Not a lot of cross ventilation or natural light.

    Johnnie Autard says:
  • I think the concept is interesting, but i have to agree with “almeida”. I expected the winner project would provide more living quality, after all, the goal is always to come up with solutions that improve people’s life, not sort of keep the level that they already have. Also, i believe it’s kinda contraditory the fact that rammed earth was used because of self constrution, but then the roof is a concrete slab (and in order to make rammed earth to look like that, major work and costs are involved). For these reasons i feel it’s a “pretending to be” solution. Pretending to be a self constrution solution, pretending to be all made in rammed earth, pretending to be low cost…The concept is interesting, but the results aren’t so much.

    Peter says:
  • lots of separated rooms= maximin perimeter involved= very expensive.
    lots of connected patios = tiny spaces instead of a good livable space.
    Earth construction= great amount of water spent in construction
    Heavy roof = no climate-conscious design
    Maybe, the problem is the jury.
    Maybe we have little information to evaluate tihis good-looking solution =(

    Adrian says:
  • this is not a practical solution.. in hot weather rooms will be really hot due to the concrete roof. in rainy season patio will be a swimming pool.
