sou fujimoto wins taiwan tower competition

the proposal ’21st century oasis’ by japanese practice sou fujimoto architects in collaboration with taiwanese firm fei & cheng associates has taken first place in the taiwan tower international competition for taichung city. derived from the trunk of the taiwanese banyan tree, the ornate structural system will frame a semi-outdoor interior space generating a dappled light quality as found beneath a leafy deciduous canopy. positioned within a green belt, the building will become an urban retreat with a green rooftop ‘island’ floating 300 meters above the city. representing the divine isle of formosa, the garden will reintroduce the beauty of nature into the urban fabric while becoming a symbolic landmark visible from many points throughout the city.



conic building height atrium with perimeter ramp circulation



a variety of renewable energy systems and passive design techniques have been integrated into the design including rainwater harvesting, solar hot water panels, wind turbines, photovoltaic cells, ground source heat pumps, desiccant air-handling units and natural ventilation due to the inherent stack effect. mitigating the impact on infrastructure, the collection of systems will reduce half of the consumption and carbon emissions. the exterior effect of the steel construction is produced with vertical and inclined perimeter, inner and intermediate columns as well as spiral beams and roof beams. the presence of leaning vertical elements – comprised of 80mm diameter hollow tubes – will provide lateral stability from wind and earthquakes loads. comprised of two intertwined units, the spiral beams stitch together the outer and inner row of columns from the ground floor to the roof plane, preventing buckling due to their slender proportions. a conic atrium is maintained within the center of the building’s footprint spanning the entire height of the tower.



view from the surrounding context



adjacent to cultural districts, the program will consist of museum and exhibition spaces. visitors circulate upwards via an elevator placed within the acute point of the triangulated footprint. the facades contain LED lights which create an airy and hazy effect which changes in color and intensity. the exterior transitions into a sleeping state creating a starry  illumination which evokes a similar effect of chinese lanterns.

    Hasko says:
  • love it

    ashriver says:
  • Awesome! pushing further the high rise typologies

    Malaparte says:
  • where’s the floors?

    mash says:
  • What about bird flight patterns?

    savannahjones says:
  • do you really want this Sou?

    FLW says:
  • A handful of good life, is better than a bushel of learning.

    mm says:
  • billiant!

    kukubee says:
  • good luck managing the wind shear for that green roof 300 meters up!

    grahampuba says:
  • Scale is way off! Are we back to the 60s superstudio age?!!

    LL says:
  • So Left-of-Field it’s genius, though I hope it doesn’t become another Pompidoo-doo.

    Alex Michael aka siloboy says:
  • R u serious??

    dna500 says:
  • I hope he is not serious.

    YY says:
  • insane but yet creative. i worry what it will affect people’s life. when a driver look at the lights at night, he may lead to car accident. some people like me dont like the high height. i would feel awkward if i sit on the rooftop. luxury feel things dont need for my life into easier and simpler. please more untouched nature!

    cw says:
  • Please don’t do that!

    mvmntmdrn says:
  • the first of its kind, a truly innovative idea! i cant wait to see it in person. i applaud the daring structural design.

    and it will clearly stand, it may even be overkill structurally with like a million columns but together they create a beautiful effect.

    pbm says:
  • Ga-bej

    MoOdiR says:
  • Excellent concept,thrilling and adventurous.Scary and daring but thats the beauty of construction and technology.It certainly is ahead of its peers when it comes to creativity and design,although at the end of the day should not be built for many other reasons that overshadow the reasons as to why it should be built.Hats off to best high rise typology of the year thus far.

    Archipunk says:
  • Great

    ton donders says:
  • What about the embodied energy of all that steel? If it was bamboo, now that would be interesting, not to mention more true to the story of the tree…!!

    Dave says:
  • architecture vs fireworks

    israel says:
  • mmmm feels such wasted space in between. why not more gardens moving up even i get the concept of canopy. Also being Parisian, just wanted to say.. the eiffel tower was built in 1889 and is more a symbol of the 19th century than 20th century… industrial revolution and all…

    coubras says:
  • its 2011…
    lets raise the bar a little higher please…

    sciarc says:
  • I suggest please listen to mvmntmdrn. It will be good for all of humanity.:)

    mvmntmdro says:
  • sou, please build this in your hometown, don’t screw other cities.
