Z-house by Hohyun Park and Hyunjoo Kim



Korean architects Hohyun Park and Hyunjoo Kim have completed Z-House, a residence in Gwangju Si near Seoul.


Situated at the top of a steep hill, the building is surrounded by woods to the west and has views across the surrounding mountains to the south.


The Z-shaped roof is made of black zinc and wraps around the upper level of the house.


The upper level is clad in red cedar wood in contrast to the lower level which is finished in basalt stone.


Photographs are by Jungmin Seok.


Here is some text from the architects:


In composition of space, relationship among programs and circulation are played important role.


Ground level, which is divided by kitchen/Dining and living area and upper level, which is divided by children rooms and master zone are crossing at division area.


By this manner, space is gradually ascending from entry to master zone.


Next thing to consider is to make dynamic space by changing size of space and by leading sight.


High ceiling at the entrance corridor is more emphasized by sunlight through skylight and a wall, which is faced at the end of corridor, inducts eye to dining area.


At this point, the ceiling height is suddenly changed by overhead ramp. High ceiling living area appears through low-rise 3 step staircase, which is crossing outside water pond and inside plant area.


From living area, space bifurcates to library at lower level and to upper level.


Master zone, where is a climax in space scenario, is connected by a corridor and a ramp from children’s room at upper level. Master bedroom is entered through open bathroom and powder room and reconnected to entrance corridor.


Shape of the building is planned to follow the space scenario and roof, which is covered by black zinc is wrapping around upper level mass and form a homogeneous and muscular shape.


Contrarily, lower level masses, which are covered by basalt, stand rigidly.


Water pond and inner plant space are inserted at the crossing point of lower level mass and upper level mass.

    Some nice moments in that house. But, my god… it’s so hard to prevent your eyes from being drawn to those super thick, black window frames that entirely take over some of the spaces!

  • shreyank

    great finishes…. but the only thing is it looks more like “S-HOUSE” unless the architects have been working for hadid a lot then… i can c where the “z” is coming from…. none the less…. great work…. great spaces…. great finishes… all in all… “s”uperb effort……

    I didin’t like the ramp it seems useless. And why did they use so many differnt materials in every different room? On the other hand i loved the main stairs and the bathroom. Having a shower with watching the outside from big windows. Hmm what a great start to a day.

  • Juampi Z

    stunning! nice stairs… I love the dinning room!

  • junihaoni

    hasn’t the mobius strip-inspired spatial organization been done before by UN Studio in their 1998 Mobius House? But this one certainly has more life and soul in terms of the rich materials and colors used.

    This house just doesn’t know what it wants to be.

  • Maham Z

    a collection of nice(!) views, but no harmony!

  • slater

    love the house but what is it in the asian design culture that makes them want to have a clear view of the toilet from adjacent spaces? This example appears to be not nearly as bad as some other postings here since it is only visible from the rest of the bathroom but I’d need some more privacy or i’d have stage fright!

  • Stuart Haffenden

    my ass is on fire

  • Trish

    I don’t see a clear idea coming through. Nice moments but overall it could use more harmony in materials.

  • Yunji

    I don’t know much about archtecture, but this house looks great. And, more than anything, I love the photos!!!

  • ivan

    A good example how an attempt to make a modern architecture has ended in traditional forms outside with vertical plank cladding. One can not guess what a dramatic intersection is there inside. Lots of casualities in interior

  • eric j

    A little too spacious for my taste, but this is absolutely gorgeous. I’d have to agree with Jeroen about the window frames though. And I also agree that there isn’t much harmony in the materials, but I don’t think that’s necessarily a bad thing.

    Too much is not enough!

    I’m Korean university architecture student. I have to make this house model scaled 1/100. Could you give me this house CAD file? Please send me e-mail:
