‘tutanga house’ by nishinomiya-based practice shogo aratani architect & associates is a three-storey private dwelling for a couple and their child in osaka, japan. constricted by neighbouring buildings to three sides, the design steps back in the front and the back as well as leaves a meter-wide buffer zone between itself and the adjacent structures to gain natural sunlight into its interior.



street elevation




situated on a long and narrow site measuring 6.8m wide and 17m deep, the layout of  the interior space was singularly dictated by the aim of establishing generous windows that do not cross its sight lines with the windows of the neighbouring houses. the third floor is manipulated to provide four void spaces to provide sunlight to the levels below. featuring a pivoted wall partition, the voids are read as geometrical cuts in the floor slab. the resulting height difference gives the interior a larger and open sense of space.



ground floor room looking out to boundary wall




in order to gain both privacy and light, the ground floor incorporates a low-lying strip of windows that looks out into the meter-wide gap that runs along the length of the site. a bounding wall constructed out of stone serves as a fence between the house and its neighbours.

  • Nothing special

    Lotr says:
  • Well, I think they gave a great deal of thought to bring that amount of light in the spaces, taking in mind the house its surrounded from three sides and is constrained to natural light! I would say, it something!

    Davis Stra says:
  • I really like what is being done for ‘home architecture’ in Japan. The spaces, the simplicity, the feel and materials of their buildings. Their projects are complex in their simplicity and practicability. This house also goes in that way. It make me like architecture again.
