kyoto-based architecture studio alphaville (kentaro takeguchi, asako yamamoto) has sent us images of their newest project ‘roof on the hill’, a private residence in a new development site in takarazuka, japan. working with the solid soil condition of the plot, the single storey design follows the natural slope of the terrain by dividing the floor plan in stepped back intervals.

arranged on a 3m x 3m grid steel frame, the house features three terraced-back levels that climb the topography of the site. a series of small steps connect each stage at different intervals to create a meandering circulation route. private programs such as the bedroom, bathroom and children’s room are contained in box-like volumes while the interstitial space in between accommodates the communal programs such as dining, kitchen and living area.

left in its exposed and corrugated form is an undulating roof that creates an artificial topography of its own. featuring long slits at each fold, an abundant amount of natural daylight enters and illuminates the interior space. the oscillating form also creates a contrasting element to the regularity of the layout, creating a faceted and angled ceiling that plays off the linear division of space.

  • I like this very much. Well done.
    There are many ways to insulate the roof for sound and temperature. The ceiling structure as seen from below is one element. Above that could be sheathing, waterproofing, 1/8″-1/4″ thick rolls of sound proofing, perlins with insulation panels between topped off with standing seam metal roofing. Standard wall insulation and insulated windows. Very quiet Very comfortable…

    I do have to wonder about all the stairways in db without handrails.

  • Not to mention the high-speed rail tracks just above. But it is a nice design. The interior feels a bit like a small alternative theater.

  • Loud when rain falls, cool when it cold outside. Nice idea though.
