Keiji Ashizawa: home in the centre of Tokyo surrounded by greenery
Each level is planted with green areas such as hanging gardens and patios which organise the levels in a regular geometric grid, like parts of the home which have been stolen away from the building by the vegetation. On the first floor there is a rectangular outdoor area separating the two bedrooms while permitting visual communication between them through their glass walls; on the second floor, the spa garden covers the entire northeast wall with greenery, reaching all the way up to the roof and the rooftop deck.
The lot on which the home stands is used up to the limit because Japanese building regulations require 50 to 150 cm of space to be left free around the boundary of the lot, preserving the old pines and zelkovas, trees native to Japan and China.
Keiji Ashizawa?s new building was originally a samurai?s home, and it maintains a connection with this history through the antiques the owner collects. The care with which these objects and furnishings are situated inside the home suggests that the home might have been designed specifically to provide a setting for them. The home?s concrete structure is concealed within walls painted white like gigantic frames for the paintings that hang on them. Materials such as black walnut in long strips covering the floors and walls both indoors and outdoors and stone maintain a noble dialogue with the work of art about materials left visible.
Finally, the light coming in through the floor to ceiling windows on each level does not strike the walls on which the paintings are hung, already rich in visual stimuli, but laps against the areas at the boundaries of the home which require greater quality of perception.
