             The apartment
            building is part of a large scale public housing reconstruction
            project located about 15 minutes from Gifu City by car. Four women
            architects were selected under the coordination of Japanese
            architect Arata Isozaki to execute the projects. This linear Wing
            designed by architect Akiko and Hirosi Takahashi sits on the
            north-west part of the site where the idea for the overall layout of
            the development was to run the buildings around the perimeter.  |

                   The
                  Takahashi Wing housing units has been designed with a
                  relatively shallow depth in which a half-void slab system has
                  been employed. The resultant ceiling is composed of continuous
                  series of half-circles giving the building a style of its own.
                  Wavy glass panels are employed between the housing units and
                  the boundary wall, avoiding the creation of a ‘light/dark’
                  hierarchy across the north- south living spaces.   |

                   The room
                  type unit plans can be considered as a means of
                  standardization, in which all spaces are based on co-ordinated
                  dimensions. Although such a co-ordinated dimensioning is
                  applied in a mid-rise linear apartment block, which imposes a
                  different constraints and opportunities as oppose to Hong Kong
                  residential towers, it shall be considered as a basic
                  principles in building design. 
                   
                  The uses of movable partitions and movable furniture allow
                  freedom of rearrangement of apartment layouts. The
                  appropriateness of such a provision largely depends on the
                  living style of the users, yet the wider application of the
                  idea might contribute significantly to the design and
                  construction of housing units in Hong Kong context. The
                  internal layout with employed movable partitions allows
                  adaptation of the apartment to new uses, new users, and
                  changing family composition without resulting in generation of
                  much C & D waste. The acceptability of movable
                  partitioning depends mainly on the type of occupier, some of
                  whom might even find it interesting. On the other hand, the
                  fixed brick wall largely used as internal non-load bearing
                  wall often requires the users to adapt their living style and
                  pattern to the "designed" layout. If such a fixed
                  layout can no longer be adapted to, the unit will usually be
                  refurbished resulting in generation of additional C & D
                  waste.  |

             The half-void
            slab system employed generates a pattern of continuous series of
            half-circles on the ceiling uniquely for the users of the building.
            Such a uniquely integrated pattern, which can also be seen from
            outside, creates a visual excitement and adds character for both the
            inside and outside. Some of the slabs are further extended to form
            the balconies of certain units in a rhythmical way generating an
            external pattern uniquely of its own. The pattern is further
            enriched by the light and shades cast from the structurally
            integrated balconies. The monolithic image of the building block is
            dominated by the rhythmic pattern and structural expression, and
            thus being dissolved.

             It is clear from
            this building that the employment of coordinated dimensioning does
            not trade off the possible rhythmic pattern in modular building
            design. In addition, standardized design also does not trade off the
            adaptability of a space. Although each unit is standardized based on
            a coordinated dimension, the internal usage and character of all
            the units are varied. Each unit is being adapted to the style and
            preference of the user and such a preference shall or shall not be
            pre-determined is still debatable. However, it can be considered as
            a means of reducing C & D waste in the long run. 
             
            On the other hand, there is a potential of aesthetic expression
            inherent in the structural elements as illustrated in this built
            example. The structural elements can possibly be employed as a means
            of architectural expression and generate a character of its own
            along with the standardized design.
