1. TOPAZ Shin-Okachimachi
Comments from the Jury

The design of elements like sashes, partitions, and balcony
railings in high-rise residential buildings significantly affects
their exterior appearance. TOPAZ Shin-Okachimachi
incorporates triangular parting walls into terraces created byoffsetting rounded slabs and rectangular units. The idea of an
exterior appearance created by parting walls without the useof partitions is innovative. The parting walls are connected atangles that echo the boundaries of the site, forming a starshaped outer wall that minimizes any sense of encroachingon or excessive domination of the surroundings. Thin slabs
and transparent wire mesh railings emphasize the parting
walls, resulting in a building whose appearance changes overthe course of the day.

Characteristics of the Property

This property represents the first phase of theseries rental residential brand with which
ES-CON JAPAN is currently involved. Reflecting the theme of connections to the space outsidestructures, this residential building leverages the open spaces at the front and the rounded exterior
to create a structure with a landmark-like presence. At the same time, the design minimizes any
sense of encroaching on or excessive domination of the surroundings. The individual residential
units incorporate wire mesh railings on their balconies to achieve airy, well-lit spaces. In communal
areas, the windbreak room features original artwork commissioned specifically for this property anddisplayed to be visible to pedestrians walking past outside. The landscaped entrance approachprovides both residents and the local community with opportunities to enjoy both art and greenery.

2. ESCON Kudankita Building
Comments from the Jury

Removing columns from the corners of a small office building would, of course, cause the structure
to collapse. Thus, the columns are located a slight distance from the corners of each side. With twocolumns on each side, beams are installed between opposing columns, forming a lattice-like shape,
which results in an office building without columns at its corners. This simple idea is highly effective.
From the interior looking out, the outside view appears to continue seamlessly around the building.
The wave-patterned extruded cement panels used for the waist-high walls are exquisite. The painthue grows lighter as the floors climb higher, creating the sense of the building blending into the sky.
Despite an allegiance to a marked orthodox modernist style consisting of waist-high walls and ribbon
windows, the design gives the building a light and charming form.

Characteristics of the Property

This property is an office building that makes the most of panoramic views of the Imperial Palaceand Mount Fuji. To create office spaces with fine views and a sense of floating in air, ES-CON JAPANinstalled large windows on the south, west, and north sides; constructed the building as high as
possible to reduce the building coverage ratio; and devised an ingenious technique to eliminate
columns at the corners. The ceiling beams on each floor are half-exposed and incorporate linear
lighting to realize a lighting plan that is softly luminous while emphasizing the building’s structure.
These elements create compact spaces that are full of diverse charm and offer various experiences,
achieving an office building that reflects creativity and encourages flexible thinking.
