This document summarizes the BUMPS residential and commercial building project in Beijing, China from 2008. It consists of four residential buildings arranged around a central commercial building, all rotated 45 degrees from the north-south axis. The residential buildings are 80 meters tall. The site plan and building designs demonstrate principles of hierarchy, symmetry, and axis. The larger commercial building is at the center surrounded by smaller residential structures, showing hierarchy. The buildings are arranged with bilateral symmetry on the floor plans and can be divided radially and through horizontal and vertical axes.

1. PRINCIPLES
Building: BUMPS, Beijing, China
Architects: SAKO Architects
Year: 2008
Area: 17949 m²
‘BUMPS in Beijing’ is an integrated project with four
residences as well as a commercial building. It is rotated by 45
degrees from the north-south axis. The residence buildings are
80 meters height.
HIERARCHY The articulation of the importance or
significance of a form or space by its
size, shape, or placement relative
to the other forms and spaces of
the organization. Here, in these
structure we can easily notice
hierarchy by shape & size in the
central commercial building
surrounded by square residential
building.

PRINCIPLES
Plan showing bilateral symmetry
SYMMETRY A condition when elements are arranged in
the same way on both sides of an axis in a balanced
arrangement of equivalent patterns of form & space on
opposite sides of a dividing line or plane, or passing through
center or axis. In the floor
plan of a residential
building, bilateral
symmetry can be clearly
seen. Also the residential
building can be
approximately split up into
radial symmetry by plane
of symmetry.
Elevation
AXIS A imaginary line through the middle of a plane about
which forms & spaces can be arranged in a regular or irregular
manner but in a balanced way. Here, the floor plan of a
residential building in Bumps can be linearly divided by both
horizontal and vertical axis passing through the centre.
