Reflections at Keppel Bay Tower 1B
Name of Complex

A complex is a group of buildings which are designed and built as pieces of a greater development.


CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Postal Code

A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

Structural Material

Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.

A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

Official Website

Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."

116.5 m / 382 ft
Floors Above Ground

The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

Floors Below Ground

The number of floors below ground should include all major floors located below the ground floor level.

About Reflections at Keppel Bay Tower 1B

Sited on the scenic Keppel Harbor in Singapore, the Reflections at Keppel Bay complex took its inspiration from the strong elemental forces of the area. Surrounded by water and the lush vegetation of the region, the six towers of the complex seek to provide not only views from each of its residential units to the natural beauty beyond, but to also create an intriguing formal juxtaposition between the towers and their surroundings.

The project brief required that the development achieve a density to meet the client’s goals on the available site, as real-estate costs in Singapore are high. To meet the number of desired units, a set of differing typologies was developed to provide variety in the design and create a unique development while creating a dense complex. Eleven low-rise villas of 6–8 floors each occupy part of the site, creating a gradient to the height of the towers. The towers are one of two forms: either 24 stories and 117 meters in height, or 41 stories and 175 meters in height. Pairs of towers are united with sky decks to provide green space and facilitate connections between them.

The nine sky decks in the complex range from 15 to 24 meters in span, and are full-story trussed steel matrix construction which were assembled at ground level and were strand-jacked in sequence from the highest to the lowest level, to finally maneuver the structures into place. The decks are landscaped, connecting them with the densely planted environment around it and providing a unique experience of a garden in the sky for residents.

The forms and materials of the towers are intended to respond to the surrounding water and air, reflecting back the environment. The crown of each tower is made up of a complex lattice which evaporates into the air, creating a connection between the tower and the sky around it. Each crown, approximately 40 meters in height, is created from cold-rolled tubular steel sections. Within the crown structures are housed three levels of sky gardens that are integrated with the penthouse units. The façade treatment is of varying reflectivity, creating a stippled effect along each surface, much like the water around it.

The artful composition of ever-shifting building orientations, along with the differing building typologies, creates an airy, light-filled grouping of short and tall structures. These forms create an experience where each level feels unique as it is not in alignment with either the floor above or below. There are no residence types which are placed next to one another or seen from the same perspective; the result of this design is a fundamental shift in high-rise living where individuality and difference is not sacrificed.

Comprising more than 1,100 units, the complex is a neighborhood, and the architecture is intended to create a community for its residents. To support the community in a sustainable manner, several conservation measures were taken: energy-efficient lighting and appliances were installed; a rainwater harvesting system is used for irrigation; motion sensors and automatic plumbing fixtures were installed in public spaces; and a large amount of softscaping was employed to reduce heat reflection and improve rainwater collection, which was also in alignment with the goals of integrating the buildings with their context. The project earned Singapore’s Green Mark Gold Award through its implementation of sustainable strategies.
