IDEO Morph 38, Skye Tower
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.


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."

To Tip
63.9 m / 210 ft
48.6 m / 159 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.

# of Apartments

Number of Apartments refers to the total number of residential units (including both rental units and condominiums) contained within a particular building.

# of Parking Spaces

Number of Parking Spaces refers to the total number of car parking spaces contained within a particular building.

# of Elevators

Number of Elevators refers to the total number of elevator cars (not shafts) contained within a particular building (including public, private and freight elevators).

About IDEO Morph 38, Skye Tower

The Ideo Morph 38 development is located away from the high density and congestion of Sukhumvit Road, in a blissfully green low-rise residential area. Its ordered, pixellated facades provide a contrast to the visual clutter characteristic of central Bangkok. The development is separated into two towers to maximize the building plot ratio, with each building targeted to different demographics.

The lower tower of the two, Skyle is targeted to singles or young couples, offering the smaller footprint of the two. However, the duplex units are expressed vertically to achieve a generous 5.4-meter floor-to-floor height. Due to limitations on unit size and variety, the balconies and the air-condensing units on the outside of the building contribute to create a “pop-up” effect through variation in the façade.

In contrast, the taller tower, Ashton, emphasizes the horizontal and cantilevered spaces, which are targeted to families. The unit sizes and types vary from a single bed with a reading room to duplex units with a private swimming pool and a garden on the eighth floor and a four-bed duplex penthouse at the top level. A 2.4-meter cantilevered living space projects from each unit on the north side, made up of a glazed enclosure on three sides, providing the maximum, unobstructed view. Each unit, facing south, has a semi-outdoor balcony, which acts as flexible space. The double layer of sliding windows allows for a transition between a conventional balcony and an extended, indoor living area.

The two towers are visually interconnected through a folding “Tree Bark” envelope that wraps around the both towers. This outer skin is a combination of precast concrete panels, expanded mesh and planters. The functions of the skin vary from acting as sun-shading devices to covering air condensing units, while the “bark” elements on the west and east side strategically support green walls in accordance with the tropical sun’s orientation. The green walls provide the residences and neighboring buildings with a comfortable visual and natural environment. The buildings are oriented in the east-west direction, helping to reduce solar heat gain. The sky gardens found on both buildings at regular intervals also contribute to this design language, where the development becomes a “vertical landscape” and a part of the natural green surroundings. The addition of significant planter-based trees on cantilevered balconies adds the option of standing at height outdoors under a canopy, and some variation to what otherwise could be a monolithic exterior appearance. This also produces a special sensation on certain of the balconies: that of standing out apart from the building, yet enclosed beneath the shelter of leaves. Additionally, the parking garage in the podium is shielded by green walls.

The green walls are fed by planter boxes located behind expansion mesh, and are installed approximately 625 millimeters from the building envelope, permitting natural ventilation and providing a service corridor for maintenance. A vine system was selected for the green wall, due primarily to the fact that it is easily maintained and cost effective. The vine vegetation is also able to withstand the strong winds and robust weather conditions of Bangkok.. The height of each floor varies from 3-6 meters, which provides sufficient height for the plants to climb and merge into one continuous, green surface.
