The primary objective of this project is to establish a research hub on a tropical island that accommodates researchers for living, working, and exploring. There are several aspects that have been given significant consideration throughout the design process. Firstly, the integration of the building with nature has been emphasized by utilizing the hilltop's topography in the design to create a harmonious balance. Secondly, the design considers energy and environmental friendliness by utilizing solar power and rainwater harvesting, making the building self-sustainable.

At the island's scale, the building appears to float, making it stand out from the surrounding environment. However, at a smaller scale, the use of slicing elements creates a connection between the building and the site, resulting in a public and private space beneath the volume. The building's interior features a stepping-up library that attaches to the shell and a central multifunctional hall that creates a robust community space. Additionally, gaps at office levels provide a varied plan and roof.

The use of GNC materials allows for the growth of plants on the facade, while the greenish cast glass beneath the massing offers an exciting texture that softly illuminates the walls from inside at night.

Collages: Nature, Geometry and Activity

The preliminary collages suggest that architecture can serve as a mediator between people and nature. Similar to land art, abstract geometries can be linked to natural or geographical elements. Although there may be a stark contrast, architecture can inspire people to think about nature.

Site

The proposed diagram depicts the volume in relation to the site, which is adjacent to the hilltop. The diagram highlights two key characteristics: a 360-degree panoramic view, and a slicing element oriented from the valley towards the seaside.

Identity: Link to Nature

The current buildings on the tropical island lack a strong connection to the surrounding environment despite their initial intention to do so. For example, the hotel's semicircular design was meant to embrace the natural surroundings, but instead created a large enclosure. By separating the buildings' features into inward-facing and outward-facing elements, it becomes clear why their identity is unclear, and how it can be reshaped by redefining their relationship with the natural world.

The model study examines the scale, geography, and size of the building. Typically, a hilltop building can appear too introverted at the M scale, resembling a castle. However, when the building is integrated with the surrounding terrain, it can create more space and opportunities for activities.

Model Study: Typology and Density

The objective of the model study is to identify a typology that achieves a balance between the internal space and the site adaptation. While a centralized space is beneficial for fostering a sense of community among researchers, it may also create an enclosed environment that fails to connect with the surroundings. To address this issue, the slicing concept is introduced, creating voids that allow the building to "breathe" and interact with the natural environment.

Site Adaptation

To achieve a balance between the interior space and connection to the site, the design uses a centralized space and a slicing concept. The slicing elements divide the space below the 'Superbowl' and expand to create areas for public and research activities. This design approach provides a dynamic and flexible space that can adapt to various functions and users while maintaining a strong connection to the surrounding environment.

Environmentally Friendly Design

Passive energy-saving strategies were employed to establish a harmonious relationship between the building and the surrounding nature. In order to counter the tropical heat, the building incorporates a pond which helps to cool the air. The chimney effect and greenery in the building's gardens further enhance natural ventilation. Rainwater is collected by the building's roof and vertical greenery, and then utilized for both irrigation and daily needs. Energy is sourced from two directions - solar power and ground heat.

Structural Scheme

The third level of the building is designed as a truss system that is reinforced to support the weight of the overhanging volume. Meanwhile, the second floor is supported by a truss structure deck. The bow-shaped structures distribute forces in multiple directions, providing structural stability.

In addition, the light-weighted structures create a space on the roof that is suitable for a gym deck and planting. The columns are concealed within the line elements, which are made of double-layered cast glass to create a public space for various activities.
