Twisted Form Featuring Sustainable Glass and Concrete with Integrated Green Terraces

Project in-detail

A twisting structure of glass and concrete integrates landscaped terraces, creating sustainable communal spaces that redefine urban living in a mixed-use environment.
5 key facts about this project
01
A twisting building form maximizes light and views while minimizing solar heat gain.
02
Fifteen distinct segments create an engaging vertical landscape with varied experiences.
03
Landscaped terraces serve as communal areas, integrating nature within the urban fabric.
04
The design incorporates a high-performance curtain wall system for energy efficiency.
05
Direct access to an existing subway station enhances urban connectivity and public transport use.
Aqua Spina is a mixed-use architectural project located in Southern Downtown Singapore, reaching 1,500 feet in height. The design integrates residential, commercial, and community spaces, reflecting a harmonious connection with the site's waterfront context. The name Aqua Spina denotes a significant relationship with water, both as a geographical marker and a conceptual influence. This project aims to enhance urban living by cultivating a vibrant community atmosphere while addressing modern urban challenges.

The building's physical form is characterized by a dual structure that separates various programmatic elements. Each of the fifteen segments that comprise the southern blocks are designed to facilitate movement and interaction among users. A central feature of the design is "The Twist," a dynamic architectural element that introduces visual interest and maximizes natural light throughout the building. The implementation of a high-performance curtain wall system enhances energy efficiency while providing unobstructed views of the surrounding bay.

Sustainability is a cornerstone of Aqua Spina’s architectural strategy. The project incorporates multiple landscaped terraces, which not only serve as green spaces for community engagement but also contribute to environmental goals by improving air quality and providing habitat for local wildlife. Access to these areas is seamlessly integrated into the overall design to encourage public use, further enhancing the connection between residents and the natural landscape.

Innovative Design Approaches

Aqua Spina distinguishes itself from conventional high-rise developments through its unique approach to form and functionality. The twisting morphology transcends standard verticality, creating a sculptural silhouette that interacts with the skyline and environmental elements. The decision to include outdoor terraces emphasizes the importance of green architecture, offering spaces where community members can gather, socialize, and inhabit the vertical dimensions of the project.

In addition, the careful selection of materials—such as glass, concrete, and steel—plays a critical role in establishing both structural integrity and visual cohesion. These materials have been chosen not only for their aesthetic qualities but also for their performance characteristics that support the project's sustainability goals.

Architectural Detailing and Community Integration

Detailed architectural elements within Aqua Spina contribute to its functionality and user experience. The varied configurations of spaces create a sense of scale and diversity that caters to a wide range of activities, from residential living to retail experiences. The building’s design emphasizes accessibility, featuring a direct connection to the existing subway system, which facilitates movement and promotes public transport use.

The development prioritizes community interaction through its thoughtfully designed public spaces. Outdoor terraces equipped with seating and greenery invite residents and visitors to engage with the environment, further reinforcing the project’s dedication to enhancing urban life. This focus on community-oriented design encourages social interaction, transforming Aqua Spina into a vibrant hub within the urban fabric.

For those interested in exploring Aqua Spina further, the project presentation includes detailed architectural plans, architectural sections, and architectural designs that provide additional insights into the innovative ideas driving this architectural endeavor.
