Helical Tower Embracing Natural Ventilation with Glass and Steel Elements

Project in-detail

Emerging as a helical structure of glass and steel, the tower enhances natural ventilation while maximizing urban connectivity, serving as a mixed-use space that integrates workplaces and community areas.
5 key facts about this project
01
Helical form enhances visual dynamic and spatial efficiency.
02
Diagrid construction allows for structural flexibility and reduced material use.
03
Natural ventilation optimizes energy performance and occupant comfort.
04
Integrated green terraces promote biodiversity in an urban setting.
05
Strategically oriented openings maximize daylight and city views.
Vórtice is a 60-story architectural project situated on the western banks of the Pinheiros River in São Paulo, Brazil. This tower merges innovative design with functional requirements, embodying both aesthetic and technical considerations. Its primary function is to serve as a mixed-use development, intended for office spaces and public activities. The building's distinct helical form not only enhances its visual appeal but also facilitates efficient space utilization and energy performance.

The design concept of Vórtice is characterized by its fluid, dynamic structure that symbolizes growth and motion, reflecting the vibrancy of its urban context. The tower's orientation maximizes views of notable landmarks, such as Jaraguá Peak, while strategically placing openings for natural light and ventilation. This interaction with its surroundings demonstrates a commitment to integrating architecture with the environment.

Unique Structural Features
The Vórtice project employs a helical design that distinguishes it from typical high-rise developments. The spiraling form allows for increased floor space without excessive material usage, utilizing a diagrid steel structure for strength and flexibility. The building's core supports the outer layers in a way that promotes a sense of openness, creating balconies and terraces that foster interaction with the environment.

This innovative geometry addresses both structural challenges and the need for a sustainable design. The incorporation of advanced materials—including concrete, glass, and steel—ensures that the building is both durable and visually appealing. Furthermore, the façade is designed to manage solar exposure effectively, contributing to reduced energy consumption and enhancing occupant comfort.

Sustainability and Urban Integration
Vórtice also reflects a strong commitment to sustainability with various passive design strategies. The orientation of the building minimizes heat gain, while overhangs and external shading devices provide ventilation and thermal comfort. Landscaping elements are integrated into the design, promoting biodiversity and enhancing the surrounding public areas.

The positioning of entrances and pathways facilitates pedestrian accessibility, connecting the tower to nearby parks and public spaces. This integration reinforces the idea of community engagement and fosters an urban environment that is both functional and inviting.

The details provide a comprehensive understanding of the design methodologies and innovative approaches that define this significant contribution to São Paulo’s architectural landscape.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
