Spiral Form Inhabiting A Rainwater Harvesting System Enhanced by Concrete and Steel Elements

Project in-detail

A conical structure utilizes reinforced concrete and steel to create a symbiotic relationship with its mountainous environment, integrating rainwater harvesting and hydropower generation to serve as a sustainable community hub.
5 key facts about this project
01
Conical structure optimized for natural ventilation and energy efficiency.
02
Integrates an advanced rainwater harvesting system with substantial storage capacity.
03
Features extensive use of reinforced concrete and steel for enhanced durability.
04
Utilizes hydroelectric power generation from nearby water sources.
05
Incorporates communal terraces designed for local agricultural use.
The Energy Stepwell is an architectural design project situated in Meghalaya, India, that integrates sustainability and community engagement into its core functionality. The building serves multiple purposes, including energy production and water management, while creating a supportive environment for the local community. This initiative aims to produce renewable energy, manage water resources effectively, and establish communal spaces that facilitate social interactions.

Sustainability and innovative design are the hallmarks of this project. The structure employs advanced energy systems, notably hydroelectric power generation, which addresses local energy needs while minimizing environmental impact. Additionally, the design incorporates rainwater harvesting techniques, allowing for efficient collection and purification of rainwater. This approach not only conserves water but also reduces the building's reliance on external water sources.

The Energy Stepwell features distinct architectural elements that set it apart from conventional designs. One significant aspect is its spiral form that rises in a conical shape, resonating with the region's natural topography. This design optimizes natural cooling through strategic positioning and facilitates wind patterns, contributing to energy efficiency. The use of materials, including reinforced concrete and structural steel, ensures structural integrity while allowing for flexibility in the architectural framework. Large glass sections promote light penetration and foster a visual connection between occupants and the surrounding landscape.

The project is compartmentalized into functional layers that enhance its utility. The electricity storage layer accommodates renewable energy technology and integrates a sewage purification system that processes wastewater effectively. The hydropower generation component harnesses kinetic energy to produce electricity, completing an efficient energy loop within the building.

Furthermore, communal spaces are interwoven throughout the structure, promoting social interaction and local agriculture. This design philosophy fosters a sense of community among residents, emphasizing the well-being of its users alongside environmental considerations. The Energy Stepwell serves as a model for future architectural efforts aimed at addressing sustainability challenges through innovative design.

For individuals looking to understand the intricacies of the project, exploring the architectural plans, sections, and designs can offer deeper insights into its unique approaches and comprehensive functionalities. Delve into the architectural ideas that make the Energy Stepwell a noteworthy example of contemporary architecture.

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.
