While trees across Bengaluru fall during heavy monsoon storms, this engineer’s 600-sq-ft rooftop forest of 100+ fruits, vegetables and medicinal plants stands strong

Every monsoon, heavy rain and strong winds leave a visible mark across Bengaluru. Roads get waterlogged, drains overflow, and thousands of trees and branches fall across the city. Yet the top of a five-storey home, a 600-square-foot rooftop forest continues to thrive, reports The Better India.

Created by mechanical engineer Venkataraman, this dense green space is home to more than 100 varieties of fruits, vegetables and medicinal plants. Coffee, vanilla, cherries, dragon fruit, drumstick trees, pepper vines and native greens grow together in a carefully designed ecosystem that behaves much like a natural forest.


For Venkataraman, the terrace is more than a garden and is a demonstration of how nature can become stronger when different elements work together as one system.

Built to behave like a forest, not a collection of pots

According to Venkataraman, the real strength of the terrace lies beneath the surface. The rooftop was never designed as a group of separate potted plants. Instead, it was planned to mimic the way a forest functions naturally.

“The strength of a forest lies underground,” he explained Better India. “Roots connect with one another. They support each other and create stability.”

That underground network became especially important during periods of intense rainfall and strong winds.

“Take the drumstick tree, for instance. Its roots had woven themselves around neighbouring plants, locking into a shared system. Instead of standing alone against strong winds, the plants held each other in place”, he explains.

This interconnected root structure, commonly found in natural forests, helped the rooftop ecosystem remain stable even during severe weather.

More than a garden: A rooftop that works like urban infrastructure

While the terrace produces fresh food, its role extends far beyond gardening. The rooftop yields nearly two kilograms of coffee beans and supports a variety of medicinal plants, vegetables and fruit-bearing species. It also attracts pollinators such as butterflies and bees while providing a resting space for birds.

One of its most significant functions, however, is water management.

Nearly 80 percent of the rainwater that falls on the terrace is harvested, filtered and reused. Instead of flowing rapidly into stormwater drains, rainwater is absorbed and retained within the ecosystem.

This helps reduce runoff while making better use of a resource that is often wasted during heavy downpours.

According to Venkataraman, the terrace also creates a noticeable cooling effect.

He said the rooftop forest lowers temperatures in the surrounding area by three to four degrees Celsius and improves air quality by around 10 to 12 percent.

A tribute to his mother that became a larger experiment

The idea for the rooftop forest began on a deeply personal note. What started as a tribute to Venkataraman's mother gradually evolved into a long-term experiment exploring how urban spaces could support biodiversity and environmental resilience.

The concept was not immediately welcomed. Architects initially advised against building a forest-like ecosystem on a rooftop, citing concerns about maintenance challenges and structural safety.

Rather than abandoning the idea, Venkataraman approached the project from an engineering perspective.

He carefully studied load-bearing capacities, planned water management systems and developed practical solutions to make the concept work safely. Years later, the terrace has transformed into a thriving ecosystem that continues to grow and adapt.

Can Bengaluru's rooftops become mini forests?

Venkataraman believes that the rooftops across Bengaluru hold enormous untapped potential.

Instead of serving only as spaces for water tanks, storage or solar panels, rooftops can help cool buildings, harvest rainwater, support pollinators and improve biodiversity in densely populated neighbourhoods.

His terrace forest offers a glimpse into what is possible when urban design takes inspiration from nature.

By borrowing the logic of a forest—where plants, roots, water and wildlife work together—unused rooftops can become productive green spaces that benefit both people and the environment.

As Bengaluru continues to face rising temperatures, rapid urbanisation and increasingly intense monsoon seasons, solutions like these may prove that some of the city's most valuable green spaces are waiting to be created above ground.
