A Climate-Responsive Office Tower by Sanjay Puri Architects

Sanjay Puri Architects design a 14-level office tower with semicircular decks, aluminum louvers, and integrated greenery to reduce heat gain.

Located in Nagpur, Stella rises from a compact 836.07-square-meter plot to deliver 5,575 square meters of office space across 14 levels. Designed for Prestige Builders and completed in January 2026, the G+14 structure accommodates four offices per floor within a vertical configuration shaped by site constraints and statutory open space requirements. The project responds directly to limited land availability while maintaining daylight access and natural ventilation throughout.

TOWERS

Nagpur records summer temperatures reaching 48°C, placing climate at the forefront of the design strategy. Sanjay Puri Architects conceived the façade as a layered environmental filter. Semicircular open decks alternate along the building’s perimeter, interspersed with planters wrapped in aluminum louvers. This arrangement operates both horizontally and vertically, forming a dynamic outer skin that reduces direct solar heat gain. The greenery integrated into the envelope introduces shaded zones and supports cooler microclimates adjacent to interior spaces.

Green buffers extend across the façade, enhancing thermal performance and improving visual comfort. The design positions the service and circulation core along the eastern edge, freeing the north, west, and south façades for naturally lit workspaces. Larger office units occupy the front and rear, capturing daylight, cross ventilation, and views. This spatial arrangement strengthens occupant comfort through passive environmental control rather than reliance on mechanical systems alone.

The project rejects the fully glazed office model common in contemporary commercial buildings, particularly unsuitable for tropical climates. Instead, Stella adopts a contextual approach rooted in climatic realities. The façade’s louvers and planted decks filter sunlight, reducing glare and internal heat buildup. Indirect daylight penetrates work areas, producing well-illuminated interiors protected from excessive solar exposure. These strategies collectively lower operational energy demand and promote long-term efficiency.

With a project cost of 20 Crores INR and a total built area of approximately 60,000 square feet, Stella establishes a high-density commercial building that aligns architectural expression with environmental performance.
