Following four years of design and construction, Mumbai-based design studio Sanjay Puri Architects recently completed Stellar, a solar-powered commercial building in Ahmedabad, India. The building features a striking sculptural office on its northwest side. Constructed with rust-red colored aluminum sheets, the angular office is a focal point for not only the 110-meter-long building but also for the bustling intersection where the building is located. To mitigate the city’s temperatures, which rise to an excess of 95 degrees Fahrenheit for eight months of the year, Stellar features a series of terraces that deflect solar gain.

Spanning an area of 18,580 square meters, the multistory building houses retail on its lower three levels and office spaces on the upper four levels. About one-third of the offices open onto landscaped terraces and are set back from the building perimeter to take advantage of solar shading. The terraces are connected to a rainwater harvesting tank that stores runoff for reuse. Solar panels have also been installed on the terraces to harness renewable energy.

The crowning distinction of Stellar is the 500-square-meter office on the building’s northwest side. Surrounded by a spacious, north-facing outdoor terrace, the eye-catching office is wrapped in angular aluminum sheets strategically placed to protect the windows from the sun. Small triangular perforations along the sides of select panels also allow natural light to pass through into the office during the day and are backlit at night to give the office a beautiful, glowing effect.

“This office space is deliberately designed to contrast with the rest of the building, creating an interesting juxtaposition of color, volume and geometry in addition to creating an individual identity based upon the brief,” the architects explained. “The simple rectilinear geometry with muted color tones and the complex angular geometry awash with color contrast to create a unique composition.”
