Covering 3,00,000 sq. ft., the Motilal Oswal HQ is one of the brightest sparks of fresh, contemporary façade design in Mumbai’s bustling commercial district of Prabhadevi. Complete with modern, energy-efficient features, the financial services giants used 10,000 sq. ft. of glass for this façade design. The total cost of this project is estimated at Rs.150 cr.
Motilal Oswal wanted to maximize space available in their old six storied headquarter. The building needed to consolidate all corporate activities of the organization under one roof. The objective was to create a landmark structure that would symbolize their reputation in the financial sector.
The façade design intended to be chic and contemporary, yet not outspoken, a fair blend of modern trends and corporate sophistication.
Evolution of Design
The design evolved from various juxtapositions of the existing building and extended infrastructure requirement. It finally concluded on expansion of existing floor plates and additional six floors, wrapped together in a stunning glass façade.
Versatility with Glass
Glass was used extensively for the project; in fact the building is quite literally enveloped in glass. Most prominent areas of application included glass façade and skylights.
The façade design was conceived as a subtle glass envelope embraced with horizontal fins at regular intervals, alternatively also facilitating sun-shade. The paucity of space for break areas was compensated by sectional displacements of recreation zones vertically.
‘Sky-lounge’, an awe inspiring 5500 sq.ft. glass habitat with a height of nearly 80 ft., covered with glass above renders an uninterrupted sky-view. Laminated solar control glass is used for skylights.
Saint-Gobain recommended KT 440 – Nano Green for both the facades and skylights. Nano is a high performance glass that has a very low solar factor, and a low e value (high thermal insulation). It thus contributed to high energy efficiency of the building.
The building used ceramic frits extensively on the front side. The centre of the façade has been off-set inside in concave camber and clad with fretted glass, thus pausing the continuity of fins. Ceramic frits not only contributed to the aesthetic appeal of the building, but also added a huge value on the energy efficiency front.
Another very interesting feature of this building is that bent glass, in huge quantities, has been used for this structure. Bending a low e glass is a difficult and rare feature. Low e glass – SGG Nano Green – has been bent into a complete U shape, which made this building absolutely spectacular.
Other Green Features
The building hosts a stunning array of LED lighting. It makes the building’s façade design stand out like a sparkling jewel in the city of blinding lights, during the night time.
A terrace garden elevates the recreation experience on the sky lounge.
