Altair, the 69-story luxury residential complex which fronts Beira Lake in Colombo, celebrated its "topping out” to mark the completion of structural work. Going back to ancient times, the topping out ceremony marks the milestone of the placement of the last structural steel beam at the final roof height. This important moment also celebrates the accomplishment of the structural construction crews and the transition to interior construction.
Altair is composed of two slender tower blocks, with one block leaning into the other vertical tower, which supports it. The towers are oriented to the movement of the sun and to harness the tropical breezes, and the units offer 270-degree views of Beira Lake and the Indian Ocean. The unique diagrid structural system accentuates the slope of the inclined stepped tower.
“It is very exciting to see the completed building form tapering elegantly toward the sky. The unique combination of a straight and a sloping stepped tower gives the building a very distinctive appearance and has become a landmark for locals and tourists,” said Charu Kokate, who visits the site regularly. The diagrid structure is highly rationalized and allows for naturally ventilated and beautifully lit units. The units are very private and with their special entrances are like “little houses in the sky”.
A generous allocation of space for public areas, a feature of high-end buildings, is even more evident in this building. Of Altair’s 1.5 million square feet of space, 828,000 square feet or 55 per cent is residential space. Of the balance, 36,000 square feet is allocated for retail while 636,000 square feet, or 42.5 per cent is public space.
The 400-unit towers offer spectacular views of the Beira Lake, the Indian Ocean and the city of Colombo. The building is scheduled for completion in July 2018 and is already 70 per cent sold.
