2 Story Iconic House Design near Negombo

This two story iconic elongated shaped massive house has designed with  unique aesthetic features.There are two main edges of the house and each edge has a large propped cantilever type feature, which is a huge portion of the house is supported by only one small sized column. A 13 feet long cantilever part has designed beyond the isolated column and on the top of that feature cladding has done with glass to view the entire surroundings. Under that huge propped cantilever part Green Grass Lawns are supposed to be built.

The unique architectural design was done by Architect:Gihan Karunanayake and the Structural Design was done by the Charted structural design engineer, Isuru S. Amarasena.

The foundation was designed with isolated pad foundations and random rubble masonry wall bases and 9"x9" tie beams with 4 number of T12 reinforcement bars. As the building is somewhat closer to the coastal area, ensuring the behavior of the building as a large single mas was very important as it can be lead to differential settlements.

In order to design the large cantilever and propped cantilever parts 9"x16" sized beams with several number of T16 bars were needed and some special type cantilever isolated stepped staircase design was used to impress the architectural features.Special consideration calculations needed to be done for the lateral stability of the building and the frictional drift as it has a narrow strip type shape. Cracking of glass cladding on cantilever slab parts also needed to be taken in to account as they can cause larger deflections.
