⯈ As of August 2014, the tower's construction reached the 90m milestone.
7. ⯈ Design & Functions
⯈ The design of this building is inspired by the Lotus flower. The lotus symbolizes purity within Sri Lankan culture,
and is also said to symbolize the country's flourishing development. The tower base is inspired by the lotus
throne and will also be formed by two inverted trapezoidal. The tower's colour is planned to alternate between
pink and light yellow by smooth transition- an effect achieved by coating the glass.
8. ⯈ The concept and preliminary design is by local architects. The Faculty of Architecture of the University of
Moratuwa provides the indigenous technical and architectural expertise. A team of consultants led by Emeritus
Professor Nimal de Silva, Professor Samita Manawadu and Professor Chitra Weddikkara of the Faculty of
Architecture, University of Moratuwa provides professional advice on this mega project.
⯈ The tower will be 350m tall and will be spread over 30,600 square metres floor area.
⯈ Lotus Tower's main revenue sources will be tourism and antenna leasing. Ťt will function as a radio and
television broadcasting antenna ŤSDB-T support
structure for 50 television services and 20 telecommunication service providers, and will house a variety of
tourist attractions.
9. ⯈ The tower will have 4 entrances, with two being used as VŤP (distinguished guests and state leaders) entrances. A
telecommunications museum and restaurant will be located on the ground floor. The tower podium will consist of
6 floors. The first floor of the podium will accommodate a museum and 2 exhibition halls. The second floor will
be utilized for several conference halls with seating space in excess of 400 people. Restaurants, supermarkets and
food courts will be situated in the 3rd floor. A 1000-seat auditorium will be located on the 4th floor, also used as a
ballroom. The fifth floor will include luxury hotel rooms, large ballrooms, with the seventh floor hosting an
observation gallery. The landscaping is planned in the form of a large water park.
⯈ Surmounted on the tower head, the mast will be the base for antennaes of TV, FM and telecommunication service
providers. According to the TRC these will be installed at a height of between 250 to 350 meters from the
ground level.
