PROJECT DESCRIPTION A,

'r-A

This project is the proposed new combined residential, office and holel development in Tripoli libya. The building will consist of 3 main towers circular on plan linked at the base by a podium retail space. The main towers are clad in an aluminium and glass curtain wall with a large glass podium area at ground level. The curtain wall on the main tower will wrap around the building with a small section of glass wall cover at the lift area. At the roof, the curtain wall will continue past the roof in a spiral affect.

Q

The podium levels will have fixed glazing and the restaurants and lobbies will be clad with point fixed glazing with glass fins.
