Top-Down & Up, method of construction is the construction method in which after completion of one storey, at the same time continues to build to the lowest and the highest floor.

In Croatia this method was first used in the construction of residential and commercial building “Cvjetni” which has six underground floors and seven above ground floors.

Construction was started with level -1 after finishing diafragma wall and piles. With this method of construction, the building time has been reduced to about 4 months and therefore the price of the underground part of the building wa also about 30% cheaper.
