Construction details
All the open space around the ground floor of the building not only allows the entry of natural light and fresh air inside, but also creates a basis for the extraordinary volume consisting of steel and glass façade is superior.
The main building was designed with linear forms, in a block located within a three-dimensional facade of steel and glass.

A service road is designed for ambulances, fire trucks and other vehicles in service in the west, south.
Interior
- Atrium
With an opposite character to the facade, the interior block is rectangular, thus, on the ground floor interior volume was obtained, the atrium. This space is between the wall and the inner block, is 12 meters high, is used as a large circulation area, also placed a lobby to the auditorium, a cafeteria and a semi-covered office.
- Block
The interior block has two wings, left and right, with a large central bridge.
On the ground floor is an auditorium, the cafeteria kitchen and service stairs. The upper floors have been sealed with a glass facade soundproofing of the possible noise from the atrium and also highlight its rectangular lines.
On the first floor, west wing, are the private offices of the minister and vice minister. The east wing offices were located open. On the second floor, open-plan offices were located in two wings. Two staircases allow access to the central bridge.
It has three fire stairs, a lift for use VIP and handicapped accessible.
Structure and Materials
We used concrete in the stairs to the basement patio in the retaining wall surrounding the building and the ground outside. The concrete used in the inner facade was painted.
Both the facade of the courtyard buried like the top of the building are made of steel and glass. To create a whole unit used similar colors and patterns on the windows of the facades of the building.
The main facade consists of a steel frame profiles 200 × 400mm, like most of the internal structural system of steel profiles and secondary structure 150x150mm. Profiles were also used Ø60mm circular steel, PVC and aluminum profiles for some window areas such as border area of the exterior facade.
- Composition facade
The facade is divided into three sections. The first is born at level 0, the second is the main facade and the third is the top of the front that connects to the roof slab, level 12.00. All sections of the facade have different angles and surfaces. The movement of these three variables in determining the characteristic facade of the building. At the same time, the facade is composed of 3567 triangular pieces of glass of which 1947 have different shapes and sizes.
Because natural ventilation is obtained within the atrium, as well as air-conditioning system, some modules of these triangles, both on the ground floor and the upper have been designed as windows that open synchronously by an automatic system.
The atrium was divided into four parts closed for five fire walls are made of steel and glass, to prevent, in case of fire, any leakage of smoke in different spaces of the building.
