Cartagena Spain
The Auditorium and Palace of Congresss in Cartagena sits along the maritime
façade of the city 200 m long. It is constituted of different volumes of different sizes
situated next to each other like big industrial containers. The different
spaces use different colours and this is highlighted by the colour used on the
façade.
You enter the building in the extreme
west of the volume and from here a descending
passage begins in which you lose the reference of which level you are on from
the exterior. There is a white space with orange benches. The natural light
passes through a double layered system of clear acrylic panels in which they
have longitudinal lines of colour in their extrusion (to be seen next).
The
building goes further down which eliminates the distraction and relation to the
exterior

Below the
ground level the structure is made entirely out of reinforced concrete. From
above this, nearly all of the other structural elements are metallic. The slabs
only have one line of central support which are made of a big metallic profile.
Above this is a composite slab. So the pillars along the facades are seen as
little as possible between the translucent façade, they are set in two supports
each with three metallic tubes in them.
The two layers of the façade are fixed to light lattice work which are put
vertically in between the pillars. There is a camera between the two layers
which acts as a thermal mattress.

The
metal pillars of the façade are the part most taken care of of the
whole design. They are 80 x 22 cm in profile and up to 9.4m in height and they
have to be as least present as possible.
Extruded Acrylic Slats Polycarbonate Tubes Aluminium Profiles
The building has three different outer skins depending on
the amount of light required, the interior spatial effect and the function of
each space.
These extruded acrylic slats make up most
of the façade and the interior finishes. Each of
the sections were specifically designed by the architects. There are two
different types of pieces, A and B and they can be put in two different
positions. They are either white or coloured in blue with different lines of
different colours and tones extruded in the slats. This colour is inserted at
the time of extrusion.
Transparent
units of these slats are used in the two layers of the façade and on the
interior spaces they are white.
In
the main auditorium, they have put these slats in shades of blue and green with
some vinil
strips stuck on to it to give an aquatic atmosphere.
Whole
system
The
façade of the other Auditorium is constructed by an industrialized system of
free standing sheets of galvanized steel filled with rock wool.
To
this support is fixed the special pieces of vertical substructure which is
stainless steel cut by laser on top of which the polycarbonate tubes with
different colours cover the exterior.

The
triangular profile of aluminium constitutes the west façade. The Urban Artist
Spy was the author of the design in the façade that marks the access and the
beginning of the sloped passage.
