Mossos
d’Esquadra Police Headquarters, Martorell
Volume
and general image
From
the exterior, the building is perceived as a volume made up of a
ground-floor base with two upper floors in the form of a
parallelepiped. The block housing the technical services is designed
as an annexe to the main volumes.
Where
the building overlooks Avinguda de les Mancomunitats comarcals, the
upper parallelepiped projects beyond the ground floor, forming an
eave that shelters the building’s entrance, creating a space of
transition between the street and the interior.
The
ground-floor base is dark-coloured quartzite. The upper volume has a
hard, massive finish on three sides, whereas the west façade
comprises a more generous, glazed plane with the addition of
adjustable vertical slats to provide protection from the afternoon
sun and as a security measure.
Description
of the project
Both
the urban implantation and the characteristics of the site suggest a
compact building that exploits the lengthwise geometry of the plot
and respects the planning determinants (maximum occupation and
regulatory distances from adjacent properties). The inherent security
requirements of the programme dictate this compactness.
Layout
The
building comprises a basement and three above-grade floors and is
laid out in keeping with the structural grid. Crosswise, the distance
between columns is 4.80 m; lengthwise, the two side bays are 4.80 m
wide, opposed to the 6 m of the central bay.
On
the basement floor, this arrangement produces a car park with a
central passage (6 m wide) with two side strips for parking (each
4.80 m deep).
On
the other floors, the six-metre bay houses service spaces and
circulations, whereas the 4.80-m bays accommodate offices and public
spaces.
Ground
floor
The
public area is in the building’s entrance, with an information desk
facing the door. One passage leads to the interview rooms, while
another provides access to other areas.
There
is a separate entrance for the Mossos facing the communications
shaft, which also provides direct communication between the public
and the restricted areas.
The
custody suite is situated at the far end of the site. Its
distribution repeats the logic of the public area, laying out custody
cells to one side and the remaining spaces to the other. Once again,
a two-corridor system separates circulations according to uses and
prevents overlapping. There is only one point of access from the
general distribution passage to the custody suite.
A
second communications shaft (stairs and lift) at the rear of the
building provides direct access from the car park.
The
custody suite and identification room act as a buffer between the
cells for minors and adults, allowing separate direct access from
both areas. They also allow visitor access without having to enter
the rest of the area. The detained persons arrive by patrol vehicle
and enter this buffer area via a metal security gate in the east
façade.
The
technical services are located in the third bay on the ground floor,
separate from the public area and custody suite, with their own
entrance from the exterior if needed.
First
floor
This
is where restricted activities take place. It comprises two bays: one
houses the communications shaft, services and auxiliary spaces, and
the other the offices. The entrance corridor is situated on the west
side, enjoying a degree of transparency and exploiting natural
lighting. The offices are situated in the east, with more discreet
openings to prevent visual proximity to the exterior.
Second
floor
This
floor holds the most private spaces, the police officers’ service
area.
The
layout is similar to that of the first floor. One bay contains the
entrance passage and services, and another houses staff spaces:
changing rooms to the north, dining room and rest areas to the south
(with views of the river Llobregat valley) and, at the centre, the
briefing room and a protected terrace that provides indirect lighting
for the hall and easy access to the exterior.
