Pro j e e te pe r a 1 a Di a g o na 1 Ens interessa un ripus de
consrrucci urbana la naruralesa de la qua! sigui arquirecronica i
que no depengui ni d'un pla general ni de prorot ipus d
'habirarges, sin
que emergeixi de la manera ms directa possible de les
circumsdlncies que la condicionen, que la
realirzen i que desprs l'expressen. Conseqentment, no veiem que
el conflicte de !'entramar de Cer-
da amb les diagonals, )'actual xarxa viaria i la manera actual
d'usar-los siguin un obstacle sin ms aviar un excellent desafiament
arquirectonic per contrarestar tant la latent fragmentaci com la
crea-
ci d'estereotips. Proposem un acord mnim:
l. Recreaci de la D iagonal en el seu concepte originari, amb
una avinguda de palmeres com a pas-
seig central, que creua el teixit del conjunt ci rcumdant i
segueix !'actual trac;at de carrers.
2. Subradlar elmodel d'illa de Cerda, amb un conjunt de blocs
periferics de 24 metres de profundi-tat i de quatre pisos d'alt,
amb botigues, diversions peral pblic i vestbuls d 'entrada als
blocs d'apar-
taments.
3. Els apartaments se situaran en torres per damunt deis edi
ficis de quatre pisos, amb la qua) cosa gaudiran d' una gran
quantitat de llum i ventilaci naturals. O n )'entramar esrigui
intacre, les torres estaran disposades ortogonalment, i deixaran
lliures les cantonades deis blocs, mentre que a prop
de les diagonals aquestes seran emfasitzades. A l llarg de les
diagonals, suggeri rem una alta densitat
que s'aniria reduint cap als marges exteriors. Les
imprescindibles superfcies per aparcar es distribuei-
xen sota terra. Els patis es conservaran com a oasis de pau i
tranquillitat, estaran protegirs deis so-
rolls del carrer per l'entorn del bloc i hi haura plantes.
4. Els apanaments sn, ms que res, moduls desenvolupats al
voltant d'amples hivernacles de doble
alc:ada que actuen com a zona d'esmorte"iment, tant pel que fa a
les temperatures com a les qestions
funcionals. El sal, la cu ina i la sala de bany poden
prolongar-se en l'hivernacle. Aquest pot assumir
funcions per a les quals no hi ha espai en els apartaments de
distribuci tradicional. Por utilitzar-se
com a cambra per practicar el bricolatge, com a estanc:a per
emmagatzemar coses o com a espai
per guardar les bicicletes i les planxes de surf: s una estanc:a
que satisfa les necessitats del ci utada
urba per expressar la seva posici individual i social. s per
aixo que els hivernacles disposen d'un sistema de persianes que
otorguen a l'edifici de maons, senzill pero digne, un caracter ms
ldic.
Sense reclui r el volum o la densitat const ruYes i superposant
idees tradicionals sobre l'espai urba a
les necessitats de la vida moderna, s' han crear les condicions
imprescindibles per al desenvolupa-
ment d'edificis residencials urbans.
La zona de la Diagonal en el seu estar actua l posseeix un forr
atracriu precisament perque exagera
la rigidesa de !'entramar de Cerda i perque els fragments d'
illa contenen inrrnsecament l'essencia
d'una arquitectura i d' un disseny urbans que no podem continuar
negant.

pro j e e t f o r La Di a g o na 1 We are interested in an urban
mode of bui ldi ng which is architectural in nature and is neither
dependent on a master plan nor on housing prorotypes, but which
emerges
in the most direct way possible from the circumstances
conditioning it, realizes their relevance, and
then expresses them. We therefore do not see the conflict of the
Cerda grid with t he diagonals, the
existing street network and the present use patterns as an
obstacle, but as an excellent architectural
chance t0 counteract both the latent fragmemisation and the
implicit stereotyping. We propase a
mm1mum agreement:
l. Re-creation of rhe Diagonal in its original profile with an
alley of palms as a central promenade,
cutting through the fabric of the surrounding development and
following the existing street pattern.
2. Underlining the Cerda block pattern with a 24-metre deep,
four-storey peri meter block develop-
mem with shops, public amenities, and emrance halls to the
apartmem blocks.
3. T he apartmems wi ll be in towers above the four-storey
buildings thus having optimum natural
lighting and ventilation. Where the grid is intact, the towers
will be in an orthogonal arrangemem,
the block corners will be left free, whilst in the vicinity of
the diagonal the corners will be em-
phasized. Along the diagonals we would suggest high density,
getting lower towards the outer edges.
The necessary parking spaces are provided underground. The
courtyards will be retained as oases
of peace and quiet; they are protected from street noise by the
block edge and will be landscaped.
4. The apartments themselves are main ly maisonettes and are
developed around spacious double-
height winrer gardens, which work as a buffer area both in terms
of climate and funct ion. The liv-
ing area, the kitchen and the bathroom can extend into the
winter garden. It can take on functions
for which there is no room in traditionally-organized
apartments, be it do-it-yourself room, a keep-
fi t room or storage space for bicycles and surfboards: but it
is also a room which accommodates
the need of the city-dweller to express his individuality and
social status. T he winter gardens therefore
have a system of blinds which gives the unpretentious but
earnest brick building a more playful
character. Without reducing the built volume or density, the
conditions necessary for the develop-
ment of urban residencial buildi ngs have been created by
superimposing tradicional ideas about ur-
ban space with modern living needs.
The Diagonal, area, in its present state, has great charm,
precisely because it exaggerates the rigidi-
ty of the Cerda grid and because the individuated block fragmem
s intrinsically contain the essence
of an architecture and an urban design which we can no longer
deny.
