ULH URBAN LAKE HOUSING

ANCIENT WISDOM, RATHER COSMIC
So-shu dreamed,
And having dreamed that he was a bird, a bee and a
butterfly,
He was uncertain why he should try to feel anything
else,
Hence his contentment.
Ezra Pound, 1915
The urban refurfishment of Largo
San Giorgio site in Pordenone, Italy follows the main topic of returning the
citizens of Pondenone again a part of the town which was inaccessible due to
the different levels of the streets and to the fact that it had been private
for many years.
A path sews together the lake,
the park and the square of San Giorgio church designing a public open space
where the new housing and the church servces face.
As many of C+S works the
architectural design focuses on the strong relationship between architecture
and landscape.
The buildings mould themselves
with the lake boundaries and their elevations are designed by big wood-made
windows which both reflect the landscape and bring it inside the houses’
sitting-rooms.
The buildings design two sides
of San Gorgio square which is open to the town during the day and closed for
security reasons in the night thanks to a metal gate which folds on when not
used.
The skirting board of the
buildings is made of Prun stone, the same material which the square is made of.
The plaster surfaces of the
buildings, light grey and light ochre coloured, is on the same flush of the
stone and, as an effect of the buildings’ folds, one couldn’t easily tell
whether the slight differences of the chromatic effetcts are those of a colour
or simply of the shadow.
The buildings grow with the levels of the paths
surrounding the lake designing a new urban connection whcih specifically
changes material: Prun stone on the square, larch wood on the bridges crossing
the lake and ochre concrete on the paths of the park.
The path following the lake
leaves the earth and jumps in the water with a metal structure suspended on
sloping metal pillars.
The volumes facing the square host the spaces of
the church services.
Detailed architectural design
defines also the other public parts of the buildings: entrance halls and public
stairs, which are made of red-coloured wood, the auditorium (partially dag in
the ground), with grey and red acoustic panels, the church classrooms which are
graphically designed, All these spaces are naturally enlighted and look the
marvellous landscape of the lake outside.
All the houses are opened to the
lake with large wood-made windows and sliding wood panels to darken the spaces
inside.
C+S design has always a very
deep attention to sustainability. All materials used are ususally specific of
the site where the project is found and all buildings are studied for
low-carbon emissions.
In this case, the lake itself is
not only the expression of the landscape of Pordenone, which is a very
beautiful small hystorical town in the Northeast of Italy, built on the
boundaries of the river Noncello,
but it becomes also the energetic structure to make the complex work. ULH is
designed with a innovative heating and cooling system of pumps exchanging with
the different temperature of the lake.
In this sense the lake itself
becomes the main character of the architectural design as it is the background
of the new urban scenography, the new liquid soil where to walk over and
finally an energetic resource for the buildings’ functioning.
