MYCC architects: prefabricated nature

built in three months and assembled in three days, ‘prefabricated nature’ is a vacation house
by spanish firm MYCC architects (formed by carmina casajuana, beatriz g. casares
and marcos gonzález), located in the galician municipality of cedeira, spain.

the house is located on a steep slope, in a remote location in the northeast corner of the iberian
peninsula, an area dominated by the imposing presence of the ocean and the forest of eucalyptus
trees surrounding it. the terrain is surrounded by harvest fields, family farms and pitched roof
houses. this image, protected by the area’s building codes, determined the geometry of the house.



the volume was wrapped with two materials with the purpose of setting up a dialogue with
the landscape. the roof and the side facades were covered with viroc®, a prefabricated mixture
of cement and wood shavings. the fibercement has a great strength efficiency in spite of being light
and, therefore, is easy to maintain and move. the two main facades of the house were clad with
perforated corten trays following the schematized image of a forest silhouette, recreating the image
of the surrounding vegetation. this material was chosen because it is part of the local tradition
of fishing towns like cedeira, used for the construction of boat hulls, and the gradual and controlled
oxidation of which gives the material self-protecting qualities. its patina and changing color create
a lively image that relates with the natural environment. this interplay between the natural and
the artificial also benefits the interior spaces, where the light that crosses through these silhouettes
casts shadows of trees in the different rooms.



being a vacation house, the interior spaces are free-flowing and
open up to the landscape,
turning it into the protagonist. the
six modules that make up the house, of approximately 6 meters
in length
and 3 in width (the maximum reasonable width to enable their
transportation by trailer)
organize the program as follows: the first
one contains the bedroom, which can be divided into two
thanks to a
blind concealed in the ceiling, and which becomes a partition wall when
more rooms
are needed; the second contains the bathroom and stairs; the
third the kitchen; and the last three
the living room. the top floor,
under the roof flaps, houses an attic that is a free-flowing space with
a double facade that opens up to the sea views towards the southwest
and to the forest towards
the northeast. it is a space that flows out
onto the living room without a designated use, and that
can perform as
a guest bedroom, tai-chi room or playing area for kids.

the house combines two different systems: prefabricated construction
(2d) for the attic
and modular construction (3d) for the ground floor.
the modules were built in the facilities
of the construction company
idm in the madrid town of valdemoro. these modules were built
with a
structure of beams and galvanized steel columns and with floor and
ceiling slabs of
composite decking with reinforced concrete. the facade
walls are dovetail sandwich panels
formed of two sheets of lacquered
aluminum and an 80-millimeter-thick polyurethane web plate.
layers of waterproofing stretch beneath the furring strips to which the
exterior facades
are fixed. towards the interior, a ventilated air
cavity of 20 centimeters lets the structure go
through, and there is a
perimetral panelling of plasterboard with 46 millimeters of rock wool.

the result is a 30-centimeter-thick wall with a ventilated facade
cavity, interior cavity and 12
centimeters of total insulation. after
an assembly trial in the factory, and after making sure that
fit in properly, the different modules and trusses of the building were
taken apart
to be packed and moved in trailers the whole 700 kilometers
separating the factory from
the remote seaside site where its was to be
installed. all the parts were put together again on
the designated site
in just three days, and the finishing touch-ups were done in the
two weeks.
