CONDITIONS:
§ a small triangular area
§ 100 m2 of building
capacity
§ a conspicuous, even though not
valuable, presence of trees
§
a
strongly reduced investment possibility
§ a client who balances his life
between Italia and Africa, where he deals with active cooperation
This leads to the idea of interbreeding the performance characteristics
and the intrinsic qualities of Western buildings with the craftiness and
simplicity (and thus the cheapness) of African ones.
A self-building system is chosen, though it’s a high performance one,
especially under energetic aspects
PROGRAM:
§ the choice of a simple, light
and cheap technology: wood. Fir laminated timber beams and OSB panels
§ the trees (with their shadow,
and thus coolness) generate the house geometry, which remains anyway simple and
Cartesian
§ the methods with which roots
are cutted and looked after establish the proximity of the building to the
greenery which surrounds and covers it
§ the falling of the leaves on
the building determines the roof geometry
§ gutters can’t be used
§ the exact position of the
broad-leaved trees determines the place of the windows in order to obtain
shading in summer and a positive greenhouse effect in winter
§ the adopted materials are
reduced so as to avoid to teach the client how to work with new technologies
TECHNOLOGIES:
§ a brick-blocks structure
conceived as two counterposed C constitutes the spine of the house and ensures
its earthquake-proof performances
§ the copper covering envelopes
the whole building defining the interface with the contiguous vegetation
§ the structural frames, made of
laminated timber beams, fit their pace on the panels dimension; less waste,
more saving
§ the glazed surfaces use the
vertical beams in place of the window frames, with the help of structural silicone
glue and glass clamps
§ the winter thermal response is
optimized by a combination of a programmable fireplace with forced airflow
exchanger, together with a continuous thermal insulation realized with a
ventilated reflecting mattress, used in aerospace engineering (there’s anyway,
in reserve, a more traditional methane boiler combined with a radiant floor
heat panels system)
§ the ‘Rothoblaas’ patent permits
to joint all the pieces of the timber structure with simple patented screws
Project drawings look closer to
IKEA instructions rather than classic working ones.
The most powerful screwdriver
available is bought on e-bay.
The works begin.
