Text description provided by architect.
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 openings 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
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.
