House near Bad Tolz
Fink + Jocher, Munich

Thomas Jocher
Erected within a period of nine months
with prefabricated timber elements, this
two-storey, low-energy house reflects
the vernacular of the local farm buildings
through the use of a few simple details.
The transparent areas in the north facade
were kept to a minimum in order to
reduce energy losses. To avoid extremes
of temperature, sliding shutters with louvres
set at different angles were installed
for the large areas of glazing in the south,
west and east faces.
The timber stud walls were based on the
American balloon-frame system, using
full-height elements with continuous verti-

cal members. The walls are in a two-skin
form of construction and are braced by
the internal plywood lining. The inner leaf,
in which the mechanical services are
housed, bears the loads from the floor,
which stops short of the vapour barrier.
This ensured a simple assembly of the
house and a safe, airtight construction. The
wall is insulated with a total thickness of
22 cm cellulose fibre. The problem of noise
transmission via the continuous vertical
studs was reduced by building the inner
leaf of the wall with horizontal members.
The floor is in a simple, hand-nailed vertically
stacked plank construction. The
advantage of this system is that it allows
the use of cheaper off cut products. The
floor also has great rigidity, with a structural
depth comparable to that of a reinforced
concrete slab. No chemical preservatives
were used for the wall, floor or
roof timbers. ty DETAIL 1/1998
