House for Ziphouse (www.ziphouse.se)
This
passive house was the continuation of the Ziphouse concept started with the
Line, Frame and Square Houses - to change the traditional outlook of low-cost
prefabs homes, focusing on modern designs, yet keeping the vital functions of
practical family living.
Through
formal languages not as closely inter-related as in the three precursors,
the foldings which has been
created in the other three are still used but more discretely in a new way out
of a more obviously monolithic volume.
A
white L-shaped tree box with a light sloping roof embraces two adjacent
terraces. These terraces are folded out as a continuation of a frame, acting sun
shields around two wide window areas, each with one integrated glass door. The
gap between the two terraces invites nature to touch the house at a piece of
black timber panelling which bisects the otherwise white facade. The one
terrace is a continuation of the diningarea by the kitchen while the other is
continuation of the living room, dividing the outdoor space into different
uses.
When
first approached, the house appears very discrete ? it consisting of a timber
terrace, a short white timber-clad facade with a centrated glass door and a
floor to roof window next to it, framed by a timber sun shield stretching out
over the facade, then running down and backwards again, creating a bench.
While
entering the house, one also
enters on an axis following a clear sight line ending with a full-height window in the living room at the far
end of the house. Following the axis from the entry, there are two bedrooms to
the left and a laundry and bathroom to the right, as well as a multi-functional
room as part of the corridor which can be used as a library, office or as a
space in which to install an integrated double-storey bed for guests. Next,
there is a crossway axis cutting through the one starting at the entry. This
continues through the kitchen with an installation wall on the one side and, on
the other, a bar disk looking out over the big social area with dining area and
living room. Counter-balanced on the main axis is the master bedroom and a
vista through a glass door at the end of the wall.
In
the two social areas, consisting of the dining area and living room, the
functions expand outwards on to the terraces, erasing the boundary between the interior and exterior.
Between the two parts of the social room, there is a wooden box projecting
outwards from the facade with an integrated window, making a niche on the
inside to sit or lying in, realxing or reading a book.
The
building utilizes a unique building system which is a refinement of the normal
SIP (Structural Insulated Panels) building method. It is 100% damp proof,
extremely air-tight, and well insulated making it one of the first prefabs certified according
to the Swedish Government?s strict regulations on passive housing. Combined
with highly efficient windows and foundations, the house does not require any
active heating, even when the temperature drops to -20�C.
