A
large
number
of
these
unique
buildings
are
designed
by
architects
who
specialise
in
creating
original
styles,
and
will
draw
attention
to
the
finished
buildings.
Sometimes,
the
owner
of
a
building
wants
to
highlight
a
particular
way
of
life.
Some
buildings
represent
a
product
that
a
company
is
trying
to
sell.
On
other
occasions,
the
design
of
a
building
simply
makes
people
want
to
visit
it,
to
view
its
special
features
and
to
learn
something
about
the
person
who
created
it.
The
Forest
Spiral
in
Darmstadt,
Germany,
is
an

building.
