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

apartment

building.
