horizontal and vertical

circulation spaces

halls-corridors-stairs

ABALI TB I 2

• A space with a main activity is a node.

• All the paths connecting them are

circulation spaces.

ABALI TB I 3

• In public buildings circulation spaces are

specially important.

– Monumental entrance halls,

– Fluid corridors,

– Impressive stair cases....,

ABALI TB I 4

• A university building

entrance hall

ABALI TB I 5

In domestic scale

• for reasons of economy, we try to minimize circulation spaces

• however as “spaces of all users” they deserve to have a quality of its own.

• quality is achieved with ample dimensions and natural light

ABALI TB I 6

• Entrance hall in

domestic scale yet

with ample

dimentions

ABALI TB I 7

• In aparment flats

entrance halls are

minimal in

dimentions and no

natural light at all.

ABALI TB I 8

Same is true for corridors

• Our traditional

homes did not have

corridors

• A gallerie

overlooking to inner

court, a hayat was

the circulation

space.

ABALI TB I 9

• A corridor is by

nature a boring

space,

• It is linear,

monotonous and

usually have no

natural light

ABALI TB I 10

• To over come its negative qualities

– We have to keep circulation spaces at

minimum

– sometimes we overlap a space for certain

activity with circulation (a corridor to bedrooms cutting

through living room)

ABALI TB I 11

a corridor behind the

columns and a gallery

above the columns are

connecting to other

spaces yet it is zone

within main living area

ABALI TB I 12

• if we have to stay in minimum dimensions

than what are the possibilities ?

• usually number of doors opening to the

circulation area determine the size.

ABALI TB I 13

ABALI TB I 14

ABALI TB I 15

cupboards in the rooms or in the corridors are also effective in the size of

the corridor

ABALI TB I 16

in some period of the life span of a dwelling unit one user may be using

wheel chair....

ABALI TB I 17

• it is wise to keep the corridors 110 cm wide

and doors not less than 90 cm for

handicapped use in the long run.

• however, if a staircase is included than the

corridors may have different alternatives.

Landing at the end of a stair case

ABALI TB I 19

ABALI TB I 20

ABALI TB I 21

stairs

are not only for ascending and

descending

from level to level

ABALI TB I 22

• stairs gives us chance to perceive spaces

from many different views

• stairs create a space of their own

• stairs are circulation areas where 3 rd

dimention is most important.

ABALI TB I 23

Dutch artist

the concept

of “Relativity”

ABALI TB I 25

• Did you ever

climb to a

minaret ?

• This is stone

masonry

stair

ABALI TB I 27

Louvre

Museum,

Cristal

Pyranid,

Paris

ABALI TB I 28

• These are all monumental scaled stairs, in

domestic scale, we usually use efficient

and minimal stairs

• Therefore, it is vital for architects to make

best use of stair cases.

• To be able to do this, we have to master

technical issues of stairs.

ABALI TB I 29

slope of ramps – stairs - ladders

ABALI TB I 30

• The steepest stair,

ladder

• Only for young and

athletic ....

ABALI TB I 31

• Space under the

stairs have multiple

uses

ABALI TB I 32

slope gives us number of steps, let's say 16 steps

than comes how we arrange them

ABALI TB I 33

note that area they require do not change much
