Spatial planning of 10 Marla house

This portfolio consists of different assignments

and jobs which we did in our lectures given by SirSardar Arif. First of all, we were given a Plan of

two storey residential building. Our first

assignment was to rearrange the spatial plan

which is most suitable according to human

requirement.Plan was of nearly 10 Marla,

I.e. 65 * 35.

According to the given requirements and to fulfill

the basic necessity of ventilation, I made three

changes in spatial planning.

1)Decrease the area of drawing roomAs we know, we spend our most time in living

room and bed room. I decreased the area of

drawing room, making no spare spaces, so that

there will be room for patio against the dead

wall.

2)Increase length of patio and decrease widthto make living area larger better view of

landscaping from outside.

3)I have provided patio with the dead wallTo have natural light and cross ventilation in

dining room and kitchen I provided a patio of

8*10. This patio also opens against living room

providing natural light and ventilation. At the

first storey there is a bathroom attached to

bed room. There was no natural light and

ventilation before, but this patio provides

both.

Finding flaws and re-designing existing plan :

This is our first assignment in which we have to

design the spaces in most efficient way. We

were given a plan of existing building and find

flaws in it and then remove those flaws by re-

designing it. The building was two storey of

area 35 by 65.

Flaws in design:

1)There was no natural lighting and ventilationin bathroom at first storey. I have provided it

ventilation through ceiling as well.

2)Drawing room space was very large thatdining and living rooms got smaller

So I provided patio against the dead wall so

that proper lighting and ventilation is given

to bathroom attached to guest bedroom.And I scaled down the drawing room space

to make living room larger, as drawing room

is used occasionally but living room is used

most of tha day. We redesigned the plan and

drew it on autocad.

Integration of grid structure with non load bearing walls

In the Second assignment we were asked to make a grid structure and plan the spaces

accordingly.we were allowed to make changes in plan upto 20% means space was to be integrated

with the grid planning.


6/20

Integration of grid structure with non load bearing walls

So I made a grid plan having 6x6, 6x12 and

corner columns as shown below.

CORNER 6X12

6X6

COLUMNS

Corner columns were provided to avoid

differential damge. 6*12 columns were provided

in such a way that longer span becomes shorter to

avoid more moment.

I provided cross beams at couple of places where

there was no column for the beams to rest upon.

Cross beams are into each other thay can carry

load and transfer it to net column.

After those spaces were adjusted in a way that

beam does not destroy the aesthetic look.

Comparison of horizontal and vertical structural components

Horizontal structural members

1)Cavity wall2)Hollow core concrete block3)Earth compressed block

1)Reinforced brick concrete slab:It consists of reinforcement, brick and concrete. Bricks are laid horizontally between the steel bars and concrete mix is

inserted in the joints to fill the gap between bricks and for covering the reinforcement. The slab is supported on the wall and

the top surface of the slab is plastered with a 2cm thick cement mortar and over that apply two layers of hot bitumen for

water proofing. Over the bitumen coat apply one more coat of cement paste of thickness 5 cm.Provide sufficient slope at the

top surface for drainage of rainwater.

2)Reinforced cement concrete slab:In reinforced cement concrete slab sand, cement and aggregate are used in the ratio of 1:2:4. With reference of strength

R.C.C slab is more economical then R.B.C slab whereas R.B.C is easy to construct. In the following pages I have a comparison of

R.C.C and R.B.C slab with reference of cost.

3)Jack arch roof:It reveals from archival drawings and existing old buildings that the major components of Jack Arch roofing were Bricks for

construction of Segmental Arch, Steel Joists to support arches, Tie Rods at ends arches to keep the arch in its original

position and to address the problems of tensile stresses, Wall Plates and Nuts to make the connection of Tie Rods from itsboth ends. A Jack Arch roof is usually formed with number of 4.5 inches thick brick masonry segmental arch of 6-9 inches rise

from centre for 4 - 6 feet span supported by Rolled Steel Joist (RSJ) spanned over shorter dimension of room from wall to

wall. To make upper surface of roof as flat, the lime or cement concrete was used as filler in gaps. Above that the plaster layer

and subsequently the mud layer were usually provided.

-Cement bags = 51

-Sand = 120.11 cft

-Crush = 240.191 cft

Cost = 1, 07,864/-

For 5.5 Th. R.C.C Slab:

Cement bags: 100

Sand : 246.23 cft

ECO FRIENDLY EARTH BLOCKS:

Compressed earth blocks have following advantages:

They are cost effective and durable structural elements Easy to construct, made of natural soil and non toxic They provide a suitable indoor environment They are also known as green construction

Following plan shows the integration of earth compressed blocks with jack arch roofing


13/20

Fast construction with hollow core concrete blocks:

They are non load bearing walls with fast construction, cavity in these blocks provide better thermal condition and suitable

indoor environment. They do not need external or internal plastering. They can be used load bearing vertical components if

these holes are filled with reinforcement in form of vertical walls. The appropriate size of these blocks is 6x12x6.theyare cost effective and also used as fire resistant but they are not good for large spans. Some other advantages of hollow

concrete blocks are

Light in weight Services can run through their holes They are available in different sizes Acoustics transmission Thermal transmissionTo make these non load bearing blocks, load bearing walls we can provide reinforcement bars through the holes of block.

These blocks are represented in the following diagrams and plans.
