a) Reasons for selection of the building:-As an Architect it is important to design a building which is costeffective yet functional in every aspect and reduces the

dependence on mechanical control measures which are resource

hungry.

That is the reason why I chose this building to study, because it

is constructed on the green building concept and uses the

resources for reducing the mechanical energy in the building. It

is a residential building.

Stage-II: Planning

a) Design concept: - The site for this residence is in South

Delhi, on a plot sandwiched between two existing houses. Thechallenge was to develop three separate apartment units of

approximately of 10,000 sq. ft. total built up area while ensuring

adequate light, ventilation and open, green spaces for all units.

A landscape courtyard was sculpted out of the earth towards the

south allowing the winter sun to penetrate into the living areas

while floor to ceiling glass allows the indoor spaces to flow out

into this green court. The building is designed as a load bearing

exposed brick structure with flat slabs. This makes theconstruction process simpler and faster while allowing for larger

volumes and an effortless aesthetic. The spaces are organized

along a linear gallery that's forms the spine of the building,

providing for efficient circulation as well as the zone through

which all services are carried and distributed.

b) Design considerations and restrictions:-1.

This Vasant Vihar residence has been designed as a multi-family

residence, comprising of two duplex apartments of 4,100 sq. ft.

each (Basement / Ground and Second / Third floors) and a single

floor apartment of 2,050 sq. ft. on the first floor. Located in a

rapidly densifying neighborhood, this project incorporates a

hybrid structural system - load bearing brick masonry walls

(achieving an appropriate response to the Zone 4 seismic code)

wrap the envelope on three sides, while a reinforced concrete

frame system anchors the core.

2. The project juxtaposes an open core concrete frame "tent",

within a perimeter mass of brick "caves". Hence, the thicker

brick walls with controlled apertures enclose the more private

bedroom and bathrooms, while the porous frame, infilled with

insulated glazing, enables the south-facing living and dining

areas to be illuminated by natural light all day.

3. The house projects an unadorned expression of its primary

structural materials. Most importantly, the skin is maintenancefree and permanent.



4. Vir.mueller architects worked with the brick masons on site to

create subtle shifts and offsets in the facade walls, enabling a

textured surface to emerge from the brick structure itself.

5. The deep window recesses in the elevation are highlighted by

staggering the bricks in the adjacent walls; conversely, the bathroom windows are veiled in a brick screen, exaggerating the

sculptural potential of the material on the facade.

6. As the brick wraps from the east facing front facade to the south

facing side, the load bearing walls transition to reveal the glass

clad concrete frame.

7. The entire south facade faces a stepped garden, descending from

the ground floor to the basement.

8.

The edge beams of the concrete are detailed to create drip edges,with a thin edge that frames a "necklace" of stainless steel - this

is actually a rainwater collection pipe, storing the water collected

from the terrace in an underground cistern.

9. The limestone floors in the interior are highly polished to reflect

light, contrasting against the exposed brick walls.

10. The pleated concrete stairs, floating in the double height volume

of the public rooms, have railings that are crafted in stainlesssteel pipe.

11. The electrical and air-conditioning services are routed in vertical

shafts located on the exterior walls, facilitating ease of

maintenance.

12. As children are being raised to develop sensory skills in

synchronicity with tablets, the vital link between the sheer

physicality of human interface with material in domestic space is

perhaps most critical.

13. In the chaos of a dense and cacophonous urban metropolis, the

volumes of this building - filled with light and patterned with

texture and shadow - seek to create a sense of wonder even

within the everyday confines of domestic space.



c) Floor wise Area statement:-

Plot area = 83' X 36' = 2985 sq ft.

Permissible F.A.R. = 250%Permissible Coverage on Ground Floor = 70% = 2089 sq ft.

- Basement = 2050 sq ft.

- Ground floor = 2050 sq ft.

- First floor = 2050 sq ft.

- Second floor = 2050 sq ft.

- Third floor = 2050 sq ft.

- Total covered area including basement = 10250 sq ft.

-

Total covered area excluding basement = 8200 sq ft.- F.A.R. achieved = 2.40

INNOVATION IN THIS

BUILDING Vir.mueller architects worked with

the brick masons on site to create

subtle shifts and offsets in the facade

walls, enabling a textured surface to

emerge from the brick structure itself.

The deep window recesses in the

elevation are highlighted by

staggering the bricks in the adjacentwalls; conversely, the bathroom



windows are veiled in a brick screen, exaggerating the sculptural

thumbnail of the material on the facade.

As the brick wraps from the east facing front facade to the south

facing side, the load bearing walls transition to reveal the glass clad

concrete frame.

The entire south facade faces a stepped garden, descending from the

ground floor to the basement.

The edge beams of the concrete are detailed to create drip edges,

with a thin edge that frames a "necklace" of stainless steel - this is

actually a rainwater collection pipe, storing the water collected from

the terrace in an underground cistern.

The residence in Vasant Vihar is a four floor town house in a dense

residential colony in New Delhi.

The design provides for a south facing linear court to allow for

maximum penetration of natural light.

It is a hybrid structure of load bearing exposed brick work and

R.C.C. columns with flat slabs.

A central gallery forms the spine of the building carrying all the

services and infrastructure for the apartments.

Brickwork is both structure and skin, yet not a single brick

was cut during the construction of the house.



Highly polished marble floors are the single luxurious

material, justified as a reflective surface that improves the

quality of natural light.

Brick screens and balconies act as a buffer zone,

tempering the effects of Delhi's intense climate.



Light delicately percolates through the brick screens

casting striated shadows around the interior

The bathroom uses marble as one of the luxurious

indulgence.



Different materials, brick, concrete, wood and marble all

fit well together.The limestone floors in the interior are highly polished to reflect light,

contrasting against the exposed brick walls. The pleated concrete

stairs, floating in the double height volume of the public rooms, have

railings that are crafted in stainless steel pipe. The electrical and air-

conditioning services are routed in vertical shafts located on the

exterior walls, facilitating ease of maintenance.



Stage-IV: CRITICAL ANALYSIS

(a) Analysis of site layout:-



Site is planned according to its surroundings and restrictions

of small plot size. Site is accessible through a access road on

one side and service road on back side.

Site is in rectangular shape and the building is designed in the

shape of extended rectangular.Trees are planted around the building especially for western

and southern exposures to conserve the energy required for

cooling the building.

(b) Analysis of space planning :-This Vasant Vihar residence has been designed as a multi-

family residence, comprising of two duplex apartments of

4,100 sq. ft. each (Basement / Ground and Second / Third

floors) and a single floor apartment of 2,050 sq. ft. on the first

floor. Located in a rapidly densifying neighborhood, this

project incorporates a hybrid structural system - load bearing

brick masonry walls (achieving an appropriate response to the

Zone 4 seismic code) wrap the envelope on three sides, while

a reinforced concrete frame system anchors the core.

The project juxtaposes an open core concrete frame "tent",

within a perimeter mass of brick "caves". Hence, the thicker

brick walls with controlled apertures enclose the more private

bedroom and bathrooms, while the porous frame, infilled with

insulated glazing, enables the south-facing living and dining

areas to be illuminated by natural light all day.

The house projects an unadorned expression of its primary

structural materials. Most importantly, the skin is

maintenance free and permanent.

(c)

Analysis of building features – structure,

services, etc. :-

This building constructed with exposed brickwork as

skeleton and skin.

In creating a house with locally available materials, and

crafted by regular construction workers, Vir.mueller



architects are asserting the primacy of regular

construction means and methods as the basis of a

contemporary design practice.

This residence establishes the primacy of habitation in

harmony with the environment, and an architecture

capable of identity without using high tech design

approach.

As the brick wraps from the east facing front facade to

the south facing side, the load bearing walls transition to

reveal the glass clad concrete frame.

The entire south facade faces a stepped garden,

descending from the ground floor to the basement.

The edge beams of the concrete are detailed to create

drip edges, with a thin edge that frames a "necklace" of

stainless steel - this is actually a rainwater collection

pipe, storing the water collected from the terrace in an

underground cistern.

The limestone floors in the interior are highly polished

to reflect light, contrasting against the exposed brick

walls. The pleated concrete stairs, floating in the double height

volume of the public rooms, have railings that are

crafted in stainless steel pipe.
