2. 1 Objective of the
design
Flexibility
2. Public Realm
To evolve a framework within which a progressive development can occur with ease and efficiency.
The public realm embraces the external places in our townshipe which is accessible to all
Feasibility
2.
To ensure development within a given legal fiscal and organisational framework in a realistic time frame.
Site planning
Indigenous built for suitable lifestyles Indigenous built form provide a setting for a continuation of fundamental values of the society. From the clues of Indian cities and towns, the level of the publicness and the degree of privacy are maintained through a spatial order.
2. 2 Key Design
Strategies
1. Movement The majo strategy of community was to develop/ enhance walkability.and develop a friendly neighborhood with pedestrian activity. creating pause points, with community facilities.
3.Central Core The major public facilities are centred to the development creating a central core(heart) of the community, and the community spine being the lung spaces of the community. 4. Mixed Use + Density By taking the present growth trends of urbanisation and density, the key of any sustainable habitat is achieved by developing an mixed use development.

Vehicular movement Pedestrian movement
5. Identity Housing the housing development does blend with the exisitng built fabic, the identity is generated with the help of making spaces more legible, and with a people friendly public spaces
2. 3 Key Design
principles
1. Universal access The design ensures the access to the differently able people. The street ensures ramps at the junctions and other required places , tactile paving along the foot paths and other major public pathways. 2 unit in each block are designed for the specially challenged, the toilets , door width are changed designed in order suit their requirements, about 5% of the total units are of differently able friendly units.
6. people centric design To create an dwelling where ever dweller can enjoy the space. share - care- grow. so the design lies in defining space which are people centric, rather than ecnomic centric.
3.Pedestrian friendly environment The movement design in the site ensures a safety environment for the pedestrians, Dedicated walkways are provided on the either side of the road, the inner plazas and the main community spine do not allow the vehicular movement in it, The shaded walkways ensures a safe walking environment for the people.
4.Work-Live concept 2. Women & children Safety The Spaces are designed in such way that , they don’t end up any dead zones, all the areas are activated with lots of different activities, the community spines assure a safer walking pathways for the women, the concept of Eyes on the street is explored with active spaces like mix-use buildings along main road and balconies along the internal roads are designed to ensure the safety of women and children
The housing neighborhood ensures the coexistence of the work place and the living spaces as the housing community is located far away from the town, the provision of mix-use typology, shopping centre, skill development centres helps in training and running of businesses within the neighborhood. the skill development centre helps in empowerment of the women.

Principals
Design ideology indian-ism(indian urbanism)
01| Vaastu ancient indian science(science of orientation and placement)
Using the traditional indian house module, the multi-usability (flexibility) of a house, which is seen in an traditional indian house, where the space is used for several activities, a living space becomes a dining & kitchen, a bed room at night.
In keeping with the people’s desire for a strictly Vastu compliant houses, the placement of spaces in the house are in synch with the plan of the Vastu Purusha Mandala (the ancient Indian science of orientation and placement).Thus apart from positioning the main areas of the house according to the elements.
So the influences are seen in the space modulation, where there is privacy, yet creating a visual balance in the coherent living space. the sketch explains the detail of how we modulated in privacy of certain spaces with its shared spaces and influences of building materials and components like doors windows etc.
02| passive cooling techniques openess as the indian From the influences of many housing, our design has unobstructed cross ventilation paths. the orientation of the building does give the advantage in the space being shaded, and the uniform open spaces between the building creates a breating room to the buildings.
03| common wall use of common wall helps us providing a shared wall, which can reduce the building cost parameters, and also has the below strengths
04|introvert and extrovert towards openspaces Through the intro-extrovert spaces, we wanted to enhance the livability of each of the unit ,by making these spaces openable to public greens, enhancing the house opening towards these open spaces
05| Use of solar power Solar panels can be used to generate a portion of your home’s power in order to reduce your dependency on traditional power sources.

3.5 Construction
technologies
combination of both conventional and precast techniques for construction Conventional method of construction is used economical but it needs the time for concrete to get its strength.Meanwhile the shuttering should be removed after 21 days for beams of slabs.so to minimize this time we can replace only slabs or slabs of beams with the conventional columns & beams number of hollow core slabs. which can be directly layed as per the alignment of the drawing in very short time avoiding the time required for providing of shuttering and removal of shuttering . with this method we can really saves the time for casting of slab so the construction of conventional & pre cast method can be implement to save time & to cut the cost of the structure keeping the structure more stable and durable.
Rain water drainage and harvesting system -Rainwater colleccted from rooftop of each building by PVC pipes. - Harvesting pit provided ateach building , ove flow external rainwater channel. - Rainwater channel provided along the all roads , Harvesting pits provided at roads required areas to harvest the maximum rain-water.
Sanitary system
water supply and distribution system
1) Sewage drainage collected by underground piping system. 2) Sewage is connected to sewage treatment plant by underground piping system. 3) Sewage is connected to sewage treatment plant by underground piping and providing manholes at constant intervals. 4) sewage treatment plant provided at the suitable location , Although the this system is costly but we can use the recycled water coming from stop to external gardening & flushing , as the environment concerns it the best system to use.
1) Elevatedwater tank constructed at the highest level of site. 2) Underground water piping laid to each house to feed the water. 3) HDPE piping shall be used as the cost is economic. 4) This system shall be planned in economic way reduce the cost as much as possible.
Solar system for street lighting and housing 1) Although the initial cost of the system shall be costly compared to general system ,it repays the cost of electricity in long run. 2) The system shall be planned in economic way to reduce the cost as much as possible
concstruction details of built structure Foundation- Reinforced Concrete roofing , Cast in situ. Structural Members: Reinforced Concrete Plinth Beams, Pre cast Cement Concrete filler slabs with 40 grade mix by supporting beams of RCC M70 mix (RMC). The structural Beams will support the Roof Slab Passses as shown in diagram. where the spans will be sub divided into 1200x3000mm .
Floor screeding Screeding a floor is the sinmple act of applying a well blendedd mixture of ordinary portland cement with graded agregates and water to a floor base , in order to form a sturdy sub - floor that is capable of taking on the final floor finish or act as afinal wearing surface.
