Low Cost Housing is a concept which deals with effective budgeting and following of techniques which help in reducing the construction cost through the use of locally available materials along with improved skills and technology without sacrificing the strength, performance and life of the structure. There is huge misconception that low cost housing is suitable for only substandard works and they are constructed by utilizing cheap building materials of low quality. The fact is that low cost housing is done by proper management of resources.
Rajkot is the fourth largest city in the state of Gujarat, India.
The City of Rajkot is popularly known as a place with combined modernity and tradition
The notified Rajkot Urban Development Area is carved out of one district and 5 talukas -Rajkot, Padadhari, lodika, kotdasangani and Tankara from Rajkot District. From the boundary of RUDA there are 3 urban centers (Municipalities) namely Jamnagar in the north westerns part, Bhavagar to the southeast and Junagadh in the east.
The site is located in a sanctioned town planning scheme area of Rajkot with residential area surrounding it. The site is apt for this type of housing, considering the surroundings are of the same genre and the immediate surroundings are villages and amenities which would support the sustenance of a colony residing there.
GHB (Gujarat Housing Board) intends to propose a state of the art Residential Development in various cities of Gujarat to trigger a spark of economic growth in the entire state. Aim is to revive the Socio- Economic conditions by encouraging development in the housing sector (in harmony with nature).
The site is Located in a Sectioned TP Scheme no 16 of RUDA (Rajkot Urban Development Authority). Final Plot no is 31/A of 22517 sq.mt Area in total. Landform is flat without any level difference or any other hurdles. Site is aborting roads from two sides, where one is major TP road of 15 mt wide.
The main Urban Design concept is to introduce a Green Ecological Infrastructure. It will house two type of infrastructure facility: Green infrastructure & Red Infrastructure
DEVELOPMENT OF MASTER PLAN
Each cluster of population is oriented towards Green space.
For the central green concept the typology is derived from the same. Through the development of typology it was finalized that vertical core is kept in the periphery and amenities shall be placed in proximity to the green area.
As per the calculated numbers, the density for the site is 930/2.25 ha. But the ground cover is only 30% (as per GDCR), so the the typology should be a vertical one.
Master Plan :
After the Development process and open space concept, the cluster was designed as per the figure. Repeating the same cluster typology, the master plan is designed in 3 different clusters with one EWS and two LIG Housing Clusters.
Peripheral Movement pattern and Central green in-between the built mass with vertical core at the outer side will make easy movement.
The strategy is the central green nucleus, moreover the green nucleus is complimented with the greens sprawled in the periphery and the typologies of plants used are the same, to have and maintain harmony throughout.
Development of typology
Process takes the precedence of open space which should be well connected with built spaces, thus the circulation throughout should be up to the mark and it should ensure social interaction. The main axis and the secondary axis leading to the units which are bordered with open spaces.
Circulation and Orientation
The pedestrian access & the vehicular access are the governing factors of the circulation. These two factors are essentially approach roads to the open spaces which are flocked within the built space units. The main objective is to give people the possibility of various spaces where they can have a different social experience and where they can enhance their social interaction.
The massing is quite straightforward. There is an exterior bracket which withholds all the levels within, for the access, there are cores placed on the periphery so that the proximity to these is easier. The cores are also placed closely to the other social amenities which are further oriented towards the green section. Thus essentially most aspects are designed around the green space.
The footprint of the entire housing complex takes up about 55% of the space, which is a good amount of space acquisition instead of going more horizontal, the blocks are vertical to maintain that balance which we need between the green and the built space. Thus holistically the amount of space that is taken up by the footprint is appropriate to the site.
Parking and Roads
The parking and the roads are also closely oriented with the same logic and principle, which is to remain in close proximity with the block and the open green space. The space also has a definitive network which should complement the orientation and the direction of the blocks.
The building heights are varied and vary due to the typology of housing that it is. Thus the buildings which cater to a larger number are more vertical in nature, another factor which governs are the shadow patterns and the density aspect. The taller a structure is the denser it seems, thus buildings with varied heights not only provide us with a play in levels but also a complex which doesn’t seem dense in nature.
The services are strategically placed with close proximity to both, the approach roads and the periphery to have easy access for maintenance. Furthermore the services are placed at locations which are easily accessed by all units.
The various public amenities are placed close to the pedestrian network, and the approach zones. The amenities are dispersed all over the site, evenly to ensure access to all. The spaces around the amenities become gathering spaces which foster social interaction and hence become useful public nodes.
Thus to conclude one can see how the presence of design regulation and restrictions have been used to a certain degree of advantage. The units have been maximized in terms of utility and space utilization.
Furthermore the creation of interior gathering spaces, the landscaped elements, the green pastures, and communal zones which bring about a societal feel to the whole space, fosters communal interaction and ensures pockets of well allocated spaces.
