GROUP HOUSING INTRODUCTION :

Group Housing means a group of houses for dwelling purposes and may comprise all or any of the following, namely:  A dwelling unit;  Open spaces intended for recreation and ventilation;  Roads, paths, sewers, drains, water-supply and ancillary installations, street lighting and other amenities; or  Convenient shopping place, schools, community hall or other amenities for common use;

In an apartment building, the spaces themselves must be single and universal enough to adopt a variety of lifestyles. As far as the movement through the apartment is concerned far more specific criteria can be established relying on basic circulation patterns that are valid for most living conditions. A well-planned apartment provides maximum privacy for various activities and makes movement to any room possible without crossing another. To achieve above various types of circulation, which govern the planning are to be kept in mind.

TYPES OF MULTI-STORIED HOUSING Simplex apartment The simplex is an apartment that has all Its room on one level • Both the living and sleeping activity occur on the same level • The close proximity of two activities, however may disturbing if they are not properly zoned • Major criticism for simplex has been the excessive amount of floor area required in corridors or stairs in order to gain access to the apartment •

THE DUPLEX APARTMENT The duplex is an apartment that is located on two levels • Living room, kitchen, and dining area on one level & sleeping area on the other level connected by an interior staircase • The major economic advantage is the elimination of a corridor & elevator doors on every other floor

TRIPLEX APARTMENT The triplex apartment located on three different levels • Living room, kitchen, and dining area on lower level & sleeping area on the upper levels connected by an interior staircase • This is restricted in high-rise apartment buildings it is supported in the private luxury-type buildings

A. TYPES OF GROUP HOUSING: 1. ROW HOUSING

Row house is, as the name suggests, one of many houses in a row. The style is mostly found in densely populated urban areas, where space is limited.

The row house style has flourished for various reasons. For one, as cities grew, space became an issue.

Construction methods and financial benefits also contributed to the popularity of row houses, which have been around since the 1600s. Row houses allowed builders to easily create homes, since they built several of them at one time.

2. CLUSTER HOUSING Cluster housing refers to a development in which homes are situated in groupings relatively close together, while larger areas of open space within the development form a buffer with adjacent land uses. Often this is accomplished through small individual lots, with the remainder of the land becoming common ground

SCHEMES FOR AFFORDABLE GROUP HOUSING IN INDIA. •

Pradhan Mantri Awas Yojana (PMAY) PMAY was launched in 2015 with the goal to provide 20 million housing units to the homeless by March 2022. At the end of its first phase, more than 1 crore such houses were already constructed and allotted to beneficiaries.

PMAY is divided into two parts, namely – • PMAY Urban • PMAY Gramin As the names of these schemes suggest, the former aims at helping urban residents acquire proper housing. The PMAY Gramin scheme, on the other hand, is concerned with providing affordable housing solutions to rural area residents.

SOME OTHER SCHEMES ARE : .

•DDA Housing Scheme.

•Rajiv Awas Yojana.

•NTR Housing Scheme.

•Tamil Nadu Housing Board Scheme.

•MHADA Lottery Scheme.

LIG Housing: People belonging to the low-income group households that are capable of making a gross annual income of rupees 3 to 6 lakhs are categorised under this sub-heading.

NBC GUIDELINES FOR RESIDENTIAL COMPLEXES/BUILDINGS. RESIDENTIAL USE ZONE :Good planning practice for designs of residential areas should include:• Light and air in the building • Protection against noise, dust and local hazards; • Open space for various family needs; • Easy circulation and access, safety from accidents; • As far as possible regular shape of plots; and • A logical arrangement of residential plots by size and shapes.The translation of these requirements into actual planning practice would vary with design relation and density patterns.

PLOT COVERAGE SHOULD BE AS FOLLOWS:

The minimum area of plotted development within jurisdiction of urban local bodies shall be 5 acre and it shall be 4000 Sq. meter in case of Group Housing and commercial use. However, development norms of local Body in terms of set-backs, parking, height, ground coverage, FAR etc. shall be applicable.
