Pillai College of
Cluster Development also known as conservation development is a
site planning approach that is an alternative to conventional
subdivision development. It is a practice of Low Impact Development
that groups residential properties in a proposed subdivision closer
together in order to utilize the rest of the land for open space,
recreation or agriculture. Cluster development differs from a planned
unit development (PUD) due the fact that a PUD contains a mix of
residential, commercial, industrial, or other uses, whereas the cluster
development primarily focuses on residential area.
The purpose of cluster development is to:
The primary purpose is to create more area for open space,
recreation and more social interaction.
Promote integrated site design that is considerate to the natural
features and topography
Encourage saving costs on infrastructure and maintenance through
practices such as decreasing the area that needs to be paved and the
decreasing distance that utilities need to be run
Provide for better uses of the land than those produced through the
narrower standards provided in the regular zoning classifications;
Offer greater protection and buffering to environmentally sensitive
areas and desired open spaces.
The benefits of cluster development as opposed to a convention
More preserved land for open/recreational space
A better setting for community building
Possible local agriculture production
An optimal arrangement in storm water management

Cluster housing: Great plan, but even greater
Naresh Kamath, Hindustan Times Mumbai, March 04, 2013
Five years after it was mooted with the view of changing the face of this bustling metropolis, only five proposals have been
cleared under the cluster redevelopment project. Of these, work has begun only in two projects; the others continue to wait
for various clearances.
Aimed at holistic development and integrated townships, the cluster scheme is meant for big redevelopment projects where
the area to be redeveloped is a minimum of one acre. While the state, the civic body and experts say it is a good scheme as it
ensures adequate open spaces and plans decent amenities for residents, the project has not gone very far. The biggest issue
is government delay, say developers.
“There is policy paralysis with regard to the cluster scheme,” said Pranav Merchant, vice-president and director of Shreepati
Group, which has five cluster projects awaiting nod since 2009. “The tenants are restless and all we are giving them are
assurances that work will start soon.”
Unlike other redevelopment projects where only the Brihanmumbai Municipal Corporation (BMC) needs to grant sanctions,
the cluster scheme also requires a nod from the state’s urban development department (UDD). After that, a builder must get
all relevant civic permissions.
Developers complain that files get struck in the UDD. BR Bhattad, director, Bhattad Group, is still awaiting the go-ahead from
UDD for his 12-acre project at Sewri. “They have been looking at my project since 2009,” he said.
Another problem is with regard to consent from tenants and landlords. The scheme requires 70% of tenants and 100% of
landlords to give their consent, which builders say is tough. Take the case of the Saifee Burhani Upliftment Project, which
covers 16.5 acres in Bhendi Bazaar. Some landlords have refused to give consent for the revamp. Local legislator Amin Patel,
who supports the project, said: “We can’t let a few elements derail the scheme. If 90% people decide to go ahead, the rest
should be forced to do so.”
“This is the best revamp scheme till date, but the government should offer more incentives to make it attractive,” said
Nishant Agarwal, managing director, Nish Developers, which is the only cluster project where construction is going on. “As of
now, individual redevelopments are more attractive for builders.”
Sachin Ahir, minister of state for housing, admits the scheme has not many takers and accepted that the UDD has been
delaying projects. “We want to decentralise permissions so people don’t have to come to Mantralaya,” he said, adding that
the state is reviewing the scheme. “A committee of secretaries is studying the scheme. We will incorporate changes
Cluster redevelopment policy amended,
skyscrapers can now go up to 80 storeys
Written by Shalini Nair | Mumbai | Posted: September 10, 2014 1:00 am
From facilitating purchase of public plots and buildings and acquisition of land from non-consenting residents living in
run-down buildings to offering substantial floor-space index (FSI) to developers, the state government’s amended
cluster redevelopment policy, issued on Tuesday, has a host of incentives for developers taking up such schemes in south
The incentives in the amended rules would effectively transform several existing low-rise settlements in the island city
into high-density zones with skyscrapers as high as 60 to 80 storeys. The state government issued the final notification
for the policy in the run up to the imposition of the election code of conduct this week. The decision to extend the
scheme to the suburbs has been kept in abeyance for now due to a court mandated stay on increasing the FSI through
such schemes without studying its impact on infrastructure. However, after initial hesitation, the state approved the
incentives for island city where cluster policy for redevelopment of old tenanted properties over an acre area has been in
force since 2009.
“We were planning on filing a civil application in the Bombay High Court to seek its permission to go ahead with the
amended scheme in the island city. However, the advocate general advised us that since the scheme has been in force
there, it would be fine to go ahead with the amendment,” said a senior state government official. The final notification,
however, comes with a rider that the hike in FSI allowed under the new policy would be subject to the court’s orders.
Under the amended policy, developers taking up redevelopment of clusters of buildings in the island city will get an FSI
of four or higher. A minimum FSI of four allows builders to construct a built-up area that is at least four times as much
as the size of the plot. Developers can construct premium residential projects on the plot by consuming FSI that is as
high as 55 to 100 per cent of the FSI used to rehabilitate the existing residents. The 2009 policy has been modified to
allow tenants who own large houses to get an equivalent portion for free. The same would be true in case of owning
huge commercial properties and opting to go for residential properties post-redevelopment. In such cases, developers
get to consume a proportionate amount of FSI on this additional area. Earlier, in both cases, if the existing area exceeded
100 sq m, the residents had to purchase the additional area at the construction cost, thus, eliminating the incentive FSI
component for developers.
The amended policy also allows a state government-appointed empowered committee to acquire 30 per cent of land
from non-consenting residents and hand it over to developers if buildings on such land are declared to be in a
dangerous state provided the developer has the consent of the remaining 70 per cent.
Maharashtra to Revise Cluster

MUMBAI: The Maharashtra Government will soon revise its cluster housing policy for the
development of old and dilapidated buildings and other complexes, Minister for Housing and Slum
Development Sachin Ahir said here on Friday, adding that the State also plans to set up a real
estate regulator by August 15 to protect the rights of the property buyers.
“The (existing) cluster policy is not working well. The new policy aims at creating 40-50 new
clusters. We will also set up a high-powered committee to grant single window clearance for
housing projects,” Ahir said.
Under the cluster housing policy, buildings older than 30 years and having at least 10,000 square
metres of land can be brought down to make way for new buildings if at least 70 per cent of the
residents decide so.
Under a new proposal, the government will have the right to acquire an area by giving adequate
compensation to the residents.

Developers may benefit because these designs usually reduce the
costs of site development and increase the market price of individual
plots in comparison with traditional subdivisions.
These designs can benefit rural areas by reinforcing the policy of
maintaining the local rural character that is included in many
comprehensive land use plans
Local officials, developers, and the community may be predisposed
toward traditional development designs because they are familiar and
well understood. An education effort may be necessary to help these
groups understand the goals and advantages of cluster development.
During the planning phases, lot and home layout may take extra
work to ensure that while homes are located closer together, they still
take advantage of the open-space goals of the design.
Methods to protect and maintain the open space must be carefully
developed, implemented, and monitored.
In conventional planning there is no consideration for natural features ,topography
It has narrower roads and tighter lots.

Preserved open space may be included as a portion of one or more
large lots, or may be contained in a separate open space lot.
The Cluster Development concept saves open space by putting the
same number of houses on smaller lots.
