Grade-I Grade-II Grade-III
(A) Definition
Heritage Grade-I
comprises buildings
and precincts of
national or historic
importance, embodying
excellence in
architectural style,
design, technology and
material usage and/or
aesthetics; they may be
associated with a great
historic event,
personality, movement
or institution. They
have been and are the
prime landmarks of the
region.
All natural sites shall fall
within Grade-I.
Heritage Grade-II (A&B)
comprises of buildings and
precincts of regional or local
importance possessing
special architectural or
aesthetic merit, or cultural or
historical significance though
of a lower scale than Heritage
Grade-I. They are local
landmarks, which contribute
to the image and identity of
the region. They may be the
work of master craftsmen or
may be models of proportion
and ornamentation or
designed to suit a particular
climate.
Heritage Grade-III
comprises building and
precincts of importance for
townscape; that evoke
architectural, aesthetic, or
sociological interest though
not as much as in Heritage
Grade-II. These contribute
to determine the character of
the locality and can be
representative of lifestyle of
a particular community or
region and may also be
distinguished by setting, or
special character of the
façade and uniformity of
height, width and scale
(B) Objective:
Heritage Grade-I richly
deserves careful
preservation
Heritage Grade-II deserves
intelligent conservation.
Heritage Grade-II deserves
intelligent conservation
(though on a lesser scale
than Grade-II and special
protection to unique features
and attributes).
(C) Scope for Changes:
No interventions be
permitted either on exterior
or interior of the heritage
building or natural features
unless it is necessary in the
interest of strengthening and
prolonging the life of the
buildings/or precincts or any
part or features thereof. For
this purpose, absolutely
essential and minimum
changes would be allowed
and they must be in
conformity with the
original.
Grade-II(A): Internal changes
and adaptive re-use may by
and large be allowed but
subject to strict scrutiny.
Care would be taken to
ensure the conservation of all
special aspects for which it is
included in Heritage Grade-
II.
Grade-II(B): In addition to
the above, extension or
additional building in the
same plot or compound could
in certain circumstances, be
allowed provided that the
extension / additional
building is in harmony with
(and does not detract from)
the existing heritage
building(s) or precincts
especially in terms of height
and façade.
Internal changes and
adaptive re-use may by and
large be allowed. Changes
can include extensions and
additional buildings in the
same plot or compound.
However, any changes
should be such that they are
in harmony with and should
be such that they do not
detract from the existing
heritage building/precinct
(D) Procedure:
Development permission for
the changes would be given
on the advice of the
Heritage Conservation
Committee
Development permission for
the changes would be given
on the advice of the Heritage
Conservation Committee.
Development permission for
changes should be given on
the advice of the Heritage
Conservation Committee.
