(1) Roof Treatment. Roof treatment should reflect existing roofscape by using combinations of overhanging
eaves and pitches greater than 1:3. Roofing materials should be green or reddish earth-toned tile or gray slate
roofing surfaces, or roofing surfaces which closely resemble existing tile or slate roof in color, texture and
appearance.
(2) Architectural Style. Architectural elements to be encouraged are the open design of arcades, porches,
entryways, internal pedestrian spaces and courtyards. New developments should be influenced by the following
architectural styles: modified Mediterranean, Spanish mission, Victorian, U.S. Greek revival, Italianate revival,
and French second empire.
(3) Facade. Facade elements common to the precinct include recessed window openings and strong horizontal
lines expressed by combinations of fenestrations, openings, wall edges and decorations. New development should
incorporate and employ these elements to visually relate new buildings to adjacent facades of established historic
value. Typical is the use of projections, columns, balconies and recessed openings.
(4) Color and Surface.
(A) Colors and surfaces in the precinct are characterized by being absorptive rather than reflective. The use of
shiny metal or reflective surfaces, including paints and smooth or plastic-like surfaces should be avoided. Colors
and surfaces which predominate include warm white walls, earth tones, natural colors of stone, coral and cast
concrete. Concrete, stone, terra cotta, plaster and wood should be principal finish materials.
(B) If the use of metal surfaces is required, they should be used with black or dark earth-toned matte finishes.
Copper and brass may be acceptable metal surfaces. Glass surfaces, where used, should be recessed and clear, or
of light earth-toned tints.
(5) Texture. Characteristic textures include those of stucco, tile, concrete, cut coral, cut stone, cast iron, grass
and foliage. Development should employ surface qualities which are sympathetic to historic and original uses of
material.
(6) Details.
(A) Details are of prime interest and importance at the pedestrian scale and constitute an important design
element. The use of terra cotta, plaster work, ironwork, ornament painting and sculptural elements is highly
encouraged.
(B) Respect for historic design including detailing should be maintained on elements such as pavers, curbs, signs,
planters, benches, trash cans, fountains, lighting, bus shelters and flag and utility poles.
(7) Entry Treatment. Characteristic of places within the precinct is the treatment of building entry which
provides comfortable transitions from outside to inside. These elements include arcades and porches recessed or
projecting from the building mass.
(8) Orientation. In order to protect mauka views within the precinct, new development should be oriented on a
mauka-makai axis.
(9) Signs. Signs shall not be directly illuminated, have moving parts, luminous paints or reflective materials.
Any illumination should be from a detached source shielded from direct view. No box fluorescent signs shall be
allowed.
(10) Landscape Treatment.
(A) Large open spaces, lawns and canopy-type shade trees, fountains and sculptures shall be compatible with the
grounds of Iolani Palace and the Capitol building.
(B) In small open areas, combinations of ground covers, shrub masses, flowering trees and palms may be used
either to introduce rich foliage patterns, for screening purposes, or to provide contrast to large, open lawn areas.
(C) Small-scale landscape features such as courtyards, resting places, entrances and intimate gardens are
encouraged and should be compatible with, and secondary to, the larger park-like landscape.
(c) Design Guidelines for Other Precincts.
(1) Open Space. All parcels shall comply with the minimum open space expressed as a percentage of lot area
designated on Exhibit 21-9.1, set out at the end of this article.
(2) Visual Impacts. All major development, especially on those parcels and building facades visible and adjacent
to the historic precinct, shall be reviewed to ensure that new structures do not visually intrude into the historic
precinct. Articulated building walls are encouraged. The use of recessed windows, lanais, projecting eyebrows,
offsets in the wall planes and exterior colors may be used to achieve this articulation.
(d) Height Regulations.
(1) Heights for all precincts are identified on Exhibit 21-9.1, set out at the end of this article.
(2) The director may exempt the following architectural features from the height regulations of the Hawaii
capital special district, provided they are erected only to such height as is necessary to accomplish the purpose for
which they serve, but in no case exceeding 12 feet above the maximum height limit. These building elements may
