ARCHITECTURAL GUIDELINES FOR THE SOUTHEAST COASTAL PROVINCES

Siting

• Site buildings on high ground to preserve

wetlands, capture breezes, avoid insects,

and provide potable well water.

• Locate buildings at the edges of clearings

to capture breezes and shade.

climate, retaining ventilation

• Separate functions into connected or related

buildings.

• Clear vegetation around buildings for ventilation

and to protect from insects and fire.

• Place hard surfaces (“aprons”) around the

bases of buildings to minimize mud splash.

MASSING AND SCALE

• Use simple geometry and forms.

• Make buildings more vertical, with smaller

footprints, to catch breezes and to promote

ventilation.

• Add simple forms when expanding.

• Connect buildings through covered breezeways.

• Subtract volumes from the perimeter to

create breezeways (as in a dogtrot house).

• Use slender framing and exposed structure

to promote a “light” appearance.

ROOF

Roof elements include the roof itself,

overhangs (eaves), dormers, skylights, and

other features that penetrate the roof.

• Use simple roof forms such as shed, gable,

or hipped.

• Minimize intersections of these forms that

create “valleys” that can cause leaks.

• Design roof pitches to range from 7:12 to

12:12.

• Use broad overhangs to provide protection

from sun and rain.

• Avoid gutters, but include a dripline trench

of gravel or cobbles.

• Make gable-style dormers from simple

forms to provide ventilation and light

without complicating the roofline.

sun and driving rain

BASE

• Coastal buildings should sit very lightly on

the land.

• Walls can meet the ground without a base.

• Basements are often not suitable.

• Lower Piedmont buildings may include bases

made from a different material from the siding.

WALLS

• Expose or plaster brick walls with stucco

or “tabby” (a mixture of lime, sand, and

oyster shells).

• Use horizontal wood siding, as with lap siding.

a horizontal expression

WINDOWS AND OPENINGS

• Create a welcoming entrance that conveys a

sense of arrival (for example, with a porch).

• Create porches either by extending the roof

or by subtracting wall space.

• Provide good ventilation with traditional side

porches.

• Use larger window openings for public buildings.

• Use sidelights to provide visual access and

to daylight the entry.

• Install operable windows when possible.

• Screen windows and doors.

• Avoid heat-trapping fixed panes in dormers

or gables.

• Remove obstructions (such as vegetation)

in front of windows.

• Create lintels that can be expressed rather

than flush to the wall.

• Make shutters functional, such as louvered

shutters that block the sun while providing

ventilation.

• Encourage cross-ventilation by placing louvered

vents or windows directly across from each other.

STRUCTURE

• Expose post and beam and other structure

when suitable. Exposing structure reduces

the volume of building materials needed.

• Use small-dimension posts and beams to

create structures that appear to be light

and airy.

• Use lighter, relatively narrow structures

and materials to complement the tall,

slender trees found in coastal forests.

• Minimize cladding that creates cavities

that can trap moisture and insects.

MATERIALS

• Use natural, indigenous, or locally produced

materials when possible.

• Select durable, low-maintenance materials.

• Express local craft and artistry in public

buildings.

• Use synthetic materials that resemble natural

materials, are durable, and match the ROS

setting.

• Use metal roofs in areas where they were used

historically.

• Use materials that yield horizontal expression,

such as clapboard siding.

COLOR

• Derive color schemes from native vegetation,

landforms, and local culture.

• Create a color scheme to be used throughout

a forest. Use darker colors within the forest

canopy and lighter colors in open, sunny areas.

• Construct light-colored buildings that reflect

heat and stay cooler.

• Use bright accent colors that can be derived

from flowers, lichens, or cultural influences.

• Make roof colors light but nonreflective.

• Use light colors for exposed structural

elements (posts, beams, and trusses) so they

do not appear “heavy.”

• Light grays and tans of tree bark

and sands

• Greens of palm and pine

• Accents in the pastels, corals and

• Red clay of the Lower Piedmont
