ARCHITECTURAL GUIDELINES FOR THE ROCKY MOUNTAIN PROVINCE

SITING

• Locate structures at the edges of clearings.

• Place buildings on the south side of dense

vegetation or mountain slopes to ensure

adequate sun for heat and light.

• Use low vegetation on the north side to

anchor buildings to their sites.

MASSING AND SCALE

Mountain buildings and structures can be

dwarfed by the grandeur of the soaring forests

and rugged geological formations that surround

them. Mountain buildings set within overscaled

landscapes often include overscaled building

elements, such as oversized doors and windows,

heavy timber structures, and boulders incorporated

into the building base. Such elements help humans

relate to the overpowering scale of the landscape.

• Use simple, compact forms.

• Break up larger buildings with similarly

shaped smaller masses.

• Repeat simple forms.

• Use large-scale building materials

(such as boulders at the base) to

match the scale of the landscape.

ROOFS

Roofs should convey a strong sense of protection.

They typically dominate the architectural

composition.

• Echo topography with the roofline.

• Increase pitch as the site steepens or as

the forest becomes more vertical.

• Use alpine roofs with flatter pitch to avoid

snowshed problems.

• Avoid complex multiple roof forms such as

those that combine shed and gable dormers.

These create “valleys” that trap moisture

and cause maintenance problems.

• Provide broad overhangs at sites enclosed

by landforms or vegetation.

• Provide modest overhangs at exposed,

windy sites.

Figure of roof pitches varying with the verticality of landscape and the setting:

Broad valleys with a pitch of 4:12 to 9:12

Foothills with a roof pitch of 6:12 to 10:12

High mountains with a roof pitch 8:12 to 12:12

Alpine with a flatter roof pitch

 

BASE

The base functions as the transition from the

landform to the mid-wall, creating a sense

that the structure is growing out of the site.

• Anchor the building into the site with a

strong base.

• Use a uniform base on moderate slopes to

provide a platform for the building.

• Step the base on steep slopes or for large

buildings to match the forms and volumes

of the building.

Figures of buildings with an appropriate base:

·       Base that takes up the grade

·       A stepping stone base that responds to the grade

·       A stepping base on steep slope

·       Base can “grow” out of the stone outcroppings

·       A weathering base in snow with slight batter to stone and larger stones at the bottom

MOUNTAIN

WALLS

Walls can appear to be thick and substantial,

with heavy corners. Emphasize corners through:

• Using larger materials.

• Making them solid—avoid placing windows

and other openings in the corners.

WINDOWS AND OPENINGS

• Concentrate windows toward the center of

wall planes to emphasize the mass of corners.

• Express windows as “punched” openings

within solid, massive walls.

• Recess windows into the wall face to

emphasize building mass and to protect

windows from weather.

• Extend and slope window sills to shed water.

• Build a large porch to serve as an outdoor

extension of the building.

• Construct a vestibule or airlock for comfort

and energy efficiency.

·       Porch as an outdoor room

·       Recessed windows

·       Clusters of effective vertical windows

STRUCTURE

• In buildings designed for public use, express

the structure by exposing wood beams,

trusses, brackets, or framing.

• Handle cosmetic expressions of structure—

such as nonstructural log beams—with care.

MATERIALS

• Use stone, wood, heavy timber, and other

natural materials when they are available

and practical to use.

• Substitute manufactured materials, such

as synthetic stone, if they can achieve the

appearance of natural materials. The key is

to make the scale, color, and texture of

materials correspond to the setting.

• Consider costs and availability in remote

locations.

 

Roof Materials

• Design to achieve the look of cedar shake

shingles using such substitutes

as heavy-textured asphalt shake

shingles.

• Use metal if sensitively designed.

ROCKY

COLOR

• Analyze the local landscape for indigenous

colors and materials.

• Use color schemes that are inspired by rock

outcrops, leaves or needles, tree trunks and

bark, and colors found on the forest floor.

• Dominate the palette with earth tones.

• Integrate colors with natural materials

where possible.

• Use accent colors drawn from accents of the

setting: the green or orange-rust of lichen,

the red-brown of red-twig dogwood, the deep

burgundy of willow stands, and the ivory of

aspen bark.

 

Figure of the base of a tree suggesting use of natural colors:

• Warm grays of bark

• Light browns

• Rusty brown of needles

• Earthy rose of rocks

• Pale greens of lichens

• Deep forest greens of trees

• Golden brown of pinecones

• Yellows & violets of wildflowers used as accents
