Introduction And Overview Of Architectural Styles
The homes at SweetGrass will have a consistency of character and quality, while allowing individual variety and styling preferences. This SweetGrass Style and Architectural Vision Booklet serves as a design framework to guide architectural decisions by owners who must obtain approval of their plans from the Reviewer prior to commencing construction.
SweetGrass homes will have the following things in common:
• All home styles found at SweetGrass are traditional. Builder homes lacking identifiable stylistic roots are prohibited.
• All homes styles will be reviewed by the Reviewer
for their compliance to this SweetGrass Style and Architectural Vision Booklet and the SweetGrass Design Guide.

SweetGrass homes are distinguished by the following features:
Pre-approved colors shall be chosen from the SweetGrass Color Collection (page 15). Other colors may be approved, if consistent with the color concepts of SweetGrass.
Cladding materials will continue horizontally in a consistent manner around all sides of the homes.
Homes shall have a raised masonry foundation appearance (21” minimum unless approved by Reviewer). Front-facing foundations shall be veneered with native stone (preferred), cultured stone or architecturally designed and landscaped to minimize an alternative veneer. All veneers and design alternatives are subject to approval by Reviewer. Side-facing foundations shall have a minimum of 60% stone (preferred), cultured stone or stucco. To soften the appearance of stucco, if used, then a minimum of 60% of the stucco surface must be obscured by landscape shrubs or trees (given an adequate size and growing period). Stone treatment on side and rear foundations walls shall complement and align with architectural elements on the wall area above, such as secondary volumes, piers, or columns. Refer to Prohibited Architectural Features and Details for additional foundation considerations, page 25.
Generally, windows shall be vertically proportioned in traditional single-hung, double-hung, or casement styles. Windows on side
and rear elevations shall be consistent with those on the front elevation. Grills shall be permanently attached to the outside of the glass. With single- and double-hung windows, use of non-divided lower sash is permitted; however, upper sash and/or transform lites shall have divided lites. Exterior components of all windows (frames, sashes, grills) shall be painted. Metal clad wood windows are permitted if such window manufacturers offer appropriate colors.
All windows and doors on all sides of the homes shall be trimmed with a 3 1/2” minimum-width trim.
75% of homes will be roofed with cedar shakes or pressure-treated pine shakes. For certain styles, an accent roof of standing seam metal or metallic shingles in metallic color finishes are permitted. Examples of permitted colors are aged copper, weathered gray, copper, and sliver galvalume. Note: 50-year, five-tab architectural or dimensional shingles may be used, subject to Reviewer and approval.
The principal chimney of the home shall be veneered in native stone (preferred) or veneers with mortar joints fl or “full” style. Thin cut stone may also be used on chimneys.
If gutters are used, they shall be half-round style in copper or metallic colors, or painted in dark brown. Downspouts shall be round type in above mentioned colors.
For lots on which they are feasible, garages shall be fully detached or semi-detached in appearance. Single carriage-house-style doors are required. Garage doors can never directly face roadways.
Preservation of large caliper trees is critical. Landscape plantings should emphasize native plants, with non-native species used to add color and texture. The use of non-native invasive species is prohibited. See Landscaping (page 20).

SweetGrass Architectural . Styles
Old Blowing Rock Style:
This style is best characterized by its simple volumes and unique large-scale bark shingles (10” exposure) as the principal siding material on all sides of the home. The color of the siding is generally natural, however the windows and doors, and their associated trim, are often painted in an accent manner. Native stone foundations and chimneys are the final components of this style.
American Shingle Style:
This American classic style affords the homeowner at SweetGrass a somewhat more ornamented style than that of the Old Blowing Rock Style. The shingle siding is smaller and less rustic; trim profiles may be more sophisticated; window configurations may be more organic. However, through design restrictions on ornamentation and color, and requirements for stone foundations and chimneys, the style is made “mountain-appropriate” at SweetGrass. The American Shingle Style gives architects and designers considerable creative leeway at SweetGrass.
Mountain Rustic Style:
To evoke an authentic eastern mountain look and to visually “upgrade” the architecture, the log cabin architecture at SweetGrass is distinctive in three important ways: (1) log profiles are square cut in section (not round); (2) roofing should be cedar or pine shakes, or standing seam metal in metallic finishes (see Signature Roof Materials, page (2); and (3) all roof designs and window configurations that reference a western “ski chalet” look are prohibited. Overall the Mountain Rustic Style has an understated quality that blends softly into the hillsides and meadows.
Adirondack Influences:
Use of accent details from this rich architectural movement born from the camps and lodges of New York State is encouraged at SweetGrass. Such accents include round log columns and round roof brackets, natural twig and laurel branch railings, and battered and/or organic stonework. Carefully handled by the designer, these details can bring welcome texture and uniqueness to the three styles of homes at SweetGrass.

Old Blowing Rock Style - Key Elements
Massing Characteristics: Smaller homes of the Old Blowing Rock Style have simple one-and-one-half story massing, best described as a cottage scale. See S-1.
Larger homes of this style have L-shaped and I-shaped footprints in two-story heights with other secondary appendages as single-story volumes. Widths of the major volumes are usually one-room widths. See S-2 and S-3.
Key Details: S-1
• S-4 illustrates the single most important detail of the Old Blowing Rock Style: native bark shingle siding with large (10” vertical) exposure. This shingle is left in its natural fi (no staining or painting).
• 20” minimum depth overhang at all rakes and eaves of primary volumes of the home.
• 12/12 roof pitch at all primary volumes typical (10/12 is minimum allowed).
• Porch is dominant feature, usually spanning between wings of the home or as a two-sided wrap-around porch. See S-2.
• Traditional windows with upper sashes having multiple lites.
S-2
This style epitomizes the visual themes of the high mountains of North Carolina – stone, bark, weathered wood. As such, this style has established itself as the authentic mountain architecture of the Blowing Rock area.
At SweetGrass, Old Blowing Rock Style is held in high esteem: it is the primary style of the community. Its understated rustic simplicity, and its ability to blend with the mountain setting while simultaneously presenting attractive, crafted homes, makes it unique.

American Shingle Style - Key Elements
Shingle Style was born between 1880 and 1900 in the fashionable summer destinations of Long Island and Cape Cod. Here, architects created stately yet casual homes that seemed to link naturally to the land. The organic shape of these homes complemented the rolling, rocky landscape on which they were sited. Their cascading roofscapes and rambling masses blended with the local natural land forms.
At SweetGrass, the rustic qualities of the style are emphasized. Columns shall generally be timbers in square or rectangular cross sections (round section classical columns are only allowed by review).
Massing Characteristics:
Sketches S-1 and S-2 illustrate front gable Shingle Style-inspired homes. These homes add multiple large secondary volumes to main volumes to create complex, organic roofscapes. Common Shingle Style characteris- tics include multiple mulled divided lite windows and round or oval ac- cent windows.
Sketch S-3 illustrates a fully shingled home executed in a classical, formal manner. This approach is inappropriate for SweetGrass.
Active roofscape with dominant form (asymmetrical front gable) and secondary forms; use of multiple mulled windows with upper sashes with multiple lites; shingles as primary “skin”; shingles turn corners; use of stone as horizontal base linking home to site.
S-1
Key Details:
• Asymmetrical roof massing with steeply pitched roof lines, often with long slopes. Hipped roof dormers are a hallmark feature.
• Narrow roof overhangs at rakes; deeper overhangs at eaves; eaves have flat soffits.
• Porch is dominant feature, sometimes recessed beneath main roof, with supports being shingled piers, stone piers and classical columns.
• Exterior material is predominantly shingles. Shingles act as “skin” and turn corners. A minimum of 55% of the home’s walls shall be shingles.
Materials:
• Non-glassed wall areas must be a minimum of 55% shingles. Shingles generally are to be square cut; only limited use of decorative shingles is permitted.
• In addition to shingles, board and batten, board on board, buttboard horizontal, and rustic wide plank lap siding with feathered cornered treatment are permitted cladding materials.
• Native stone (foundations, foundation piers, chimneys, 3-sided ad- ditive volumes).
• Roofs should be cedar shakes or pressure-treated pine shingles.

Mountain Rustic Style - Key Elements
The Mountain Rustic Style homes at SweetGrass are inspired by early American cabins of the eastern United States. These log structures featured hewn logs rather than round logs and traditional multi-paneled windows.
At SweetGrass, homes built in this style will be larger than those early cabins and potentially have more complex massing. Yet the honest simplicity of those original woodland cabins is the principal hallmark of this style at SweetGrass.
Massing Characteristics: Smaller homes shall have generally simple massing (see S-1). Larger log homes are encouraged to have multiple cross-gable volumes (S-2) and additive wings or pavilions connected by glass breezeways (S-3).
Key Details: • Traditionally proportioned single or double-hung
windows and casement windows are permitted. Triangular shaped windows and trapezoidal windows are not permitted. All windows shall generally have multiple panes within each sash, although use of non-divided lower sash is permitted. Grilles must be permanently attached to the outside of the glass.
• Roof designs and window configurations that reference to “western style cabins” or “ski chalet looks” are prohibited.
• Peeled round log and Adirondack twig log columns and beams are permitted as appropriate components at porches, decks and railings.
• Cabins shall be stained in a color from the SweetGrass Collection (Page 15). The typical yellow-orange log color found
traditional windows and doors with divided lites
expressive native stone piers at deck corners
stone on principal chimney
cedar shake roof
shed dormers with round log accents
square log profile with dovetail corners and chink-groove detailing
on most manufactured logs is strictly prohibited. S-1

General Requirements – Color Collection
The SweetGrass Color Collection emphasizes woodland and mountain inspired colors. These colors … browns, grays, tans and greens … are generally understated. Yet the Collection provides ample selection of accent colors to give each home the correct “color liveliness.”
The Collection is structured in three color categories:
• Base color - the home’s primary color. This is the color the siding or logs will be painted or stained.
• Trim color - the color for the home’s window and door trim,
and when appropriate, the roof trim components.
• Accent Color - to be used in limited ways. Appropriate accent components are window sashes, featured doors and shutters.
The Collection encourages color schemes respectful of the traditional cottages of the Blowing Rock area. Most of these homes feature unstained bark shingles with white trim. Painted traditional cottages tend to be medium to dark colors, also with strongly contrasting trim. The Collection also provides colors for more monochromatic approaches. Here, trim colors have less contrast. All color schemes must be approved by the Community Architect. Additional color will be considered upon review.

General Requirements – Site Planning
At SweetGrass, there is a strong desire to retain the natural beauty of the site by making modest and restrained site improvements. It is important that buildings be placed in a way that minimizes their presence from the street and from surrounding properties. The building should be designed to fit the site conditions rather than making massive changes in the site to fit the design. This is especially important on ridge lots where houses should not be viewed from below. Houses should be designed so that they are well rooted and anchored onto their site.
1. Houses must be designed to fi their sloping site rather than the site made to fi an inappropriate house.
2. Each site plan is subject to the discretion of the DRC on an individual basis with concerns of the homeowner,
the community and the natural surroundings in mind.
3. It is important to remove as few trees as possible, stepping a house or bending a driveway around mature trees rather than removing them. Clear cutting of a site is strictly prohibited. Please refer to the SGCA Charter and the SweetGrass Design Guide for requirements for tree removal.
4. Site plans should be designed with the intention to disturb as little of the property as possible.
Excessive grading for any purpose is not acceptable.
17
General Requirements – Materials and Grading
Materials:
Materials used around the exterior of any home at SweetGrass should respect the natural surroundings of the mountain environment by blending in with the native landscape. Elements that are placed in the landscape should remain in harmony with what is native to the Blowing Rock area.
1. Materials for walkways and patios include: flagstone, concrete pavers or pea gravel in earth tones.
Materials not allowed for walkways and patios: asphalt, concrete, stamped concrete or any other material in bright or white colors.
2. Finish materials for driveways include: concrete pavers, exposed aggregate concrete, asphalt
pavement, crushed pea gravel and stained concrete. No white or bright colors are permitted.
3. All walls must be built of stone that matches the colors of the surrounding native stone. Wall stonework shall appear organic in nature, in varying sizes. Key-stone type walls and rail road tie walls are prohibited.
4. Entry from the street should be understated. No tall piers or lampposts will be permitted.
Grading:
Site grading at SweetGrass should reflect natural forms that take shape gradually, giving the landscape a naturalized appearance. Each home site and driveway location should be chosen to minimize the need for cut and fill and create as little disturbance as possible. This allows for the topography to be integrated into the design of the architecture and vice-versa.
1. Driveways should follow the natural topography and shall be kept narrow with a maximum width
of 12 feet. Large formal auto courts are prohibited.
2. Every attempt must be made to minimize cut and fill necessary for the construction of a home.
3. Retaining walls may be used when necessary to reduce the amount of cut or fill. However, retaining walls must not be excessive in height or length and may require a vegetative buffer to soften the effect.
18
General Requirements – Drainage, Stormwater and Erosion Control
Drainage and Stormwater:
Most of SweetGrass Lake drains directly into Boone Fork Creek, which is one of the most strictly protected waterways in North Carolina. Protection of the creek is crucial and a condition of development at SweetGrass. The delicate balance of stream ecology can easily be upset by sediment, water-borne pollutants or just a small amount of oil from machinery. Therefore, it is pertinent that every effort be taken to care for Boone Fork Creek by way of keeping drainage and stormwater in check.
1. Drainage should not be directed at any built structure or onto a neighbor’s property in an
unnatural way.
2. Flow of stormwater should not increase from pre-development conditions.
3. Homeowners are encouraged to direct stormwater runoff into bio-swales and rain gardens to help clean and slowly release stormwater.
4. The use of rain barrels is encouraged to hold excess run-off from roofs and
for watering landscapes.
Erosion Control:
Erosion control is an important aspect of the building process; it contains disturbance to each lot and helps to preserve the natural systems already in place.
1. Silt fence is required on the downhill side of the entire disturbed site and/or in any
other circumstance as required by Watauga County.
2. No off-site erosion or sediment is permitted.
19
General Requirements – Garages
1. Garages must be built as accessory structures that are fully detached or semi-detached. See sketches S-1 and S-2.
2. All garages must have single garage doors. In order to keep the scale appropriate for
architectural styles found at SweetGrass, double wide garage doors are not permitted. Garage doors shall complement the style of house in color and materials.
3. Story-and-a-half garages, which allow for storage or living space above, will be allowed
provided the overall building has a scale lower than the peak of the main home.
4. Finish materials and all other accessory structures must be of equal quality as the main house and have the same level of detail. Eaves should generally be low so as to de-emphasize the garage structure.
5. With semi-detached garages, the face of the garage must be located behind the
mid point of the main house, unless topography dictates otherwise.
6. Garages may be attached to the main house with covered walkway, provided the walkways are integral in the design of the building.
7. Due to limitations, garages may not be feasible for cottage/cabin lots.

Landscaping
Landscaping is an important aspect of anchoring a home on a mountain site and integrating it with its mountain surroundings. It is particularly important at a development such as SweetGrass where buildings should have limited visibility from any other vantage within or surrounding the community. All landscaping shall preserve the subtlety of the SweetGrass community.
1. Only plants listed on the approved plant list shall be planted on the property. See list of approved plants.
2. The use of alternating groupings of plants with different characteristics is encouraged to provide variety and create a sense of visual
rhythm. Tiered or layered planting schemes are also encouraged, as opposed to plant groupings that are all of the same level.
3. Parking areas should be screened from the road with a landscape buffer.
4. The buffer should consist of shrubs and other plants arranged in groups or rows to provide a maximum screening effect. Shrubs should be evergreen and at least 4 feet tall when planted, projecting an average of 6+ feet normal mature growth.
5. Excessive use of yard art or large pieces of yard art are prohibited. Yard art of any kind is prohibited if it is
visible from the street.
Landscaping Zones:
Each lot is comprised of two different landscape zones that determine the planting and maintenance of each. This allows for homes to not be seen from the road or from the valley below, but also to be maintained up close to provide intimate entertaining and family space.
1. The Garden Zone accommodates a higher use area directly around the home. It allows for manicured native
plantings as well as an area for patios, walkways, small lawns, and other designed landscape features.
2. The Conservation Zone should conserve the natural character of the site by protecting and enhancing the health of existing native plant communities. Work in this area should only consist of removing exotic and invasive plants and care and replacement of existing natives. It should have an undisturbed woodland character.

Prohibited Architectural Features and Details
One of the most successful ways to guide the visual quality of a community is to clearly state what is not permitted. A focus on what not to do provides a guarantee that key design fundamentals will exist while allowing creativity in the design of the homes.
The following architectural features and details are prohibited in order to maintain the integrity of the community:
1. Builder-style multi-gabled front facades and lodge-style back facades. Home shall be traditionally inspired from the three styles defined by this Style Book.
2. Change of cladding materials at any outside corner. All four walls of the principal (largest) volume must be the same material.
3. Stucco or parged front foundation walls. Front foundation walls shall be veneered with 100% native stone. Side walls shall be no less than 60% stone and must relate to volume change in massing of home.
4. Poorly proportioned or overly scaled windows. All windows shall be traditionally sized and properly proportioned to the building style.
5. Two-car garage doors or “budget-priced” garage doors. Garage structures shall be semi-detached or fully detached. Designers shall make every effort to configure the garage on the site to conceal the garage doors from the roadways at SweetGrass.
6. Vertically exaggerated entry ways.
7. “One-dimensional” stone gabled accent volumes. Three-sided stone add-on volumes may be approved upon review.
8. Windows with “grilles-between-glass.”

Harsh red brick. Stone-color brick on accent volumes of a house, may be presented to the Reviewer for consideration. Also, bricked wall areas may be washed with parge coat and fully painted in woodland-tone color.
Bird-box cornice returns. One-piece roof rake trim or gable trim.
Steeply pitched cornice "roofs" at pedimented gables.
Narrow door and window trim. PVC or synthetic railing system at front and sides of homes.
Incorrect shutter detailing. Camed glass style doors or windows.
Chimneys cladded with lap siding or exposed prefab flue. Property fences of any kind.
9. Vinyl or aluminum siding or soffits.
10. Synthetic stucco.
I
t probably won’t surprise you that I think the architectural elements of SweetGrass are almost as important as the natural ones. After all, my trade is architecture and I consider myself quite fortunate to have led the home design work for this wonderful little community.
Planning SweetGrass was a relatively simple process … once I understood how and where the community fit within its surroundings. I spent a number of days exploring the area, taking many photographs of existing homes and structures. I also researched the region’s architectural heritage, focusing on the materials and details that are unique to this beautiful place.
What I uncovered during this process inspired the design elements you’ll see in this guidebook. I’ve identified three distinct “styles” of architecture for homes at SweetGrass and have articulated a set of standards to ensure consistency, yet provide freedom and flexibility to owners and their builders. With these guidelines in place, owners can be assured that
every home to be built here will meet a certain threshold for quality –
which I know to be an important part of the buying decision.
In the end, the homes and architectural features I’ve designed were
indeed inspired by what I found here naturally – and, most especially,
by nature itself. There is nothing I want more than to help create a
community that fits perfectly within these majestic mountains, miles of
fertile land and clear, untouched lakes and streams. I do love my home in
Atlanta, but this is, without question, a paradise.
