Events on these days

Hollin Hills is a development in Fairfax County, Virginia, about 10 miles outside of Washington, DC. It has about 450 houses. It was designed by Charles Goodman and developed by Robert Davenport.

CAHH Design Review Guidelines
Section V – Design Guidelines

Design Guidelines The following standards are meant to give direction to homeowners and the Design Review Committee in evaluating whether proposed designs are in harmony and conformity with other structures in Hollin Hills.

A. SITING

Placement

The placement on the site of any occupied or accessory structure(s) should achieve a natural extension of the original conditions of the site and existing house.

Grading and Drainage

Avoid any extensive grading, cut or fill. Use existing elevations of the ground as the floor elevations of any structures to the extent possible. Structures should blend with the slope of the topography. Structures should step with the slope to fit the natural terrain. Contain runoff water drainage to the site or adjacent streets. Use of site retaining walls should be minimized.

Orientation

Orientation of the structures should be made to achieve privacy, views, good sun exposure for the site under consideration as well as protecting all the same features for the neighbors' site

Sensitivity to Neighbors: Sensitivity of the above issues for the neighboring sites' needs are critical particularly in relation to meeting the needs of any public right-of-ways (e.g. sidewalks, paths) to achieve a harmonious blend of the woodland spaces that characterize the entire community as well as each house site. For example, property boundaries which are clear legal demarcation lines and have precise set backs to establish construction position, do not in Hollin Hills establish design and spatial intent and are not noticeable

in the Hollin Hills siting patterns. This results in free-flowing spaces of a semi-cleared woodland character that should be conserved. Additions, fences, accessory structures, decks, etc. should avoid reinforcing property lines or any other geometric pattern not associated with the house.

Patios

Patios should be distinguishable from sidewalks, parking pads, or driveways. Care should be given to maintaining the unpaved quality of the Hollin Hills landscape. Any one patio should not be bigger than 50 percent of the square footage of the first floor of the house even if the patio has several split levels.

Driveways and Parking Pads

Such car areas should be kept to a minimum size.

Garden Structures

Such structures as arbors attached or detached from the house are encouraged if their specific design and size of-members, etc. conform to the house design and appear as a natural extension of the house.

Other

Other subjects such as mail boxes, certain minor exterior lighting, overhead vs. underground utility lines, flagpoles, tennis courts or pools do not require guidance; however, in the future the community may feel a need to address these items. See recommendation for Landscape and Maintenance Program Committee in Section VII.

Decks: Decks are an excellent design solution to integrate the house with the ground immediately adjacent. Care should be taken in the following areas of deck design:

.Avoid second floor decks on the front of the house which are visible from the street.
.Any one deck (counting any split levels) should not exceed in size more than 50 percent of the floor area of the first floor of the house.
Planting should be provided at post foundations and on low decks to screen structural elements and to soften visual impact.
The materials in terms of color and size of members should appear as a natural extension of the house.
Deck railings should be of a minimal size and, if possible, be integrated with a continuous bench. If the deck is low to the ground, which is preferred, railings can be eliminated totally. County codes must be met.
Other deck features such as hot tubs should not be visible to neighbors or from streets.

Fences and Walls

Fences are discouraged. If absolutely necessary, the more transparent or open the fence the better. Fences are especially discouraged in the front yard or side yards next to streets. Chain link, stockade, western, split rail, snow, chicken, or wind gate fences are not compatible with Hollin Hills design. The open grid metal farm fence variety is better, but all fending is discouraged. When fences are permitted, the following guidelines apply: fence posts should be on the inside face of the fence; planting should be used in conjunction with the transparent fence to minimize the appearance; retaining walls should be kept to a minimum; and screen or garden walls - typical of the original Hollin Hills design are acceptable if kept in short distances and low in height. If fences are required for dog runs, they should be sited as not to be border fences or visible from the street.

B. BUILDING SCALE, FORM, AND ROOFLINE

Proposed additions should not overwhelm the scale of the original house.

Proposed building designs should be composed of simple geometric shapes, following the small scale, light and transparent character, and strong rooflines used in the original houses.

Proposed plans should accommodate site constraints, that is, not every kind of addition can go on every lot.

The design of alterations and additions should be in harmony and conformity primarily with the particular plan type (Customline, Decca, etc.) of the house being modified.

C. MATERIALS, CONSTRUCTION DETAILS, AND COLOR

Wood siding should be either vertical tongue and groove, vertical T-1-11 plywood or horizontal clapboard. Wood siding should be painted or stained.

Brick walls should maintain the visual appearance of existing brick used in the house.

The material and color of roofs should be in harmony with the rest of the house.

Exterior colors should be earth tones or white. Loud or highly contrasting colors are discouraged.

Construction details such as door and window frames, joints between adjacent surfaces and other trim should be simple and without ornament

D. EXTERIOR WALLS

Walls should be unornamented, planar surfaces with tall, rectangular openings.

The use of modular wall panels is encouraged in additions and alterations to houses that were originally constructed with modular wall panels.

E. WINDOWS AND DOORS

Window and door frames should be rabbeted 2x6's with the glass, sash or, door set in. Other door and window frame treatments are permissible as long as they maintain harmony and conformity with the existing windows and doors.

The predominant window type in Hollin Hills is three feet wide and extends from floor to ceiling. It features a single fixed upper light and an operable lower sash approximately 25" high. For reference, this will be called a "Hollin Hills window."

The size and proportion of original Hollin Hills windows should not be changed without design review approval. This is not to suggest that in new construction the size and proportion of the original Hollin Hills windows must be used.

The exterior doors should be either flush (a flat surface not broken into smaller panels or windows) or fully glazed.

F. ROOFS

Roofs should be either flat or low-slope gable, low-slope butterfly or low-slope shed.

Large roof overhangs with thin edge profiles are encouraged except on the flat roof plan.

Roofing materials that retain the visual appearance of the original built-up roofs are encouraged.

Gutters should be plain box gutters with a rectangular profile.

G. GARAGES, CARPORTS, AND NONATTACHED STRUCTURES

Garages are not encouraged. Carports and garages are permissible when they can be integrated with the house and site. All non-attached structures should be in harmony with house and site.
