The following Architectural Design Guidelines apply to all residential development projects and/or community recreational facilities within Castle Pines North.
1. Roof Design
• Roofs are very important to the overall integration and compatibility of different developments within Castle Pines North. Their design must be given careful consideration as they will be highly visible from streets, other buildings and most neighboring sites. Allowable roof designs are: gable roofs, hip roofs, gambrel (mansard) roofs, shed roofs and flat roofs.
• The choice of roof form should be greatly influenced by the angle and height from which the building will be viewed. Flat roofed buildings would only be considered appropriate on upper hillsides where viewed from below. The view of flat roofs from above is often very unattractive unless handled with particular care.
• The use of major rooftop elements such as dormers, chimneys or skylights should enhance the roof form and be an integral part of it. Special attention should be given to the design and placement of mechanical systems (i.e. vents, etc.) on roofs of residences which will be viewed from above. Exposed metal flashing vents and flues should be painted to match the color of roofing materials.
• The minimum roof pitch allowed on a major roof form is 4:12. The pitch of lesser elements such as porches, dormers, etc. may be lower if consistent with the architectural design. Domes and A-frame buildings are considered inappropriate.
2. Building Design and Groupings
When multiple structures are planned as part of a single design project, they shall be designed in a unified architectural and spatial manner resulting in integration of structures into related groupings. Single-family detached residences within a single design project, however, should not appear as row housing. In order to avoid this, variations should be provided, wherever possible, in building elevations as well as building setbacks from the street and sideyards.
3. Material Recommendations
Certain building materials are more desirable for use in Castle Pines North and they have been identified below. Where feasible, the natural color and texture of the materials should be expressed.
• Roofs - Within a residential development, all roofs shall be built using the same roofing materials in order to achieve an overall design continuity, Suggested roofing materials for the Castle Pines North Community include cedar and other wood shake shingles, fired tile, and slate shingles. The use of metal roofs is acceptable; however, in no instance will metal roofs which reflect direct sunlight onto an adjacent property be permitted. If metal roofs are used, they shall be surfaced with a low-gloss finish or capable of weathering to a dull finish. Metal roofs shall generally have a standing seam in order to provide some relief to the roof surface and be of a heavy guage. Asphalt, polyurethane and corregated aluminium are unacceptable roofing materials in Castle Pines North. (SEE APPENDIX "E")
• Exterior Walls - All exterior wall materials utilized should be compatible with adjacent residences/buildings. Siding materials must be continued down to within 6" of finished grade on any elevation, thereby eliminating large areas of unfinished foundation walls.
Suggested exterior wall materials are redwood siding, cedar siding, other types of wood siding, stucco, brick and stone. Horizontal, vertical and diagonal patterns are acceptable siding patterns. Incorporating more than one material on exterior walls may be desired, but special care should be taken so that materials do not detract from the building's overall design and form. Masonry veneers shall be consistent on all elevations.
• Colors - Exterior wall colors should be compatible with the site and with surrounding buildings. Natural colors (i.e. earth tones) should be utilized. Primary colors or other bright colors should be used only as accents and then only sparingly.
