108-7. Revised Two Story Design Principles.pdf7ft/ O SrC IRY IDIFSIIGI If"IRIII CIIIf"I1JES Introduction Cupertino's neighborhoods have developed over a period of decades with varying architectural styles. Homeowners and build- ers are allowed design flexibility if their design conforms to the following design principles. Two story homes with a second story to first floor ratio greater than 45% are allowed when they offset the building massing with designs that encompass higher quality architectural features and materials. Design Principles These design principles help integrate new homes and additions to existing homes with existing neighborhoods by providing a framework for the review and approval process. Where possible, additional details and examples have been provided. Conditions not covered by these examples will be evaluated on a case -by -cases basis. 1. Provide an identifiable architectural style. Attractive homes are designed by using elements from one con- sistent theme. It is best to work with your designer to identify and carry out one style around the entire house. 2. Design features, proportions and details to be consistent with architectural style. 3. Provide facade articulation. The following techniques offer ways to mitigate the bulk of larger homes in smaller scale neighborhoods and the impact of two-story tall walls on adjacent neighbors and the streetscape. • Second floor setbacks • Horizontal and vertical wall plane changes • Pop outs • Bay windows • Chimneys • Wide overhangs with projecting brackets • Juliet balconies • Belly bands • Window boxes and pot shelves • Landscaped trellises and lattices • Projecting window trim • Materials and color changes • Inset balconies • Applied decorative features • Recessed garage doors • Recessed windows • Window trim • Tall trees to break up views of long walls 4. Use high quality materials. 5. Ensure massing and scale appropriate to the architectural style. 6. Design with architectural integrity of forms, materials and details on all sides of the structure. 7. Provide symmetry, proportions and balance consistent with the architectural style.
