.'.:C°l 1 addition or new wing should not dwarf the footprint of an existing building. Adding 2 a new family room to an existing 2500 square foot two-story historic house may 3 not seem like a substantial addition. However, if the new room is completely 4 encircled by a deep porch the building footprint may have grown considerably. i 5 Depending on its location and detailing the addition may appear to be more � 6 noticeable and more important than the original building. Alterations or new � additions should always appear secondary to the original core structure. 8 9 The relationship between the various supporting buildings or outbuildings on the 10 site is also important. Often the character of the designated property is enhanced 11 by the presence of surrounding small outbuildings, such as a smokehouse, dairy 12 and well house. The construction of a large outbuilding in the immediate area (for 13 example, a new two-story, multi-bay garage) would negatively affect the existing 14 cluster. 15 16 Topography and natural features can be utilized to help hide new construction. A 17 new addition or detached building can be constructed with a lower elevation than 1s the existing historic building so that the new construction appears "sunk down" 19 and is less dominating on the site. New buildings can also be partially hidden 2o behind small hills or established tree lines. (See related Standards for Introducing 21 New Buildings to a Landmark Property.) 22 23 24 DESIGN STANDARDS for Size and Scale 25 26 III-C-1. Maintain the size and scale of all contributing buildings, especially the main 2� house. While constructing an addition will increase the size of a building, the 28 addition should not dwarf the older portions of the building or be so dominant that 29 the building takes on an entirely different character. 30 31 III-C-2. The proposal for any new addition should incorporate one or more of the three 32 common design tools: a connecting breezeway, an elevation setback, or a change 33 of materials. 34 35 III-C-3. Maintain the relationship between the contributing buildings. Contributing 36 buildings described in the designation materials should not become 3� overshadowed by new buildings, existing non-contributing buildings, or enlarged 38 contributing buildings, which were originally small. 39 40 41 Proportion and Rhythm 42 The repetition of building elements forms a pattern often referred to as "rhythm." 43 The placement of architectural components such as windows and doors can 44 create a sense of rhythm within a single building. For instance: a symmetrical 45 fa�ade containing identical windows equally spaced looks very different from an 46 asymmetrical fa�ade containing windows of different sizes in a haphazard 4� arrangement. Log buildings often have very small, almost square windows, 4s particularly in the upper levels; Federal, Greek Revival and Italianate houses often 49 have heavy window molding and window sills. Late-nineteenth century to early- 5o twentieth century I-houses tend to have large windows. All of these features s 1 provide important information about the history of the building and contribute to its 52 overall proportion and rhythm. 53 9/27/2010 Draft Orange County Design Standards 32
