Historic houses in rural <br /> 9 areas are often viewed from a public road some distance from the actual building. <br /> lo The overall visual impression of the main building or building complex may be <br /> 11 linked more to its size and scale than to its specific details or individual features. <br /> 12 Houses can be readily identified by their height (one story, two stories, etc.), their <br /> 13 scale, (large, small, sprawling, compact, etc.) roof type, (hip, gable, etc.) and <br /> 14 other principal features such as a front porch or a large chimney. <br /> 15 ,. . <br /> 16 ;a,�; � � � i.�{ �:. <br /> 1g �^�� j��; 4�� j' .' y `, <br /> 1 7 �f���� ��� � �"m� �y��� �'i 4 , <br /> V � y�'t��(�'4�� <br /> 20 _ "` �� ,��a` "` �• <br /> �` ,.. <br /> � r k F <br /> 21 �� e�,, � °r� •�*` <br /> "i;��� �.✓„ <br /> �� <br /> � <br /> � ' ��, � � v <br /> 22 � �, ,�� � � <br /> , <br /> � r „ <br /> , <br /> ti. <br /> � � t - � , � <br /> 23 `� ' �•- �' + <br /> , W <br /> � ,. a , <br /> a-- �i c¢` � - :.:• <br /> 24 ,r�.* � ° <br /> �. � <br /> . : <br /> „ . <br /> , <br /> . <br /> 25 ' <br /> , � �� v�x�. `",� <br /> 26 �:,,�.'`��'�. �° �.� 3� .�.... ������ . <br /> 27 � <br /> ' ° ,� <br /> 28 ° '_ „.:�� : <br /> y._ _ �� .

For example, if the main house of a designated property consists of a <br /> 34 large two-story front block and a small one-story rear ell, an application to enlarge <br /> 35 the ell to three stories would probably be denied. The proposal would make the , <br /> 36 secondary section of the building appear larger and more important than the i <br /> 3� fa�ade or front elevation. <br /> 38 <br /> 39 Unless the project is part of a museum-quality reproduction, preservationists <br /> 4o usually try to design additions that are visually compatible to earlier sections of <br /> 41 the building but clearly of a different time. Three design tools are commonly used <br /> 42 to achieve this. <br /> 43 1) The addition is connected to the original building using a "hyphen" or <br /> 44 breezeway to visually (and physically) separate the two units. <br /> 45 2) The addition is setback from the front wall plane of the original building. This <br /> 46 approach usually makes the addition appear secondary to the original <br /> 47 building. <br /> 4s 3) The addition is finished using different materials from the original building. For <br /> 49 example, if the main building is constructed of stone the addition may be <br /> 5o covered in wood siding. The details or trim work should be simpler than the <br /> 51 trim on the original building. <br /> 52 <br /> 53 The building footprint is another component of scale—essentially what the <br /> 54 building looks like from the air looking down (an aerial view).
