Staff Comments
Bungalow (c. 1890)Two-story frame with aluminum siding. Hip-roof attic dormer asphalt shingle roof covering. One-over-one double-hung windows (original or early on second level and replacements on first level.) One-story full front porch with hipped roof and central gable. Battered columns on brick piers are alterations from the original --likely sometime between 1920 and 1940. The two interior offset chimneys were removed prior to this owner. Brick foundation. Late, full-façade hipped-roofed addition on rear.
WINDOWS
2. If replacement windows are necessary, they shall be the same overall size as the originals, with the same pane division and the same muntin depth, width and profile. They shall be the same materials as the original windows, which were generally wood.
5. It can be appropriate to design and install additional windows on the rear or another secondary elevation. The design must be compatible with the overall design of the building.
7. Storm windows can be allowed as a way to increase the energy savings of a historic house. Interior storms should be considered. Exterior storms can be appropriate, if they are designed so their meeting rail duplicates that of the original window, and if they are wood or color clad metal, matching the building's trim. Exterior storm windows shall not be used unless they do not damage or obscure the original window and frames.
8. Reuse existing, serviceable window hardware.
MASONRY (see attache Design Guidelines)
Mortar Mix
In order to understand how to maintain and repair historic masonry, it is important to understand the characteristics of the mortar that unifies the masonry units. There is a very low percentage of Portland cement in old mortar, which is made up of much higher percentages of sand and stone than new mortar. This allows the mortar to expand and contract at the same rate as soft brick, stone, or older ashlar-faced concrete. If repointing is necessary, any new mortar should match the old both in color and in composition. Old deteriorating mortar that must be removed from mortar joints should be removed using hand tools.
ENTRANCES
6. Service (rear) entrances may not be altered to make them appear to be formal entrances by adding paneled doors, fanlights, transoms or sidelights.
7. Secondary entrances must be compatible with the original in size, scale and materials, but clearly secondary.
8. Determine if a storm door will be instrumental to saving energy. If a storm door is used, it must have a color-clad frame and a full-view glass, or be designed to respect the original entry door.
SECRETARY OF INTERIORS STANDARDS FOR REHABILITATING HISTORIC BUILDINGS
6. Deteriorated historic features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old design, color, texture, and other visual qualities and, where possible, materials. Replacement or missing features shall be substantiated by documentary, physical or pictorial evidence.
NATIONAL PARK SERVICE PRESERVATION BRIEF NO. 11
Excerpt on cleaning brick:
. . . individual pieces of stone or bricks that have been damaged by inappropriate alterations may be cut out and replaced with new pieces that duplicate the original. However, since an exact match will be nearly impossible to achieve, it may be necessary to paint the repaired masonry in order to create a harmonious facade. Replacement of a large area with new materials may not be acceptable as it may give the building a new, non-historic appearance inappropriate to the building style and period.
