ALTERATIONS: The house has aluminum siding and storm doors. The rear 14x16 addition was added in 1959 as a screened in porch. The garage was moved further away from the house in • January, 1959. The house was re -roofed in April, 2002 with COA#2002-0405. APPLICATION ITEMS: Replace existing single pane aluminum windows with Marvin thermo-pane aluminum clad wood double hung windows. DESCRIPTION OF PROPOSED PROJECT: The homeowners wish to completely remove the 20 original single pane aluminum window -storm window system in the body of the house and replace with Marvin thermo-pane aluminum clad wood double hung windows replicating the 2/2 muntin pattern. The wood aluminum clad windows have a wider frame and will reduce the light by 2 1/8 inches. In discussions with Mr. Derbin of Riverside Construction the original window system is composed of an inexpensive aluminum that has very little or no insulating value so the window frames become very cold the winter and very hot in the summer. STANDARDS AND GUIDELINES: East Wavne Street: C. WINDOWS AND DOORS Window and door frames are of wood or steel (some casements) or in the case of brick structures, stone sills and brick lintels. Where metal or vinyl siding has been applied, window trim has been covered. Storm windows are of wood or aluminum. Required Original windows and doors shall be retained including sashes, lintels, sills, shutters, decorative glass, pediments, hoods, and hardware. When deteriorated beyond repair, they shall be replaced with units and trim resembling the original. Recommended Wood frame storm windows and doors painted to match the original should be used but should • not damage existing frames. If new sashes or doors are installed, the existing or original materials, design, and hardware should be used. When metal storm doors are used, they should be painted, anodized or coated to match the existing. When awnings are used they should be of canvas material. Prohibited Original doors, windows and hardware shall not be discarded when they can be restored and re- used in place. New window and door openings which would alter the scale and proportion of the building shall not be introduced. Inappropriate new window and door features such as aluminum insulating glass combinations that require removal of the original windows and doors shall not be installed. Not Recommended Awnings, hoods, and fake shutters made of metal, vinyl, or fiberglass should not be used if they would detract from the existing character or appearance of the building. STAFF RECOMMENDATION: This project poses some issues as the Staff has never seen a window system quite like this one. The window frames are very narrow and therefore sash light is large. Clearly the proposed double hung windows will alter the look of the house by reducing the size of the sash light and increasing the size of the frame. Interior storms would not alleviate the temperature/moisture/leaking problems with the frames. "Sash Packs" are not an option since there would be no compatible frames to insert them into. The installation of Casement Windows which have a narrower frame would alter the look of the house as well; and may increase the number of windows in each opening to two. The Office called HOPE'S Steel Windows for an estimate for a 36" x 56" steel frame window in their residential Landmark Series and was given the estimate of $3,500.00 per frame per window excluding the cost of the double pane glass. That • would give the base cost of this window replacement project at $70,000.00 excluding the cost of 2
