Board approves windows and door replacements at Michael Singer estate with limits on reflective glass

The Historic Preservation Board on Sept. 17 approved a certificate of appropriateness for replacement windows and doors at 321 Northwest First Avenue, property of the estate of artist Michael Singer, while imposing conditions on reflective/low-e glazing. The board approved anodized aluminum frames and allowed certain low-e treatments only on limited openings after public comment and staff analysis.

Why it matters: The property sits within the Old School Square Historic District and contains artwork the estate says it must protect from sunlight. The applicant sought anodized aluminum frames with low-e glass for some west-facing openings to protect artwork and improve hurricane resistance; staff and the board weighed energy-code needs, historic visual consistency, and long-term conservation goals.

Jason Bregman, a personal representative of the estate, described Michael Singer's national reputation and said the estate plans to retain the property for foundation use. Bregman told the board the replacements are needed for hurricane protection, energy efficiency and to protect valuable artwork: "...the old openings with shutters are being replaced for security, hurricane protection, energy efficiency, and aesthetics." He also said the estate used anodized aluminum frames to match existing appearance and had ordered windows with low-e coating for some west-facing openings.

Staff noted the structure is classified as a noncontributing ranch-style residence from 1975 but pointed out the board's previous direction: contributing structures must use clear (no tint or reflective low-e) glazing, while noncontributing structures may use gray-colored ("graya") glass to meet Florida Building Code energy calculations. Staff warned that low-e glass varies by manufacturer and can create inconsistent color/reflectivity over time.

Public commenters strongly supported retaining the property and protecting the artwork; neighbors said the site contributes to a mature tree canopy. The board debated whether to require the applicant to substitute gray-tinted (graya) glass or approve the low-e glazing as proposed. The applicant said some windows were already ordered and in a warehouse and expressed concern about the extra cost of field reglazing versus factory replacement (the applicant estimated reglazing might be in the mid-thousands of dollars, "probably somewhere around $8,000").

Decision and conditions: The board approved the COA for 321 NW First Avenue with conditions: (1) the garage-facing window identified in the staff materials (window 13) must use a gray tint (graya) rather than low-e reflective glass, (2) the proposed front entry will be frosted glass as shown in the application and was included in the approval, and (3) other window changes that meet administrative standards may proceed. Staff explained that most replacement windows around the property would be handled administratively and that only the limited west-facing glazing required board direction.

Staff also recorded on the record that the property remains legally single-family residential use; if the foundation or owners change the use to a commercial operation in the future (studio/office-only without residency), a separate change-of-use or permitting would be required.

The board's action balanced the estate's stated need to protect artwork with the historic-district goal of visual compatibility and the city's energy-code requirements for noncontributing structures. The applicant may proceed to permitting under the conditions set by the board.
