Request Letter This Page Intentionally Left Blank Historical Preservation Committee, November 2024 126 University Ave Context: The owners moved to Los Gatos three years ago and were attracted to the charming historic district, active community, excellent schools, and proximity to nature. They purchased this home with the intention of preserving the integrity of its rich history while improving the livability for their family. The modifications are almost entirely interior facing, with the front elevation remaining unchanged and the FAR unchanged and compliant with town guidelines. As the construction has progressed on the project over the past ~6 months, the owners have three requested changes to the approved plans: 1.Remove proposed lite dividers on new windows and doors on the rear elevation and replace damaged windows 2.Modify lite dividers on the new glass roof on the rear elevation 3.Modify the design of the new back door on the rear elevation ATTACHMENT 1 Historical Preservation Committee, November 2024 1. Request to remove the proposed lite dividers (i.e., muntins) to new windows and doors on the rear elevation of the house • In December of 2022, the Historic Preservation Committee approved the construction of exterior alterations on the home, contingent on the committee’s request that metal dividers (i.e., muntins) be added to the new doors and windows on the rear elevation of the house (see Exhibit 1a). • As construction has progressed, we have continued to assess the aesthetics of the renovation to preserve the historical integrity of the home. We note that the requested muntins on the rear windows and doors are not consistent with any of the original existing windows on the home (see Exhibit 1b), which will remain untouched with the renovation. • Given that none of the original existing windows or doors have muntins but rather have tall vertical windows that are more consistent with the Queen Anne Victorian style of the home (see Exhibit 1c), we are requesting that the Historical Preservation Committee approve the removal of the proposed muntins from the new rear windows and French doors. • After inspecting all existing windows, we have identified construction damage caused by old wood and the overall lifting/securing of the house during excavation. Our proposed new windows were approved by the planning committee and the Historic Preservation Committee in their December 2022 meeting as aluminum wood clad. For consistency, efficiency, and aesthetics, we will use the same material and retain the same window frames as the existing ones, only upgrading the window technology. Exhibit 1a: Approved plans as of December 2022 (rear elevation) Historical Preservation Committee, November 2024 Exhibit 1b: Existing windows and doors Front view porch - Existing front porch window to remain as is (no muntins) - Replace with new window technology with the same style and retain the window framing as is. Historical Preservation Committee, November 2024 Front view living room - Existing front bay windows (living room) to remain as is (no muntins) - Replace with new window technology with the same style and retain the window framing as is. Historical Preservation Committee, November 2024 Side view driveway bedroom - Existing south-side window (bedroom) to remain as is (no muntins) - Replace with new window technology with the same style and retain the window framing as is. Historical Preservation Committee, November 2024 Side view driveway bathroom - Existing south-side window (bathroom) to remain as is (no muntins) - Replace with new window technology with the same style and retain the window framing as is. Historical Preservation Committee, November 2024 Rear view bedroom - Existing rear window (bedroom) to remain as is (no muntins) - Replace with new window technology with the same style and retain the window framing as is. Historical Preservation Committee, November 2024 Side view adjourning house - The existing north-side window (dining room) to remain as is (no muntins) - Replace with new window technology with the same style and retain the window framing as is. Historical Preservation Committee, November 2024 Existing French doors off primary bedroom to be replaced due to renovation (no muntins) Existing French doors off main home to be replaced during renovation (no muntins) Historical Preservation Committee, November 2024 Exhibit 1C: Queen Anne style home (A Field Guide to American Houses) – tall double- hung windows with no muntins Historical Preservation Committee, November 2024 2. Request to modify the lite dividers on the glass roof addition on the rear elevation of the house • In December of 2022, the Historic Preservation Committee approved the request for a glass roof to cover a small (4 x 5 feet) addition to the primary bedroom. The approved design of this glass roof depicted metal tubing dividing the roof into 8 smaller sections (see Exhibit 1). • As construction has progressed, we have continued to assess the aesthetics of the renovation with regard to preserving the historical integrity of the home. Similar to the requested muntins on the rear window and doors outlined above, these glass roof dividers would not be consistent with any of the original existing windows on the home (see Exhibit 2a-f), which will remain unchanged with the renovation. • In addition, this glass roof is intended to open and close to allow for natural airflow and improved energy efficiency of the home, and the only manufacturer able to build this custom construct (Velux) requires a three-panel design (see Exhibit 2) to function as intended. These three panels would be vertical rectangles (87 by 30 inches), which mimic the shape of the existing original vertical windows (76 by 30 inches) that will remain throughout the home, including the window right above the glass roof (see Exhibit 1). • Given our desire to maintain an appearance that is consistent with the original historic existing windows and considering the manufacturer’s requirements to fabricate this roof, we are requesting that the Historical Preservation Committee approve the glass roof with three vertical panels. Historical Preservation Committee, November 2024 Exhibit 2: Proposed design for rear addition glass roof Historical Preservation Committee, November 2024 3. Request to modify the design of the new back door on the rear elevation of the house • In December 2022, the Historic Preservation Committee approved the construction of exterior alterations on the home, including a wider French door for the main rear entrance of the home (see Exhibit 1) at the committee’s request as an alternative to the originally proposed bifold doors, which were deemed to by the committee too modern. • The size of the approved double French door is 108 inches wide x 84 inches tall, which is significantly wider than standard French doors (typically ranging in width from 30-72 inches). French doors with this width pose challenges both in utility (for example, the wide outswing requires more space and extra reinforcements in the framing) and safety (for example, the extra weight of the doors shutting). • In addition, the position of the wider French doors is not centered with the main interior stairs that transition from the upstairs level to the downstairs level and exterior of the home. This off-center position would disrupt the natural flow of movement and diminish the utility of the space. • To improve the usability and safety of the doors while maintaining historical integrity and the additional light a wider entrance would offer, we are requesting that the Historical Preservation Committee approve a modified design of standard-size French doors (76 inches wide x 82 1/2 inches tall) with a single sidelight (18 inches wide x 82 ½ inches tall) configuration that would align with the window above it (see Exhibit 3).
