HISTORIC PRESERVATION COMMITTEE
REPORT
MEETING DATE: 2/26/2024
ITEM NO: 2
DATE: February 21, 2025
TO: Historic Preservation Committee
FROM: Joel Paulson, Community Development Director
SUBJECT: Consider a Request to Construct Exterior Alterations (Window and Door
Replacement) to a Pre-1941 Single-Family Residence on Property Zoned R-
1:20. Located at 17121 Wild Way. APN 424-30-080. APN 424-30-080. Request
for Review PHST-24-022. Exempt Pursuant to CEQA Guidelines, Section
15301: Existing Facilities. Property Owner: ALG Homes, LLC. Applicant: Erik
Zang. Project Planner: Maria Chavarin.
RECOMMENDATION:
Consider a request for approval to construct exterior alterations (window and door
replacement) to a pre-1941 single-family residence on property zoned R-1:20 located at 17121
Wild Way.
BACKGROUND:
On November 20, 2024, the Committee conducted a preliminary review of the request
(Attachment 1) and recommended that the applicant:
• Confer with an architect that has experience with window repair and restoration on historic
homes to determine if repair and preservation of the existing historic metal windows is
possible. Improvement of the efficiency of the windows should also be considered. This
determination to be provided to the Committee for consideration at a future meeting.
DISCUSSION:
The applicant responded to the recommendations of the Committee by engaging Preservation
Architect Mark Hulbert to advise on the potential restoration of the existing steel windows and
doors and provide recommendations regarding any replacement. Attachment 2 is a letter from
Mr. Hubert providing background on the residence’s windows and doors. The letter opines that
replacement of the existing windows and doors is necessary rather than restoration. Mr.

DATE: February 21, 2025
Hubert provides a number of recommendations for the replacement windows and doors,
including:
• Replacement windows and doors should be aluminum or aluminum clad;
• Replacements should include exterior design and detailing similar to the originals;
• Units should be thermally glazed with simulated divided lites with slender exterior grids
to match existing;
• Unique windows, as noted in the letter, should be replicated; and
• Entire unit assemblies require removal and replacement.
The applicant has indicated to staff that they intend to implement all recommendations
included in Mr. Hubert’s letter. Photos of the existing condition of the structure are included as
attachment 3 to this report and update development plans are included as Attachment 4.
CONCLUSION:
The applicant is requesting approval for construction of exterior alterations (window and door
replacement) to a pre-1941 single-family residence (Attachment 4). The applicant responded to
the Committee’s guidance by engaging a preservation architect and indicating that they will
implement the architect’s recommendations. Should the Committee find merit in the request, it
should make the following considerations, and the recommendation would be forwarded to the
Community Development Director, and the project would be completed with a Building Permit.
The project would not return to the Committee.
CONSIDERATIONS:
A. Considerations
Sec. 29.80.290. Standards for review.
In evaluating applications, the deciding body shall consider the architectural style, design,
arrangement, texture, materials and color, and any other pertinent factors. Applications
shall not be granted unless:
For pre-1941 structures, the proposed work will neither adversely affect the exterior
architectural characteristics or other features of the property which is the subject of
the application.

DATE: February 21, 2025
B. Residential Design Guidelines
3.7.3 Match window materials to the architectural style and to the surrounding neighborhood
• Wood windows are common in Los Gatos. Wood is still the desired choice for styles that
traditionally used wood. However, today there are some window materials, such as vinyl
clad wood windows that are not noticeably different from wood at a short distance.
4.8.2 Building Materials
• Composite, synthetic, metal, vinyl, plastic or fabricated/imitation wood products, painted
brick or imitation used brick will generally not be approved. However, some exceptions may
be made on a case-by-case basis when the decision-making body determines that the
replacement is consistent with the appearance of the original material, and that a lay
person would be unlikely to discern the difference. The burden of proof will reside with the
applicant. Material samples, photographs, and specific locations where the material may be
seen in use will all assist in the evaluation of alternative materials.
4.8.4 Windows and Glass in doors
• Windows should be constructed of real glass, and window frames should be constructed of
real wood - not vinyl, metal, or plastic. Wood sashes may be vinyl or metal clad if the
window frame and dressing is designed consistent with the historic context of the building.

17121 Wild Way, Los Gatos Historic Window and Door Recommendations
The following report summarizes historic architectural considerations and recommendations for the
extant windows and doors of the subject residence.
Existing windows are traditional industrial steel units, mostly operating casements, several fixed, all
with true-divided lites, of which there are some 40 units. There are also 2 pairs of steel doors. Other
doors are hardwood plank at front, or painted wood with divided lites at side and rear.
In sum, multi-lite steel units, while traditional, are an unfortunate choice for residential construction,
as older single-glazed steel units are ultra-lean and lightweight, leak moisture and air excessively so,
at this approximately 100-year juncture, have minimal thermal effectiveness and challengingly high
maintenance requirements. At Wild Way, this reality is in clear evidence as even interior faces of
steel sashes have rusted.
As these steel doors and windows are challenging both in terms of the lack of thermal and
waterproofing qualities and resulting maintenance requirements, and as insulated windows and
doors are recommended for fire prevention, I firmly concur that replacement is needed. Towards
which, the following considerations and recommendations are intended to satisfy architectural and
historic architectural requirements:
1. As the existing units are metal, replacement exterior material should be similar so that the
exterior appearance is similar.
2. While new high quality thermally rated steel windows are available, they are by far the highest
cost option. While fiberglas replacement windows are also an option, the exterior material and
profiles would not match the existing historic.
3. Aluminum doors and windows are an alternative, whether full aluminum or aluminum exterior
clad, the latter the more residential and more available option.
4.Replace the existing windows (figs.4-5) with exterior aluminum clad units with exterior design
and details similar to the existing originals. Multiple manufacturers produce standard windows.
Yet, based on recent experience, only several provide custom details to effectively replicate
historic windows and doors – in particular exterior casings and muntins molded to replicate
historic profiles (figs.6-7). Such window and door manufacturers include Marvin (Ultimate series)
and Andersen (E-series), which are the recommended and equivalent replacement options (see
product literature https://www.dropbox.com/scl/fo/r00ni0he48lhhp2ss2v03/AB7UgDesWLIui_-
HCZEVfh0?rlkey=u94jll0xr7aqobb9si82q3u8p&dl=0).
5. The ornamental hardwood front door (fig.8) should be retained, repaired and refinished. Other
exterior doors (fig.9) should be replaced with aluminum clad units.
6. Replacement doors and windows to be thermally glazed with “simulated” divided lites and with
slender exterior grids (i.e., “muntins”) to match the existing.
7. Entire window and door assemblies require replacement, so complete existing assemblies,
including frames, require removal and replacement with thermal- and water-proofed assemblies.
8. Per attached photos (figs.10-12), a range of unique windows should be replicated to be similar to
the existing originals include:
•The living room bay window does not have molded casings but has flat casings, which
exterior appearance the replacement assembly should replicate.
