Historic District on property zoned R-1D:LHP located at 201 Wilder Avenue.

BACKGROUND:

BACKGROUND (continued):
Almond Grove Historic District. The existing single-story residence features a mix of wood and
vinyl windows, stucco siding, board and batten siding located in the gable ends, and
composition roof shingles. Additionally, the residence includes a mixture of window and door
types. The applicant has indicated that some of the windows may be original, but many have
been replaced as evidenced by dual-glazing and contemporary materials.
DISCUSSION:
The applicant proposes an addition and exterior alterations to the residence. The proposal also
includes modifications to an existing detached accessory structure (garage/accessory dwelling
unit). The proposed addition to the residence would be located at the rear and include exterior
materials and a roof pitch to match the existing residence and would have a lower ridge height
than that of the existing residence. The applicant also proposes to modify the exterior of the
existing residence by squaring the arched openings located at the entry porch and above the
windows at the living/dining room located along Nicholson Avenue. Additionally, all existing
windows would be replaced with metal-clad wood windows. The existing original trim would
remain or replaced in kind if damaged. All new wood trim would match the existing.
Proposed exterior modifications to the existing accessory structure include:
• Removal and replacement of the north wall, which encroaches on the neighboring property;
• Replacement of existing wood shingle siding with stucco to match the residence;
• A new composition roof to match the residence; and
• A new porch.
CONCLUSION:
The applicant is seeking a recommendation from the HPC to the Community Development
Director that the proposed addition and exterior alterations are consistent with the Town Code
and the Residential Design Guidelines and are compatible with the neighborhood. Should the
HPC find merit in the request, the application could be approved by the Community
Development Director and the project would not return to the HPC.

CONCLUSION (continued):
arrangement, texture, materials and color, and any other pertinent factors. Applications
shall not be granted unless:
In historic districts, the proposed work will neither adversel y affect the exterior
architectural characteristics or other features of the property which is the subject of the
application, nor adversely affect its relationship, in terms of harmony and
appropriateness, with its surroundings, including neighboring structures, nor adversely
affect the character, or the historical, architectural or aesthetic interest or value of the
district.

Residential Design Guidelines 33
Town of Los Gatos
BUILDING DESIGN3
3.8.3 Use traditional detailing
•Treat openings in walls as though they were constructed of
the traditional material for the style. For example, be sure to
provide substantial wall space above arches in stucco and
stone walls. Traditionally, wall space above the arch would
have been necessary to structurally span the opening, and
to make the space too small is inconsistent with the archi-
tectural style.
•Openings in walls faced with stone, real or synthetic, should
have defined lintels above the opening except in Mission or
Spanish Eclectic styles. Lintels may be stone, brick or wood
as suits the style of the house.
•Treat synthetic materials as though they were authentic.
For example, select synthetic stone patterns that place the
individual stones in a horizontal plane as they would have
been in a load bearing masonry wall.
•Select roof materials that are consistent with the traditional
architectural style (e.g., avoid concrete roof tiles on a Crafts-
man Style house.)
3.8.4 Materials changes
•Make materials and color changes at inside corners rather
than outside corners to avoid a pasted on look.
3.9 ADDITIONS/ACCESSORY BUILDINGS/SECONDARY
UNITS
•Site additions in the least conspicuous place. In many cases
this is a rear or side elevation - only rarely is it a rooftop.
•The existing built forms, components and materials should
be reinforced. Heights and proportions of additions and
alterations should be consistent with and continue the
original architectural style and design.
•Additions should be subordinate, and compatible in scale
and proportion to the historically significant portions of
the existing structure.
•When an addition or remodel requires the use of newly
constructed exterior elements, they should be identical in
size, dimension, shape and location as the original, and
Use stone or wood lintels over
openings in stone walls
Additions, accessory buildings and secondary
units should match the form, architectural
style, and details of the original house

should utilize the same materials as the existing protected
exterior elements.
• When an addition necessitates the removal of architectural
materials, such as siding, windows, doors, and decorative
elements, they should be carefully removed and reused in
the addition where possible.
• The introduction of window and door openings not char-
acteristic in proportion, scale, or style with the original
architecture is strongly discouraged (e.g., sliding windows or
doors in a structure characterized by double hung windows
and swinging doors).
• The character of any addition or alteration should be in
keeping with and subordinate to the integrity of the original
structure.
• The amount of foundation exposed on the addition should
match that of the original building.
• Do not add roof top additions where the roof is of historic
significance.
• Second floor additions are discouraged in neighborhoods
with largely one story homes. If horizontal expansion of
the house is not possible, consider incorporating a second
floor addition within the roof form as shown in the example
to the left.
• Second floor additions which are not embedded within the
roof form should be located to the rear of the structure.
• The height and proportion of an addition or a second story
should not dominate the original structure.
• Deck additions should be placed to the rear of the struc-
ture only, and should be subordinate in terms of scale and
detailing.
• New outbuildings, such as garages, should be clearly subor-
dinate to the main structure in massing, and should utilize
forms, materials and details which are similar to the main
structure.
• Garages should generally be located to the rear of the lot
behind the rear wall of the residence. One car wide access
driveways should be utilized.
Original structure
Addition incorporated into the roof
successfully adds space while respecting the
integrity of the existing house and the scale of
the neighborhood
Placing a two story addition to the rear can
minimize its impact on the historic resource
and the scale of the neighborhood
