DISCUSSION:
The property is located east side of Wilder Avenue, between Bean and Nicholson Avenues
(Attachment 1). The applicant is requesting a preliminary review by the Committee for
construction of an addition to an existing single-family residence in the Almond Grove Historic
District (Attachment 4).
The following applicable excerpts from the Residential Design Guidelines are provided to
facilitate discussion relative to the proposed addition:
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 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 characteristic 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 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 structure only and should be subordinate
in terms of scale and detailing.
The project would require an Architecture and Site application for a request to exceed the FAR
standards. The residence would be approximately 2,764 square feet where 2,516 square feet is
allowed by the Town Code. The 256-square foot addition to the residence would fully enclose
an existing lanai sunroom that is located along the right elevation and is currently enclosed on
three sides and covered by the existing roof. The applicant is proposing to relocate the existing
painted, wood folding door system to enclose the space. The applicant states that the existing

DISCUSSION (continued):
doors are in keeping stylistically and materially with the existing doors on the residence
(Attachment 2).
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:
In historic districts, the proposed work will neither adversely 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.
B. Residential Design Guidelines
Sections 3.9 of the Town’s Residential Design Guidelines offers recommendations for
construction of additions to existing residences (Attachment 3).
CONCLUSION:
The applicant is requesting a preliminary review by the Committee for construction of an
addition to an existing single-family residence located in the Almond Grove Historic District.
The project would require an Architecture and Site application for a request to exceed the FAR
standards. The application would return to the Committee for a formal recommendation to the
deciding body.

LETTER OF JUSTIFICATION
TO: Town of Los GatosFROM: Jay Plett Architect
PROJECT DESCRIPTION:
This is a non-historic home in the Almond Grove Historic District.
The home has been remodeled recently with very beautiful custom folding doors. We propose to move the existing doors in photo A to the location shown on the Plans, Sheet A-1.
Photo B depicts other matching doors that were added to the home. The door style will remain consistent through out the home and are complementary to the Historic District.
Best Regards,
Jay Plett Architect

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
