ADU Design Shaped Around Your Sierra Madre Home and Garden Setting
A secondary residence can add meaningful new living space while preserving the landscape, privacy and residential character already established on the property. We develop the ADU around those relationships rather than treating the backyard as an empty site.
Garden-Led Property Planning
Existing trees, planting, patios and pathways can help guide the ADU footprint so the new residence becomes part of the garden composition rather than displacing the outdoor spaces that matter.
Privacy, Light & Orientation
Entrances, windows and primary living spaces can be positioned to create comfortable separation while maintaining natural light and meaningful visual connections to the landscape.
Architecture With a Quiet Presence
Scale, roof form, materials and opening proportions can connect the ADU to the existing Sierra Madre home without allowing the new building to dominate the property.
Developing the Residence From Property Study to Architectural Detail
The design package coordinates site relationships, interior planning, exterior architecture and three-dimensional studies so the proposed ADU can be evaluated as part of the complete residential setting.
Property Planning & Building Placement
Site drawings establish the ADU in relation to the existing home, landscape, circulation, outdoor areas and changes in grade where they influence the property.
Floor Plans & Residential Flow
Interior plans develop room proportions, circulation, storage, furniture relationships and openings to create a comfortable and efficient independent residence.
Exterior Elevations & Architectural Character
Elevations refine massing, rooflines, exterior materials and glazing to establish a measured architectural relationship with the primary residence and garden setting.
Sections & Vertical Relationships
Building sections clarify ceiling heights, roof geometry and vertical relationships that help explain the spatial character of the ADU and how it sits within the property.
3D Modeling & Property Studies
Three-dimensional studies help evaluate exterior massing, materials, openings and the visual relationship between the new residence, existing home and surrounding landscape.
Architectural Plan Coordination
The architectural package can be coordinated with consultant information and supporting project documentation as the design advances toward later project phases.
From Existing Property Character to a Carefully Integrated Residence
The process begins with the existing home, garden and intended use, then develops placement, privacy, interior planning and architectural character around the relationships already present on the property.
Home & Landscape Review
We study the primary residence, planting, outdoor areas, access, privacy and intended use to understand what the ADU should preserve and what it should add.
Placement & Garden Strategy
Building footprint, entrances, orientation and relationships to patios or garden areas are explored together as part of the initial property concept.
Architectural Development
Floor plans, roof form, exterior proportions, glazing and materials are refined together so the new residence feels complete without overpowering its setting.
Coordinated ADU Plans
The selected direction advances into architectural drawings that clearly communicate the residence for the next stage of the project.
While Adding Something New
A Sierra Madre ADU can introduce a complete new residence without erasing the qualities that make the original property distinctive. Landscape, scale, privacy and architecture can allow the addition to feel established from the beginning.
Architectural Character That Respects Home, Garden and Scale
The ADU can closely complement the primary residence or reinterpret its architectural language with cleaner detailing. The strongest direction maintains proportion, material quality and a thoughtful relationship to the landscape.
Craftsman
Expressive rooflines, warm materials and carefully proportioned details can create an ADU with an established residential character and a strong relationship to garden space.
California Contemporary
Simplified forms, natural finishes and strong outdoor relationships can create contemporary architecture that remains warm, understated and residential.
Mid-Century Modern
Horizontal proportions, warm materials and broad connections to garden areas can create a relaxed California modern residence.
Modern
Clean massing, restrained detailing and carefully positioned openings can create a contemporary residence with a quiet architectural presence.
Traditional
Familiar roof forms, balanced elevations and carefully scaled details can create an ADU that relates naturally to an established primary residence.
Transitional
Traditional proportions can be paired with simplified detailing and updated materials to create architecture that feels timeless while remaining current.
The architectural direction can respond to the existing Sierra Madre residence, mature landscape and the balance of privacy, garden character and architectural continuity you want the ADU to create.
Adding a New Residence Without Losing the Garden Around It
The strongest ADU design can create a complete new living environment while preserving the outdoor spaces and landscape that give the property its character. Architecture, planting and circulation should feel planned together rather than layered on separately.
Mature Landscape as Part of the Plan
Existing trees, planting and garden areas can help shape the placement of the residence, create natural privacy and preserve a sense of depth around the property.
Outdoor Rooms Between Buildings
Patios, garden paths and smaller landscaped spaces can create useful transitions between the primary home and ADU rather than leaving the space between them undefined.
Scale That Respects the Main Home
Building mass, roof form and exterior proportions can give the ADU a complete architectural identity while maintaining an appropriate relationship to the primary residence.
Without Erasing the Garden
A thoughtfully designed Sierra Madre ADU can expand the way the property supports everyday life while keeping landscape, privacy and architectural character intact. The new residence should feel like another layer of the property rather than a replacement for what was already there.
