ADU Design Developed Around Your Los Angeles Property
Skalwest provides ADU design services in Los Angeles for homeowners who want more than a generic plan placed in the backyard. We develop the ADU around the property, the existing residence, the way the new space will be used, and the architectural relationship between the two buildings.
The design process begins by understanding the property rather than starting with a predetermined building shape. The location of the main house, garage, yard, trees, patios, pools, neighboring properties, utility areas, access, and grade can all influence the placement and orientation of the proposed ADU.
An ADU floor plan should do more than fit a required number of rooms into a limited footprint. We consider how someone enters the residence, moves between spaces, arranges furniture, uses the kitchen, accesses storage, receives natural light, and connects with outdoor areas so the layout feels comfortable rather than compressed.
The ADU does not have to duplicate the main house, but the two structures should feel intentionally related. Roof geometry, exterior materials, window proportions, wall openings, colors, landscape, and architectural details can be developed to create continuity while giving the ADU its own character.
Privacy is not simply a matter of distance. Window direction, entry placement, planting, courtyard walls, high windows, patios, and the orientation of living spaces can help the ADU receive daylight while reducing direct visual overlap with the main house and neighboring properties.
We do not see the ADU as an isolated object at the back of the lot. The space between the ADU and the main residence is part of the design as well. Paths, gardens, courtyards, patios, landscape screens, and shared outdoor areas can help the entire property feel more deliberate.
Architectural Plans for Your Los Angeles ADU
ADU architectural plans translate the design into a coordinated set of drawings. The exact package depends on the project, but it typically develops the relationship between the site, floor plan, exterior architecture, building sections, important details, and additional information needed as the project advances toward permitting.
Site planning communicates how the ADU sits on the property in relation to the primary residence, property lines, access, existing structures, outdoor spaces, and other relevant conditions. It also provides the framework for understanding how the proposed building relates to the larger lot rather than viewing the floor plan independently.
The floor plan develops the internal organization of the ADU. Room sizes, doors, windows, kitchens, bathrooms, storage, furniture relationships, circulation, and connections to outdoor areas are refined until the residence works spatially as well as architecturally.
Exterior elevations help develop the ADU as a complete building rather than only an interior layout. They show the relationship between walls, rooflines, windows, doors, exterior materials, heights, and architectural details while allowing the proportions of each facade to be evaluated.
Building sections help explain conditions that cannot be fully understood from a floor plan or elevation alone. Ceiling heights, roof relationships, floor levels, openings, vertical circulation, and key architectural conditions can be developed through sections and details as the design becomes more resolved.
LADBS documentation for ADU plan review references floor plans, building elevations, cross sections, foundation information, roof framing, energy documentation, and related project information. The exact documents required for an individual ADU depend on the design and property, so the drawing package should be coordinated around the actual project rather than treated as a fixed checklist.
From Property Review to Completed ADU Design
A clear design process allows major decisions to be made in the right order. Instead of immediately producing permit drawings, we first understand the site and project goals, develop the layout and architectural direction, refine the design, and then coordinate the drawing package.
We begin by reviewing the property and understanding what the homeowner wants the ADU to accomplish. Existing structures, lot configuration, outdoor areas, grade, neighboring conditions, access, and other site-specific factors help establish the opportunities and limitations that should guide the design.
The early concept establishes where the ADU belongs, how large it should be, how the rooms relate to one another, where the main openings should occur, and how the residence should connect to the yard. This is where major planning ideas can be explored before too much detail is developed.
Once the general direction is established, the project becomes more architecturally specific. Room proportions, windows, doors, roof forms, materials, ceiling conditions, exterior elevations, storage, and important details are refined so the ADU begins to read as a complete residence.
The developed design is translated into a coordinated architectural drawing package. Depending on the project, the architectural plans can then be coordinated with structural engineering, energy documentation, and other consultant or property-specific information required as the ADU advances toward City review and construction.
Three-dimensional design can be used throughout the process to evaluate building scale, exterior form, roof geometry, materials, openings, and the relationship between the proposed ADU and the existing property. It is particularly useful before important architectural decisions are finalized because the residence can be understood spatially rather than only through two-dimensional drawings.
A plan set should document a resolved architectural idea, not replace the design process. Developing the site relationship, floor plan, proportions, exterior form, light, privacy, and materials first helps the later drawings communicate a project that has already been considered as a complete residence.
Los Angeles also maintains an ADU Standard Plan Program. LADBS explains that approved plans can simplify part of the plan-check process, but the City still reviews site-specific zoning and foundation conditions. A custom ADU design provides a different approach: the residence is developed specifically around the property, homeowner, architecture, and intended use from the beginning.
Designing an ADU That Belongs on the Property
Architectural style is more than choosing exterior finishes. Roof proportions, wall composition, openings, materials, details, landscape, and the relationship between indoor and outdoor space can all be developed together so the ADU feels intentional rather than added as an afterthought.
Modern ADU design can use simplified geometry, larger openings, controlled material palettes, clean rooflines, and strong connections to outdoor areas. The goal is not simply minimalism, but clear proportion and carefully considered architectural composition.
A mid-century-inspired ADU can use low roof forms, extended overhangs, wood or warm-toned materials, horizontal window compositions, and direct connections between living areas and landscape. These elements can work especially well with existing Los Angeles homes from the mid-century period.
Traditional architecture can be interpreted without becoming overly decorative. Stucco walls, tile roofs, arches where appropriate, carefully proportioned windows, deep openings, eaves, and familiar residential forms can help the ADU relate naturally to an older primary home.
A contemporary or transitional ADU can combine familiar residential forms with simplified detailing, larger glazing, natural materials, and a more restrained palette. This approach can work well where the main house has an established character but the homeowner wants the new residence to feel current.
The ADU does not need to look identical to the primary residence. Architectural compatibility can come from proportion, roof geometry, window rhythm, material relationships, landscape, and scale. A carefully considered contrast can sometimes feel more intentional than trying to imitate the existing house exactly.
Our role is to develop the ADU as a piece of residential architecture: understand the property, organize the floor plan, establish the architectural character, visualize the design, and translate the selected direction into a coordinated set of architectural drawings for the next stages of the project.
