Building Design for your property
Building Design for your property
Building design begins with the way a space needs to work. A useful brief connects people, rooms, activities, light, privacy, outdoor areas, and budget priorities. It also identifies which aspects of the existing property should remain and which need to change.
20 years of ADU expertise
The design should develop at the right level for each decision. Compare concepts while major changes are still manageable, then refine the selected option with the technical disciplines and documents required for the next stage. Clear decision points help avoid repeatedly redesigning an already detailed package.
Building Design for your property
Discuss intended use, room needs, daily routines, future changes, visual preferences, and budget expectations. For an existing home, identify what currently works and what does not. Define priorities so alternatives can be compared against more than appearance.
Trust the process, love your ADU
Consider the building position, arrival, circulation, daylight, privacy, outdoor use, and known constraints. Use reliable information about existing conditions. Identify professional inputs needed to resolve boundaries, structure, or other site-specific questions.

Building Design for your property
ADU construction involves planning, permitting, and building a self-contained living space on a residential property , adding value, flexibility, and income potential without buying new land. In California, ADUs now make up about one in six new homes, reflecting their growing role in solving the state’s housing shortage.
Building Design for your property
Start with how much independence and space the household needs. A reconfigured home, an addition, and a separate dwelling solve different problems. Compare their implications before deciding which project type deserves detailed design.
Building Design for your property
An inspiration image can guide materials or atmosphere, but it does not establish a workable floor plan. Review storage, circulation, privacy, daylight, and maintenance alongside the desired appearance.
Building Design for your property
Identify the features that matter most and the decisions with the greatest scope implications. Keep optional features visible so they can be discussed deliberately. A clear priority list makes design tradeoffs easier when estimates develop.

Your top ADU questions answered
Answers to your most common ADU building questions.
Uni Construction lists ADU building design among its services. Share the site and household brief so a custom layout can be considered against the property and required documentation. A custom concept still needs technical coordination and approvals.
They are distinct professional descriptions. Your agreement should identify the actual professionals, their roles, and any required licenses or stamps for the proposed work. Do not assume that a service label replaces the project’s professional requirements.
Share the complete material, its status, and permission to use or modify it. We can discuss the remaining design work and technical inputs. Confirm ownership, responsibilities, and the extent of revisions before continuing.
Ask for a written scope covering the site review, layout options, exterior design, drawings and coordination needed for your project. Identify who handles engineering, permit responses and revisions. Bring examples of rooms you like, but also explain your storage, privacy and everyday access needs so the design brief is practical.
The appropriate team depends on the proposed work and the professional services required for it. Ask who is responsible for design and which licensed professionals will provide any required architectural or engineering services. Uni Construction can discuss the design and coordination scope without assuming every project needs the same team.
