Attached ADU concept visualization for design comparisonConcept visualization
Visual reference only. Final architecture, openings, materials, structure, room arrangement, and site placement require project-specific work.

Use the concept correctly

Inspiration can start the conversation. The property must shape the result.

Useful for comparison

Compare roughly 600 sq ft, 1 bedrooms, 1 bathroom, and a contemporary addition direction.

Not evidence of fit

The image does not establish setbacks, lot coverage, access, utilities, hazards, fire separation, structural design, or local approval.

Not a price or schedule

Site conditions, professional scope, agency review, selections, and written project documents control the final proposal.

Not a completed project

No construction history, customer result, rental income, property-value increase, or project performance is claimed here.

Canonical model footprints

Compare this direction with a defined starting footprint.

Model dimensions are stable inputs for preliminary fit testing. They are not floor plans or proof that the model is permitted on a property.
