Step 5: Design strategies that make an ADU feel bigger

By Cali Dream Construction | January 09, 2026 | San Diego

Square footage is only one part of comfort. Great ADUs feel spacious because of design.

High-impact design moves:

• open main living area (kitchen + living combined)

• large windows in the right places (light without sacrificing privacy)

• built-in storage (so the unit stays uncluttered)

• simple, cohesive material palette (makes the space feel calm)

• outdoor extension (small patio, deck, or courtyard)

Even a compact ADU can feel premium when the storage and lighting plan is thoughtful.
