I nearly laughed, then sketched a layout that actually worked. Small spaces embarrass you into cleverness, and that’s how I learned to treat every square foot as a feature, not a limitation.1. Open-plan living with zoned furnitureOpen-plan feels like a cliché until you live in 600–800 sq ft. I recommend arranging furniture to create zones: a low sofa with a slim console behind to separate living and dining, and a rug to anchor the sleeping corner. Advantages: visually expands space and improves daylight flow. Challenge: you’ll need clever storage to hide clutter; I usually specify multifunctional pieces to avoid visual noise.save pin2. Built-in storage around the bedsIn one ADU I designed, we wrapped a twin daybed with drawers, a narrow wardrobe, and a shelf niche — the client gained storage without sacrificing walkways. Built-ins maximize every inch and give a clean, custom look. Downsides: higher upfront carpentry cost and less flexibility for future reconfiguration, but the payoff in usable space is huge.save pin3. Pocket doors and sliding solutionsPocket doors saved a couple of meters in a layout I worked on where a standard swing door would have blocked a closet. Sliding bathroom doors and a barn-style bedroom divider keep circulation free. They can be slightly pricy and require precise installation, yet the spatial gains and sightline continuity are worth it.save pin4. Compact kitchen with smart appliancesI often specify a galley kitchen with stacked appliances and a slim island that doubles as prep and dining. You can fit full function into a narrow footprint by choosing two-burner cooktops, under-counter refrigerators, or a combi washer-dryer. The trade-off: smaller appliances mean adapting cooking habits, but you keep social space intact.save pin5. Flexible second bedroom / office comboThe second bedroom in many ADUs ends up as a catch-all. My go-to is a fold-down bed or a high-sofa bed and built-in desk so the room switches between guest sleep and productive day use. Pros: maximum utility; cons: guests may notice office dust unless you create concealed storage for work items.If you want to experiment with room arrangements quickly, try a reliable room planner that helps test layouts before you commit to carpentry.save pinTips 1:Budget-wise, prioritize built-in storage and door solutions early; they’re harder to change later. Opt for LED lighting and mirrored surfaces to amplify light. For materials, go for durable, low-maintenance finishes in high-use areas like kitchens and bathrooms.save pinFAQQ: What is an ideal size for a 2-bedroom ADU?A: Many 2-bedroom ADUs range from 500 to 800 sq ft.
