You might think that good bathroom design means expensive tiles or a rain shower head. Those things help, but what matters more is where you put your stuff. If your bathroom has no built in storage, every towel and bottle ends up on the floor, and that makes the room feel smaller than it is. I recommend adding a narrow floor to ceiling cabinet next to the toilet, even if you have to sacrifice a few centimeters of walking space. Then, in the living area, choose furniture that hides bedding. A bed with storage is not a luxury, it is a necessity when you only have one closet. The combination of a slim bathroom cabinet and a bed with storage will free up your entryway and your living room, so you can host without tripping over pillows. And when no one visits, which is most of the time, you are not living with a half unfolded sofa bed in your f

Storage is the real monster in small bathroom design. The standard vanity cabinet with two doors looks neat, but open it and you find a black hole where bottles topple over every time you pull out the toothpaste. I ripped mine out and built a shallow drawer unit instead. Only twelve centimeters deep, but that is enough for deodorant, floss, and a backup toothbrush. Above the toilet, I installed a wall-mounted cabinet with a bifold door so it does not hit my head when I stand up. And I finally stopped pretending I needed a bathtub. The claw-foot tub the previous owners left was taking up space I could use for a proper shower with a built-in bench. That bench holds a caddy, but also a place to sit while drying my feet. Every square inch earns its liv

The biggest mistake I see in hallway design is ignoring the floor. People pick a runner that is two centimeters too narrow, and the hallway suddenly looks like a bowling lane. I went with a wool runner that sits exactly 10 centimeters from each wall, creating a defined path that guides the eye forward. Underneath it, I laid a rubber underlay with a nonslip grip, because the last thing you want is a rug sliding under a pull-out sofa leg as someone shifts their weight. The walls got a warm off-white with a matte finish, and I mounted a full-length mirror at the far end to bounce light from the single overhead fixture. Suddenly, that narrow tunnel felt wider, even with a piece of velvet upholstery taking up a third of the wi

Let me give you a concrete example of how the two spaces can work together. In a recent project, we had a 50-square-meter flat with a bathroom that felt like a closet within a closet. The owners wanted a double vanity, but there was no room. So we put in a single wide vessel sink with a generous counter to the right. That counter became the catch all for toiletries and a coffee station for guests. On the living room side, we chose a sofa bed with velvet upholstery in a deep teal. Velvet upholstery is forgiving of spills and pet hair, and it makes the sofa feel like furniture, not a bed that happens to fold. The pull-out sofa had a storage compartment under the seat where we kept a spare duvet. When guests came, we pulled out the bed, grabbed the duvet from underneath, and grabbed the pillows and foam topper from the platform bed in the master. The bathroom remained because the towels and guest soaps sat on that counter, and the bedroom storage held everything else. The whole operation took five minu

Designing this attic forced me to stop thinking about what a bedroom should look like and start thinking about what it does. It does not need a bed frame with a headboard. It needs a machine that transforms from seating to sleeping seamlessly. It does not need a dresser. It needs a bed with storage that hides the clutter of extra linens. The sofa bed with its 16 cm foam mattress and solid slatted frame is the workhorse of the space. When I have no guests, the room functions as a quiet reading nook with my two little shelves and a small rug. When my sister visits, it becomes a cozy bedroom in under a minute. That flexibility is what attic design is really about. It is not about grand gestures. It is about making the square footage you have perform like something twice its s

One more thing about the click-clack mechanism. Some people worry it is flimsy, and cheap versions can break after a year. Look for a frame with a steel mechanism and a warranty of at least five years. The slatted frame should be made of beech or birch, not pine, because pine flexes too much and will make the foam mattress sag within a season. I have tested three different click-clack sofas in my own home over the past decade, and the one with the steel mechanism and a medium firm foam mattress is still going strong. The foam mattress itself should be at least 12 centimeters thick for a night a week use. If you can, buy a separate topper for guests so your sofa foam does not wear out prematurely. Then store the topper in your bed with storage. That single swap will double the lifespan of your sofa
