Studio apartments are not really apartments. They are a single room that you live in and you’ll be lucky if you get any space. That means that you need to use what little space you have to the highest possible efficiency.
Get shelves. Lots of shelving will make your tiny space more livable. If you can get shelves that reach the ceiling then all the better. If you can’t then get wall shelves and fill up the space.
Make use of the combination of form and function known as daybeds. These are beds that double as couches. This is nothing like the pullout couches that we have all spent a few nights tossing and turning on. These are designed to be comfortable. Day beds come in a lot of designs and styles that will be guaranteed to fit into your home.
Along with full size daybeds you can consider bunk beds. Since you don’t have an extra room to turn into a guest room you are going to need someplace that guests can sleep. Hideaway beds are another great option but they are a bit harder to manage and less common. If you have the technical skill you can create a false wall that hides a hideaway bed and turn the rest of it into cabinets and shelving. In many studio apartments you will find exposed brick. If you let this show through your false wall when the cabinets are open or the bed is down you have created a really cool design element that people will talk about. If you want to stay simple then the daybeds are still your best bet.
Think about levels. If you plan on living there for a long time and the studio has a very high ceiling you can build levels to create different spaces and, in essence rooms. I know I am talking about a lot of handyman jobs but they are really the best for making the most out of any space, Studio or otherwise.
Living in a studio is tough. Especially when you have an eye for design and want your living pace to reflect that. If you devote a little time and effort to your apartment you can turn it into someplace really worth showing off.
