Tiny house living requires creative solutions to the one biggest issue: space. Many people in tiny houses find life most manageable if they practice minimalism. Eliminating excess items and clutter makes the living space feel bigger, which can be a significant mood booster. It can also be challenging to get utilities arranged for a tiny house, and building and zoning codes can and often do present unique challenges to overcome. 

Walk-in closets are always the biggest and can easily be more than 100 square feet. Primary bedroom closets, even if not walk-ins, are the second largest category in most homes and sit between 30 and 80 square feet. Linen closets, utility closets, and built-in closets are smaller and, depending on their usage, tend to be between 10 and 50 square feet.

Yes, adding a built-in or custom closet generally increases your home's value and makes it more attractive to potential buyers. A well-designed closet adds utility, organization, and a touch of luxury, which are appealing selling points. Most homeowners see a return on investment (ROI) of 50% to 60%; for example, a custom closet can add about $1,000 to your home's value on average. The specific ROI depends on the type, with custom walk-in closets typically providing more value than reach-in closets. However, to maximize value, ensure the closet doesn't significantly detract from the room's usable square footage. Converting an entire room into a closet can actually lower your home's value. Similarly, using overly lavish materials may not recoup their cost. A good strategy is to add a closet that takes square footage from a non-living area, such as a garage, to create a mudroom closet.

Plywood, MDF (medium-density fiberboard), and solid wood are all popular options for closet shelving. Plywood and solid wood are sturdy and ideal for extended shelves or heavy items. MDF is a budget-friendly choice for light to moderate storage, but it can sag under heavy weight if not adequately supported. Wire shelving is another alternative that allows airflow, making it especially useful in humid spaces such as laundry rooms or basements.
