A foyer or entryway is typically a formal landing area for guests, located at the primary entrance of a home. It is often more formally decorated and connects directly to the main living space. In contrast, a mudroom is a more casual, utilitarian room, usually leading in from a secondary entrance like a garage or the side or rear of the house. It serves as a space for residents to remove shoes and outerwear to keep mud, dirt, and water out of the main home.

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.

If you’re on a tight budget, the least expensive material you can buy for DIY closet shelves is chipboard, a.k.a. particle board. This inexpensive material is made from a pulp of sawdust, resin, and glue that’s pressed together under high temperature and pressure. As you can imagine, it’s not very sturdy and might buckle under your blue jean collection, so you should only use it if you’re storing very light items. 

The time it takes to build a closet varies widely depending on the project's size, complexity, and level of customization. On average, construction can take anywhere from a few days to two weeks.

A simple reach-in closet might be completed in less than a day, while a more complex walk-in closet could take one to two days or more. A typical project often falls in the 2-to-5-day range. However, a large, highly customized walk-in closet that requires structural changes, like moving a load-bearing wall, will take significantly longer.

A professional contractor can provide the most accurate time estimate for your specific project. If you are planning a DIY build, it is best to budget additional time.
