A multipurpose room might seem like a design decision from days of yore, but more and more people –– particularly in urban areas –– are living in less square footage. That comes as no surprise since doubling up on functionality is practical for both space and budget.

A space that can be easily re-adapted is the guest room, particularly one that is used only several times per year (such as when your old college roommate comes to visit).

Here are four ways to make alternate use of your guest room after your guests have checked out.

1. The Guest Room/Nursery
If needed, use your guest room as a nursery and when Aunt Brenda comes for a visit, move the baby into your room for the weekend. This inviting dual-purpose space is lovely enough for a newborn, or your most discriminating in-law.

2. The Guest Room/Office
One of the most practical solutions for a multipurpose room is a guest room and office in one. This modern take on a traditional layout –– with a temporary wall separating the spaces –– works beautifully and enables one person to catch some sleep while another is hard at work. The room also functions well as a home office. This design is perfect for a city apartment guest room.

3. The Craft Room/Guest Room
Clever built-ins and a sewing machine turn an extra sleep space into a project area. The uncluttered approach leaves guests plenty of room to sprawl. Pleasant and practical for work, play, or rest, this versatile guest room receives a good amount of natural light through the double window and skylight.

4. The Guest Room/Children’s Room
These clever built-in bunk beds are ideal for kids or teens. This cabin could very well be a second home, in which case you could move the children into your room (perhaps on folding cots) when you have overnight company. This space is also convenient for a family of four if you have a couple with children come for a stay.
