A few simple updates and minor tweaks are all it takes to transform your space from meh to magnificent.

And it doesn't need to break the bank.

Interior designer Max Humphrey believes every stylish room only needs three things: books, layers, and art. “They're the single most important design accessory there is,” he says. “Layers, because minimal rooms are boring, and art, because it adds personality and says something about you that furniture never can. And it doesn't have to be expensive art.”

We quizzed Humphrey, along with Krista Schrock and David John Dick, co-founders of DISC Interiors, for more affordable updates you can carry out in a snap.

Living room

If you're looking for a low-cost upgrade with high impact, Humphrey says to add a bar. “There are tons of bar carts out there, new and vintage, or just use the top of a sideboard and some cool trays,” he says. “They're fun to style with vintage glassware, monogrammed napkins and colorful bottles; your friends will love it too.”

Humphrey says moving your furniture away from the wall will really give it that transformative effect on a dime. “You can get that designer-y look and create an intimate conversation space by floating everything off the wall,” he says. “Even just a few inches.” If you really want to define the space, Humphrey recommends buying an area rug that's big enough to fit all the furniture on. You'll be amazed how this simple move makes a massive difference.

But what if your furniture is looking lackluster? It's not always convenient to replace these big-ticket items, but Dick and Schrock say you don't have to. Just reupholster your existing pieces in new fabrics and textiles to introduce color or pattern in a new way.

Dining room

The dining room is the jewel of the home, where we feast every night, entertain friends and families and catch up on the day's events. That why the room needs to be special. The quickest, most cost-effective way is to change out the overhead lighting.

“Apartments always come with terrible pendant lights,” Humphrey says. “You can find a cool new or vintage pendant or chandelier at great prices, and it's not hard to swap them out.”

This simple switch applies to renters too.

“Just keep the old pendant in a closet and reinstall it before you move out,” he says. “You can take the new one to your next place. I've done this at every single one of my apartments, and it makes such a difference. Then add a dimmer switch for $10 from the hardware store.”

If you're not sure how to install one on your own, Humphrey says he looks up YouTube tutorials, but if you're still not confident, “just tip your superintendent a few bucks to do the work for you.”

Bathroom

While re-tiling is on the long-term agenda, we have a couple of thrifty solutions to ramp up that style dial fast.

“Buy yourself some cool embroidered hand towels,” Humphrey says. “Don't let your guests dry their hands on the soggy bath towels hanging over the shower curtain rod. There are tons out there, or search eBay for vintage French linen ones with monograms. Don't worry if they're not your initials; it'll just add mystery.”

Need an update and the illusion of a little more space? Schrock and Dick say you can have both with the installation of a decorative mirror.

Bedroom

Sleep is vital to our sanity, so the bedroom needs that comfort factor, with a dash of chic for the sweetest of dreams. If yours is looking a little nightmarish, Schrock and Dick say a quick bedding upgrade is all it takes to ditch those bad vibes and introduce new textures and color.

“Early in our career, one of our clients told us she changed her pillows with the seasons, and we love this idea of bringing new life into a room simply by rotating linens and blankets to freshen up a room,” they say. “For bedding, decorative blankets and pillows are simple updates that make a big difference.”

Entryway

As the first thing everyone sees when they enter, your foyer deserves a little love. While there are several ways to spruce up your entryway, our experts agree that wallpaper is one of the most transformative.

“I've bought pre-pasted removable wallpaper online for very little money and installed it myself,“ Humphrey says. “It's not hard to do at all, and you can get a totally custom entry like the ones you see and love in design magazines.”

Humphrey says installation is easy too. Just dunk the paper in the bathtub to activate the glue, and then stick it on the wall and trim to fit. “It's nerve-wracking at first, but you get the hang of it,” he said. “If you're in a rental, it's really easy to peel off so you don't get dinged for your security deposit.”

Schrock and Dick concur. “Wallpaper is visual eye candy, and it can really transform how a room feels,” they say.

Kitchen

While the obvious upgrade to any small kitchen is to add a rug, Humphrey says greenery is the way to go. “Houseplants are cheap and make every room brighter. If you're lazy like me, you won't need to go far to water them since your sink is right there. I like using cool baskets as containers and just dropping the plant in there so I don't have to deal with repotting them.”
