From chic lofts to colorful art galleries, our venues run the gamut and can fit any budget and aesthetic idea you have.

1. Set up a birthday photo booth to snap special memories

A birthday photobooth can double as an adorable party decoration and a way to capture memories of your big event. You can decorate your photo booth with colorful backdrops and interactive props.

For inspiration, check out the staging at Peerspace photo studio rentals, like these interactive photobooth rooms in Las Vegas. This fully-equipped space lets you take endless photos and prints in several decorative spaces that use immersive technology to transform your photo sesh.

Another perk that comes with using Peerspace to rent spaces? You can read genuine reviews from past renters before booking! Here is one example for this Vegas photo booth studio: “Awesome space! Loved the layout! Host was very friendly & extended help if we needed anything! I would definitely recommend and book again!”

2. Use faux greenery for a lush look 

Greenery is an interior designer’s go-to trick to brighten up a room. You can use this design tip to heighten your birthday party decoration ideas, too.

Check out the way this luxury event space in Detroit, MI uses grass walls and neon signs to add color and texture to the space. While these design touches make a chic interior statement, the grass walls would also provide a more sophisticated take on streamers for your birthday décor. 

3. Create a balloon arch 

Let’s kick off the adult birthday party decoration ideas with a classic party décor piece. Balloons are a birthday party staple. The more balloons the better in our book! So why not make a decorative balloon arch at your adult birthday party?

You can keep your arch feeling grown-up by using a balanced color scheme, like the pink, gold, white, and orange balloon arch at this classy TriBeCa/SoHo event space loft in New York City, NY. The venue itself makes a perfect setting for an adult’s birthday party, offering space for 75 guests, abundant chic decor, and a host that goes out of his way to help bring your vision to life.

4. Bring on the beads 

Beads are an often underutilized option for birthday decoration ideas for adults. But to us, they are so fun and offer so much customization. Plus, they remind us of Mardi Gras and the epic parties that go on there!

Just check out the hanging beads at this New Orleans flex space. It’s subtle, yet brings a pop of color to the room and helps set a welcoming atmosphere. Check out what a Peerspace reviewer shared after booking a birthday party here: “The Particular is a spectacular venue for any social gathering you are considering. I fell in love with its unique & comfortable decor which lent itself perfectly to our “Speakeasy” theme. Everything that one could need to make guests happy is there, but even if you should need something unusual, such as a mirror ball, Cam will do her best to make it happen.”

5. Add a dash of childhood wonder 

Just because you’re an adult doesn’t mean your party décor has to be grown-up. Sometimes adding a splash of childhood wonder to your décor can help create an immersive party atmosphere.

Check out the way this IRL dollhouse in Los Angeles uses pastel colors, faux flowers, and chandeliers to create a cute and sweet design statement. The décor here isn’t totally innocent, which helps create an edgier “grown-up” vibe that’s completely to die for. The fact that it’s been featured in Vogue tells us something!

6. Disco balls make all the difference 

Lighting can help you set the overall mood and tone at your party. So, throwing a disco ball into your party décor can help you create a retro and vibrant party environment.

You don’t need to look far and wide for a venue with a disco ball, either. Just check out Peerspace! For instance, this 1920s contemporary venue and art gallery in Dallas, TX uses a disco ball and professional lighting to evoke groovy effects for events. The fact that it also boasts a full bar, dance floor, sound system, and an amazing ambiance only furthers its brilliance as a birthday party venue.

7. Include rustic flair with a glamping tent

Who says a tent can’t make a glamorous party decoration? You don’t even have to be a fan of camping to appreciate this boho-style bell tent venue in Ringgold, GA. It’s a fun blend of rustic charm exterior with a sophisticated glam interior, making it perfect for birthday decoration ideas for adults. 

8. Show off a boho flower curtain 

Hanging flowers can create a stylish and trendy touch for your party décor. Just take a look at how well this romantic renaissance venue in Tacoma, WA flowers to create a unique statement in the room. The blossoms almost look like falling snow! It’s one of the most magical adult birthday party decoration ideas that’s boho, chic, and festive all in one. 

9. Celebrate birthday royalty with a throne 

When it’s your birthday, you’re royalty for the day. So why not emphasize your royal status with a birthday throne? Set up a prop throne at your venue where you can stage photos or unwrap your gifts in style.

If you need inspiration, this Atlanta party venue has plenty of thrones to choose from spread across two levels. In fact, you can host the birthday party here and enjoy the vibe that the 12 thrones affords your gathering.

10. Prepare a rustic table spread 

If you’re planning on hosting a birthday dinner, you’re going to love this pretty decoration idea. Use your table settings and centerpieces to set the stage for a birthday dinner party that reflects your unique sense of style.

The table settings at this boho modern Williamsburg event loft in Brooklyn, NY walk a beautiful line between formal and rustic, helping set the tone for a birthday dinner that’s refined and fun.

11. Bake delicious and adorable desserts 

Cupcakes aren’t just a birthday treat — they’re also an adorable birthday party decoration idea. Use the decorations on your birthday cake to tie your décor together. If you’re not a fan of cake, colorful donuts or cookies could do the same trick!

By using edible objects as a decoration, you can heighten your overall décor and create a more immersive atmosphere at your party. If you need more space to bake your delicious creations, a kitchen rental venue through Peerspace like the one in this custom-designed earthy modern home in Nashville, TN can lend a helping hand. 

12. Let the natural scenery be your decoration 

Sometimes, the best decoration for a birthday party isn’t balloons or streamers. It’s the dazzling sights at your party venue itself. And there’s no better way to appreciate nature than to host your birthday party in the great outdoors.

You can easily book sensational outdoor party venues on Peerspace that let nature be your canvas. For instance, this gorgeous garden house for social and creative events in Washington, D.C. provides a lush and inviting atmosphere that’s perfect for celebrating spring or fall birthdays with a little help from Mother Nature. 

13. Play water games

Water features are another dazzling way to set the scene for a special day. But how do you use water as a decoration at a birthday party? Simple, host at an awesome pool party venue via Peerspace, like this bohemian Los Angeles oasis on Peerspace.

Just imagine sipping your favorite drink from those cozy lounge chairs and watching the sun shimmer off the cool blue water. When your venue is beautiful enough as is, you don’t need any extra decorations to make the space special for your big day. 

14. Use chic dried pampas grass to make a statement

If you want birthday decoration ideas for adults that add a sophisticated touch without much effort on your part, be sure to hang some oversized dried pampas grass. As an example of the look we’re going for, check out this intimate beauty escape and party studio in Denver, CO. It uses dried pampas grass in muted tones to add earthy tones and texture to otherwise bare walls. It’s an effective way to elevate your birthday party decor unexpectedly.
