Our 7 innovative outdoor birthday party ideas 

There’s no denying the fact that an outdoor kitchen can act as an entertainment hub
 especially if there is food and drink on offer. The kitchen has always become a focal point for any party, acting as a magnet for your guests. And, an outdoor setting tends to create more of a casual and laid-back atmosphere, allowing everyone to relax and enjoy the day. The only thing that matters is the weather!

Below, we’ve got 7 of our favourite outdoor birthday party ideas that you can take inspiration from and utilise all year round. Without further ado, let’s light the candles, blow up the balloons, and explore them in a bit more detail
 

1. Host a pizza party 

If you do have an outdoor kitchen, then it’s the perfect opportunity to host your own outdoor pizza party. A classic birthday treat, pizzas are extremely versatile and popular among guests. You can even turn it into a fun activity, giving friends and family the opportunity to make their own dough and add their favourite toppings. And, while they’re known for baking pizzas, an outdoor oven can cook a variety of delicious dishes if pizzas aren’t your style. 

This crowd-pleaser cuisine transcends across all age groups, making it ideal for a party with guests of all ages from kids to grandparents. If you’re feeling unconvinced, have a read of our blog post: Are Pizza Ovens Worth It? 

2. Create a cosy seating area 

An outdoor party naturally creates a social and interactive atmosphere, allowing your guests to chat, chill, and eat. However, you don’t want your guests to stand up for the whole day, which is why creating a cosy seating area is essential. Not only is it practical, but it will help to create an inviting atmosphere for all those invited. 

If you’ve already got outdoor seating, whether that’s a plump sofa or practical dining table and chairs, opt for soft furnishings such as cushions, blankets, and rugs for pure comfort. We also recommend adding fairy lights, lanterns, and other warm lighting options for an inviting glow. 

3. Don’t forget to provide some shade

If you’re lucky enough that the sun is shining, investing in some form of shade is wise. One of the most obvious benefits is that you will be protecting your guests from harsh UV rays, preventing sunburn and heatstroke. It will also allow your guests to enjoy the party more as they are kept cool and comfortable on a hot day. 

However, shade is practical in all types of weather, come rain or shine. And, luckily for you, here at Open Space Concepts, we’ve got plenty of practical shade options from modern pergolas to retractable awnings. Each of our awnings is fully automated meaning that you can extend and retract as you wish, suiting the type of weather you experience on the day of your party. 

4. Fire up the barbecue

An outdoor party is the ultimate excuse for a sizzling barbecue. The ultimate crowd pleaser, this party idea will keep everyone happy and means that you’ve got an excuse to utilise your outdoor kitchen. Cook up classic party foods such as burgers, hot dogs, and kebabs, and keep your guests well-fed throughout the day. 

If you’re hosting a party for a larger number of people, then a barbecue is the perfect catering solution. The smell of grilling will add to the experience of being outside and celebrating, and you can also experiment with different rubs, sauces, and marinades if you fancy yourself as a culinary expert.

5. Invest in an outdoor cinema 

Take your party to the next level by investing in an outdoor cinema. This can be easily achieved by picking a good-quality projector and creating a cosy seating area for guests to snuggle up and enjoy the film. While the initial investment might seem like a lot, you can consider it an investment in creating a truly memorable and unique party experience. 

You could also theme your party around the idea of going to the cinema – watching a film will take up a large chunk of your time, and you can supply guests with popcorn, candy floss, and other cinema related snacks. You could even get your guests to dress up as the characters in the film that you choose to watch. 

6. Opt for a classic picnic 

Another one of our outdoor birthday party ideas is to keep it classic by having a picnic. A great British picnic is a traditional activity and helps to create a chilled-out and relaxed atmosphere, perfect if you aren’t a fan of hosting full-on, upbeat parties. There’s no need for fancy decorations or strict schedules, you can enjoy the simple freedom of munching away on classic picnic dishes. It’s also a great way to relax under the sunshine and catch up with family and friends. 

If you are feeling fancy and want to utilise your outdoor kitchen, then you can create your favourite cocktails or mocktails, the perfect picnic companion. Having an outdoor bar is perfect for this activity, and we’ve got 6 ideas to get you started

7. Provide plenty of games 

No party is complete without fun activities and games, and there are plenty you can play outdoors. Games are a great source of entertainment and will prevent your guests from getting bored. Plus, it can add some structure to the day. If your party consists of a range of ages, there are games that cater to everyone. 

If your lawn is big enough, you could play sports such as badminton, croquet, or volleyball. Or, if you want to keep the party less active things like giant Jenga, frisbee, or giant Connect Four are great alternatives. Ensure that you have the correct equipment before your party starts, and you can even offer a small prize to the winning team.
