Here we transformed a couple of Cotswold stone barns into the ultimate 21st party venue. One barn was dressed out for the sit-down dinner with speeches and the other was turned into a cocktail bar with pop-up nightclub. 


Here are just some of the reasons why we are the first choice for so many 21st birthday parties.

21st Birthday Party in the modest setting of Downton Abbey

When you get the call to organise the 21st of the real heir to “Downton Abbey” you have to go for it… and go for it they did! We pulled out all the stops providing everything to make the party rock until 4am…….. Carson would not have approved!

How do we do it?

How do we make your party planning process smooth and enjoyable?

Our 5 step process.
  1. We talk on the phone to get an idea of what you want to do. It’s important to us that we only do the best events. So we make sure that we are in sync with you before we go any further.
  2. Meeting at your venue. Almost all of our clients events are at home on their lawn in a marquee. It’s what we specialise in. We steer clear of Hotels and Function venues as we can be way more creative and impress guests if we can come away from the conference and wedding function rooms.
  3. We listen to your plans and go through all your ideas. We spend time getting to know what you like and how you want your guests to feel. The Party Planning starts now. We will be throwing ideas at you, bringing in thoughts about logistics and physical limitations to create your bespoke perfect party.
  4. You will be sent a professional Bespoke Party Planning Quote. This is fully itemised with pictures of every item you will need. Everything is individually priced so you can see exactly where your budget is going. We ensure that your quote is complete. Everything you need. Nothing extra needed, Nothing hidden, No sting in the tail.
  5. Once you book you can leave it all to us. We plan your party using our own equipment, specialist trusted, used plenty of times before suppliers and our great crew who will build, run and clear away your party with no fuss, no hassle and plenty of smiles.

Themed 21st parties are a speciality. This 60’s extravaganza really went for it.

Occasionally we are asked to run with an idea and make the night the best it can possibly be. With this brief we stretched ourselves to pull off an amazing themed party. With a champagne drinks reception, sit down meal, dancing until 7am and yurt accommodation for those who maxed out too early, this was one night to remember. Throw in a spectacular venue and a warm marquee and you have a serious night of excess on your hands. Get in touch for a free quote

We serve free drinks all night.⁠
Don't worry though we have subtle ways of ensuring that guests will last till midnight rather than peaking by 9 pm. ⁠
We find it is better to stay in control of alcohol consumption with expert bar staff tailoring drinks to the guests 🍹🍸🍺⁠
