It’s our birthday, and we’re inviting you to celebrate with us in iconic Killing Kittens style. We are not only bringing you a birthday ball - we’re bringing you a birthday ball, wrapped up in a Mansion party, in a brand new, breathtaking country venue. 

This is our biggest mansion to party to date, with the added bonus of exclusive access to bedroom wings. We have a limited number of luxury bedrooms and decadent suites available to book, each with all the amenities and comfort you would expect from a Killing Kittens hotel stay. 

A Victorian mansion surrounded by landscaped gardens and woodland is the setting for this opulent and extravagant birthday party. Take a stroll through the grounds on arrival, revelling in the atmosphere of indulgence and excitement for the night to come. Hidden away from the hustle and bustle of busy city life, this grade II listed country mansion is the perfect place to slip off your inhibitions and discover ways to live deliciously.  

Indulge in a sensual journey, beginning with the most potent aphrodisiacs and ice cold fizz, before being entertained and delighted by an array of exquisite erotic performances. The evening reaches fever pitch at 10.30pm, when our playspaces open for your exploration and enjoyment… There’s never any pressure to play at a Killing Kittens party, so allow the evening to unfold in whatever way you wish.

With everything you could possibly desire for a night of pleasure and indulgence, make sure you don’t miss the opportunity to celebrate our birthday with us at the most gorgeous Country Mansion party yet. 

What To Wear:

There’s a strict dress code at Country Mansion. In keeping with the luxurious venue, it’s black-tie which means red carpet glamour: beautiful dresses, smart suits or tuxedo and of course the compulsory Killing Kittens mask to add to the mystique...at least until 11pm.

We do not allow casual streetwear, jeans, sportswear, loungewear, t-shirts, leggings, sneakers, boat shoes etc. A Killing Kittens event is a place to dress to impress. We can, and will, refuse entry with no refund if you do not adhere to the dress code.

Check out these articles from GQ and Vogue for a little extra guidance on what black-tie entails.


Our luxurious location is a mere hour’s drive from London, allowing for an easy escape from the city.

Car parking is strictly limited. People who have booked a room will have one car parking space allocated to them. Additional car parking tickets will need to be pre-booked, and are extremely limited.

For those that are not staying on site, we will be running shuttles to and from specified local hotels. If you would like a space please let us know by pre-booking this option.

Local hotels will be recommended upon ticket purchase. 

What Will Happen...?

Doors open at 8pm with strictly no entry after 10pm. Mansion is a fluid evening of exploration, there’s no set agenda once you’ve arrived. Masks come off at 10.30pm, when you’re free to begin exploring the playspaces (and each other). And remember, what happens at KK stays at KK...It’s back to reality at 2am, when the event ends.


Only people who book rooms will be able to access these areas of the mansion, meaning that the party can continue long after everyone else has had to go home… Make sure you book with accommodation to make the very most of this indulgent Mansion party. Guests not staying at the hotel will not be allowed into these areas under any circumstances.

Check in: You will be able to check in to your room from 3pm on the day of the event. Please note, event set up will be taking place during the day, but this will not affect the bedroom wings. Get settled in and explore the grounds before getting ready for the event in the evening. The bar will be open at 7.30pm exclusively to guests staying on site. 

Check out: Breakfast will be provided. Check out is by 11am. 

Who Can Attend?

We do things a little differently at Killing Kittens, actively empowering women, trans and non-binary people through our ticketing process and party rules. Only Kittens’ Association Members can buy tickets to our parties, and only Party Approved Guests can be invited to join them. Your application for Membership or Party Approval will need to be successful before you can buy tickets or be invited to attend a party. If you are not already a Member or Approved, please start the process - the sooner the better, as our events have a habit of selling out.

Single Kittens’ Association Members are welcome to join us at this event. There will be no single Guest tickets available for purchase. 

All Booked?

We’ll email you out the rules, regulations and the full venue address four days before the party to enable you to make travel arrangements.

Ten days before the event you can head to the KK Chat app and jump into the pre-party group. Only available to people that have tickets, this is where you can connect with other party goers, ask any questions you might have, or arrange a pre-party drink. It’s the perfect place to start building up anticipation for the night...

Your Safety Is Our Priority:

Safety, security and discretion are key to a KK event. We want you to feel secure in the knowledge that we have a network of measures in place to ensure that you can relax and enjoy your evening with us.

Entry is only possible with your personalised e-ticket. Think of it as your passport - if there isn't a photographic match, there will be no entry.

Entry to all KK events is subject to signing an NDA, showing a photo ID, and is always at the management’s discretion.
