Top 10 amazing summer party venues in London

In the UK, summer is a glorious but brief time of year. The moment the sun decides to show itself off, we Brits flock outdoors like it’s our first time seeing it. With long days and (hopefully) sunny skies, summer parties are a rare chance to soak up the good weather and sip on a cold drink and pretend we’re all on holidays in the south of France (even if it’s really just a London rooftop garden).

If you’re in the midst of planning that mid-year event, we’ve collated a list of the top ten amazing summer party venues that are sure to bring the summer vibes and make your event unforgettable.

1. The Barbican

Brutalist-meets-lush at The Barbican: an iconic venue that’s truly special. The Barbican’s conservatory is a dense rainforest in the middle of the city with over 2,000 plant species and even koi ponds that make you feel like you’re on another continent entirely. With plants that climb up all of its rough industrial edges, you can enjoy the melding of two opposites in a biophilic design. The Barbican is the perfect summer party venue for those that want a destination party in the heart of London.

2. Century Club London

Hidden behind a regular old door in Soho, the Century Club London recreates the feeling of an exclusive secret bar. Designed for year-round use, this rooftop bar is enclosed enough to favour winter events but features a large retractable roof for those long summer nights. With stunning views to be seen across the city, comfy lounge seating, and a fully stocked bar, it screams summer party venue with its stylish yet relaxed atmosphere. 

3. The Inner Temple

Tucked away in the heart of London’s legal district, The Inner Temple feels like a secret garden wrapped in centuries of history. Its standout feature? An award-winning garden—one of the largest privately owned green spaces in the city—offering a peaceful, open-air setting that’s perfect for summer parties. Think sweeping lawns, mature trees, and a sense of calm that’s rare in central London.

Inside, the Georgian-style Hall brings classic character with wood-panelled walls and vaulted ceilings, giving you a refined backdrop when the party moves indoors. It’s polished, a little unexpected, and ideal for teams after something more memorable than a standard rooftop.

4. Garden Museum

Tucked away on the banks of The Thames, the Garden Museum blends old and new together in a curated green space. Designed by Dan Pearson, the courtyard garden is more wild beauty than manicured perfection—a striking, natural retreat that’s perfect for unwinding in the summer breeze. The interior of the museum is a sleek and modern design that contrasts with its traditional exterior, high arches, and stained glass feature, making it a great pick for an intimate yet grand-feeling event (something a little different from the usual rooftop summer spot).

5. The Standard

Bold, playful, and full of personality, The Standard is just one of those incredible summer party venues. Set in a Brutalist building opposite King’s Cross station, this hotel leans into its retro roots with eclectic interiors, rooftop views, and a serious sense of fun. The standout? Decimo, the rooftop restaurant and bar with floor-to-ceiling windows and a wraparound terrace, perfect for sundowners with a side of skyline. 

Whether you’re planning a cocktail-fuelled celebration or a rooftop takeover with DJ vibes, The Standard delivers something effortlessly cool with a big splash of colour. Expect bold flavours, creative spaces, and the kind of party people won’t forget by Monday.

6. The Hurlingham Club

Live your Pride and Prejudice dreams in one of the last remaining riverfront 18th-century mansions in South West London. The Hurlingham Club has beautifully manicured 42 acre gardens with grand Georgian architecture all on a riverside location and only 20 minutes outside of central London. If you want to create a summer party like the high society of the past (think champagne and croquet), The Hurlingham Club is your go-to destination that brings all that and a little modern country club chic to the table in a private and picturesque setting. 

7. One Marylebone

Impossibly elegant and steeped in history, One Marylebone brings grandeur to the summer party venues scene. Just moments from Regent’s Park, this former church turned event space is all high ceilings, stained glass, and architectural drama. Outside, the private garden offers a rare slice of greenery in the middle of the city—ideal for drinks, canapés, and golden hour moments.

Inside, the soaring Central Space and atmospheric Soane Hall make for an unforgettable backdrop, whether you’re planning a laid-back summer soirée or something with a little more sparkle. It’s timeless, versatile, and made for summer party events that want to impress.

8. The Brewery

Once an actual functional brewery in the 18th century, The Brewery honours its industrial roots while adding a touch of modern style. Its open-air courtyard space is a showstopper in the summer with exposed brick walls, festoon lighting and plenty of space for your summer party needs. It’s the perfect spot to sit back in the city’s heart, enjoying some craft beers and cocktails. 

9. Dartmouth House

Nothing says a summer party to remember like holding it in a hidden gem venue, and Dartmouth House is exactly that. When you first arrive it might look like someone’s private estate but inside it’s a near-royal level of grandeur with a ridiculously pretty marble-enclosed courtyard. Inside, you can find ornate ceilings, dazzling chandeliers, grand staircases, and more. The stunning marble courtyard is filled with grand stonework and a marble fountain to fawn over while sipping on drinks in the summer sun, making it a perfect formal event space for a summer party worthy of The Royals. 

10. Hotel Cafe Royal

Sitting pretty in Piccadilly, the Hotel Cafe Royal is a luxurious venue perfect for celebrating summer. This five-star hotel retains its grand and historic architecture while its interior is refreshingly modern and clean, perfect for those who want to make their summer party an A-list event. Its rooftop space is the highlight factor to your summer party here, with some of the best hospitality in London and fine dining to match.
