London’s skyline is littered with glass‑topped terraces, yet many remain off the typical tourist radar. The reason? Most of them hide behind unassuming office blocks or residential lifts, and they often require a reservation that isn’t advertised on the main website. During a recent weekend I discovered three such spots that offered a view, a drink, and a sense of discovery that a typical “top‑10 list” can’t match.
The first stop: The Loft at 45 Baker Street
Located on the fifth floor of a converted Victorian townhouse, The Loft opens only on Saturdays after 5 pm. Entry is limited to 30 guests, so you need to book at least 48 hours in advance. The bar serves a signature “Baker Street Fizz” – gin, elderflower, and a splash of prosecco – priced at £9.50. What makes it stand out is the 180‑degree view of Regent’s Park, visible through floor‑to‑ceiling windows that are rarely crowded because the venue is tucked behind a discreet brass door.
Mid‑week escape: Skyward at The Old Bank
On Wednesdays the old banking hall on Cannon Street transforms into a rooftop lounge called Skyward. The venue caps its capacity at 25, meaning you can actually hear the city buzz below. Their cocktail menu rotates weekly; the “Ledger Lemonade” (whiskey, house‑made lemonade, and a dash of bitters) costs £12. A standout feature is the small library of board games tucked under the bar – perfect for a low‑key evening.
Speaking of low‑key evenings, many people who enjoy a quiet drink also like a quick round of online entertainment. For those moments, the site ninewin offers a range of casual games that fit neatly between a cocktail and a conversation, without pulling you away from the rooftop ambience.

Sunday sunset: The Greenhouse at Southbank
Perched above the Southbank Centre, The Greenhouse opens from 4 pm on Sundays and closes precisely at sunset – usually around 8 pm in summer. It’s a hidden gem because the entrance is through a service alley that most tourists never notice. The bar’s “Thames Breeze” cocktail, a blend of gin, cucumber, and mint, is sold for £10. The real draw is the live acoustic set that starts at 6 pm, featuring local folk artists. Seating is limited to 20, so arriving at 4:30 pm guarantees a spot on the terrace.
How to plan a rooftop bar crawl
- Reserve early. Most hidden rooftops only accept bookings through a phone call or a short online form, and they fill up within 24 hours.
- Stagger your timings. Aim for a 90‑minute slot at each venue to avoid rush‑hour crowds and to allow travel between sites.
- Dress smart‑casual. Many of these bars enforce a dress code – no trainers, no baseball caps.
- Check the weather. All three locations have retractable awnings, but a sudden downpour can still dampen the experience.
- Carry cash for tips. While card payments are accepted, staff often appreciate a small cash tip for attentive service.
What the hidden bars lack
The main drawback is accessibility. All three venues are tucked behind private entrances, meaning you’ll need a clear address and sometimes a gate code. If you’re traveling with a large group, the 20‑30 person caps can be a bottleneck. Additionally, the limited opening days – Saturday, Wednesday, and Sunday – mean you can’t rely on them for a full‑weekend itinerary without planning around the schedule.
Wrapping up the perfect weekend
By targeting these three rooftops, you can craft a weekend that moves from the historic charm of Baker Street to the sleek modernity of the Southbank, with a quiet mid‑week interlude at The Old Bank. Each spot offers a distinct view, a signature drink, and a low‑key vibe that feels more like a private club than a public bar. Book early, dress appropriately, and bring a sense of curiosity – the city’s best hidden terraces reward the patient explorer.
