Sustainability and good vibes are the signature moves at Treehouse London, one of the few Green Key eco-certified hotels in the English capital. Two minutes from Regent Street, this woodland-inspired luxury roost is kitted out with upcycled furnishings and no surface is left without a succulent. Besides the extensive use of reclaimed wood and woven textiles, all spaces are abundant in natural light – another component of biophilic design. Generously-sized rooms have panoramic windows and glass-walled bathrooms while cocktails at The Nest are shaken to a backdrop of the London Eye and The Shard.
Inside Treehouse London: The Eco-Certified Hotel Bringing Whimsy to Mayfair
The Treehouse guest experience unites the three pillars of a London getaway: cracking food, epic cityscapes, and quirky activities. Simply wandering around this boutique hotel brings a childlike glee; the 15th-floor lounge is decked out with makeshift arrows and bird houses that may remind you of the dens you built as a kid. Mason jars filled with rogue buttons and jigsaw pieces feel like you could be at a family home.

Whimsical rooms at Treehouse Hotel London

Checking into my Lookout King Room felt partly like stumbling into a bird’s nest, partly like hopping aboard a vintage train. Cuckoo clocks and animal-shaped scatter cushions added character while a Paddington Bear plush greeted me from the train carriage-style luggage rack. I spent most of my downtime at the hotel cocooned in the window nook, flicking through the books stacked on the nightstand and watching the comings and goings from BBC Broadcasting House. Additional tomes are found downstairs in the lobby library, contributed by previous guests and the “Book Fairies” of London – this Mayfair hotel is all about the simple pleasures.
Despite being in the heart of one of Europe’s busiest cities, the room was soundless thanks to non-disruptive air-con and this corner of Mayfair being peaceful enough at night to leave the windows ajar. Staying at Treehouse during the height of British summer when daylight hours clock in at 18 per day, I appreciated the blackout blinds when the sun rose at 4 a.m. and loved the lazy sunsets over All Souls Church.
Mayfair’s coolest rooftop bar – The Nest at Treehouse London

Claiming the entire 16th floor, The Nest at Treehouse London is an indoor-outdoor rooftop bar with knockout views and a slew of wholesome activities. Both terraces gaze across Mayfair and Westminster with Canary Wharf looming on the horizon. The larger of the two has a Laurent Perrier Champagne and oyster pop-up over the summer. Come winter, the interior is a charming spot to take shelter, with squashy couches and Persian rugs under a canopy of lanterns oozing coziness.
“Midday Tipples” give patrons consent to day drink while “Night Caps” are playful takes on the classics. The bartenders are more than happy to rustle up an off-menu cocktail and there’s a decent choice of alcohol-free quenchers. The Nest hosts a regular line-up of events ranging from pet-portrait workshops to fire-breathing spectacles and weekend DJ sessions. It’s worth giving the bar’s Instagram a follow ahead of arrival to keep tabs on what’s coming up. As The Nest is a popular watering hole for Londoners, it’s also wise to reserve a table in advance during peak hours.

One floor down, Madera serves larger plates for lunch and dinner. I started each morning of my stay at this enclosed restaurant, lingering over carne asado and eggs Benedict as the city woke up below. The Mexican-inspired à la carte features the likes of ceviche, grilled octopus, and tacos with a commendable selection of vegan and gluten-free plates. Madera was one step ahead of the “spicy marg” trend, with farm-to-glass cocktails orbiting around tequila and mezcal mixes garnished with a touch of picante. Besides a ban on single-use plastics and self-service water stations on every floor, the hotel uses the Foodprint model to monitor food consumption and limit waste.
Sustainable lodging in the heart of London’s West End

Treehouse London is very much a lifestyle hotel with the best of the city’s culture and entertainment on the doorstep. Regent Street’s boutiques are a stone’s throw from the hotel, as is an endless choice of restaurants. I had little reason to take public transport during my stay, enjoying early-morning window shopping before idling down to catch the Summer Exhibition at the Royal Academy and wandering over to Covent Garden at dusk.
Identifiable by a gigantic robin perched adobe the atrium, Treehouse London deviates from the traditional Mayfair hotel. But bearing in mind that almost 50 percent of London is classified as green space (and, in fact, the world’s first National Park City), this eco-luxe hotel with its cheeky character and creature comforts captures the modern soul of the capital.
