Treehouse Hotel Manchester Expansion Adds Rooftop and Suites

Fourteen floors above Manchester's city centre, string lanterns sway gently between exposed beams as the skyline stretches out beyond floor to ceiling glass, the city's towers catching the last light of evening. It is here, on the rooftop of a hotel that opened barely eighteen months ago, that a new chapter is quietly taking shape. Treehouse Hotel Manchester Expansion plans have now been unveiled, adding rooftop dining, new suites and a wide set of wellness facilities to a property that has grown quickly since its debut.

Treehouse Hotel Manchester is expanding its offer significantly since opening in March 2025, according to details shared by the hotel, with more information available through the property's official website. The scale of the addition, spanning multiple floors and several distinct venues, signals a hotel moving well beyond its original footprint in a relatively short span of time.

Sister Moon Anchors the New Rooftop

The headline addition is Sister Moon, a new rooftop restaurant spread across the 14th and 15th floors, created by chef Sam Grainger alongside hospitality collaborators Luke Cowdrey and Justin Crawford. Grainger, known for his work at Belzan in Liverpool, has built a menu that combines British ingredients with Southeast Asian influences and open fire cooking, using the panoramic Manchester skyline as a constant backdrop to the dining room rather than a peripheral detail.

Joining Sister Moon on the rooftop are two further venues designed to extend the evening in different directions. The Nest, a cocktail bar built around an agave led menu, offers a more energetic counterpoint to the restaurant, while The Hideout provides an intimate, speakeasy style lounge complete with its own outdoor terrace, giving guests a quieter alternative within the same rooftop footprint.

Nine New Suites Across Two Floors

Beyond the rooftop, the expansion adds nine new premium suites across the 11th and 12th floors, rounding out the hotel's accommodation offering with options built specifically for families, groups and extended stays. Presidential suites and interconnecting room configurations sit within this new tier, reflecting a broader shift toward flexible, longer stay formats that many urban hotels have been developing in response to changing travel patterns.

Wellness and Recreation Join the Offer

The expansion also reaches beyond dining and accommodation into recreation and wellness. Two covered padel courts have been added via The Pollen Club next door to the hotel, giving guests access to one of the fastest growing racquet sports without leaving the immediate property. A wood fired outdoor sauna from The Good Sauna Co. rounds out the new wellness offering, adding a slower, more restorative counterpoint to the energy of the rooftop venues above.

These additions sit alongside the hotel's existing offer, which already includes Pip, the all day lounge and bar led by chef Mary-Ellen McTague, a 43 seat cinema equipped with 4K projection and Dolby Atmos sound, and flexible event spaces capable of hosting up to 400 guests.

A Hotel Repositioning Itself as a Destination

Raul Leal, chief executive officer of Starwood Hotels, framed the expansion as a shift in what the property represents within Manchester's hospitality landscape. "With this expansion, Treehouse becomes a true urban resort, bringing together incredible dining and rooftop experiences with exceptional fitness and wellness, a state-of-the-art cinema, and flexible spaces to meet and gather," Leal said. The comment matters because it positions the hotel less as a place guests simply sleep and more as a self contained destination built to hold an entire evening, or an entire event, within its own walls.

A Continued Role in Manchester's Events Calendar

The hotel's growing venue offering has already found traction beyond individual guest stays. Treehouse Hotel Manchester will host micebook's Northern Edition for the third consecutive year in 2027, having previously welcomed the event in both 2025 and 2026, a repeat booking that reflects the confidence event organizers have placed in the property's expanding facilities.

Recognition of that kind, built through repeat trust rather than a single award, echoes a pattern seen elsewhere in the hospitality industry, where consistency over multiple years often carries more weight than any single accolade, as seen recently in InterContinental David Tel Aviv's fifth consecutive conference hotel award. For Treehouse Hotel Manchester, the coming months will test whether its rapid expansion can sustain the same kind of steady, returning trust, not just from guests checking in for a night, but from a city increasingly looking to its rooftop as a place worth returning to.
