"Most of our work as a company currently is hotel-based, so we have a strong understanding of what makes these kinds of spaces special," co-founder Andy Goodwin told Dezeen.
"A lot of the other commercial clients we work with are aiming to achieve a very layered, somewhat residential feel to their spaces so there is a lot of overlap," he continued.
"We utilised many of the same suppliers we use within members clubs, hotels and restaurant projects."
After coming through the ground floor entrance of The Gessner, residents arrive at a lobby that's richly furnished with sofas, patterned armchairs and a mix of vivid artworks curated by art consultant Kate Anniss.
During the day this area serves as a communal workspace, while in the evenings it can be used as an oversized living room where residents can convene and chat.
Nearby, there's a cafe with wood-lined walls, tan leather seating and a terrazzo service counter inlaid with orange aggregate.
Furnishings and fabrics found on The Gessner's ground floor are also incorporated throughout the apartments, which are available furnished or unfurnished, as well as in a pair of guest suites located on the building's 13th floor.
These can be reserved by residents who have friends and family coming to visit, or by other travellers hoping to stay in the area.
The 13th floor plays host to a number of other communal facilities, which were designed to encourage socialising among residents.
This includes a large dining room and kitchen with wooden cabinetry and a greenery-filled gantry that stores pots and pans.
There's also a lounge and a spacious outdoor terrace complete with sun loungers, beach-style umbrellas and a BBQ station set beneath a shady pergola, where residents can while away the warmer summer months.
"One of the key things with both hotels and apartment buildings is having some synergy between the public and private spaces, which was successful at The Gessner as they feel like a continuation of each other," Goodwin said.
Fettle was established in 2013 by Andy Goodwin and Tom Parker.
The Gessner isn't the only project to come from the studio this year. Last month, the duo finished work on The Malin, a homely co-working space in New York with loft-style interiors.
