Mosh Interior founder Shermaine Maena Ong translates the unseen “code” of clients’ lifestyles into spaces focused on a sense of belonging
It is hardly startling that Mosh Interior’s designer Shermaine Maena Ong’s affable and empathic spirit would inevitably filter into the spaces she crafts. Imbued with a deep sense of storytelling and a human subtext, her creations highlight a client’s childhood memories, heritage, or professional drive, transcending mere “showroom” aesthetics to create unique abodes that honour the homeowner’s lifestyle and backstory.

A graduate of the Nanyang Academy of Fine Arts (NAFA), Ong has worked with high-end luxury retail, corporate offices and bespoke F&B brands; each sector elevated her technical vocabulary and distinct spatial skills. These days, she helms Singapore-based boutique firm Mosh Interior, which takes on high-end A&A (Addition & Alteration) and full-scale reconstruction assignments. Ong is assisted by her “left-hand man” Darrion Loo and “right-hand lady” Yann Guo in the design team, project director Michael Lee, along with Josh Lim and Gabriel Ong in the project team.

“Sustainability in this trade is entirely dependent on human capital,” she says. “Finding the right talent is a perpetual exercise in trial and error, requiring me to evolve as much as a business leader as a designer.”
Soul sister
Ong views design as a form of “behavioural alchemy”, in which the nuances of homeowners’ living habits should be evident in the architecture. This results in residences with true hearts that feel authentic. “Every individual is a unique composition of habits and desires; when designing for a family, these disparate ‘ethos’ must be merged into a harmonious, singular narrative,” she explains. “Much like an original painting, no two spaces can—or should—ever be identical.”

Deciphering this “puzzle” of human behaviour is a boundless source of inspiration to her. “I look for the subtext in conversations [with clients],” Ong reveals. “Often, a joke or a casual anecdote reveals more about their aesthetic soul than a Pinterest board ever could. There is profound satisfaction in reconfiguring a floor plan in a way the client never imagined possible—unlocking a lifestyle they didn’t realise they could have.” And to her, the meaning of “luxury” is the “intelligent and creative manipulation of materials”. “If a rare material is used without a dialogue with the surrounding space, its value is lost,” she declares.
Tatler Homes profiles some of Ong’s most memorable projects, each balancing technical rigor with a sense of empathy to reveal spaces that not only look good, but facilitate a better way of being.

An effortlessly airy vibe pervades this refurbished semi-terraced house located on the fringes of Orchard Road in Singapore. Its mix of restful outdoor spaces, and sprinkling of Australian and European-inspired design elements cleverly recall the owners’ previous residence Down Under and carve out a cosy personal sanctuary in the heart of the Republic.
A pale colour scheme enhances the brightness of the interiors, while the doors and windows were also extended to let in more light. The owners’ beloved collection of art jazzes up the sedate scheme with dashes of colour. A spacious garden at the front of the house, coupled with a pool and a barbecue and breakfast zone in the backyard, are perfect for leisurely afternoons and a throwback to the owners’ Australian roots.
For all seasons
Three generations of a family live in this elegant 2,885 sq ft apartment, which is characterised by pale timber and creamy tones in the common areas, given a lift by metal trimwork and marble fittings. Tailored to meet the lifestyle and individual needs of each occupant, this sleek, modern abode boasts exquisite detailing and practical inclusions in equal measure. Furniture from Italian brands Poliform and Poltrona Frau add a dose of artisanal craftsmanship and classic design.

Compared to the home’s light and breezy common areas, the bedrooms feature enveloping dark wood fittings and an earthier palette. Soft backlighting adds a gentle glow and breaks up the uniformity of the gloomy scheme, creating the ideal zone for relaxation and recuperation.

The Breeze House pays homage to the outdoors with its emphasis on natural light, biophilic elements, and considered cross-ventilation. Putting nature front and centre in its design concept, the five-bedroom terrace house boasts a capacious light well that aids in natural illumination. Concrete breeze blocks on the facade ensure privacy while enabling circulation, while cascading plants add greenery and life.
A floating staircase with suspended wooden treads adds a feeling of lightness and encapsulates the home’s spirit of openness, while the split-level construction of the house itself invites light and breezes in. Overall, it is an excellent example of architecture co-existing harmoniously with the natural world, and of a well-crafted home blurring the boundary between the indoors and outdoors.
