Home tour: How Chang Architects’ majestic Moongate House in Bukit Timah blends Chinese heritage with modular craft

The owner is a first-generation immigrant from northern China who has lived in Singapore for decades. “He sought a home that balanced privacy and professional grandeur, accommodating both his family and frequent diplomatic events, as he often hosts gatherings related to his business and role as an appointed consul,” explains Chang.

For research purposes, Chang visited Shandong province. He was struck by its traditional stacked stone buildings and stone bridges, whose arched undersides form a perfect orb with their reflection—akin to the moon gate portals in historical Chinese gardens. Inspired, the architect conceptualised a concrete-block module with glass and window infills, and stacked these like Lego pieces.

They form privacy and sun-shading screens when pieced into large panels. Chang also shaped moongate-like apertures with them. “These panels form the facade and structure of the moon gate—a feature that draws inspiration from the owner’s roots and offers a symbolic connection to the landscape. The forest behind the house is framed with this moon gate, establishing a tranquil relationship between the home and forest,” he elaborates.

The Moongate House sits on a 32,658 sq ft plot in Bukit Timah. To avoid a gargantuan building, Chang sited the car park and an entertainment zone with massage rooms, a gym and a karaoke room in the basement. Skylights provide natural illumination so these spaces do not feel excessively subterranean.

“Despite the relatively large site, the floor area is kept compact, creating an expansive feel by ensuring each space is framed by views of either the forest or the garden,” says the architect. A notable aspect of the site was the secondary forest that borders one side; the surrounding tall trees and wild undergrowth paint a soothing, bucolic picture.

“The owner bought the property because of this forest,” Chang shares. Thus, it only made sense for the Moongate House to open up to this vista. He divided the architecture into two long parallel volumes, connected by an impressive water feature that terraces up both ends.

“From the outset, the owner had preferred a linear organisation of the spaces. At first, this did not seem the most feasible, given the diamond-shaped profile of the plot. However, by positioning the more public areas at the front and the private spaces towards the back, where the width is greater, the design aligns well with the plot,” Chang explains.

The front volume is one storey and the rear has two storeys, thus they sit relatively low on the land rather than overwhelm it. The rear block contains the living and dining areas on the ground level, and bedrooms on the second storey. A farm-to-table garden caps the roof.

To bring cohesion between architecture and interior, Chang collaborated with interior design studio Designworx Interior Consultant, helmed by his former NUS classmates Eleanor Kor and Terri Tan. “Yong Ter approached us because he needed someone who could understand his architectural vision and interpret the client’s needs with sensitivity,” shares Kor.

The studio worked on key interiors across both levels, including the entrance foyer, banquet and private dining rooms, kitchen, master suite, prayer room, daughter’s suite and conference room. The result balances architectural grandeur with understated yet detailed interior tableaux that speak of quiet elegance.

“The house’s layout takes advantage of the site’s natural features. The main living spaces are oriented east–west, which minimises exposure to the sun while maximising cross ventilation by capturing the monsoon winds. The precast sun-shading panels, inspired by Shandong’s traditional architectural forms, provide both functional shading and aesthetic appeal,” explains Chang.

The front block houses a home office, library and meeting room, as the owner often holds discussions at home. There is also a larger double-volume dining room for banquets related to his diplomatic work. Chang opened up one side for a layered vista to the central pool, rear garden, and forest beyond.

Stone is the key material, used for the facade, ground-floor finishes, and wet areas. “In contrast, wood is employed in the more intimate spaces, such as the bedrooms, library, home office and meeting rooms,” says Chang.

The entry’s burgundy marble, chosen by the wife, gives it a nostalgic appeal. “She calls it ‘Takashimaya stone’. This is the exact stone cladding used on the Ngee Ann City building at Orchard Road where Takashimaya [Shopping Centre] is located. It was not easy to find because it’s not very popular,” he elaborates.

Aside from the prefabricated modular blocks, Chang also collaborated with local and foreign artisans to create translucent folding screens adorned with ornamental motifs and laser-printed on laminated glass, as well as woven fabric screens in the living room and sculptural washbasins made by glass artisans.

The project presented many challenges to the architect, who is satisfied with how it ultimately turned out. He comments: “Moongate House harmonises modern design with cultural heritage, creating a sanctuary that offers both privacy and grandeur. It is a celebration of culture, context and craftsmanship.”
