Rising along Irwell Bank Road in central Singapore, Irwell Hill Residences introduces a fresh architectural identity to the city’s skyline.
The project, designed by MVRDV in collaboration with ADDP Architects, transforms the logic of modular construction into a dynamic façade — one that feels alive, textured, and responsive to the landscape.
Two 36-storey towers redefine what PPVC (Prefabricated Prefinished Volumetric Construction) can be, shifting from pure efficiency to a crafted visual language.
Developed by City Developments Limited (CDL), the project marks MVRDV’s first residential high-rise built in Singapore’s urban core.
Modularity as Architectural Expression
At the heart of Irwell Hill Residences is the PPVC system, a construction technique that relies on off-site manufacturing of entire room modules — complete with finishes, services, and façade components.
This method reduces construction time, noise, on-site disruption, and waste, perfectly aligned with the ambitions of Singapore’s Green Plan 2030.
Yet PPVC is often associated with rigid repetition.
MVRDV challenges this assumption by treating each module as a pixel, articulating the façade through subtle variations in depth and frame extension.
The result is a coherent yet richly animated exterior — a façade that shifts with the light, reveals pockets of greenery, and avoids the monotony typically associated with modular towers.
The deep gold and rich brown tones of the metal cladding, visible in the press images, form a pattern inspired by climbing plants, reinforcing the integration between architecture and Singapore’s verdant landscape.
Sky Gardens and Communal Landscapes
The pixelated language expands and loosens at key moments.
On level 24, the grid opens dramatically to reveal a four-storey sky garden, a communal space suspended between the towers where plants, air, and views come together.
At the towers’ peaks, Irwell Sky introduces landscaped roof terraces for residents — spaces that extend the building’s vegetation upward, turning the skyline itself into a vertical garden.
Here, the pixel grid stretches further, creating deeper frames and more open voids that highlight the presence of greenery.
These communal landscapes act as architectural clearings, moments where the building breathes outward and reveals its social and environmental ambitions.
Sustainability as Long-Term Urban Value
Beyond its reduced construction footprint, Irwell Hill Residences presents sustainability as a question of durability, identity, and urban presence.
MVRDV emphasises that a building is environmentally successful only if it enriches its surroundings and remains valuable for decades to come.
By transforming modularity into a distinctive architectural expression, Irwell Hill transcends the neutrality of typical PPVC buildings, giving Singapore a residential landmark with strong cultural and visual resonance.
A Vertical Landscape for Contemporary Singapore
With Irwell Hill Residences, MVRDV demonstrates how prefabrication can evolve into an expressive urban language — one that is efficient, sustainable, and deeply tied to place.
The towers stand as living pixels, a modular composition animated by balconies, gardens, and calibrated depth, rising above one of Asia’s most innovative cities.
In Singapore’s dense vertical landscape, Irwell Hill offers a blueprint for the future: architecture that emerges from industrial precision, yet grows with the organic rhythm of nature.
