Trevor Tower is a comprehensive architectural repositioning project that transforms an existing high-rise apartment building into a contemporary luxury residential destination in Gading Serpong, Indonesia. Commissioned to redesign both the building envelope and interior public spaces, INSADA approached the project as a complete reinvention rather than a cosmetic renovation, redefining the building's identity while working within the limitations of its existing structure.
Originally developed as a high-density residential tower with compact one-, two-, and three-bedroom units, the building no longer aligned with evolving market expectations. The design strategy centered on elevating the development into an upscale residential address by reorganizing the residential typologies into generous two-, three-, and four-bedroom apartments, culminating in exclusive five-bedroom penthouses on the uppermost floors.
This transformation required extensive spatial reconfiguration without altering the primary structural framework. Multiple apartment units were consolidated into larger residences, demanding careful coordination of structure, building services, and circulation. Mechanical systems were comprehensively upgraded, including the introduction of VRV air-conditioning systems and the reorganization of plumbing infrastructure to maximize ceiling heights and improve overall spatial quality.
At ground level, the most significant intervention involved converting the existing parking podium into a welcoming residential arrival experience. Large portions of the podium were reprogrammed to accommodate a new entrance lobby and resident amenities, establishing a stronger relationship between the building and the public realm.
The exterior architecture introduces a refined material composition that reinforces the tower's new identity. Italian travertine anchors the podium with warmth and permanence, while high-performance aluminum window systems improve both daylight performance and façade expression. Dark charcoal aluminum composite panels are contrasted with metallic copper accents to create a layered architectural composition that emphasizes the building's vertical proportions.
Inside, the arrival sequence is defined by a dramatic double-height lobby created by strategically removing sections of the existing floor slab. Natural daylight floods the space through expansive glazing, enhancing the sense of openness. Book-matched marble flooring, sculptural travertine feature walls, and custom-designed lighting elements establish an atmosphere of understated luxury. Every material was selected to balance timelessness with contemporary refinement while reinforcing the building's repositioned market identity.
Beyond the reception area, communal amenities extend the residential experience. A library and co-working lounge provide flexible spaces for work and relaxation through a combination of warm timber finishes, integrated shelving, acoustic ceiling systems, and transparent partitions that maintain visual connectivity.
The wellness facilities expand the podium through a dedicated extension housing a fitness center, yoga studio, and spa jacuzzi. Here, filtered natural light passes through timber louver systems, creating dynamic patterns across textured stone surfaces and fostering a calm, resort-inspired environment within an urban residential setting.
The architectural transformation concludes at the tower crown, where a newly designed rooftop pavilion establishes a distinctive skyline presence. A dark-framed roof structure complemented by warm timber detailing creates a recognizable silhouette while visually unifying the entire composition from podium to roof.
Rather than replacing the existing building, Trevor Tower demonstrates how thoughtful architectural intervention can extend the life of aging residential developments through strategic planning, spatial reconfiguration, and material refinement. The project illustrates the potential of adaptive transformation to create a contemporary luxury living environment while preserving the value embedded within the original structure.
