This design aims to seamlessly integrate diverse cultures and share life services. It establishes an extended family function system centered on the residential community, addressing the need for life convenience near home, fostering cultural exchange, and creating a community rich in belonging, warmth, and emotion through everyday activities such as community events, social welfare, and neighborhood interactions. This approach explores an ideal community lifestyle.

01 | Community and City

The project is situated in the core area of Zhuhai City’s Tangjiawan back ring, deeply infused with Tangjiawan culture. To the north lie Zhongshan Park and Nanhai Bay, with nearly a century of history. To the east is the Shenzhen-Pearl River Cooperation Demonstration Zone, destined to become a high-end industrial cluster on the west bank of the Pearl River Estuary. While surrounding simple villages are gradually disappearing, the site still retains a gate tower from early 20th-century Zhongshan Park and several mature banyan trees integrated within the plot. Memories intertwine and spaces fragment. The area’s characteristics and planning goals define the complexity and integration of local blocks within this urban renewal project.

02 | Pedestrian Streets with Warm Communities

Our approach emphasizes creating an experiential, welcoming, and diverse neighborhood journey, a guiding principle in addressing complex design challenges.

Boundary

The neighborhood center is located along the main axis of the planned area, linking the city to the south, nature to the north, and residential communities to the east and west. It aims to embrace the region’s complexity, bridging urban lifestyles, natural surroundings, and cultural imprints. The design invites people into the space, allowing natural and public areas to foster new possibilities for the community and its lifestyle. Therefore, the building boundaries are designed to blend and interconnect with the surroundings seamlessly.

▲ Integration of Wenbao Park’s greenery into the neighborhood

We designed three distinct pedestrian paths with porous, open permeability to enrich the walking experience. Additionally, the greenery from Wenbao Park to the north is maximally integrated into the block. To provide more public strolling space, part of the residential landscape area has been allocated to the neighborhood center.

Scene Recreation and Social Interaction at the Gatehouse

Real places are not merely found between buildings, but in experiences worth remembering.

— Curtis J. Scharfenaker

The nearly century-old Zhongshan Park Gate Tower in Wenbao Park has witnessed the area’s renewal and development. This place holds great significance for local residents, serving not only as a historical record but also as an emotional memory and spiritual anchor. Preserving the spirit of this site is a natural desire aligned with current trends. We envision the ancient trees and buildings, together with the new neighborhood center, creating a warm and memorable space that fosters interaction between residents and their history.

The design responds in layers, creating a multidimensional dialogue space with the heritage building. The cultural heritage plaza on the ground floor becomes a key node on the pedestrian route, forming an enclosed, centripetal space between old and new structures. This area serves as a social gathering spot that encourages neighborhood communication, connects people to the site, and strengthens community bonds.

The terraced design allows visitors to view the gatehouse from elevated vantage points while offering places to rest and reflect within the fusion of old and new.

Neighborhood Life Spaces

The clubhouse exhibition hall, landscape coffee shop, fresh food supermarket, and other interactive functions are located on the building’s ground floor. These spaces are open to the public in courtyard-style blocks, providing a vibrant interface. Less frequently used community functions are vertically stacked on the second-floor public terrace, creating ample grey space for social interaction across the first and second floors, forming an open, three-dimensional community. The private clubhouse occupies the top floor, offering views of the northern natural landscape.

03 | Design and Construction Modulus: Means and Ends

The project presents site-specific architecture through simple spatial and experiential forms. We recognize that simpler design demands more research and coordination. The building employs a unified basic module across structure, space, and curtain wall, conveying a precise and orderly design from inside out while controlling building height.

The main facade features imitation stone aluminum panels combined with glass blocks, creating a striking contrast between weight and lightness, solidity and transparency.

Material choices include light gray aluminum panels and highly reflective glass. The top block uses imitation stone aluminum panels to minimize joints compared to natural stone. The third and fourth floors feature low-key dark patterned glazed glass, producing varying degrees of semi-transparency and transparency. The ceiling finishes incorporate warm, low-saturation tones, delivering a simple yet distinctive aesthetic.

Conclusion

This project explores the future lifestyle of communities. As a key node within the regional fabric, the neighborhood center aims to introduce an open, green local character that enhances quality of life internally and externally. It also embodies an architectural dialogue between old and new urban elements. Successful design involves not only passionate creativity but also rational decision-making within existing conditions. Collaborating closely with property owners and multidisciplinary teams, we employ rigorous, scientific methods to control every aspect, collectively crafting meaningful community life experiences.
