Sulzer Redevelopment
The Sulzer Redevelopment represents a critical intervention at the intersection of industrial archaeology and modern urban density. The site, a former machinery manufacturing hub, sits on a brownfield parcel that has long been severed from the surrounding neighborhood by vacant lots and degraded infrastructure. The redevelopment seeks to remedy this severance by stitching the site back into the local fabric through a high-density, mixed-use program that honors the site’s productionist past while creating a liveable, permeable urban quarter.
Heritage and Adaptive Reuse
The primary architectural challenge is the tension between demolition and preservation. Rather than treating the existing industrial structures as obstacles, the master plan adopts a strategy of volumetric preservation. The primary machinery hall is retained as a civic anchor—a large-span volume that can accommodate flexible workshop spaces, exhibition areas, and a maker-hub. This preserves the industrial scale of the site and provides a distinctive public amenity that anchors the redevelopment’s identity.
New construction is designed as a contrast rather than a mimicry. Timber-frame residential blocks are positioned on the periphery of the machinery hall, using a repetitive, modular language that references the repetition of factory machinery without overtly copying its form. This distinction between the historic fabric and the new additions allows the heritage structures to stand out as landmarks rather than being subsumed into a monolithic new development.
Mixed-Use Zoning and Economic Activation
The plan avoids the trap of creating a mono-functional bedroom community. Economic activation is achieved through three layers of use:
- The Maker-Hub: Ground-floor spaces within the machinery hall are zoned for light manufacture, artisanal production, and creative workshops. This maintains a productionist link to the site's history while fostering a modern creator economy.
- Street-Level Retail: A continuous retail plinth along the eastern frontage activates the public realm and provides a pedestrian-friendly interface with the adjacent neighborhood.
- Upper-Level Housing: The residential blocks provide high-quality apartment stock, with a mix of unit sizes to cater to a diverse demographic, from single professionals to families.
By integrating production, commerce, and residence, the redevelopment generates a 24-hour urban environment that supports local employment and reduces the need for extensive commuting.
Public Realm and Connectivity
A major planning objective is to repair the site's isolation. The master plan introduces a pedestrianized public realm that extends the neighborhood's existing street grid directly into the site. A central pedestrian corridor cuts through the redevelopment, linking the eastern retail front to the west side of the machinery hall, which serves as the neighborhood's new civic square.
Connectivity is further strengthened by a dedicated transit link on the southern edge, ensuring that the high-density housing remains accessible without creating excessive vehicular pressure on the surrounding streets. The pedestrian-first approach is reinforced by removing internal parking from the public realm and concentrating vehicular storage in a screened, underground facility.
Sustainability and Circularity
Environmental goals are met through a combination of circularity and high-performance standards. The plan utilizes reclaimed brick salvaged from the site’s demolished warehouses for the new masonry facades, reducing embodied carbon and reinforcing the materiality of the district. The timber construction of the residential blocks further lowers carbon compared to traditional concrete frames.
The site is also designed with a proactive water management strategy:
- Rainwater harvesting from the machinery hall roof feeds the public realm’s irrigation and toilet flushing.
- Permeable paving and bioswales along the pedestrian corridors manage runoff and reduce the urban heat island effect.
- Passive House standards are targeted for the residential blocks to minimize operational energy demand.
The Sulzer Redevelopment succeeds by treating the site’s industrial heritage as a civic asset rather than a liability, creating a dense, permeable neighborhood that feels both grounded in the past and prepared for the future.
