The Return of Floor Space – Why Urban Logistics Is Changing Intralogistics

For a long time, space in logistics was primarily a cost issue; in cities, it is becoming a strategic resource. Micro-fulfillment, vertical warehouses, and automated micro-hubs demonstrate how this is transforming the architecture of intralogistics and what modern urban logistics truly entails. A package ordered today is expected to reach the customer tomorrow, today, or—ideally—within a few hours. What appears to be a matter of speed from the consumer’s perspective is, from a logistics standpoint, primarily a matter of location.

After all, speed cannot be automated at will.

A highly automated distribution center can store, pick, and sort goods with impressive efficiency. However, if it is located 100 or 150 kilometers away from the actual center of demand, the “last-mile” problem begins after picking. Vehicles must drive into cities, use public roads, and spend time in urban traffic. At the same time, the very space needed to bring warehouses closer to customers is becoming scarce. Housing, commercial space, transportation, energy supply, green spaces, and logistics all compete for the same space in growing cities. The traditional logistics solution—larger warehouses in the most cost-effective locations—is thus reaching its limits. The consequence is remarkable:

The warehouse is returning to the city. But it’s not returning as a traditional warehouse.

It’s coming back as a vertical, automated, modular, and data-driven facility.

The traditional distribution model has one obvious advantage: centralization creates economies of scale. Large warehouses have high capacities, specialized automation, and efficient material flows. Inventory can be consolidated, processes standardized, and personnel and technology utilized more effectively. But centralization has a downside.

The farther a warehouse is from the customer, the longer the downstream transport route becomes. For traditional B2B supply chains, this may be acceptable. For time-sensitive B2C orders, groceries, or everyday essentials, however, geographical proximity becomes significantly more important. This shifts the focus of optimization. The question is no longer just:

How cost-effectively can a single order be processed in the warehouse?

But rather:

How can the entire journey from inventory to the customer be optimized?

This is a fundamental shift in perspective. Intralogistics and transport logistics are becoming increasingly difficult to distinguish from one another. The warehouse’s location directly influences the costs and efficiency of the last mile. A slightly more expensive warehouse location can therefore make economic sense if it reduces transportation distances, delivery times, or vehicle movements significantly. The cost per square meter becomes part of a much larger calculation.

A particularly clear example of this is micro-fulfillment centers (MFC). Their basic principle is simple: A limited product range is stored as close as possible to the center of demand and automatically prepared for delivery. The MFC does not have to take on the role of a traditional central warehouse. On the contrary: Its strength lies precisely in its specialization.

Items with high demand and high turnover can be stocked decentralized. The central warehouse continues to supply the entire network and carries the broad product range. The MFC acts as a local accelerator. This is technically interesting because high throughput must be achieved in a small space.

Compact shuttle systems, for example, can store and retrieve containers or boxes in densely packed racking systems.
Autonomous mobile robots (AMRs) can transport goods or shelves to workstations. Automated picking solutions reduce manual movement. A Warehouse Management System (WMS) manages inventory and orders, while a Warehouse Execution System (WES) coordinates operational processes and resources in an increasingly dynamic manner. The real challenge here is not to cram as much technology as possible into a small building.

The challenge is to generate as much logistical performance as possible per square meter.

This is an important distinction. A highly automated system can achieve enormous storage density and still be inefficient if access times, stock transfers, or interfaces are poorly designed. Therefore, the interplay between storage density, throughput, availability, and energy consumption is crucial.

When floor space is limited, one solution is obvious: build upward. Vertical warehouses are certainly not a new concept; high-bay warehouses have been part of the intralogistics toolkit for decades. What is new, however, is that the principle is becoming increasingly relevant in areas where land is particularly expensive and scarce—that is, in or near urban areas.

This creates an interesting tension between storage density and access performance.

Storing goods as compactly as possible reduces the amount of space required. At the same time, the system must be able to retrieve the needed items quickly and reliably. Furthermore, the taller the facility, the more significant structural, static, fire safety, and energy-related considerations become.

Automation can mitigate these conflicting goals.

Modern stacker cranes, shuttle systems, and other automated warehouse technologies can utilize great heights while simultaneously achieving defined throughput rates. Dynamic storage strategies ensure that frequently needed items are positioned as efficiently as possible. This reflects a fundamental shift in intralogistics:

Optimization no longer takes place solely horizontally.

It is becoming three-dimensional and increasingly algorithm-driven.

Automation in the past was often designed for large, clearly defined material flows. Conveyor systems linked stationary processes, stacker cranes served fixed aisles, and sorting systems processed large volumes of standardized shipments. Urban logistics, however, presents different challenges: The product range can be more diverse. Demand fluctuates more significantly. Spaces are smaller. Expansions must be possible. And the building’s infrastructure often cannot be easily adapted to a new logistics system.

As a result, modular automation concepts are gaining importance.

Mobile robotics is a good example of this. AMRs can dynamically adjust their routes and, unlike permanently installed conveyor systems, can be deployed differently when warehouse layouts change. This makes them particularly attractive for smaller and evolving locations. The need for flexibility is also increasing for stationary systems. An MFC that currently processes 10,000 order lines should not necessarily have to be completely rebuilt if the order volume or product range changes.

Scalability thus becomes a core technical requirement. Consequently, the decisive metric is not always “maximum throughput.” Sometimes the more important question is:

How quickly can the system respond to changing requirements?

The more warehouse structures become decentralized, the more important digital connectivity becomes. Even in a single large distribution center, control can already be complex. In a network consisting of a central warehouse, regional warehouses, micro-fulfillment centers, and micro-depots, it becomes an even more demanding task.

• Where is each item located?
• Which order is being fulfilled from which location?
• When is it worthwhile to transfer stock?
• Which items should be stocked locally?

And how does the answer change when demand shifts within a matter of hours?

A modern WMS maps inventory and logistics processes. The WES can optimize operational execution and coordinate resources such as robots, conveyor systems, or workstations. In addition, data-driven methods and AI-supported forecasts can help better predict demand trends and distribute inventory more strategically. This creates an interesting reversal:

The less physical space available, the more important the quality of digital control becomes.

Because in a small warehouse, every mistake is costly. Incorrectly positioned inventory, an unnecessary stock transfer, or a poorly prioritized order can immediately cost capacity and throughput. Data thus becomes a kind of virtual extension of the physical space.

For decades, “bigger” was considered synonymous with “more efficient” in many sectors. This makes sense. Large facilities offer economies of scale. Automation can be implemented cost-effectively, processes can be consolidated, and fixed costs are spread across larger volumes. However, this logic does not automatically account for the costs of geographical distance.

A small warehouse in the heart of an urban area may be significantly more expensive per square meter than a logistics center on a greenfield site. It can still make economic sense, however, if it reduces transportation distances by thousands or millions of kilometers within a network.

This gives the small location a new role: It doesn’t have to do everything—it must take on the right task at the right place.

This could involve the provision of high-turnover items, supplying a network of retail locations, temporary storage for the last mile, processing returns, or consolidating various goods flows for a specific neighborhood. The traditional warehouse thus becomes a building block of a larger system.

This trend is even more evident in urban logistics hubs.
A micro-hub can simultaneously serve as a warehouse, a transshipment point, and a staging area for the last mile. Goods are consolidated and sorted there before being redistributed using appropriate vehicles. In densely populated areas, for example, smaller electric vehicles or cargo bikes can be used. What matters most here is not so much the individual vehicle as the question of how the flow of goods is structured prior to the last mile. This also changes the requirements for intralogistics.

Goods may need to be transshipped multiple times. Time windows are becoming tighter. Shipments must be sorted by routes, areas, or delivery priorities. At the same time, only a limited amount of space is available. An urban logistics facility must therefore do more than just store goods—it must sort, buffer, consolidate, and schedule. The line between warehousing and transportation is blurring.

This development has a dimension that goes beyond technology and economic efficiency. Logistics spaces were traditionally kept as invisible as possible. Large warehouses were built wherever commercial space was available, while the city was supposed to notice as little of it as possible. This approach is becoming increasingly unsustainable.

With the growth of online retail, same-day deliveries, and increasing delivery frequency, logistics is becoming a visible part of urban life:

• Delivery vehicles require road space.
• Package stations require locations.
• Micro-depots require space.
• Stores are becoming pickup points.

The city itself is thus becoming part of the logistics infrastructure; and this raises political questions:

• How much space should a city allocate for logistics?
• How can logistics, housing, and commercial use be combined?
• Can parking garages, former retail spaces, or other buildings be used for logistics—either temporarily or permanently?
• And how can we prevent additional logistics space from reducing delivery times while simultaneously degrading quality of life?

One answer could lie in multifunctional spaces.

A building does not necessarily have to be used exclusively as a warehouse. Spaces could serve different functions depending on the time of day or their use. This also makes the integration of logistics into existing buildings more appealing. As a result, urban planning is increasingly becoming logistics planning as well.

Amid all the enthusiasm for urban logistics, however, it’s worth taking a critical look. More warehouses in the city do not automatically mean less environmental impact. An additional building requires energy, resources, and infrastructure. Multiple small locations can result in higher operating costs than a single central location. Decentralized inventory management may also increase stock levels under certain circumstances. Therefore, the overall balance must be considered.

A meaningful comparison takes into account, for example:

• Land use per logistics service
• Energy consumption per order
• Transport kilometers
• Vehicle utilization
• Inventory and capital tied up
• Throughput and service level
• Automation and labor costs
• Delivery time
• Returns and wasted trips
• System scalability

Only then can we determine whether decentralization actually yields a benefit. This is also relevant to the sustainability debate. The shortest physical route is not automatically the most environmentally friendly. What matters is the interplay of warehousing, energy, transportation, and utilization.

This fundamentally changes the significance of space. A square meter in an industrial park and a square meter in an inner-city neighborhood do not serve the same logistical function.

The value of a space is increasingly determined by its position within the network.

A small location, for example, can be particularly valuable if it can serve a densely populated area within a short time window. Its importance cannot then be assessed solely based on cost per square meter. This leads to a new dimension of key performance indicators. In addition to warehousing costs, storage density, and throughput, companies must increasingly ask:

What impact does this location have on the entire network?

• How many kilometers does it save?
• What delivery times does it enable?
• Which inventory levels does it make necessary or redundant?
• How does it change vehicle movements?
• How well can it respond to fluctuations in demand?

Space is thus evolving from a mere production factor into a strategic asset.

What does this mean for the warehouse landscape in the coming years? Probably not the end of large logistics centers; rather, a hybrid network is emerging.

Central distribution centers will continue to efficiently consolidate large product ranges. Regional warehouses will handle the supply of larger areas. Micro-fulfillment centers will bring particularly relevant goods closer to where demand is. Micro-depots will manage the last mile. The individual levels must be digitally interconnected.

An order should not be fulfilled from an urban MFC simply because inventory happens to be available there. The system must be able to determine which location is the optimal source, taking into account inventory, distance, delivery time, capacity, and costs. This is a significantly more complex task than traditional warehouse optimization. Intralogistics is thus shifting from location-based thinking to network-based thinking.

The large logistics warehouse isn’t going to disappear, because its economies of scale are too valuable for that. But it will have company: Smaller, automated, and strategically positioned warehouses will become attractive in locations where proximity to the customer is more valuable than maximum centralization. Vertical systems will make more intensive use of the third dimension.

Mobile robotics will bring flexibility to smaller spaces. WMS and WES will no longer just control individual facilities but will increasingly become part of a networked logistics system. And the city will evolve from being merely a destination in the supply chain to an active component of the infrastructure. The real question for the future is therefore not:

How do we build even larger warehouses?

It is:

How do we distribute logistics capacity so that every square meter, every robot, and every kilometer traveled generates as much value as possible for the overall system?

This is more than a technical challenge. It is a question of urban development, sustainability, and economic resilience. Because when space becomes scarce, logistics can no longer be solved simply through growth. It must become more precise. Perhaps this is precisely the reason behind the surprising renaissance of small warehouses. They do not represent a return to the past, but rather a new type of intralogistics: smaller in footprint, denser in technology, and greater in their significance for the overall network.

Paradoxically, the future of logistics could thus be determined less by how much space a company owns—and more by where that space is located, how intelligently it is used, and how well it interacts with the other locations in the network.

This perspective is crucial. After all, the scarce resource of the urban future is not just warehouse capacity. It is the space between the distribution center, transportation infrastructure, the company, and the customer. The return to physical space therefore does not mean that logistics will once again take up more room. It means that the right square meter in the right location is once again becoming a central component of logistics strategy. And this is precisely where one of the most exciting developments in intralogistics lies:

The future of the warehouse may no longer be determined solely within its four walls, but rather by its position within the urban fabric.
