Imagine two office spaces, both 250 square metres, both in a good location. The first asks €150 per square metre per year. The second is listed at €250 per square metre but comes fully furnished, with fast internet, Wi-Fi, meeting rooms and reception services included. On paper, the first option looks like the obvious choice. In practice, it may turn out to be the more expensive one. Understanding why requires looking beyond the rent line and examining what you actually need to spend before your team can sit down and start working.
The rent tells you what you pay for the space. Not what the space will cost you.
Every occupancy decision involves at least two financial layers. The first is the rent, which is visible, easy to compare and typically the number that dominates the initial conversation. The second layer consists of everything else: the investments and recurring costs that make a space usable for your specific organisation. This second layer varies enormously depending on the type of office you choose and the digital delivery level of the building.
To understand the full picture, two concepts are worth defining clearly.
CAPEX (Capital Expenditures) refers to one-off investments in assets with a longer useful life. For office tenants, this typically includes data cabling and network infrastructure, Wi-Fi access points and switching equipment, patch panels and server rooms, technical modifications to existing installations, and elements of the physical fit-out. These costs are incurred upfront, often before a single employee has moved in, and they affect a company's liquidity in a direct and immediate way.
OPEX (Operating Expenditures) covers the recurring costs of running your space: monthly internet subscriptions, managed IT services, software licences, maintenance contracts, cleaning, and service charges. These costs continue throughout the lease term and should be factored into any honest comparison between office options. If you want a deeper look at what these service charges typically include, the guide on service charges for commercial property on RE-SEARCH is a useful reference point.
Neither category alone gives you the full picture. What matters is the Total Cost of Occupancy (TCO): the combined sum of rent, CAPEX, OPEX and any exit costs over the full lease period.
Conventional office space: lower rent, but what do you still need to arrange?
Conventional office space is typically delivered at an agreed specification level. What that specification includes varies considerably from building to building and from deal to deal. Some landlords deliver a space with modern CAT6A cabling, active network points and glasvezel access already in place. Others hand over a shell with little more than electricity, heating and basic finishes.
A tenant taking on a conventional office may need to invest in some or all of the following before the space is usable:
- Data cabling and network infrastructure, including patch panels and cabinets
- Wi-Fi access points and network switching equipment
- Activation or upgrade of fibre-optic connections
- A dedicated and secure IT environment, including firewall and segmentation
- Furniture, meeting room facilities and workstation equipment
- Any technical modifications required by the specific business operation
These are not marginal costs. For a 250 square metre office, a full data infrastructure fit-out, including cabling, active equipment and internet provisioning, can run well into five figures. When you add furniture, meeting room technology and any structural modifications, the initial investment can substantially outweigh the apparent saving on rent per square metre.
There is a second consideration that tenants often underestimate: what happens to those investments at the end of the lease? Cabling installed by a tenant may need to be removed when the lease ends, depending on the terms of the agreement. Assets that cannot be moved are effectively left behind. In some cases, tenants may even face a contractual obligation to restore the space to its original condition. These end-of-lease costs can be significant and should be included in any TCO calculation from the outset. The complete guide to renting office space covers this and other practical aspects of the leasing process in more detail.
Business centres and full-service offices: less CAPEX, but more OPEX?
Business centres and full-service office concepts operate on a different financial logic. The provider has already made many of the investments that a conventional tenant would have to make independently. Workstations, internet, Wi-Fi, meeting rooms, reception and cleaning are typically bundled into a single usage fee or service package.
For the tenant, this means lower initial CAPEX. There is no need to procure cabling, negotiate an internet contract from scratch or furnish an empty floor. The organisation can often be operational within days of signing.
The trade-off is a higher recurring cost. That bundled fee reflects the landlord's investment and ongoing operational expenses. Whether this is financially advantageous depends on how long you plan to stay, how many of those services you would actually use, and whether the included infrastructure meets your specific requirements.
That last point deserves emphasis. Included internet is not the same as suitable internet. An organisation with demanding cybersecurity requirements, its own network segmentation, redundancy needs or specific application dependencies may find that the standard connectivity in a business centre does not meet its operational standards. In that case, additional investment is still required, narrowing the CAPEX advantage that attracted the tenant in the first place. For organisations weighing this trade-off carefully, the article on flexible office versus fixed lease offers a structured framework.
Turn-key office space: furnished does not mean IT-ready
Turn-key office space sits between the two models above. The space is delivered in a largely ready-to-use condition, typically including furniture, finishes and some degree of technical infrastructure. But turn-key is not a standardised concept, and what it includes varies significantly between providers and properties.
A turn-key office may be fully furnished while internet contracts, network management, telephony, access control and other IT services still need to be arranged separately. Before signing any turn-key agreement, tenants should clarify the following:
- What digital infrastructure is physically present in the space?
- Which IT services are included and which need to be contracted independently?
- Who owns the equipment that is already installed?
- Which costs are one-off and which recur monthly?
- What is the tenant's obligation regarding that equipment at the end of the lease?
Turn-key means the space is ready. It does not mean your organisation is ready to operate. That distinction can represent a gap of tens of thousands of euros in unplanned investment.
A comparative overview: three office types, three financial profiles
| Factor | Conventional office | Business centre / full-service | Turn-key office |
|---|---|---|---|
| Initial investment | Potentially significant | Generally limited | Depends on what is included |
| Rent per m² | Often lower | Often bundled in total package | Varies by contract |
| Data cabling | Existing or tenant's responsibility | Often included | Confirm what is present |
| Wi-Fi and network | Usually tenant's responsibility | Basic provision usually included | Verify what is included |
| Internet subscription | Usually separate | Often included | Usually separate |
| IT management | Usually tenant's responsibility | Sometimes partially included | Usually tenant's responsibility |
| Flexibility | Depends on lease terms | Often more flexible contracts | Depends on lease terms |
| CAPEX for tenant | Potentially high | Generally low | Depends on delivery level |
| OPEX | Varies by own provisions | Often higher integrated fee | Depends on services required |
To make this concrete, consider a fictional but realistic comparison. Two organisations each take 250 square metres for five years. Organisation A signs for a conventional office at €150 per square metre per year (€37,500 annually) and invests €40,000 upfront in data infrastructure, Wi-Fi, an internet contract and basic furniture. Organisation B signs for a full-service business centre at €250 per square metre per year (€62,500 annually) with no material upfront costs.
Over five years, Organisation A pays €187,500 in rent plus €40,000 in upfront CAPEX, plus estimated OPEX for managed IT services of around €10,000 over the period, and potentially €5,000 to €10,000 in restoration costs at lease end. Total: approximately €242,500 to €247,500. Organisation B pays €312,500 in rent with minimal additional costs. In this scenario, Organisation A remains cheaper overall. But reduce the lease to two or three years, increase the CAPEX requirement or add redundancy infrastructure, and the picture shifts substantially. The point is not which model wins. The point is that the comparison requires a full TCO calculation, not just a rent comparison.
The digital delivery level: the factor most tenants never check
When evaluating a commercial property, most tenants scrutinise the floor plan, the energy label, the parking ratio and the lease terms. Few systematically assess the digital delivery level before signing. Yet that level determines how much needs to be invested before the space is genuinely operational.
A building may already have modern fibre connections, structured CAT6A cabling, a properly equipped patch room and the infrastructure groundwork for smart building technology. If those provisions exist and match your requirements, your CAPEX is substantially reduced. If they do not, you will discover the gap after you have committed to the lease.
This is precisely the problem that IT-Label addresses. IT-Label is developing an independent standard that makes the digital delivery level of commercial real estate transparent and comparable, in the same way that an energy label communicates a building's sustainability credentials. RE-SEARCH has become an official knowledge partner of IT-Label, a collaboration described in more detail in the article on making the invisible visible in commercial real estate.
An IT-Label does not guarantee that every tenant can start without additional investment. What it provides is a verified starting point: a clear picture of what digital infrastructure is present, so that the gap between what exists and what your organisation needs can be assessed before you sign, not after. If you want to explore what the label means in practice, the plain-language explanation of the IT-Label is a good place to start.
What this means for landlords and investors
The implications of digital infrastructure quality are not limited to tenants. Landlords and investors face a related strategic question: is it more effective to let each successive tenant fund their own digital fit-out, or to invest once in building-wide base infrastructure that reduces that burden?
A building with modern fibre access, structured cabling, proper patch rooms and data conduits in place is easier to let to a wider range of tenants, including technology companies, financial services firms and other digitally intensive organisations. It also reduces the time between lease signing and occupancy, which benefits both parties.
The distinction worth maintaining here is between building-bound IT investments (infrastructure that remains part of the property regardless of which tenant occupies the space) and tenant-bound IT investments (provisions specific to one organisation's operation). The former may improve a building's marketability and lettability over time. Whether it translates directly into a higher asset value or rent level depends on market conditions, tenant demand and the quality of the infrastructure itself.
For landlords exploring office space in Amsterdam or considering stock in logistics-heavy regions such as office space in Rotterdam, the question of digital infrastructure quality is increasingly relevant to both letting speed and tenant retention.
Stop comparing rents. Start calculating total costs.
Choosing an office is not a question of finding the lowest rent per square metre. It is a question of understanding what your organisation will actually spend to occupy, equip and operate that space over the full lease period. A conventional office at €150 per square metre can easily cost more than a full-service option at €250 once CAPEX, OPEX and exit costs are properly accounted for. Or it may not, depending on your IT requirements, your lease length and what infrastructure is already in place.
The only way to know is to ask the right questions before you sign. What is the digital delivery level of this building? What needs to be invested before we can operate? Who owns the infrastructure that is already there? What are our obligations at the end of the lease?
The cheapest office on paper is not always the most cost-effective office in practice. Stop searching. Start investigating.
