Making Your Building Affordably IT Future-Proof

A landlord typically invests without hesitation in painting, climate installations, floor finishing, lighting, entrances, sustainability and charging stations. These are the visible parts of a building, and they are the parts on which a property is traditionally judged. Yet the attention of tenants is increasingly shifting to something you cannot see.

Because as soon as a prospective tenant asks which internet providers are available, whether fiber comes in, whether redundant connections are possible, what CAT cabling is in place and where the patch cabinet is located, things sometimes go remarkably quiet. The information is often not there, or nobody knows where to find it.

The logical question then is: why wait until a tenant raises these questions during negotiations? This article shows how you can make a building digitally better step by step, without it starting with an expensive IT installation or a major renovation.

What does IT future-proof actually mean?

IT future-proof real estate does not mean the landlord has to build the complete business network for every future tenant. It means the building offers a solid digital foundation, a base on which tenants can easily connect and build further.

The landlord does not need to arrange the tenant's laptop. But the building does need to make the digital highway possible. That distinction is decisive for what does and does not belong to the landlord's responsibility. This dividing line keeps returning in articles about who invests in what.

Digital quality, like other building qualities, can be expressed in levels. The IT-Label classification runs from IT5 SHELL, a building without digital infrastructure, to IT1+ PREMIUM, a building delivered AI-ready. The goal is not to lift every property to the highest level, but to make visible where it stands.

Start with knowing what you have

The first and cheapest step is stocktaking. Before you buy anything, establish what is already present. You do not need to invest right away. Knowing what you have first prevents you from spending money in the wrong place.

During such a pre-inspection, check at least the following:

• does fiber come in, and where exactly?
• which providers can actually deliver?
• what cabling is in place and in what condition?
• where are the patch cabinets and technical rooms located?
• are up-to-date as-built drawings available?
• which equipment is owned by the landlord, and what belongs to tenants or providers?

An IT-Label pre-inspection, also known as the digital MOT of your building, maps these points in a structured way. This tells you where you stand before you make a single decision about investments.

Make providers and fiber transparent

A relatively simple improvement is making it clear which telecom providers can actually serve the building. Not just the statement that fiber is present, but specifically which providers deliver, what capacity is available, how long the lead time is and whether a second connection is possible. You can read more background on this in our article on fiber in buildings.

With this information you answer prospective tenants' questions immediately, instead of a negotiation stalling because nobody knows the answer. Also check whether fiber ends only in the central technical room or can easily be extended to the individual units.

Smart preparation often consists of empty conduits, cable trays, available shaft space, pull cords and easily accessible technical rooms. Preparing is almost always much cheaper than breaking things open afterward.

Tomorrow's cheapest cable is sometimes the empty conduit you lay today.

Account for redundancy and the technical room

Redundancy does not always have to be fully implemented immediately. However, you can ensure that a second independent connection remains technically possible, for example by reserving a second entry point, keeping alternative cable routes free and installing conduits. You do not need to deliver redundancy right away, but prevent a future tenant from discovering that it is structurally impossible. We explain why one connection is sometimes not enough in network redundancy.

One of the cheapest improvements is simply creating order in the patch and server room. Check for old equipment, unused cables, unknown modems, abandoned switches and loose power supplies. Label cables and equipment, remove only what is demonstrably no longer in use and document the situation with photos.

A tidy server room is not just more pleasant to manage. It makes faults, changes and future expansions considerably easier. At the same time, make sure not everyone has access: lockable doors, access control, key registration and locked racks often increase digital resilience without a major investment.

Cabling, power and cooling

Have it determined which cabling is present, whether that is CAT5e, CAT6, CAT6A or fiber. Not every building needs to be completely recabled right away; existing infrastructure is sometimes still perfectly usable. But what is unknown also cannot be reliably offered to a tenant.

During any renovation, install empty infrastructure right away. An empty conduit or cable tray costs relatively little during renovation, while opening up walls, ceilings or floors later can turn out to be expensive. Also think about the physical support of digital equipment.

Therefore check technical rooms for sufficient outlets, separate circuits, space for a UPS, ventilation, cooling and for water pipes above equipment. Small improvements prevent big problems here. Wi-Fi coverage is also often tenant-specific: you do not need to install a complete network yourself, but make sure access points can be placed, that cabling to ceilings is possible and that PoE is supported.

Document and establish responsibilities

Create a simple digital file with floor plans, cable routes, technical rooms, connection points, providers, fiber, the backbone, photos and responsibilities. Good documentation is relatively cheap, but has great value in leasing, faults, renovations, sales and Digital Due Diligence. A building where nobody knows how the digital infrastructure runs is difficult to call future-proof.

Also set out in a digital demarcation list who is responsible for what. This prevents discussions during faults and handover and ties in with what we wrote about responsibilities in the ROZ lease agreement.

Example of a demarcation list

Use vacancy as an opportunity. When a unit becomes vacant, inspect the cabling, remove old tenant equipment, label connections and, where needed, add a few strategic cables or conduits. The best moment to improve digital infrastructure is often when the tenant is not there.

From cost item to leasing argument

You can also use improvements to digital infrastructure commercially. Instead of only stating that 500 square meters of office space is available, you can indicate that multiple providers are available, that fiber is present, that the building is prepared for redundancy and that the digital delivery level is transparent. This turns digital infrastructure from a technical cost item into a leasing and value argument.

It helps to organize improvements by scale. Most steps require little budget:

• Quick wins: stocktaking, documentation, labeling, provider checks, clearing the technical room, improving access control and drawing up a demarcation list.
• Affordable preparation: conduits, cable trays, an extra fiber route, an upgrade of the central backbone, better patch cabinets and additional power supply.
• Larger investments, only when needed: complete recabling, a new fiber backbone, redundant provider infrastructure or a full enterprise network environment.

Not every building needs to be IT1+ PREMIUM tomorrow. But every building can take a step forward today, and that is exactly what this approach is about.

Take the first step today

Making a building IT future-proof does not have to start with a server cabinet full of new equipment. It starts with three things: knowing what you have, clearing away what is no longer needed and preparing for what is coming. The smartest digital investment is therefore not always the most expensive one; sometimes it is a second conduit, a locked technical room and a floor plan that finally shows where the cables run.

An IT-Label pre-inspection helps you make the existing situation visible, identify quick wins, separate necessary investments from nice-to-haves, set priorities and demonstrably improve your digital delivery level. If you want to know exactly how this methodology works, you can read about it at how the IT-Label works.
