Office rental in Greece 2026
✦ Key Takeaways
- Before starting an office search — whether through listings or through an agent — a company needs a clear picture of its actual requirements.
- The true cost isn't just the rent per sqm. It includes initial fit-out capex, operating costs, service charges and more.
- The legal minimum term for new commercial leases in Greece is three years — everything beyond that is freely negotiated.
- Location affects the team's daily routine, client and partner access, and the company's image.
- Grade A / Grade B and delivery condition (cold shell / warm shell) are different things: the first describes the building, the second the specific space.
- Heads of Terms should settle the key commercial points before the final lease is drafted.
- Technical and legal due diligence belongs after Heads of Terms and before the final signature.
Renting an office in Greece isn't just a matter of price per square metre. For a business, the office shapes daily operations, employee access, the image projected to clients and partners, the cost of setting up, and the room to grow over the coming years.
In practice, most mistakes don't happen because a company picked a "bad" property. They happen because the search started without a clear brief, without a full picture of total cost, and without settling early on what the landlord delivers and what the tenant takes on.
The Athens office market is on an upward path. According to the Bank of Greece, prime office prices in Athens rose by 7.0% in 2025, while office rents across all categories in Athens increased by 5.5%. In a market moving like this, preparation, timing and negotiation matter more than they would in a static one.
This guide is written for companies looking to lease office space in Greece for long-term use — Greek businesses that are growing or relocating, and international companies setting up a presence in Greece. It does not cover temporary solutions, flexible offices or coworking spaces.
Why renting an office is a strategic decision
An office isn't just a room where desks, chairs and computers go. It's the base the company operates from, where clients are received, where the team works together and where the day-to-day culture of the business is built.
That's why the decision shouldn't come down to rent alone. A space may look more expensive at first, but serve the staff better, cause fewer delays, need less work and run more predictably. Equally, a cheaper space can turn out expensive if access is difficult, parking is inadequate, service charges are high or significant fit-out work is needed.
Before you start: what the company needs to define
An effective office search doesn't start from the listings. It starts from a concise statement of requirements — the office brief.
Before the first viewing, it helps to have answers to the following:
- how many people work from the office today, and how many are expected to join over the next 2-3 years
- whether the company operates full-time from the office or on a hybrid model
- how many meeting rooms are needed, and whether the layout calls for private offices, open plan or a combination
- whether there are requirements for a server room, data, IT or special installations
- how many parking spaces are essential
- what the total available budget is — not just the rent
A vague brief leads to wasted time, false comparisons and a weak negotiating position.
How much office space do you actually need
Square metres aren't calculated with a fixed number per employee.
| Company type | What to focus on |
|---|---|
| Tech company / startup | open plan, collaboration areas, phone booths, flexibility to grow |
| Consultancy / law firm | private offices, meeting rooms, reception, confidentiality |
| Shipping company | building image, access, parking, meeting rooms |
| Corporate headquarters | Grade A space, ESG, security, shared building services |
| Sales team | access, parking, fast movement to clients |
Location: access, people, clients and corporate image
A company may find a better rent in one area, but lose out on commute times, parking or client access.
| Area | When it makes sense |
|---|---|
| Central Athens | when metro access, a central presence and proximity to services matter |
| Kifisias / Marousi / Chalandri | corporate offices, larger buildings, parking and a corporate environment |
| Syngrou Avenue | connection between the centre, the southern suburbs and visibility on a main axis |
| Piraeus | shipping and services around the port |
| Southern suburbs | the coastal front, the Ellinikon development, south Athens |
| Mesogeion / Attiki Odos | practical access, connection to the main road network |
In Athens, parking and access are not details: spaces per employee, visitor parking, metro access, the building's operating hours, accessibility. If every meeting starts with the question "where do I park?", that's part of the cost of the office — not a footnote.
Grade A and Grade B offices: what they mean in practice
A Grade A building typically offers better technical infrastructure, modern mechanical and electrical systems, quality common areas, better energy performance, security and a more professional image. A Grade B building can be a perfectly good fit for many businesses, especially if it sits in the right location and doesn't require excessive works.
The critical question isn't "is it Grade A?" but rather: does it serve the way the company operates, does the technical infrastructure stand up to the intended use, does it allow the fit-out the tenant needs, and will it remain functional in the years ahead?
💡 Tip: A Grade A office isn't simply more impressive. It usually delivers better day-to-day operation, fewer technical surprises and a more reliable image for a company that wants a stable presence — which often offsets the higher initial rent over a three-year term.
ESG and energy performance: when they influence the decision
For larger organisations and multinationals, sustainability (ESG) criteria may be part of internal policies or of the office selection process itself. Energy performance and building quality affect energy consumption, employee comfort, natural light and the ability to measure and control costs. Not every company needs to lease a certified building — but every company needs to understand what it is leasing. A space with poor energy performance can create operating problems that aren't visible on the first viewing.
Cold shell, warm shell or ready-to-use space
| Delivery condition | What it means in practice |
|---|---|
| Cold shell | no finished infrastructure — exposed walls, bare floor, no working HVAC |
| Warm shell | core building infrastructure such as floors, ceilings, lighting, heating/cooling and basic M&E installations, without the tenant's final fit-out |
| Ready / plug-and-play | faster installation, lower initial investment |
Before making an offer, it must be clear exactly what is being delivered: floor, ceiling, lighting, heating/cooling, electrical, data, partitions, furniture. If this isn't settled early, comparing two spaces has no real meaning.
Office fit-out: cost, time and responsibilities
Fit-out can include partitions, meeting rooms, networks, lighting, furniture, signage and adjustments to heating and cooling systems. That's why it shouldn't be treated as a detail to sort out after the deal — it's a core element of both cost and timeline.
In many leases, part of the negotiation is whether the landlord will grant a rent-free period or contribute to the fit-out cost.
💡 Tip: These details should be settled at the Heads of Terms stage. If they're left for the final lease, they often create friction, delays and tension right before signing.
Rent, service charges and the true monthly cost
Comparing two offices on rent per sqm alone is incomplete. The true monthly cost is shaped by more elements:
| Cost | What to check |
|---|---|
| Rent | per sqm, term, indexation, commencement date |
| On top of the rent | digital transaction duty of 3.6% or VAT |
| Service charges | what they include, how they're billed, cost history |
| Operating costs | electricity, heating/cooling, maintenance, cleaning |
| Parking | number of spaces, cost per space |
| Initial fit-out | whether the landlord contributes or grants a rent-free period |
Every commercial lease in Greece falls under one of two regimes: the digital transaction duty, at 3.6% of the rent, or VAT. Which regime applies should be clarified from the start, because it directly affects the true monthly cost and is often a point of negotiation in its own right.
From the LOI to Heads of Terms: what to agree before signing
A Letter of Intent (LOI) signals the tenant's intention to open discussions about the space. It should not, however, substitute for the key terms of the deal.
Heads of Terms is the stage where the commercial points need to be captured clearly, before the final legal process begins.
At a minimum, the following should be settled:
- the rent, the term and the deposit
- rent indexation and any rent-free period
- the delivery condition and delivery date
- fit-out responsibilities
- parking spaces and any storage areas
- a possible break option
- the permitted use and any right to sublet
For new commercial leases, the legal minimum term is three years. A longer term can be freely agreed between the parties.
In larger lettings, most problems don't start in the lease document. They start because the Heads of Terms were vague. For the full legal framework of commercial leases, see our guide to commercial lease agreements in Greece.
Technical and legal due diligence before signing
Technical due diligence: examines whether the space can be used as an office, the actual floor areas, the M&E installations, fire safety, the lifts and the scope for fit-out.
Legal due diligence: examines ownership status, the right to lease, the building's regulations, the terms of the contract and any break rights.
Due diligence belongs after Heads of Terms and before the final signature — not once the company has already decided and is rushing to move in. Its purpose is to make sure the company knows exactly what it is leasing, and on what terms.
Negotiating an office lease: where the deal is really made
Good negotiation isn't just about pushing down the €/sqm. A deal can be better because it reduces risk, buys installation time or protects the company if its needs change. Points worth negotiating: rent, term, deposit, indexation, rent-free period, delivery condition, break option, reinstatement obligations at the end of the term.
Handover and moving in
Before moving in, there should be a clear picture of the handover protocol, photographic records, keys and access cards, the condition of heating and cooling systems, any outstanding landlord works, the rent commencement date and the actual move-in date.
Handover isn't the end of the deal. It's the beginning of the office's real use.
A good office lease isn't judged on the day of signing. It's judged in the months that follow: whether the space works, whether the cost is predictable, and whether the company can grow without another upheaval.
