Startup office spaces are often where it all begins for emerging companies. Choosing the right office is one of the most defining decisions for any new business.

The space you select doesn’t just determine where your team sits. It shapes your culture, productivity, and even your brand identity.

For startups in Belgium, from the heart of Brussels to the innovation hubs of Antwerp and Turnhout, the question isn’t whether you need a space. It’s which kind of space is right for you.

Across the Belgian market, the average cost of startup space rental depends on flexibility, size, and location.

A coworking space for startups typically ranges from €200 to €300 per month per desk, giving founders affordable access to a professional setup. Meanwhile, private offices can cost from €500 up to €1,000+ per month per person in premium Brussels or Antwerp locations.

Virtual offices and registered business addresses start from under €70 per month, providing a lean option for early-stage ventures that don’t yet need a full-time office.

These figures highlight a crucial advantage for modern entrepreneurs. Professional, fully serviced offices are no longer out of reach. Flexible workspace solutions now allow startups to scale at their own pace, paying only for what they actually use.

Added Value: The Real Difference

Beyond the essentials, what truly defines great startup office spaces in Belgium is the added value. These are the details that turn a functional space into a platform for growth.

Startups thrive when they are surrounded by other businesses, professionals, and institutions that inspire collaboration.

Proximity to key corporate areas, such as Brussels’ EU District or Antwerp’s business parks, gives young companies direct access to potential partners and clients.

Interoffices locations are chosen for these advantages. Each site is close to transportation, professional networks, and economic centres that help new businesses grow faster.

The added value doesn’t stop there

• Sustainable and ethical design ensures your workspace aligns with your values. Every building meets high energy efficiency standards and uses responsible materials.

• Noise management and smart layouts create the right balance between focus and communication. Acoustic materials and well-defined zones reduce distractions and improve comfort.

• Scalability and flexibility mean your office can evolve as your startup grows. You can expand from a coworking desk to a private office or custom suite without changing address.

These design choices make Interoffices more than just a workspace. They make it an ecosystem that supports innovation, wellbeing, and long-term success.

How Design Shapes Startup Culture and ROI

The best office spaces do more than hold teams. They shape how those teams think, create, and collaborate.

Research from Office Supermarket UK, BDC Magazine, and The World Economic Forum shows that design and furniture directly impact productivity and wellbeing. An ergonomic chair and well-lit workstation can reduce fatigue and improve focus.

Open, flexible layouts encourage teamwork, while private areas allow for deep, concentrated work.

Even the smallest details matter. Colours influence mood, and furniture placement affects communication. Don’t believe us? Just look at how this L.A office is using design to make work easier for its employees.

In the same vein, our flagship office based at the EU quarter of Brussels emulates these positives. From electric bike rental and clothes washing services to onsite parking with e chargers and so many more added value benefits.

What you get back from your space can often depend on your original intentions. If you want your workspace to be a social hub for clients and employees alike, then the design should reflect this. Setting clear aims regarding what you want to achieve from your space from the beginning is an important step to ensuring a high ROI from your workspace.

Startup Office Culture: The Ping Pong Table Effect

So now lets take a look at how the addition of just one item can add so much to your space. Think of the ping pong table as more than a fun accessory. It’s a tool for so many positives, from connection to exercise.

A great piece on Medium showcases how social and recreational spaces strengthen engagement and encourage creative thinking.

When teams interact informally, collaboration becomes easier. Strategic thinking improves, and people feel more connected to the company.

A startup’s culture often comes alive in its workspace. A lounge with character, a breakout zone, or branded décor can all express your mission and values.

The workspace becomes a living reflection of your brand, helping every visitor and employee understand who you are.

So from individual competitiveness to the team work of doubles, from settling disputes at the table to the general exercise and boost in reaction time – this one item works as a great learning tool for teams.

Apply the same thinking to your office space choices and your startup is sure to see huge wins on and off the table.

Your Space, Your Startup

Ultimately, startup office space is what you make of it. It’s not just about square meters or rent. It’s about creating an environment that matches your vision and helps your team grow.
