Project design focuses on the complete, functional design of business spaces, while interior design focuses more on aesthetics and atmosphere. Project design takes into account work processes, ergonomics, and the practical needs of employees. The difference lies mainly in the approach: project design is systematic and focused on optimal functionality, while interior design is more creative and visually oriented.

What is the difference between project design and regular interior design?

Project design is a systematic approach in which the complete design of business spaces is approached from the perspective of functionality and work processes. You get a total solution that takes into account how people work, move, and collaborate in the space.

Interior design, on the other hand, focuses primarily on the visual and aesthetic aspects of a space. An interior designer thinks mainly about colors, styles, atmosphere, and how everything looks beautiful. That is important, of course, but it is a different perspective.

The main difference lies in the objective. In project design, the central question is: "How can we optimize this space for the people who work there?" In interior design, the main question is more: "How can we make this space beautiful and inspiring?"

Project design also takes technical aspects such as cabling, lighting, acoustics, and ventilation into account. These elements are incorporated into the design from the outset, rather than being added afterwards.

When do you need project design instead of an interior designer?

You need project design when you are dealing with complex business spaces where functionality is paramount. This applies especially to offices, workshops, and other commercial spaces where productivity and efficiency are important.

Some specific situations in which project design is the better choice:

  • You are setting up a completely new office with multiple workstations.
  • There are specific ergonomic requirements due to the type of work.
  • You are dealing with technical installations and cabling.
  • The project has a tight schedule and budget.
  • You want everything from a single source: from design to delivery

Interior design is more suitable for situations where aesthetics are paramount, such as homes, restaurants, or retail environments. In these cases, the focus is more on creating atmosphere than on optimizing work processes.

Scale also plays a role. For large projects with many workstations, project design is more practical because everything is coordinated. For smaller spaces or individual rooms, an interior designer may suffice.

How does the process of project design differ from interior design?

The project design process follows a structured step-by-step plan that begins with a thorough analysis of work processes and ends with a ready-to-use work environment. This differs significantly from the more creative approach of interior design.

When designing a project, you start with a comprehensive inventory. The number of workstations, the type of work, the desired atmosphere, and practical matters such as storage and meeting rooms are all taken into account. This information forms the basis for the design.

You will then receive a detailed 3D design in which everything has been worked out: from furniture selection to the exact placement of electrical outlets. You will see exactly what the space will look like before anything is ordered.

The implementation is fully coordinated. All suppliers, technicians, and other parties involved are managed from a single point. All you have to do is hand over the key, and you will receive a ready-to-use space in return.

Interior design is often more iterative, involving extensive consultation on colors, materials, and styles. The process is more creative, but also less predictable in terms of planning and budget.

What does project design cost compared to interior design?

Project design may seem more expensive at first, but you get a complete package that includes everything. The total investment is often more cost-effective than if you were to organize everything separately.

With project design, you pay for:

  • Design and 3D visualization
  • Project coordination and planning
  • All furniture and interior design elements
  • Assembly and installation
  • Often also warranty and service

Interior design usually only covers the design work. All purchases, coordination, and implementation are then at your expense. This can ultimately prove more expensive due to inefficiency and errors.

The major advantage of project design is cost transparency. You know exactly where you stand in advance. With interior design, costs can mount up because the design process takes longer or because changes are made along the way.

For commercial spaces, project design is often more cost-effective because everything is done properly in one go. You avoid duplication of work and get professional quality at competitive prices.

Frequently asked questions

How long does an average project design project take?

A project design project usually takes 4-8 weeks from design to delivery, depending on its size and complexity. The design phase takes 1-2 weeks, followed by 2-4 weeks for production and delivery. Advance planning is crucial to avoid delays.

Can I still make changes during the project?

Minor adjustments are usually still possible during the design phase, but once the 3D design has been approved, changes become costly and time-consuming. That is why we invest a lot of time in the preparation phase to ensure that everything is properly coordinated. Late changes can delay the project by 1-3 weeks.

What happens if the delivered furniture does not fit or is damaged?

We check everything in advance with precise 3D designs and measurements, virtually eliminating any fitting problems. If something does go wrong, we will resolve it within 48 hours at no extra cost. Our warranty covers both product defects and installation issues.

Do I need to arrange for technical connections such as power and internet myself?

We advise on the necessary connections and can often arrange these through our network partners. For more complex installations, we work with specialized technicians. It is useful to discuss technical requirements early in the process so that everything can be coordinated.

Can I also integrate used or existing furniture into the new design?

Certainly, we always first look at what can be reused from your current interior. High-quality existing furniture can be easily integrated into the new design. This saves costs and is more sustainable, provided that the furniture still functions well and fits in with the new layout.

How can I ensure that my employees are satisfied with the new layout?

Involve your employees in the process from the outset by identifying their wishes and working habits. We often organize a presentation of the 3D design where the team can provide feedback. Good preparation and communication prevents resistance and ensures support.

What if my business grows and I need more workspaces?

We always design with future growth in mind by choosing modular solutions and creating flexible layouts. Many of our furniture brands offer expansion options with the same style and quality. A good project design grows with your business.
