What to consider when choosing a design firm: a practical guide for companies and investors
Choosing the right design firm is one of the most critical decisions when furnishing an apartment, a house, or a commercial space. The quality of the design determines not only the look of the interior but, more importantly, its functionality, user comfort, and overall execution costs. Well-planned interior design can streamline a team’s daily operations, shorten the investment process, and help prevent costly mistakes.
So, how do you choose a studio that will act as a true partner rather than just a provider of visualizations? How do you select the right design firm? We answer these questions and outline the key considerations in the guide below.

What exactly is a design firm?
What exactly is a design firm?
Today, the term "design firm" can encompass a wide range of specializations. Some companies handle comprehensive building design—covering everything from structural engineering to utility systems. Others, such as interior design studios or specialized design practices, focus primarily on space planning and tailoring environments to meet user needs.
For private investors and companies alike, it is often this second category that proves most critical. The interior architect and their team are responsible for the function, aesthetics, and overall atmosphere of a space. Such a design studio does more than just suggest styles or color palettes; they design the very way we interact with and navigate a space on a daily basis.
TENGO Design operates precisely on this model as an interior design studio. We deliver projects for apartments and houses, as well as office spaces, with specialized expertise in commercial interiors.

The role of a design studio in practice
The role of a design studio in practice
For many, working with a designer is associated solely with pretty visualizations. In reality, a professional office or residential project is a far more complex process.
It all begins with a consultation: an in-depth conversation and needs analysis. An interior architect must understand how many people will use the space, the team’s work style, and the aesthetic and budgetary expectations. Only then can a functional layout for the office or home be developed. This involves the logical arrangement of rooms, workstations, meeting zones, and relaxation areas. Effective space planning is critical to future functionality, and it’s at this stage that the design studio strives to optimize every available square meter.
The next step involves office or interior designs presented as floor plans and 3D models. Thanks to photorealistic visualizations, the client can see the final result before any work even begins. This is the perfect stage to easily implement changes and refine details. Instead of making adjustments later on-site during construction, the client can visualize the finished project before making any major purchases.
A top-tier design firm also prepares detailed technical documentation along with material and equipment lists. They support the client throughout the procurement process. Increasingly, investors are opting for turnkey office projects. This is the most comprehensive service, encompassing the design, furniture supply, and project management or site supervision. This approach shortens the investment timeline, provides greater budget control, and offers the highest level of convenience for the investor.

Office & Interior design: what are the costs?
Office & Interior design: what are the costs?
Cost is naturally a primary consideration at the start of any project. However, it’s important to note that office design fees are rarely one-size-fits-all. Every project is quoted individually, as the final investment depends on a variety of unique factors.
The most significant factor is square footage. While most studios use a per-square-foot (or per-square-meter) rate, these fees scale with the project's complexity. For instance, a small boutique space requires a different pricing structure than a large-scale corporate office involving structural changes, MEP (mechanical, electrical, plumbing) updates, and specialized acoustic solutions.
In practice, a well-executed design often saves more than it costs. Informed material choices, access to vetted suppliers, and the prevention of costly construction errors provide a tangible return on your investment, significantly impacting the overall project budget.

When selecting a partner, it’s essential to look beyond the fee alone. Experience and portfolio depth are far more telling. A firm with a proven track record of successful office fit-outs and innovative designs for reputable brands demonstrates the expertise required to manage high-stakes projects and demanding clients.

Reputation and workflow are equally vital. A top-tier architectural firm—whether in Warsaw or any other major hub—should provide clear communication regarding the project timeline, scope, and division of responsibility. It is also worth ensuring that the team works with a vetted network of local contractors and manufacturers rather than relying on anonymous overseas suppliers. Prioritizing local partners ensures shorter lead times, superior after-sales service, and tighter quality control. This approach also aligns with sustainable practices: localized logistics significantly reduce carbon emissions while supporting the local community.
Industry recognition—including client testimonials, features in leading design publications, and partnerships at major trade events—is equally significant. These are clear indicators of a studio’s credibility and the high level of trust it has earned within the market.
When choosing a design studio, pay close attention to the following:
- cost
- experience & portfolio
- high-profile projects for global & market-leading brands
- transparent collaboration process, schedule, and responsibilities
- transparent approach to the budget
- practical delivery timelines
- collaboration with trusted local contractors and reputable manufacturers
- high-quality materials and furnishings, not just the lowest cost
- warranty period and terms & conditions
- client testimonials and project feedback
- presence in industry media, awards, and partnerships at major events
- full-service approach

Why hire a design studio instead of doing it yourself?
Designing your office or home yourself might seem cost-effective, yet it frequently causes functional mistakes, wrong purchases, and timeline setbacks. Hiring a professional ensures expert knowledge, experience, and technological insight.
Partnering with an experienced design studio ensures peace of mind. The finished space will be both visually appealing and functional, fully compliant with regulations, and adaptable to your company’s future requirements.
