Office Fit-Out & Workplace Design in Turkey

OFFICE FIT-OUT & COMMERCIAL INTERIOR SOLUTIONS

Our office fit-out service transforms shell & core or existing workplaces into fully functional, efficient and professionally designed environments. Sonraki delivers integrated planning, interior design and construction services aligned with international workplace standards.

We consider not only spatial aesthetics but also workflow efficiency, employee comfort, operational performance and client experience. From early layout decisions to final delivery, every stage is managed through a structured and controlled process.

Operating from Istanbul with international project experience, we support companies establishing or upgrading offices across Turkey as well as clients managing projects remotely.

Office Projects Begin With Planning, Not Construction

Successful workplaces start with understanding how a business operates. Before design begins, we analyse organisational structure, team workflows, technology usage, visitor circulation and operational requirements.

Based on this analysis, spatial layouts are developed to support both business goals and daily user experience.

Shell & core office projects and renovation of existing workplaces require different technical strategies. Each project is therefore evaluated according to building conditions, future growth plans and operational needs.

Scope of Office Fit-Out Services

Workplace planning and workflow strategy
Interior architectural design and material selection
Electrical, mechanical, HVAC and data infrastructure coordination
Fixed, bespoke and loose furniture integration
Full construction execution and project management

Beyond offices, the same fit-out methodology is applied to clinics, restaurants, hospitality venues and hotel environments, where operational efficiency and technical coordination are equally critical.

Understanding CAT A, CAT B and CAT C Offices

CAT classifications define the level of completion of an office space and determine the scope of fit-out required. This system is internationally recognised and increasingly used in Turkey’s commercial real estate market.

Correctly identifying the CAT level allows accurate budgeting and efficient project planning.

CAT A OFFICE?

CAT A offices are delivered with base building infrastructure completed but without tenant-specific interior arrangements.

Typically includes:

Main mechanical and electrical systems
Raised floors or base flooring
Suspended ceilings and basic lighting
No internal partitions or workplace layout

CAT A spaces require full interior planning and fit-out before occupancy.

CAT B OFFICE?

CAT B offices are fully customised workplaces designed and completed for a specific company.

Includes:

Workplace layout and partitions
Meeting rooms and collaborative areas
Acoustic, lighting and interior finishes
Integrated furniture and branding elements

CAT B fit-out transforms a space into a fully operational working environment reflecting company culture and operational needs.

CAT C OFFICE?

CAT C refers to refurbishment or reconfiguration of existing offices for new tenants or evolving organisational needs.

Typically involves:

Existing space analysis
Layout redesign
Infrastructure upgrades
Interior renovation and modernisation

These projects require careful planning to balance cost efficiency with operational continuity.

How we work?

1. Do you provide fit-out services for shell & core offices?

Yes. We deliver turnkey fit-out solutions for shell & core office spaces, managing planning, design and construction from start to completion.

2. I want to renovate my existing office — is that considered fit-out?

Yes. Renovation and workplace reconfiguration projects fall under CAT C fit-out services and begin with a detailed assessment of the existing space.

3. Is office design only about aesthetics?

No. Workplace projects balance visual identity with productivity, ergonomics, acoustics, lighting performance, equipment placement and overall user experience.

4. Do you work on international office projects?

Yes. In addition to projects across Turkey, we support companies opening offices in the UK under CDM coordination principles and provide design, procurement and implementation support for projects in Europe, Dubai and the Middle East.

5. Is it necessary to commission design and construction together?

No. Clients may choose design-only services or implementation based on existing concepts. However, projects managed through a single integrated team typically achieve better efficiency and cost control.
