How does the turnkey interior design process work? Drawing on Kaya + Partners' hands-on experience in Ankara, we walk you through the 5 stages from brief to handover, what gets designed at each stage, and how long each one takes.
Turnkey interior architecture is a holistic service model in which the entire process, from the first design sketch to the last screw of the furniture, is managed by a single studio. The client works with a single point of contact; design, fabrication and site coordination no longer exist as disconnected pieces. In this article, we walk through the 5-stage process we follow in our interior architecture work in Ankara, exactly what is produced at each stage, and realistic timelines.
Stage 1 — Discovery, Brief and Analysis
Every project begins by listening to the space and its users. In our first meeting, we discuss your lifestyle, your needs, your budget and your expected timeline. We then inspect the existing condition of the space on site, identifying technical realities such as dimensions, light, building services and the structural system.
- Space programme and user analysis
- On-site measured survey (existing conditions)
- Preliminary budget and project schedule
Duration: Typically 3-7 days.
Stage 2 — Concept Design
The collected data is translated into a design language. We prepare concept proposals that define the spatial arrangement, circulation, material palette and atmosphere. At this stage, we refine the idea together through moodboards, floor plan alternatives and 3D visualizations. Our approach to villa design for residences and office interior design for corporate spaces takes shape at this stage.
- Concept and moodboard
- Floor plan / layout alternatives
- 3D modeling and photorealistic renderings
Duration: 1-2 weeks.
Stage 3 — Construction Documents and Detailing
The approved concept is developed into a project that can be built on site. Dimensioned drawings for all joinery and fabrication, furniture details, lighting and electrical plans, and material and fixture schedules are prepared. This is the most critical step, as it minimizes unexpected costs and revisions.
- Construction drawings and fabrication details
- Lighting, electrical and plumbing plans
- Material, fixture and quantity take-off schedules
Duration: 4-8 weeks, depending on project scale.
Stage 4 — Site Implementation and Fabrication
This is where the real difference of the turnkey model becomes clear: we take on fabrication, procurement and site coordination. Craft teams, suppliers and fabrication workshops are managed according to the project details, so the client doesn't have to deal with individual contractors one by one. Quality and schedule are kept under control through regular site supervision.
- Fabrication and procurement management
- Coordination of craftsmen and workshops
- Regular site supervision and progress reports
Duration: Varies with scope; 6-16 weeks on average.
Stage 5 — Handover and Aftercare
Once all work is complete, we hand over the space in full. Every detail is reviewed with a pre-handover punch list. After handover, we continue to provide support under warranty.
- Pre-handover punch list
- Completion of outstanding items and touch-ups
- Post-handover support and warranty

Frequently Asked Questions
What is turnkey interior architecture?
Turnkey interior architecture is a holistic service model in which the entire process, from the first design sketch to the last screw of the furniture, is managed by a single studio. The client works with a single point of contact. Design, fabrication and site coordination no longer exist as disconnected pieces; the studio that designs the space also takes on fabrication, procurement and site coordination.
What are the stages of a turnkey interior design process?
A turnkey interior design process has five stages: discovery, brief and analysis; concept design; construction documents and detailing; site implementation and fabrication; and handover and aftercare. The first stage produces a space programme and an on-site measured survey, the concept stage moodboards and 3D visualizations. On site, fabrication and procurement are managed; before handover every detail is checked against a punch list, and support continues under warranty.
How long does a turnkey interior design project take?
In a turnkey process the duration varies by stage: discovery, brief and analysis typically takes 3-7 days, concept design 1-2 weeks, construction documents 4-8 weeks, and site implementation and fabrication 6-16 weeks on average. The length of the construction documents stage depends on the scale of the project, and that of the site stage on the scope of the work.
What is the advantage of the turnkey model?
The main advantage of the turnkey model is that design and implementation sit within the same team: responsibility rests with one party, there are fewer surprises in time and cost, and the integrity of the design is preserved. Because craft teams, suppliers and workshops are managed according to the project details, the client doesn't deal with individual contractors, and regular site supervision keeps quality and schedule under control.
Why are construction documents important in a turnkey project?
Construction documents are the most critical step in a turnkey process, because they turn the approved concept into a project that can be built on site and minimize unexpected costs and revisions. They include dimensioned drawings for all fabrication, furniture details, lighting, electrical and plumbing plans, and material, fixture and quantity schedules. This stage takes 4-8 weeks, depending on project scale.
