When you start planning interiors, one of the first decisions is how you want to work with a designer. Broadly, there are two options. A turnkey firm designs, manufactures, executes and hands over the finished home, so you get the keys to a ready space. A design-only service gives you drawings, 3D views and specifications, and you hire carpenters, electricians, painters and suppliers yourself to build it.
Both approaches can work well in Kolkata. The right choice depends on your budget, your time, how involved you want to be and the complexity of the project. Here is an honest comparison.
What Turnkey Interiors Include
A turnkey project typically covers:
- Site measurement and space planning.
- 2D layouts, 3D designs and material selection.
- A detailed, itemised quotation.
- Manufacturing of modular furniture such as kitchens, wardrobes and TV units.
- Civil, electrical, plumbing, false ceiling and painting work.
- Coordination of all trades and site supervision.
- Installation, cleaning and handover, usually with a warranty.
You deal with one team and one contract, and the firm is responsible for the outcome.
What Design-Only Services Include
A design-only service usually covers:
- Site measurement and space planning.
- 2D layouts, 3D designs and working drawings.
- Material and finish specifications.
- Sometimes a few site visits to check progress.
You are responsible for hiring and managing everyone who builds the design, buying materials, and resolving issues on site.
Comparing the Two
Cost
Design-only looks cheaper at first because you pay only the design fee and then buy materials and labour directly. However, homeowners often underestimate the hidden costs: material wastage, rework when trades do not coordinate, multiple trips to suppliers, and delays that keep you paying rent or EMIs longer. Turnkey firms include their margin in the quote, but they also buy materials in bulk and manage wastage. For many Kolkata families, the final difference is smaller than expected. Our interior cost guide explains typical budgets.
Time and effort
This is where turnkey clearly wins. Managing a carpenter, an electrician, a plumber, a false ceiling team, a painter and multiple suppliers means daily phone calls, frequent site visits and constant decisions. For working professionals, NRIs and families with elders or young children, this is often not practical.
Quality and consistency
With turnkey, one team is accountable for how everything fits together, such as the ceiling lining up with the wardrobe, or the electrical points matching the TV unit. With design-only, quality depends on the skill of each individual contractor and how well they follow the drawings. Factory-made modular furniture in turnkey projects also tends to be more precise than on-site carpentry.
Control and flexibility
Design-only gives you more control over each vendor and each purchase. If you enjoy sourcing materials, negotiating with suppliers and being on site, you may prefer this. Turnkey gives you control at the design and material selection stage, and then the firm executes.
Accountability and warranty
With turnkey, if a drawer breaks or a ceiling cracks, you call one number. With design-only, you must track down the specific contractor, who may not be available or may blame another trade.
Who Should Choose Turnkey?
- Busy professionals who cannot visit the site often.
- Families moving into a new flat in New Town, Rajarhat or along the Bypass who want a fixed timeline.
- NRIs and clients living outside Kolkata.
- Anyone doing a full home with a kitchen, wardrobes, ceilings and painting.
- Homeowners who want a single warranty and point of contact.
Who Might Prefer Design-Only?
- Homeowners with trusted carpenters and contractors they have worked with before.
- People with the time and interest to supervise daily.
- Small projects such as one room, a mandir or a feature wall, where coordination is simple.
- Clients who want professional guidance but plan to build gradually over a long period.
A Middle Path
Some firms, including ours, offer flexible models. For example, we can manufacture and install your modular kitchen and wardrobes while you manage painting with your own painter, or provide design and supervision for a renovation where you already have a civil contractor. Discuss your situation openly with your designer to find the right balance.
Questions to Ask Before Deciding
- What exactly is included and excluded in each option?
- Who is responsible if the timeline slips?
- How many site visits are included in a design-only package?
- Is there a warranty, and what does it cover?
- How are payments linked to progress?
