Point of contact, start to handover
A foundation, not a founding date
1958Polstar Engineers & Contractors has been executing civil and engineering works since 1958 — more than six decades of building things that had to stand up, on time and to spec.
Interiovation, founded in 2018, is the interiors studio built on that foundation. Younger as a name, but backed by a supply chain, crews and discipline that predate most of our competitors.

The questions every client asks first
Short answers here, honest detail in the Journal — the same guides we send clients before a first meeting.
What does turnkey interior contracting include?
One contract and one point of contact: the same company designs the space, quotes it as a single itemised number, procures every material, executes every trade, and hands over a finished, usable space. If the built space doesn't match what was quoted, there is exactly one party accountable — not two parties each holding half the story.
What turnkey contracting means, in full →How long does a full home interior take in Delhi?
A full home interior follows a fairly predictable sequence — design and drawings (2–4 weeks), civil work, electrical, flooring, then carpentry installation (3–5 weeks, typically the longest single phase) through to snagging and handover. For an occupied 2–3BHK renovation, a realistic timeline is 8 to 14 weeks. Carpentry density — how much built-in furniture you specify — changes the total more than any other factor.
The occupied-home renovation timeline →What does interior fit-out cost per sq ft in Delhi?
Indicative ranges: design and drawings run ₹80–150 per sq ft, execution-only interior fit-out ₹1,200–1,900 per sq ft, and turnkey design + build ₹1,500–2,500 per sq ft depending on scope and finish level. For a 1,200 sq ft flat, turnkey at these bands works out to roughly ₹18–30 lakh. Always compare itemised quotes, not bottom-line numbers.
The full cost breakdown →Is labour-rate contracting cheaper than turnkey?
Not always. It's cheaper on the quoted number because you buy materials yourself and avoid contractor margin — but that holds only for well-scoped, well-timed projects where you absorb the procurement work without mistakes. Once you factor in wastage, delays, rework risk and your own coordination time, the gap narrows or reverses on many real projects.
