Interiors built on honesty.
Royal Castle Interio started with one belief: a home should be exactly what was promised — no hidden costs, no surprise delays, no cut corners once the ink is dry. Everything we've built since follows from that.
Built to fix what
the industry got wrong
"We kept meeting families who'd been burned by their last interior contractor — quotes that doubled, timelines that tripled, work that started falling apart within a year."
That gap between what's promised and what's delivered is the entire reason this company exists. We built Royal Castle Interio around three non-negotiables: pricing you can see in writing before work begins, a 3D render of your home before a single wall is touched, and a 30-year warranty* on every piece of furniture we install — because if we're confident in the work, we should be willing to stand behind it that long.
Today, from 2BHKs in Salt Lake to full duplexes in Alipore, we've carried that same standard into every home across Kolkata we've worked on.
*Terms and conditions apply. Ask your design consultant for full warranty details.
A promise I make to every family we work with
"We don't just design rooms. We design the life you want to live inside them — and we don't consider a project finished until you'd invite anyone over without a second thought."
Every milestone was a promise kept — not just a number reached.
Prasenjit Ghosh starts Royal Castle Interio in Kolkata with one non-negotiable rule: the final bill matches the first quote, to the rupee — no exceptions.
We cross our 100th project without ever revising a signed quote upward — proving the pricing promise wasn't a launch-phase gimmick, it was the actual business model.
No more outsourced site teams or subcontractor guesswork. Design and execution move under one roof, so the people who plan your home are accountable for building it too.
From Salt Lake to Behala, Garia to Rajarhat — every one of our 1200+ projects has followed the exact same promise we started with in 2014.
The four things we never negotiate on.
Transparency
Every cost is quoted upfront, in writing. What you're shown is what you pay — no surprise line items mid-project.
Craftsmanship
Every piece is built to a standard that earns a 30-year warranty — not just a design that looks good on day one.
Punctuality
Your project is scheduled from day one and tracked against that schedule — because your time matters as much as your budget.
Honesty
If something won't work in your space or your budget, we'll tell you before you spend a rupee on it — not after.
