Every project Horizon has read from this builder, oldest first on the timeline. Dates are the project’s start (where filed) and target-completion dates on the RERA filing; delivery isn’t reported here.

Government Guidance Rate

West Bengal registration department

In West Bengal it’s called the market value — the registration directorate's figure, not a sale price.

No government guidance rate is shown for this project.

West Bengal's government guidance rates aren't in Horizon's record yet.

That is a statement about what Horizon can place — not a sign that no rate exists, and not a signal about the project.

Complaints & litigation

WBRERA · public record

Complaints register

Not published. WBRERA doesn’t publish a complaints register in the record Horizon reads.

So there is nothing to count here — which is not the same as nothing having been filed.

Flags on the record

WBRERA's list · builder's declaration

Defaulter list: This developer appears on WBRERA's defaulter listworth checking

The defaulter line is WBRERA's own list; a litigation line is the builder's declaration. Either is worth checking with WBRERA — neither is a verdict.

Not a verdict. A complaint can be dismissed and a case can be won; an order can be appealed.

Not a clean bill. An empty record means nothing was filed with WBRERA, or that this register doesn’t publish it — never that nothing happened.

What this record cannot tell you

Build quality — no filing records how well it was actually built.
Private disputes — only complaints escalated to the authority appear here.
What it will be worth — the record is the past; it does not price the future.
Construction progress — WBRERA does not publish quarterly progress reports. How far along it actually is cannot be read here.
Complaints — WBRERA does not publish a complaints register. This read cannot speak to them either way.
Escrow — WBRERA does not publish escrow declarations. Whether buyer money is ring-fenced cannot be read here.
