Registration lapsed

This project’s MahaRERA registration has lapsed— it expired and was not renewed. A lapsed project may be stalled, finished-but-not-updated, or abandoned; the record stops here and RERA’s ongoing protections may no longer apply. Confirm the current status directly with MahaRERA before you rely on anything below.

These are sums of what the builder has put on the public record across their projects — a sense of how big a builder this is, not build quality and not whether they finish on time.

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.

Satellite view of the site

Google Open Buildings, 2016–2023 · Sentinel-2 imagery

Open ground within ~20 m of the recorded location until 2017; a building is first visible in 2018 and is about 97 m tall by 2023.

Satellite view, year by year

loading 2023

Height estimated by a model from satellite imagery — not a survey, and the series ends in 2023. The dashed shape is within ~20 m of the filed location.

Satellite photographs of the same ground

Mar 2017

Feb 2026

Sentinel-2, 10 m per pixel — about 400 m of ground across. Each frame is one dry-season day, so haze can dull a site.

How to read this

  • A building is first visible in 2018.
  • This state publishes a point, not a plot outline, so the shape is a circle around it. A neighbour’s building can fall inside.
  • Site is a ~20 m circle around the RERA point, not a plot outline: buildings inside it may belong to neighbours.

Government Guidance Rate

Maharashtra registration department

In Maharashtra it’s called the ready reckoner rate.

No government guidance rate is shown for this project.

Mumbai's ready reckoner is addressed by city survey (CTS) number inside a named village, and this filing declares neither — its village field holds a ward or a taluka. Naming one of the zones around it would be a guess, and inside a single division the rates run three-fold.

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

Planning authority

MahaRERA · Approved building plan

Maharashtra Housing and Area Development Authority (MHADA)

Housing Authority
Building Permit
Survey no. CTS No 88 Pt

The promised possession date (31 Dec 2021) has passed. This record can’t confirm whether the project was completed — that sign-off is the occupancy certificate, below.

The occupancy certificate — the proof that isn’t here

An approved plan is the government’s approval to build. It is not proof the project was built to that plan. That sign-off is the Occupancy Certificate (OC) — issued by the planning authority, the same body that approved the plan, not by RERA— and it isn’t in this record. Ask the builder for it, or check with the authority. Without an OC, banks may decline home loans, and any deviation from the approved plan carries penalty or demolition risk.

Volume and mix are context, not a verdict — a busier body isn’t a safer project. And this counts RERA-registered projects on Horizon’s record, not all construction.

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.
