Satellite view of the site

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

A building already stood within ~26 m of the recorded location in 2016 — before this project started in 2025. The yearly view ends in 2023, so it does not cover this project's own construction; see the 2026 image.

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 ~26 m of the filed location.

Satellite photographs of the same ground

Mar 2017
Feb 2023
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 2016.
  • 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 ~26 m circle around the RERA point, not a plot outline: buildings inside it may belong to neighbours.
  • The yearly site view ends in 2023, before this project started in 2025.

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

Municipal Corporation of Greater Mumbai

Municipal Corporation · MCGM
Building Permit
Survey no. 307/39/B
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.

The approving body, at scale

Municipal Corporation of Greater Mumbai

Municipal corporation

Has approved 2,862 RERA projects — about 1 in 7 in Maharashtra, more than any other body in the state.

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.
