What has changed on this record
nothing recorded yet
When Estanzo first saw a difference - not proof RERA’s record changed that day.
Estanzo began recording changes to this record on 10 Aug 2026. Nothing has moved since. Anything that changed before that date is not on this list.
These dates are Estanzo’s, not UPRERA’s. They say when Estanzo last saw a field move - not when the authority last checked it, and not when the underlying fact changed. UPRERA does not re-serve every field on every run, so a field with no movement here has not necessarily been re-confirmed.What to verify and what to ask
1 not published
Fields UP-RERA has not published for this project. Coverage is uneven, so an absence is not evidence anything is wrong - only something this page cannot answer.
- No quarterly progress report is published for this project.Ask the promoter for the latest quarterly report filed and the construction percentage certified in it.
Common questions about I-Thum
Is I-Thum RERA registered?
Yes. I-Thum is registered with UPRERA under registration number UPRERAPRJ10363, registered on 13 Aug 2017. Estanzo reproduces that filing; it does not verify the work behind it.
Has I-Thum been completed?
UPRERA still lists I-Thum as Registered, so it is not shown as completed here. A completion certificate dated 24 Aug 2020 is on the record - RERA accepts these tower-wise, so one on file does not mean the whole project is complete.
Who is the builder of I-Thum?
GRANDSLAM DEVELOPERS PVT. LTD is the promoter entity that filed I-Thum with UPRERA (promoter RERA ID UPRERAPRM19252). RERA registers the legal entity behind a project, which may differ from the brand it is marketed under.
Does I-Thum have a RERA bank account?
Yes. The bank accounts filed with UPRERA for this project are listed on this page. Account details can change, so verify them against the official UPRERA source before making any payment.
Where is I-Thum located?
I-Thum is registered in Gautam Budh Nagar, as filed with UPRERA.
What configurations are available in I-Thum?
The unit plan filed with UPRERA lists OTHER. That is the approved plan, not a live availability list - RERA does not publish what is still unsold.
What is the carpet area of flats in I-Thum?
The approved unit plan filed with UPRERA runs from 11 to 475 m² of carpet area (about 120 to 5,110 ft²). Carpet area is the net usable floor area the RERA Act defines and the only area the authority holds - a built-up or super-area figure quoted elsewhere is a larger number measured a different way.
How many towers and units are planned in I-Thum?
The approved unit plan describes 2 blocks and 665 units. UPRERA publishes no separate tower or unit count, so both are counted from that plan.
How dense is I-Thum?
About 135 units per acre: 665 planned units across 4.94 acres (20,000 m²) as filed with UPRERA. Both figures are the authority's; the division is ours.
