This Greater Noida Map guide explains the plots, roads and facilities in detail. Sigma 3 and Sigma 4 are the newer, more compact Sigma sectors. Unlike Sigma 1 and Sigma 2, they use small 200 to 220 sq m plots grouped into named estates, with large group housing plots, broad green belts and very wide commercial belts along the main roads.
This guide reads both official layout plans: plot sizes, estates, group housing, parks and roads. The map pages are on our Sigma 3 map page and Sigma 4 map page.

Sigma 3: 348 Plots in Two Estates
The Sigma 3 plan states a total of 348 plots, all 20 m × 10 m (200 sq m, about 2,153 sq ft), split between two estates:
- Cassia estate (orange) on the west side.
- Nodola estate (yellow) in the centre and east.
Below the estates sit two large group housing plots of 2.96 ha and 4 ha, both planned at 243 persons per hectare, with a row of facility sites between them — a nursery school, creche, nursing home and convenience shopping. Roads and boundaries:
- An 80 m wide road corridor on the north.
- 60 m wide road corridors on the east and south.
- A proposed 60 m road with a 40 m green belt on the west.
- Two 50 m wide commercial belts (1.27 ha and 1.15 ha) along the east road.
- 45 m wide green belts below the group housing and several parks of 0.31 to 0.88 ha inside.
Sigma 4: Three Estates Around a Central Park
Sigma 4 uses a slightly bigger plot, 20 m × 11 m (220 sq m, about 2,368 sq ft), across three named estates:
- Austonia estate (salmon) in the north-east.
- Chorosia estate (yellow) in the north-west.
- Cassia Semia estate (purple) in the centre-west.
| Feature | Sigma 4 plan |
|---|---|
| Group housing | 3.45 ha and 5.3 ha at 299 persons per hectare |
| Central park | 1.74 ha, plus parks of 0.65 ha and 0.54 ha |
| Commercial belts | 100 m wide, 2.66 ha and 3.74 ha, along the east |
| Green belts | 75 m wide on the west (2.08 ha and 2.16 ha); proposed 45 m belts in the south |
| Main roads | 130 m road on the east, 80 m on the north, 60 m on the south and west |
| Neighbours | Sigma 2 to the north, Sigma 3 to the west, Sigma 1 to the north-west |
A small facility zone in the middle carries a nursery school, nursing home, convenience shopping and a creche.
Sigma 3 vs Sigma 4: Quick Comparison
| Feature | Sigma 3 | Sigma 4 |
|---|---|---|
| Plot size | 200 sq m (20 m × 10 m) | 220 sq m (20 m × 11 m) |
| Estates | Cassia, Nodola | Austonia, Chorosia, Cassia Semia |
| Group housing | 6.96 ha across two plots (243 PPHA) | 8.75 ha across two plots (299 PPHA) |
| Commercial belt | 50 m wide | 100 m wide |
| Widest road | 80 m | 130 m |
Sigma 4 has the wider commercial belts and the 130 m road, so it is the better pick if you value long-term commercial potential. Sigma 3 has a slightly smaller plot and a lower group-housing density. For bigger plots, look at Sigma 1 and Sigma 2.
What to Check Before You Buy in Sigma 3 or Sigma 4
- Confirm the estate name and plot number on the layout and in your papers.
- Check whether the plot faces a park, a green belt or a 12 m internal road.
- Note the proximity to group housing plots and drains shown on the plan.
- For Sigma 3, check the status of the proposed 60 m western road and green belt.
- Ask for the latest dues and possession status for the plot or project.
