The corridor epicenter, in one paragraph
Sector 22D on the Yamuna Expressway is the single most built-up residential pocket in the entire corridor — twelve named projects in this review, spanning every stage from a reported-sold-out registered launch to projects with no independently verifiable RERA number at all. Only three carry a fully transparent, live, directly-bookable cost sheet today: Gaur Chrysalis Phase 1 (registered, reported sold out), Eldeco Echoes of Eden (registered, under construction, Caelum tower open) and the three ACE Group filings (Terra/Edit/YXP, each separately registered). The rest — Codename Plume (now RERA-registered as Gaur Alaris, UPRERAPRJ950965/07/2026, though not yet independently re-confirmed by us on the portal) and Arihant Seasons 22D (reported-registered but not independently re-confirmed by us on the portal), County and Orion (no independently verifiable RERA number at all), ATS Allure (RERA now confirmed, but conflicting portal pricing and tower count), and Purvanchal Sunbliss and Greenbay The Monarque (RERA and promoter now confirmed directly on up-rera.in in follow-up reviews, but price and configuration figures still carry real, unreconciled gaps) — need a direct, personal verification step before any figure below is treated as current. That verification step is the entire point of this page.
Why Sector 22D, specifically
Every corridor guide on this site eventually points back here. Sector 22D sits closest to the operational stretch of the Yamuna Expressway approach to Noida International Airport, it was named in YEIDA's 2024 residual-plot land scheme, and — unlike Sectors 18 and 20 a few kilometres away, which show no named apartment supply in our review (see our four-sector buyer's guide) — it is where every major Yamuna Expressway developer has chosen to build. That concentration is exactly why buyers get confused here: multiple projects with similar-sounding “peacock,” “butterfly” and lifestyle-branded names, at least one project actively marketed under two different names (Gaur Chrysalis Phase 1 vs. “Chrysalis 2.0”/Plume), and price quotes that vary by thousands of rupees per sq.ft across portals for the same address. This page exists to put every one of them in a single, sourced table — not to pick a winner for you. For a faster, at-a-glance status check across the whole corridor — this sector and beyond — see our companion live status grid, updated independently of this editorial comparison.
Which is cheapest, which is ready first, which is “best” — answered first
Cheapest quoted entry: ACE Edit, from a reported ₹85.76 lakh — but that is a smaller-format unit, not a 3 BHK-for-3 BHK comparison. Among projects with transparent per-sq.ft pricing and a live RERA filing, Eldeco Echoes of Eden's 3 BHK from ₹1.44 Cr (₹9,300/sq.ft BSP, Caelum tower) is the clearest verified entry ticket today.
Closest to possession: ACE Terra, reported for December 2028, ahead of Greenbay The Monarque (Sep 2029), Purvanchal Sunbliss (Jan 2030), Gaur Chrysalis Phase 1 (Oct 2030) and Eldeco Echoes of Eden (Jan 2031) — all reported, RERA-filed target dates, not guarantees.
“Best”: we won't manufacture a single winner across twelve projects built for different buyers. Gaur Chrysalis Phase 1 is the demand proof-point (reported sold out); Eldeco Echoes of Eden is the one project combining a live RERA number, visible construction and directly bookable availability right now; Codename Plume is now RERA-registered as Gaur Alaris (UPRERAPRJ950965/07/2026); and County and Orion have no verifiable RERA number, while ATS Allure — RERA now confirmed, along with a 2023 delay order we dug up since — still carries a pricing/tower-count gap we're naming rather than smoothing over below.
The master matrix — one verified row per project
| Project | RERA status | Configs | Indicative price | Possession | Our take |
|---|---|---|---|---|---|
| Gaur Chrysalis (Ph. 1, original) | UPRERAPRJ622344/11/2025, granted 4 Nov 2025, promoter Gaursons Promoters Pvt Ltd. Confirmed | 3 BHK 1,910 sq.ft · 4 BHK 2,495 sq.ft (total/saleable) · 7 towers (B1–B7), G+33/34, ~11.8–12 acres, 952 units, butterfly theme, ~75,000 sq.ft clubhouse | Launch BSP ₹8,000/sq.ft, revised ₹11,000/sq.ft (eff. 22 Dec 2025, +37–38% in ~7 weeks, our calc) — indicative ₹1.98–2.64 Cr band post-revision Reported | Oct 2030 (per RERA filing) Reported | Reported sold out — the sector's demand proof-point. If you want this exact building, you're shopping resale, not fresh availability. |
| Gaur Alaris (formerly Codename Plume / “Chrysalis 2.0”) | RERA-registered — UPRERAPRJ950965/07/2026 (July 2026). Founder-stated | 3 BHK only, 1,550 sq.ft & 1,950 sq.ft (final) · 8 towers (Phase 1), ~11.8 acres, peacock theme, ~85,000 sq.ft clubhouse + 15,000 sq.ft terrace | Current BSP ₹8,499/sq.ft (launch was ₹12,000/sq.ft) — 3 BHK from ₹1.32 Cr* Reported | 09-06-2031 (Phase 1, per RERA registration) Founder-stated | Same family as Chrysalis, now separately registered under its own RERA number. Not yet independently re-confirmed by us on the portal — see our full Gaur Alaris review. |
| Eldeco Echoes of Eden | UPRERAPRJ125342/02/2026, promoter Eldeco Sohna Projects Limited. Confirmed | 3 BHK 1,550–1,850 sq.ft · 4 BHK/duplex 2,700–3,150 sq.ft · 3 towers (Haven, Elysian, Caelum), G+32, 5 acres, 558 units, VRV AC standard — 2 BHK sold out, Haven & Elysian fully booked | Current BSP ₹9,300/sq.ft (Caelum only; launch-era ₹8,999/sq.ft) — 3 BHK from ₹1.44 Cr, 4 BHK/penthouse ₹2.51–2.93 Cr Reported | Jan 2031, 30:40:30 construction-linked plan Confirmed | The only project here combining live RERA, visible construction and open direct booking today — our default answer for “ready-ish and verifiable now.” |
| ACE Terra | UPRERAPRJ683816/04/2024 Confirmed (ACE Group's own site, cross-page) | Per ACE's project listing — confirm current configuration and carpet area directly | From ₹2.63 Cr Reported | Dec 2028 Reported | Earliest reported possession date on this table — worth a look if timeline matters more than entry price. Full sourced review, incl. the registered promoter entity behind the “ACE” brand here: ACE Terra: Honest Review (2026). |
| ACE Edit | UPRERAPRJ467686/09/2025 Confirmed (ACE Group's own site) | Smaller-format configuration — verify against Terra/YXP before assuming a like-for-like comparison | From ₹85.76 lakh Reported | Not independently confirmed in this review Gap | Lowest headline price on this table by a wide margin — that's a smaller product, not a cheaper version of the same apartment. Confirm size before comparing BSP. |
| ACE YXP | UPRERAPRJ397607 Confirmed (ACE Group's own site) | Per ACE's project listing — confirm current configuration directly | From ₹1.50 Cr Reported | Not independently confirmed in this review Gap | Mid-tier ACE entry between Edit and Terra — same developer group, same “verify the current launch phase” caveat. |
| ATS Allure | UPRERAPRJ918, registered 31-07-2017, promoter ATS Realty Private Limited Confirmed (up-rera.in, direct) — since independently confirmed after this row was first published | 2 BHK & 3 BHK; portals disagree on tower count (2 vs. 8) and units (1,114–1,146), 8.48 acres consistent; RERA-filed carpet area 756–896 sq.ft. vs. portal super-built-up 753–1,350 sq.ft. Gap | Sources disagree materially — cited figures ranged from ₹1.15 Cr to ₹1.53 Cr for what may be different unit types or resale vs. primary listings Not independently verified | Largely possession-complete per portals; a Feb 2023 UP-RERA order found delivery still incomplete for 19 complainants as of that date and ordered possession within 60 days Confirmed (order) / Gap (current compliance) | The messiest data set on this table. Don't rely on any portal figure here — pull the live RERA filing and cost sheet directly before a site visit. We since dug further, including a 2023 UP-RERA delay order: ATS Allure: Honest Review (2026). |
| Purvanchal Sunbliss | UPRERAPRJ746863/04/2025, registered 8 Apr 2025, promoter Purvanchal Projects Private Limited Confirmed (up-rera.in, direct) — since independently confirmed after this row was first published | Studio to 4 BHK, 725–3,695 sq.ft per portals vs. a materially smaller carpet-area set (366–2,250 sq.ft.) per the project's own marketing site · 7 towers × 25 floors, 10.5 acres, 1,112 units Gap | ~₹10,000/sq.ft Reported | 29 Jan 2030 Confirmed | Widest configuration spread in the sector (studio through 4 BHK) and a promoter with a genuinely checkable NCR delivery record — but its own configuration figures conflict materially across sources. We dug further, including that delivery record: Purvanchal Sunbliss: Honest Review (2026). |
| Greenbay The Monarque | UPRERAPRJ710489/10/2025, promoter Green Bay Infrastructure Private Limited Confirmed (up-rera.in, direct) — since independently confirmed after this row was first published | 3.5 BHK & 4.5 BHK · ~314 reported units on 4.22 acres, part of the “Greenbay Golf Village” township | Not independently confirmed in this review Gap | 18 Sep 2029 Confirmed | Golf-course positioning is genuinely distinctive — and the golf/township amenities do sit under a separate, older RERA filing, not this one. We dug further, including the promoter's group affiliation: Greenbay The Monarque: Honest Review (2026). |
| County (Yamuna Expressway) | No RERA registration number surfaced in this review. Gap | 3, 4 & 5 BHK per developer marketing | Not published Gap | Not stated — reads as pre-launch/upcoming per developer marketing Gap | No independently verifiable RERA number anywhere in our source set. Treat as marketing material until a registration number is confirmed on up-rera.in. |
| Orion (Sector 22D) | No RERA registration number surfaced in this review. Gap | 3 BHK & 4 BHK, 1,800–3,000 sq.ft, 800 units, sited on an 11-acre parcel inside a marketed 100-acre township | “On request” — no public figure Gap | Not stated Gap | Least transparent listing on this table — no public price and no RERA number. Get both in writing before a site visit. |
| Arihant Seasons 22D | UPRERAPRJ974543/02/2026 Reported (portal listings; not independently confirmed by us on up-rera.in) | 3 BHK & 4 BHK, 1,600–3,500 sq.ft · 11–12 towers planned, ~11.8 acres (YEIDA e-auction, Oct 2024) | Pre-launch ~₹8,000/sq.ft → tentative ~₹10,000/sq.ft at launch Reported | Not stated — pre-launch pricing Gap | Newest land parcel in the set (Oct 2024 e-auction) and the largest tower count on paper — still pre-launch pricing; confirm the final sanctioned plan before relying on 11–12 towers. |
Legend: Confirmed = two or more independent sources agree, or the developer's own official site states it consistently across pages; Reported = one or more named portal/media sources, not independently re-confirmed by us against the live up-rera.in filing; Gap = no verifiable figure found — named, not estimated. Every RERA number above should be independently checked at up-rera.in before any booking; portal pricing moves between phases and is never a substitute for the live cost sheet.
Why we publish gaps instead of filling them Two rows above — County and Orion — carry a genuine RERA gap: no registration number we could independently surface. A third, ATS Allure, started the same way when this page first published; a follow-up review has since confirmed its RERA number directly (UPRERAPRJ918) and turned up a 2023 UP-RERA delay order, though its price and tower-count figures still conflict across portals. We could have rounded any of these off with a plausible-sounding estimate. We didn't, because a wrong number dressed up as confident advice is worse than an honest “verify this yourself” — and because the whole reason a page like this is useful is that every other figure on it earned its “Confirmed” or “Reported” tag rather than being assumed.
How Gaur Chrysalis, Chrysalis 2.0/Plume and Eldeco EOE relate to each other
Three names on this table cause almost all of the buyer confusion in Sector 22D, so it's worth stating plainly: Gaur Chrysalis Phase 1 and Codename Plume (widely marketed as “Chrysalis 2.0” or “Gaur Plume”) are two separate projects by the same developer group — Chrysalis is the registered, reported-sold-out butterfly-themed original; Plume is the peacock-themed sequel, now RERA-registered as Gaur Alaris (UPRERAPRJ950965/07/2026). Neither one's registration covers the other — see our dedicated Codename Plume review for the full disambiguation. A third Gaurs name worth keeping separate from both: Gaurs Studio Bento is a distinct studio-apartment launch at Sector 19, Gaur Yamuna City — a different sector and a different unit type from either Chrysalis or Plume, also pre-RERA and EOI-only at this stage. See current status at Gaurs Studio Bento. Separately, Eldeco Echoes of Eden, Ballads of Bliss and Whispers of Wonder were long assumed to be one project under different campaign names — but UP-RERA records show three separate registrations by the same developer on adjacent Sector 22D plots: EOE (UPRERAPRJ125342/02/2026), Ballads of Bliss (UPRERAPRJ921261/05/2025) and Whispers of Wonder (UPRERAPRJ752382/09/2025). Verify each independently before booking. Full walkthrough in our Ballads of Bliss / WOW disambiguation.
How to verify any row yourself
For any RERA number on this page, search it directly at up-rera.in rather than trusting a portal listing or a broker's claim — that includes the nine rows we've tagged “Confirmed” or “Reported” above, since portal data can lag or misstate a live filing. For current pricing on any project, ask for the RERA-filed cost sheet, not a WhatsApp-forwarded price list. And for County and Orion, treat the absence of a verifiable RERA number as the finding itself, not as an invitation to fill it in with a guess — ATS Allure's number is now confirmed (see our full review), but its other figures still need the same caution.
