Here is how each of the four stacks up once you strip the numbers down to size and rate per sq ft, rather than just the headline price on a brochure.
Prestige Royale Gardens Holds the Same Rate Across Both Its Sizes
Prestige Royale Gardens sells its 1 BHK in two sizes, a 602 sq ft unit from Rs. 73.44 lakh and a 697 sq ft unit from Rs. 85.03 lakh, and both work out to almost exactly Rs. 12,200 per sq ft. That kind of flat pricing across sizes is rare on this belt, where a bigger unit usually carries a hidden premium once you do the math. The project sits on Doddaballapur Road in Yelahanka, about 9 km from Bettenahalli, and has stood ready since July 2020, so what you are buying into is a proven, lived-in address rather than a promise on paper.
Prestige Finsbury Park Hyde Gives You the Lowest Entry Rate
Prestige Finsbury Park Hyde comes in cheapest per sq ft among the four, though only on resale now, since the builder has sold out every unit here. Current listings of 646 to 750 sq ft trade close to Rs. 75 lakh, working out to roughly Rs. 10,000 to Rs. 11,600 per sq ft. It sits on Bagalur Road in Aerospace Park, about 6 km from Bettenahalli, and finished construction back in 2023. That lower rate is less a bargain than a sign the project has not climbed as fast on resale as the bigger 2 BHK and 3 BHK stock inside the same address.
Prestige Gardenia Estates Sits at the Top of the Band, but RERA Is Already Sorted
Prestige Gardenia Estates prices its 1 BHK from about Rs. 80 lakh for a 650 sq ft unit, close to Rs. 12,300 per sq ft, which puts it right at the ceiling of this narrow price band. About 10 km away in Yelahanka, the 12-acre township will eventually hold 2,613 flats across 19 towers once construction wraps up. It launched in December 2024 and already carries full RERA clearance, even though possession is not due until December 2029, so you pay close to the belt's top rate for a brand-new layout with the paperwork already behind it.
Prestige Parklane Could Undercut Every Rate Here, If the Numbers Hold
Prestige Parklane has not launched yet, so treat every figure tied to it as an early estimate rather than a locked-in rate. Indicative pricing places its 550 to 650 sq ft 1 BHK between Rs. 57.8 lakh and Rs. 78 lakh, which lands around Rs. 10,500 to Rs. 12,000 per sq ft, roughly in line with the other three projects here. It sits inside KIADB Aerospace Park in Devanahalli, and no RERA filing exists yet since environmental clearance only cleared its early review stage in August 2026. Wait for an official price sheet and a real RERA number before you take any of these numbers as final.
