Amberstone Vectra at Chambenahalli: Homes, RERA Details and Pre-Booking Checks
Chambenahalli, a village at the far end of the Sarjapura Road corridor in the east of the city, is where Amberstone Ventures has launched Amberstone Vectra. Handover is set for July 2032, so this is a purchase for people who can plan far ahead. The sections below describe the registration, the towers and their floor plans, the money involved, the group behind the project and the paperwork to complete before paying.
What the Registration Says
Karnataka RERA issued registration number PRM/KA/RERA/1251/308/PR/230726/008835 on 23 July 2026. On 10 July, ahead of that, the Anekal Planning Authority cleared the building plan. Anyone can look up the promoter and its quarterly progress filings on the state RERA portal.
Construction is scheduled from 1 September 2026 until 31 July 2032, which means the project is at its very first stage. A buyer who books now is paying for a home almost six years away. The agreement of sale should repeat the registered handover date, and its clause on interest for delay deserves a slow read.
Layout of the Site
The registration covers 306 apartments split between two towers, and each storey has six homes. The land is 30.11 guntas over and above 3 acres, equal to 15,245 sq m or about 3.8 acres. Two of every three homes have three bedrooms, and the other third have two.
Block A climbs 26 storeys to 83 m, with 156 homes. Block B has 25 storeys and 150 homes. Both stand above two basement levels, and the buildings occupy about 12% of the plot, so most of the ground stays free for roads, planting and amenities.
The site is described in the registration as survey numbers 134/2, 134/3, 133/2 and 133/3 at Chambenahalli, in the Sarjapura Hobli division of Anekal Taluk, pin code 562125. Plans provide 301 covered parking slots and 36 open ones.
Sizes and How to Compare Them
The 102 two-bedroom apartments have carpet areas of between 683 sq ft and 726 sq ft. The 204 three-bedroom homes come in two bands. One is roughly 910 to 918 sq ft, and the bigger band starts close to 1,040 sq ft and tops out at 1,062 sq ft.
Carpet area counts only the usable space within an apartment's walls, and the agreement must state it. Brochures lean on saleable area, which adds wall thickness, balconies and a portion of shared spaces. When two projects are compared, the rate per unit of carpet area is the fairer yardstick.
Getting There
An existing 12 m road runs along the site's eastern side. Local roads connect it to Sarjapura Road, the main artery that leads to Carmelaram, the ring road and the Bellandur offices. Dommasandra is the nearest known town, and the plot is at the outer limit of the corridor.
Namma Metro Phase 3A includes a planned line along Sarjapura Road. Until it is built, the commute is by road, so try the peak-hour drive in both directions before deciding. The Sarjapura Road page covers the corridor, schools and office hubs.
Fit and Timing
Vectra is aimed at buyers looking for a two-bedroom or a compact three-bedroom home on this side of the corridor and are happy to wait. With six homes per storey, corridors are short and the load on each lift is moderate for towers this tall. It also helps people who like the area yet find larger homes stretch the budget.
Households that must relocate in two or three years should look at ready projects instead. The same holds for anyone who wants a main-road address, because the village is an interior one served by local roads.
The Real Cost
Begin by asking for the present price list unit by unit, together with the floor-rise charge and the schedule of payments. The base price is just one component. The cost sheet for a chosen apartment should break out:
- The rate and the area on which it is charged
- Premiums for floor height and facing
- How many parking slots the price covers
- The club joining fee and the maintenance corpus
- Power, water and sewage connection fees
- GST of 5%, applicable to a home under construction
- 5% stamp duty with cess and surcharge (5.6% combined), plus 2% registration
Any scheme offered at launch, a deferred EMI plan for instance, must go into the agreement along with its cost and expiry. Feed the final price into the EMI calculator to see the monthly instalment.
About the Group
The project belongs to the group of Amberstone Properties, which has built mostly in JP Nagar. In the same village the group is putting up Amberstone Ventara, four towers with a mix of 3 and 4 BHK homes. Visiting that site gives a sense of the construction pace and quality next door.
Paperwork for a 2032 Handover
A launch so far from completion requires thorough documents. Work through these steps first:
- Compare the RERA number, promoter and completion date with the portal entry.
- Ask for the carpet area, balcony area and land share of the unit on paper.
- Check the approved plan for storeys, tower positions and amenities.
- Let a lawyer examine the title papers for the survey numbers, plus an up-to-date encumbrance certificate.
- Study the delay interest and refund clauses of the draft agreement.
- Link every instalment to a certified construction milestone.
- Visit the site, and take the approach road at the evening peak.
The developer can share current rates and the units still open in every tower. Further options nearby are in our Sarjapura Road apartment listings.
