What to Check in the Sobha Sienna Specification Sheet?
A few lines carry the most day-to-day impact, so read them closely.
Sobha Sienna construction quality
Sobha Limited was founded in 1995 by P.N.C. Menon. It was known as Sobha Developers Limited until 2014 and now has a presence in more than 10 Indian cities.
Its name rests on a quality-first, backward-integrated model. Key building components are produced by the company itself, so standards stay consistent from one home to the next.
- In-house interiors: Sobha handles interiors itself, which keeps finishing work consistent across homes.
- Glazing and metal works: The company produces its own glazing and metal works for windows and metal elements.
- Concrete products: Sobha manufactures its own concrete products, so it controls the materials behind each building.
- Quality control under one roof: Keeping each stage in-house gives close control over finishes and workmanship, from design to handover.
For a buyer, this matters because the finish you see on handover reflects decisions made long before the apartment is built. This makes Sobha Sienna a dependable choice for buyers who value a consistent finish.
Sobha Sienna on the OMR corridor
Sobha entered the Chennai market in 2012 with Sobha Meritta at Kelambakkam on OMR, followed by Sobha Serene.
Sobha Sienna Egattur carries the same quality-first approach. It sits on the OMR corridor between Navalur and Kelambakkam, about 2 km from SIPCOT and the Siruseri IT Park.
Checks before you book
- Brand names: A sheet that names the make of each fitting gives the clearest picture of your finish.
- Electrical load and power backup: The sanctioned load and backup per apartment show how comfortably your home runs.
- Water supply and treatment: On the OMR corridor, the supply arrangement and treatment provision matter for daily comfort.
- Lifts per tower: On a B+G+32 tower, lift provision shapes the daily experience for 650 households.
- Included fittings and provisions: “Provision for” means a point is ready for the appliance or fitting you choose, so ask which items are included and which are only provisions.
Registration with TNRERA is coming soon. Once it is issued, confirm the registration number, the specifications attached to the agreement for sale and the exact configuration and floor of your unit.
Read the sheet together with the floor plan for your 3 BHK or 4 BHK home, so that every room and fitting is clear before you book.
Check the total cost as well. Prices exclude GST, registration, stamp duty, maintenance and other statutory charges.
See the floor plans, price, master plan, location and amenities pages for the rest of the project picture.
