News: Edifice to Dismantle Tilted SNN Raj Etternia Tower-24-07-2026

Edifice Engineering, the firm behind the controlled demolition of the Supertech Twin Towers in Noida, will bring down the 18-storey residential tower at SNN Raj Etternia in Bengaluru that the developer has decided on its own to raze and rebuild after it developed a tilt.

Anuj Sanjay Jain, Director of Operations, SNN Raj Corp, told Hindustan Times Real Estate that demolition should take five to six months and reconstruction around 18 months. The rebuilding, estimated at around Rs 20 crore, will be funded internally with no financial burden on customers. Diamond wire rope cutting, a controlled dismantling technique, will be used to limit vibrations and protect neighbouring towers.

All 49 affected buyers will be paid during the reconstruction period to help cover EMIs and rent, with the amount linked to apartment size, Jain said.

The project

SNN Raj Etternia, near Kudlu off Hosur Road in South Bengaluru, has 972 apartments in around 15 towers. Of these, 822 have been handed over and 150, including the 49 in Block E-3, are yet to be delivered. Each apartment has an average ticket size of about Rs 1.5 crore. Construction of the block began in 2022.

Jain said detailed investigations of the other towers gave consistent readings and the problem is confined to this block because two boreholes contained incorrect soil data. The company has informed the Karnataka Real Estate Regulatory Authority (RERA). Since the project already has an Occupancy Certificate, he said, RERA has no provision for extending the completion timeline, making the situation unprecedented.

How it was found

According to Jain, the company had received the OC and begun showing apartments when final quality checks revealed unusual undulations along the driveway, with the slope reversed in places. Structural engineers were called in, and a fresh geotechnical investigation showed a complete mismatch with the original soil report.

The tilt cannot be seen with the naked eye. Differential settlement has caused a deviation of around 200 mm in a 60-metre-high tower, detectable only with specialised instruments. Consultants suggested stabilising the structure through micro-piling, but the company rejected this because problems could still arise 10 to 15 years later.

Jain said buyers were shocked at first but backed the decision once the reasons were explained. Ashok Patel, an affected buyer, said he was disappointed initially but relieved after understanding the developer’s intention, and noted that he had inspected his apartment and found no defects.

Earlier demolitions

The Supertech towers were razed in 2022 on a Supreme Court order for violating building regulations, and the Maradu complexes in Kochi in 2020 for breaching Coastal Regulation Zone (CRZ) norms. At Chintels Paradiso in Gurugram, multiple towers were declared unsafe after a partial collapse in 2022. The Bengaluru tower, by contrast, is being pulled down voluntarily before possession.
