The Rishikesh–Pauri Garhwal belt sits in Seismic Zone IV. Every villa at Willow Estates is designed to IS 1893 (earthquake-resistant design of structures) and IS 13920 (ductile detailing of RCC), with structural drawings signed by a Uttarakhand-registered structural engineer.
The build discipline
- M25 RCC framed structure, isolated column footings on natural rock strata
- Ductile detailing at all beam-column joints — closer stirrups, 135° hooks
- Shear walls at staircase cores for lateral load transfer
- Gabion + reinforced retaining walls to Zone-IV
- 1st-class brick infill, PPC cement (Ambuja / UltraTech / JK Super)
- Third-party structural audit before slab casting at every level
