Engineered Models
Three models, built for Indian conditions.
We don't sell off-the-shelf shelters. Each of these three models is a starting point we adapt to your site, soil, and family. Final specifications are confirmed during your consultation.

Confidentiality note: For the safety of our clients, we do not publish full technical specifications. Exact structural calculations, soil-specific adaptations, and systems configurations are shared under NDA during your confidential consultation.
What We Do
What we do, in three parts.
01
Underground Shelters
Full bunkers and concealed safe rooms. Engineered for your soil, water table, and property. Built to keep a family safe and comfortable for weeks or months, not just hours.
02
Air, Power & Life Support
The systems that keep a shelter liveable: CBRN air filtration, clean water, off-grid power, waste management, communications. We install them as one integrated set, not bolted-on parts.
03
Private Consulting
Before we build anything, we understand the site, the family, and what you’re actually trying to protect against. We work quietly, alongside your architect and contractor.
Why Jaytra
The decision, in four points.
01 — Who We Are
India’s engineering-first bunker company.
Not a reseller. Not a prepper brand. A small engineering team led by a structural fabricator with over ten years of hands-on experience, focused on one thing: building civilian shelters that actually work when needed.
02 — What We Build
Underground bunkers, safe rooms, CBRN shelters.
Three models to start from — TITAN, STRATA, SENTINEL — each adapted to your site. Structural design, air filtration, blast protection, off-grid power, and communications, all built as one connected system.
03 — Who We Build For
Families, architects, and Family Offices.
We work by referral and private appointment. Our clients are private homeowners, family offices, and estate architects working on large properties across Delhi NCR, Mumbai, Bangalore, and select hill stations.
04 — Why It Matters
India has almost no civilian shelter infrastructure.
Switzerland, Israel, and Japan run national civil defence shelter programmes. India doesn’t. The private shelter you build now is generational infrastructure — designed to last 25+ years, regardless of what the next decades bring.
How We Build
Three core disciplines,
integrated into every shelter.
A shelter isn’t one thing — it’s many systems working together. Below are the three we focus on most: structure, air, and power. Two more — blast protection and communications — are covered on our Engineering page.
Structural Shell
High-grade steel with lattice reinforcement. Every calculation redone for your soil, water table, and seismic zone — no copy-paste from another project.
- FEMA 453 & TR-87 compliant
- PF 1000+ radiation shielding
- Seismic Zone II–V rated
- Corrosion, fire, waterproof
Clean Air Systems
Multi-stage filtration sourced from European and American defence suppliers. Pre-filter, HEPA 0.3 microns, activated carbon — the same equipment used in government and military shelters.
- Positive internal pressure
- Overpressure blast valves
- Manual crank backup
- Chemical agent adsorption
Power, Water & Living
Solar, generator, and battery working together. Water purified on site. Waste handled. Food storage, environmental control, and the small comforts that make weeks inside feel liveable.
- Full off-grid capability
- 100–300+ day autonomy
- EMP-shielded comms
- Environmental control

Indian Soil Engineered
Built for India
Indian soil, Indian weather,
Indian construction realities.
Most international shelter designs assume Western soil and conditions. Ours don’t. From Deccan rock to black cotton, from monsoon water tables to seismic zones, every calculation starts from where your property actually is.
4
Soil Types
Black cotton, laterite, alluvial, Deccan rock. Each one behaves differently and needs different structural calculations.
V
Seismic Zones II–V
Structural loading calculated for whichever zone your property falls in, not a generic average.
3–5m
Water Table Shift
Indian water tables move a lot between monsoon and summer. We build that shift into the base.
RCC
Indian Construction
Designed to fit with how Indian villas and estates are actually built — RCC column-beam with brick infill.
Where we work: Delhi NCR (Gurgaon, Lutyens), Mumbai, Alibaug, Lonavala, Bangalore, Hyderabad, Chennai, and select hill stations including Kasauli and Mahabaleshwar.
How We Work
From first conversation
to handover.
01 — Consultation
Private Consultation
NDA first. We spend 60 minutes understanding your family, your property, and what you’re planning around.
Week 1
02 — Site Visit
Site & Soil Assessment
We visit the property, check soil, water table, and access. Our team arrives unmarked and discreet.
Week 2–3
03 — Design
Engineering & Design
Full structural and systems design done for your site. CAD drawings your architect and contractor can work with.
Week 4–8
04 — Build
Fabrication
Shell and systems built in our controlled workshop, not on site. Welds inspected, pressure joints tested, before anything ships.
Week 8–16
05 — Install
Install & Commission
Delivery and installation coordinated with your team, arranged quietly. Every system individually tested and signed off.
Week 16–20
06 — Handover
Handover & Support
Family trained on operation. Full documentation archived. Annual checks and on-call support for the full life of the shelter.
Week 20+
Start the Conversation
Let’s have a quiet conversation
about your property.
A 60-minute private video call with our founder. NDA signed before anything is discussed. We listen, ask, and work out whether your plans and our work are a fit.
No quotes on the first call. If both sides want to take it further, a written feasibility note follows within 10 working days — at no cost, no obligation.
Direct Line
For urgent enquiries, the founder’s direct line: +91 92055 92009. Answered personally, 10:00 – 19:00 IST.
