Featherweight Engineering
Zero Foundation Stress
Ultra-Lightweight
LGSF structures weigh approximately 1/3rd of a traditional brick-and-mortar floor. This means you can safely add a floor even if your old concrete foundation wasn't originally designed for it.
Live-In Construction
No messy wet cement, no endless debris. Because LGSF is a 'dry build' process, your family or tenants living on the floor below will experience zero disruption during the installation.
Weather & Seismic Proof
The high-tensile steel frame is anchored directly into your existing RCC columns using heavy-duty chemical fasteners, making the new roof extension highly resistant to earthquakes and extreme winds.
The Penthouse Experience
Sky-High Luxury
A rooftop extension shouldn't look like an afterthought or a temporary shed. With LGSF, we create high-end architectural penthouses that blend seamlessly with your existing building's facade.
Our precision engineering allows for massive floor-to-ceiling glass windows, wide open terraces, and premium drywall finishes that make the interior feel like a 5-star suite.
- Supports Premium ACP & Stone Cladding
- Perfect Acoustic & Thermal Insulation
- Concealed Wiring & Plumbing Channels

Flawless Integration
Adding a floor to an existing structure requires precision. Our structural engineers conduct a thorough audit of your current roof and RCC columns. The LGSF chassis is then custom-designed in 3D to distribute the new load perfectly.
The steel frames are hoisted via crane and chemically anchored to the existing roof slab, ensuring a completely leak-proof and structurally integrated expansion.
