Three components.
One complete system.

Engineered, factory-made, and validated against Indian IS codes — the IHS-One system replaces the slow, wasteful steps of in-situ construction with parts that fit together precisely.

How it assembles

A short animation of the Nutan walling and Prabal roofing system going up — interlocking bricks, precast joists, and planks forming a complete, monolithic structure.

Nutan interlocking bricks

Mortarless · Self-aligning · 3.5× a red brick

Interlocking bricks — hence faster and more accurate. Nutan bricks interlock vertically and horizontally, with no mortar joints and no plastering. Wastage is negligible, and full and half bricks give clean corners and junctions.

Prabal RC joists

Precast · Reinforced · Spans up to 5 m

Factory-cast reinforced concrete joists are placed across walls on bed blocks, then carry the planks above. They replace conventional shuttering and the long curing wait of in-situ slabs.

Prabal RC planks

Composite roof & floor slab

Planks rest across the joists and are aligned, then topped with a haunch fill, steel binding and a ferrocement course to form a monolithic composite slab — a complete roof in days, with up to 200% faster roofing.
