Can the World's Tallest Skyscraper Also Be Smart? Ernest Flagg Thought So

In 1908, the skyline of New York City was forever changed by the arrival of the Singer Building — a towering symbol of architectural ambition and technological progress. At the time, it claimed the title of the tallest skyscraper in the world, but its significance extended far beyond its impressive height.

What truly set the Singer Building apart was its integration of advanced environmental controls, a concept well ahead of its time. Johnson Controls introduced a sophisticated system that allowed for precise regulation of indoor temperatures across multiple floors, demonstrating that buildings could do more than stand tall — they could think smart.

This early example of intelligent infrastructure laid the groundwork for the smart buildings we see today across the United Kingdom. From commercial offices in London to healthcare facilities in Manchester, Johnson Controls continues to lead the way in creating responsive, energy-efficient environments that prioritise comfort, safety and sustainability.

In 1908, the Singer Building rose above New York as the world’s tallest skyscraper – and one of the smartest. With its 1,200 thermostats and 1,800 valves, the pioneering temperature system installed by Johnson Controls set a groundbreaking new standard for intelligent, responsive architecture.

A Visionary Architect Meets a Global Brand

At the turn of the 20th century, architect Ernest Flagg was redefining the skyline. Commissioned by Frederick Gilbert Bourne of the Singer Sewing Machine Company, Flagg envisioned more than a towering headquarters. He imagined a building that combined elegance with efficiency — one that could think for itself.

Johnson Controls delivered on that vision with the Johnson System of Automatic Temperature Regulation. Featuring 1,200 thermostats and 1,800 valves, the Singer Building offered precision climate control across 47 storeys — a feat unmatched at the time.

Smart Buildings Begin Here

Flagg’s philosophy of blending form, function and foresight mirrors Johnson Controls' commitment to smart, sustainable buildings. For over 140 years, we’ve helped transform structures into responsive environments that optimise energy, improve safety and enhance comfort.

Though the Singer Building no longer stands, its legacy lives on in today’s intelligent towers. From London to Leeds, smart buildings are shaping the future of urban design — and Johnson Controls is proud to lead the way.

As we celebrate our 140th anniversary, we honour visionaries like Ernest Flagg who innovated both buildings and the future.
