A booming Bradford automotive company which moved into glitzy £2 million premises just two months ago is expanding so rapidly it has already outgrown its new home.

Maybe this has something to do with the fact that, in just a year, the firm has increased the number of countries to which it exports from seven to 45.

And the fact that having secured deals with some of the world's top car-makers, it is now an accepted international leader in the production of prestige alloy wheels.

Auto Design Technics was started by Afzal Kahn from modest premises in Thornton Road in the late 1980s. But its phenomenal growth has followed the formation of three other companies.

The original ADT carved a thriving business designing and selling head-turning wheels for discerning motorists. Its reputation grew.

In the mid-90s came Kahn Design with a mission to become the Rolls Royce of wheel-makers. It seems to have achieved that goal and sells up to 40,000 wheels a year around the globe. The aim is to triple that figure in three years.

It has earned a place of distinction in the upper echelons of high-class motoring. Its top-of-the-range 22-inch alloys will set you back a tad under five grand.

"All the wheels are designed by us," said head of sales Amjad Ali. "What we're big on and what we're proud of is that we're a British design company. All our wheels are designed in England and we manufacture in Italy.

"We're known in the business as being at the top end, with an exclusive brand. We're regarded as innovators. We're now at the stage of being a major global player."

Two pieces of evidence tend to corroborate this. Firstly, the firm's RSR wheel launched in the 80s has the distinction of being the most copied wheel in the world.

Secondly, when an Italian foundry started ripping off their designs, the Bradford firm got tough and made sure the Continental imitators were promptly shut down.

The firm has established close links with many of the world's top manufacturers such as Bentley, Aston Martin, Marcos, Jaguar and MG Rover in the UK.

Abroad, there are associations with the cream of supercar manufacturers such as Ferrari, Lamborghini, Porsche and Mercedes.

The firm is rapidly breaking into new markets every month - even the tough German scene which insists that all wheels sold are tested to destruction.

Running alongside these ventures has been another thriving niche business, V12 cars, specialising in selling the world's most prestigious and desirable vehicles.

And out of all this grew the most recent enterprise, Project Kahn, a specialised business set up to transform Range Rovers into the sort of luxury vehicle the Sultan of Brunei would deign to be seen in.

The idea is simple. Taking a standard Range Rover, Project Kahn transforms it into a distinctive rich person's recreational vehicle by adding gleaming alloy wheels, special paintwork, leather trim, lowered suspension and a DVD player in the back. The price tag? £64,000.

"We've sold 17 Range Rovers in the last nine days," said Mr Ali. "This year we've ordered 100 cars and they're selling faster than we can get hold of them."

Kahn Design launches soon in the United States and expectations are high that this will create another exponential leap in turnover.

"The Americans like the fact that we're British. Next year there's going to be massive growth for us because all the countries we have moved in to are starting to develop," he said.

Turkey and Thailand were recently added to the list. Australia and New Zealand are up and running. Brazil launches in September.

Apart from anything else, it means that the world-class wheel-makers in Canal Road are hunting for extra space.
