Tiger Trailers is to build a £22m factory at a new site in Winsford, Cheshire, four times the size of its current facility nearby.
The building will sit on a 20-acre plot of land and include multiple production lines, a dedicated trailer showroom, weighbridge, customer meeting facilities and parking for 350 cars as well as trailer parking.
It will house a fully equipped training school to help develop apprentices, and double Tiger's painting capacity.
Tiger will also introduce a more efficient flow for moving materials into and around the factory.
The firm has manufactured 2,500 trailers since being founded three years ago, currently employs more than 200 staff and has the capacity to manufacture about 35 products a week in its existing factory, which is on five acres of land.
Expansion at the site will take place in two phases - an initial £14m investment will see the company will break ground on the new site in early 2018, with production to transfer into the new 125,000ft² factory later in the year.
Nearly 300 people will then work at the site which will allow production capacity to rise to about 65 units a week. The company will also install its first moving production line.
Phase two, which will be timed to meet business demand, will add another 100,000ft² of manufacturing capacity and take the workforce up to 500, with production capacity at 120 trailers a week.
Joint MD John Cartwright said the investment continues Tiger's ethos of keeping the entire manufacturing process under one roof.
He explained: "For Tiger to achieve what it has in such a short space of time is incredible and testament to every member of the team's hard work and commitment.
"The current factory, although one of the most modern in Europe, was adapted to suit our requirements.
"The ability to design and build a new factory from the ground up will be hugely advantageous for us, providing a platform for growth and the next phase of the Tiger Trailers story."
Joint MD Steven Cartwight added: "From a design perspective, the new factory will be as innovative and well-engineered as our trailers and bodies. We want to offer the best working environment and facilities for our growing team, plus provide a first-class experience for visiting customers.
"We're going to make our new home a true flagship for UK manufacturing."
