About us

We started in business in 1799, trading as Irvin Sellers in Liverpool, this business imported timber from North America and Scandinavia, in the early 1900's Lawrence Keizer also started a plywood importation business.

Through a series of mergers and aquisitions during the 1900's we ended up being a part of Meyer International Northern Ireland. At that time there were three companies trading in Northern Ireland, Irvin & Sellers, Keizer Venesta and JW Jacob.

In 2004, JW Jacob was sold to another company and the two Belfast Companies were bought by a local management team. In January 2007 we opened Northern Hardwood in Dungannon to supply many of our customers with hardwood products.
