Our history

From Granville sawmill to Thornton

  1. 1854

    Founded as Coates & Harper, sawmillers and timber merchants in Granville.

  2. 1858

    Expanded with a branch on George Street, Parramatta.

  3. 1912

    The business became L. Harper & Co.

  4. 1918

    Operations moved to Morton Street beside the Parramatta River, using river transport to bring timber in. Through the 1920s the company grew into a major Sydney timber supplier during an era of industrial expansion.

  5. 1930s–40s

    Under R.L. Harper the company weathered the Great Depression and was renamed Harper Timber Co. Pty. Ltd. During World War II its facilities were commandeered for military use.

  6. 1962

    Urban development pressures prompted the move to Wentworth Avenue, Pendle Hill, home to the business for more than five decades. Neil Harper managed the business until 1988.

  7. 2007

    Merged with Chadwicks Timber.

  8. 2015

    Acquired by the Johnson Bros. Group, with operations that now include facilities in Thornton and Mona Vale and services well beyond timber.
