About  Us

Bildspec was established in 1969 by Sydney engineer, John Ellacott. The business started off as the NSW distributor of an overseas company’s range of folding doors and operable walls. When the overseas company went out of business in the mid 1980’s, Bildspec started manufacturing our own range of operable walls from high-quality, locally sourced parts. At the same time, the business moved from its original Redfern Location to a manufacturing facility in Marrickville.


Bildspec quickly developed a reputation for providing industry-leading products within fast lead times, and at great value to customers. This value does not only encompass price, but also product quality, speed to market and the overall level of customer service offered. In 2019, John Ellacott retired and the Bildspec business was sold to The Kaplan Door Group, owners of The Australian Trellis Door Company. In 2020 Bildspec commenced the supply and installation of our products in Victoria and Queensland. 


After significant continued growth the company moved its manufacturing operations from Marrickville to a purpose built factory at Regents Park NSW.

Our commitment is to supply high-quality operable walls at competitive prices, as well as to provide innovative solutions and uncompromising after-sales service.
