About Roundtower

In 1998 Richard Good-Stephenson returned to West Cork to restore Cor Castle his family’s ancestral home which was at that time a roofless ruin. The team he assembled for the project decided to produce the lime mortars and plasters required on site in Innishannon.

Shortly after they started producing the various lime products needed it became obvious that others in the area also required these products and a decision was made to set up a business to satisfy this market, which lead to the birth of Roundtower Lime.

The family moved back into Cor Castle in 2001 by which time Roundtower Lime had become an established entity within the Lochplace group of companies. In the subsequent years Roundtower has grown significantly and now supplies lime throughout Ireland and the UK and internationally including Australia, New Zealand, United States and China.

Harry Good-Stephenson joined Lochplace in 2019 and took over the day to day running of Roundtower in 2020 when it was decided to transfer the Roundtower operation out of the Lochplace group and into a new company called Roundtower Building Products Ltd.

Building on two decades of experience in the lime business Roundtower Building Products has gone on to become a market leader in the supply of sustainable, environmentally friendly building materials and systems, providing a ‘one-stop’ shop to customers through Ireland and the U.K. We engage with all areas of the market from builders merchants and other lime suppliers through to architects, tradesmen and home owners.
