ORS acquires leading commercial property advisory TWM

ORS is delighted to announce that it has acquired TWM, the Dublin-based commercial property advisory business, further strengthening its position as Ireland’s leading multidisciplinary building consultancy with sustainable growth plans across Ireland, the UK and Europe.

ORS has a proven track record of delivering innovative build solutions across various industries. It offers a comprehensive range of services that encompass civil and structural engineering, project management, infrastructure, health and safety, building surveying, assigned certifier, fire safety, environmental, sustainability and mechanical and electrical services.

TWM was founded in 2010 by Sean O’Neill and was later co-owned with Michele Jackson, who joined the business in 2014. In 2024, Willie Norse joined TWM as Managing Director, having moved from an executive role at CBRE. He leads a team of experienced, well-respected professionals with significant expertise in commercial real estate. The business currently focuses on Commercial Agency, Professional Services and Strategic Advice, with ambitious growth plans to expand into additional sectors nationwide. TWM will retain its own brand, identity, and management following the deal, within the wider ORS Group.

This acquisition, supported by ORS investment partners, Erisbeg, forms part of ORS’s ongoing growth strategy, following a number of successful integrations in recent years, including John Spain Associates, a Dublin-based Planning Consultancy, and, most recently McGovern Surveyors, a Dublin-based Building Surveying firm, which have strengthened the Group’s multidisciplinary expertise nationwide.

John Brennan, Managing Director at ORS, said “This acquisition further strengthens our ability to support clients across the full property lifecycle. By combining strategic property advisory with ORS’s multidisciplinary engineering and compliance expertise, we can offer more integrated, commercially informed support from early strategy through to delivery.”

Willie Norse said they are looking forward to leveraging the clear synergies between TWM and the ORS group of companies. “We will now be able to offer a wider suite of services to our clients and engage with more clients for our existing services.  We believe this announcement, coupled with our ambitious growth plans, will prove attractive to high-quality property professionals looking to advance their careers.”

Going forward, ORS and TWM, as part of the ORS Group, are committed to delivering high-quality services to their existing clients. This acquisition reaffirms ORS’s dedication to fostering innovation, nurturing talent, and cementing its position as a leader in the building consultancy industry.
