About Us

Murdock Builders Merchants was originally established in 1982 with the set-up of Newry Building Supplies Ltd on the Rathfriland Road in Newry. After a brief period at this location Newry Building Supplies transferred to a bigger more central location on the Greenbank Industrial Estate in Newry where it remains today.

Murdock Builders Merchants growth has been a combination of organic and by acquisition, and we are currently recognised as a leading supplier of building materials and timber in the island of Ireland. We have 14 Builders Merchants branches plus two bespoke timber sites in Ireland consisting of Cranwood Industries and Murdock Trusses, and a Civils Division with plans for continued growth.

Cranwood Industries based in a purpose-built facility in Warrenpoint Co. Down, is one of our specialist timber sites and offers a full range of machined timber products, from standard skirting and architrave moulds to customized window boards, stair parts and door sets. With an increasing demand from both domestic and commercial customers for more intricate and detailed timber sections, Cranwood Industries has combined technical expertise with modern machining technology and imaginative designs to deliver innovative solutions in this market.

Cranwood Industries stock a large variety of high quality hardwood and softwood species imported from around the world with over 20 different species of hardwood in stock. Cranwood Industries offers customers the full range of machined timber products, for further information visit

Murdock Civils is a specialist division of Murdock Builders Merchants and was established in 2017 to give our Civils customers a focused and easily accessible location to service their requirements in a continually growing sector.

We are specialists in a range of areas including; Civils and Drainage, Geo-technical and Groundwork Engineering, Structural Waterproofing, Surface Water Management, Concrete Repair and Protection, as well as Street Furniture and Landscaping. We have developed strong working relationships with all our suppliers over many years which will enable us to carry a substantial and quality range of product to meet the requirements of our customers in a busy Civils environment. 

Murdock Builders Merchants are able to design and manufacture Roof Trusses from our Newry-based operation. Having made a significant investment in state-of-the-art plant and software we can now offer the full design and production service, complemented by an experienced Sales Team who are available to call on site to confirm measurements and discuss any queries on a face to face basis.

Roof trusses are an increasingly popular roof solution for many customers due to the reduction in labour and costs which they provide. With a specialist truss plant team in place at our Newry depot, Murdock Trusses are delighted to be able to offer customers trusses of the highest quality supported by a superb customer service. Where required, customers can be supplied with trusses which have been either treated in our on-site high or low pressure treatment facility and with Chain of Custody certification.
