About Us

Providing top quality quarry materials for more than a century

Family business Hillhouse Group is one of the largest suppliers of quarry materials in Scotland.


Established in 1907 at Hillhouse Quarry near Troon, the company prides itself in its high quality products and consistently reliable service.


This commitment to excellence – and more than 112 years of continual investment in plant, equipment and people – are the foundations of Hillhouse Group’s success. Today the company employs more than 200 dedicated staff members across its six sites spanning Central and Southwest Scotland.

Materials and expertise

The sites supply asphalt, aggregates, ready mixed concrete, concrete products and recycled materials. What’s more, Hillhouse Group also provides road surfacing, highway maintenance, civil engineering and operated plant hire services.


This diverse range of products and services, high capacity capabilities and geographical reach make Hillhouse Group the supplier of choice for public and private sector customers alike.


The company has played a key role in a number of major infrastructure projects while continuing to meet the needs of its longstanding customer base. For example, Hillhouse Group was chosen as the sole supplier of asphalt and bituminous products to the M8, M73, M74 Motorway Improvement Project – a high-profile, large-scale project requiring huge capacity and the ability to meet complex logistical demands without compromise.

Our Commitment

As a family business we take huge pride in our local communities and our people. 


We are committed to taking responsibility for giving something back to the communities in which we are based, and proudly support an array of local causes and charities.  


Hillhouse Group continually strives to be at the forefront of best practice when it comes to employee welfare.
