Commercial Building

We carry out a large variety of commercial works, from minor alterations to 'design and build' contracts.


We service a regular client base within various industries. Industrial businesses need a reliable contractor to carry out work in their environment to their required standards. We are a contractor who complies with the health and safety requirements of the Employment Acts and who completes projects on time and on budget. This is why we are a regular contractor with organizations such as Fonterra's Edendale plant and Alliance Group's Mataura plant.


We carry out all sorts of residential work, from fitting a new door lock to building million dollar plus designer homes. The same care and attention is applied to the job no matter how large or small.


We have extensive experience within the dairy industry, having completed a large number of dairy sheds: herring bone, rotary and robotic throughout Southland and West Otago.

Sheds Southland

We can design and build custom or kitset sheds of all sizes whether that be on the farm or in town. Given your requirements, we can arrange design and lodge building consents, program and execute construction. We carry out a wide range of farm maintenance and have our own lifting and access equipment to ensure the job is done safely


We are regularly called upon to complete insurance works for various insurance companies and are an accredited supplier to Vero Insurance.
