Ronayne companies has constructed office buildings for a variety of customers since the 1940's and Ronayne Construction continue this practice today.

At present technology and new business practices are driving significant change to customers requirements of office buildings. The traditional multilevel office buildings to accommodate the structured administration of large public and private organisations is giving way to the requirements of flatter organisations which require less space. The office buildings of today tend to be of more specific design, to address the needs of specific customer operations. The interiors have become more important than the exteriors.

Ronayne Construction provides office buildings for customers on a variety of different formats. The increase in customer specific requirements in office buildings is increasing specialisation among designers who are customer specific rather than market segment specific. In this environment Ronayne Construction is increasingly constructing office buildings designed by the customer's designers, rather than on a design and build basis.
