About Us

CPT Interiors & Constructions Pty Ltd, is a family owned and operated company and has been operating since 1989. Directors Sean O’Sullivan and Bernard O’Sullivan have over 60 years experience between them in the building industry.

We are committed to providing quality workmanship on all projects undertaken and specialise in Commercial and Residential Designed Projects. CPT offers the choice of fixed price contracts or cost plus contracts, on time completion and we guarantee all our work.

Our continuing success is attributed to our professionalism, ‘on time’ completion using only specialist tradespeople, attention to detail and a proven past record of successful delivery of all projects. Our approach and services remains focussed on our clients. All works are strictly supervised by ourselves in conjunction with our specialised Site Foremen.


We have a very experienced team of employees who have worked for CPT and in the building industry for a substantial period of time. Their experience, commitment and attention to detail, is one of the reasons that CPT has an outstanding record in completing projects with exceptional detail and on time.


We carry all insurances namely Contract Works Insurance, Public Liability and Workers Compensation.
