About

We are a Construction company based in the Eastern Suburbs with over 35 years experience, with our work taking us all over Sydney.  We pride ourselves on the quality of our work, excellent craftsmanship and satisfied clients.

C O’Brien Constructions has earned it’s reputation by having a professional approach and we thrive on finishing jobs on schedule or well before it.

We cover all domestic and commercial work and no matter what size your job is, we will do it – from building a new house down to a simple deck or pergola.  We have worked in a lot of tight sites in Sydney’s inner city, where there was no space for storage, parking, skips and had to deal a lot with our friend’s, the council rangers.

We have done numerous shop fit-outs, office fit-outs, hoardings and major structural changes to existing buildings.

We have converted dusty attics into amazing bedrooms or office spaces with a proper stairs installed, where our clients never could have imagined.

We also work on a lot of first floor additions to existing homes and knock out ground floor walls to make open plan living areas.
