About Us

Olsen Construction is based on Sydney’s North Shore.

We have a wealth of experience in all aspects of residential construction.

Primarily, we focus on residential renovations, extensions, and additions, and custom new builds.

With over 35 years in the industry, we bring a wealth of skills and knowledge to every project.

Our experience covers a range of residential construction tasks.

Our Expertise

Drawing on decades of experience, we're committed to turning your vision into reality.

Whether you’re looking to accommodate a growing family, or looking to maximise the value of your home, we can help.

Our Service Area

The majority of our construction projects have been on Sydney’s North Shore, both the Upper North Shore, and Lower North Shore.

While the North Shore remains our central focus, we’re always open to working with clients in surrounding areas.

We have undertaken projects in The Northern Beaches, The Inner West, The Hills District, and The Eastern Suburbs.

If you’re interested in our Design Services, we are less limited geographically, and can work with you in any part of the world, provided we can get to you.

Our Team

Olsen Construction is a family business.

Our Process

Our team stays onsite for the whole duration of the build.

While many of the other players in the industry use contractors for the entirety of their projects, we employ our core team.

We have worked with many of our contractors and suppliers for many years. Building trusted relationships with these people and companies allows us to maintain the highest quality.
