Our Story

Greensted, a small village in England, is home to one of the oldest wooden churches in the world. Still in use today, the original nave was constructed during the middle ages. Made of timber and oak, this building has endured the tests of time.

We chose our name to honour the tradition, nature and workmanship that has kept this historical building standing for all of these years.


years of experience


Red Seal Certifications


commitment to sustainability

Mike has spent most of his life on some form of construction site – starting in residential, then branching out to commercial and industrial environments. He spent 5 years working as the Procurement and Logistics Manager for a large industrial construction company allowing him to further develop his management skills and earn his Red Seal as a Parts Technician. During this time he realized his passion fell into sustainable development of residential construction, so he returned to his roots in 2016 and has since managed the construction of over 50 homes on Vancouver Island.

Mike Chiorando

Co-Owner/Project Manager

Cory grew up in Nanaimo, enjoying the great outdoors and playing competitive hockey. He began his carpentry apprenticeship in 2009, and has been working in the industry ever since. He has a keen sense for detail, and believes time and craftsmenship should be invested into every project. In 2016, Cory began his own small construction business so he could focus on improving sustainability and environmental awareness on every jobsite.

Cory Russell

Co-Owner/Site Supervisor

“We are building a new carriage home and have had the privilege of working with Mike, Cory, and their team from Greensted Construction Inc.  

From the initial consultation to the near completion of our project we have had great open communication.  All of our questions or concerns have been immediately addressed through the process.  

Mike & Cory do quality work and we have been very pleased with the finished product.  They have been happy to see our ideas through, as well as, give us helpful suggestions when changes were needed.

Thanks Greensted Construction for being a part of making our little dream come true!”
