The Galway master plan is expected to take decades to develop, but the first phase is 114 acres.
Lots currently for sale start at $138,000 and go up to $153,000 before taxes.
Show homes from select builders have been set up in the far west-end development.
The first-stage plans include a street of attached bungalows, targeting a 55-plus demographic. The plans also include three-level townhouses.
Housing is also mixed with green space and some commercial properties.
“The opening of our information centre and first model home marks an exciting milestone for Galway, as we can finally welcome the visiting public to see our vision for this community realized,” Williams said.
“We have spent the past couple of years preparing the land, building the infrastructure and carefully planning to ensure that Galway is a preferred location for future residents. Nestled within generous green space and beautiful trails, you will find beautiful modern homes with a real attention to detail. We are so delighted to finally be open for business.
“Since 2011, we have invested over $100 million on Phase One alone, creating hundreds of jobs and massive economic activity in the region... I am particularly proud today to see a photo hanging in the information centre of the Galway Family – my mother’s family and the namesake of this great development.”
Galway's master plan is 2,400 acres.
The ceremony also included commanding office Lt.-Col. Paul Furlong and Sgt.-Maj. Major Nolan Will from the Royal Newfoundland Regiment to unveil Beaumont Hamel Way, a main thoroughfare within the Galway development.
