Acreage and land

I grew up in the Okanagan. Today I list building lots at Tyndall Bench, acreage on Oyama Road and Middle Bench Road, and homes from Winfield to Oyama. If you are buying land, I can tell you what it takes to service a lot and build on it here.

Tyndall Bench is the Hall Cassie Marshall Group's lakeview community above Okanagan Lake, next to Lakestone, with 26 homesites in phase 1. Tyndall Bench at HCM
