Overview

Description

Each side features 3 bedrooms, 2.5 bathrooms, and a 2-car garage, with approximately 1,650 sq ft per unit of thoughtfully designed living space. Inside, you'll find open-concept layouts, high ceilings, abundant natural light, quartz countertops, stainless appliances, and sleek contemporary finishes that rival luxury downtown condos--without the limitations.
