Inside Plan D
Three bedrooms upstairs — plus a real home office downstairs.
Plan D is built around one thing most townhomes can't deliver: a quiet, doored ground-floor flex room separate from the bedrooms and main living level. Most buyers use it as a dedicated home office — far enough from the kitchen for real video calls, close enough to step away between meetings. It also works as a gym, guest suite, playroom or studio as your life changes.
Up one level, the open kitchen, dining and living area opens to a balcony – quartz counters, oak cabinetry, complete appliance package, and a powder room. Up another, three full bedrooms and 2.5 bathrooms, with the primary stretching the width of the home and its own ensuite and walk-in closet. Above it all, your private 675 sq ft rooftop patio – the largest at Addition – with gas BBQ hookup.
