Inside Plan B1
The efficient 3 bedroom layout – without losing the rooftop.
Plan B1 keeps everything that makes Addition feel generous – three full bedrooms, 2.5 bathrooms, a side-by-side double garage, air conditioning and a 600 sq ft rooftop patio – in a tighter 1,417 sq ft footprint. The main living level is open-concept with quartz counters, oak cabinetry and a complete appliance package, leading out to a balcony off the dining area.
Upstairs the primary bedroom has a private ensuite and walk-in closet, with two more bedrooms and a shared bathroom alongside. Up top, your own outdoor room: gas BBQ hookup, space for a dining table and lounge furniture, and open sky.
