The Heartwood Residence sits on the east bank of the Willamette River in Portland’s Oak Grove neighborhood. Offering a sweeping panorama of the river and its wildlife, the home overlooks boat docks, freight barges, and an early 20th-century railroad bridge, recalling the city’s industrial roots. A single-level compound oriented around a large maple tree preexisting on the site, Heartwood continuously opens up from the courtyard to the river. The home’s main entrance fronts the river, allowing for arrival by boat.
