Located in the Arbor Lodge neighborhood of North Portland, this new addition ADU is carefully thought through.


Careful site design and the orientation of the one-story addition creates a new L-shaped wing at the north edge of the property, maximizing southern light and preserving the rear open space, yard and tree for a shared outdoors. Enhancement of these outdoor connections while maximizing privacy was crucial in this older, urban Portland neighborhood. Only a glimpse of the addition is visible from the public street.


The ADU addition houses a puppetry studio and home workshop for the owner-artist. Both are connected by a shared roof but separated by a covered breezeway. The flexible design allows for short term or long term rentals, artist space and future-proofed for a second story addition.


The modest budget allowed for an exposed concrete slab, advanced framed wall and roof, heat pump, LED lights throughout and generous windows to daylight throughout - this anchors the modern, playful and compact design. Interior and exterior transoms extend light and lend to a more expansive feel than the compact size would lead one to expect.
