Introducing the Magellan Series

Are you a City of Seattle resident? If so, check out this website – ADUniverse. It contains a lot of great information regarding backyard cottages, which are known legally as Detatched Accessory Dwelling Units (DADUs). Seattle has pre-approved 10 cottage designs for fast-tracked approval and construction. 

When you browse the pre-approved plans, be sure to check out the MADADU from Magellan Architects. Carriage Houses NW is excited to announce that Magellan has chosen us as their preferred builder for this beautiful cottage! They have also designed other backyard cottages and tiny houses on wheels, exclusively for CHNW and our customers. You can find those designs on our website’s Magellan Series.

The Rio


Esteemed architect Pedro Castro designed this beautiful tiny house on wheels. The exterior boasts a mix of wood & metal accentuated by classic black windows, including a massive end-wall window that seamlessly connects the interior space to the beautiful outdoors. The interior is highlighted by custom Euro-cabinets generously included in the living area, kitchen, under the stairs and in the loft. This tiny house features all the creature comforts: a full appliance package including fridge, oven/range, dishwasher, a combination washer/dryer, mini-split heat/air conditioning and on-demand hot water. The stair landing affords the space to fully stand while in the loft area, while still offering approximately 60 sq ft of usable loft space in addition to a full wall of cabinets/closet space.

No detail has been overlooked in creating a space that is visually stunning and fully livable.
