A historic houseboat in Seattle’s Madison Park neighborhood is getting new life thanks to a 3-year renovation project from local firm Best Practice.

The firm’s effort expanded the houseboat’s original 1,200-square-foot footprint with an 800-square-foot black metal facade addition that will help an area couple find a more comfortable fit for their growing young family.

Per the architect: “This residence began its life as a floating home on Lake Union! It was transported and firmly affixed to the ground near the shore of Lake Washington, but we still like to think of it as a Boathouse. With a charming street presence, the design team crafted an open interior space with vaulted ceilings, new basement living spaces and a primary suite upstairs in the new addition.”

Best practice turned the existing bedroom into a whimsical space for the couple’s daughter. An open floor plan replaces the clutter of the previous layout and features a vaulted stained cedar ceiling added home office and laundry space. The new upstairs is composed primarily of the master bedroom suite. 

The firm worked hard to ensure its renovation honored the home’s aquatic lineage. The Seattle Times has more on houseboat communities in the city here.
