S. Ferdinand Townhomes

Broderick Architects

Posted: April 12, 2018 | Projects

The 5,335-square-foot S. Ferdinand Townhomes project involved the conceptual design, permitting, construction documentation, and administration of three new townhouses on a tight site behind two existing historic residences within the Columbia City Historical District of Seattle, Washington. 

Each of the approximately 1744-square-foot townhouse units features an efficient floor layout, including three bedrooms, 2.5 baths and a laundry room, and is located over a private garage. 

Care was given to making the units contextual with the surrounding neighborhood while also intentionally not looking “historical.” The townhomes were also designed to not distract from the 100+-year-old homes that prominently face S. Ferdinand Street, and the designs went through extensive screening before being approved by the Landmarks Board. 

The exteriors are finished with a low-maintenance rainscreen system consisting of cement fiber panels and vertical cedar siding. Units are accessed via a shared brick paver courtyard and feature welcoming entry steps, trellises, gardens, and rooftop decks.

Inside, tall windows with transoms and slot windows bring light deep into the units. The stepping and cantilevered building elements balance the need for light, variation, fire separation, and visual interest with limited space, and allow the owner/developers to achieve maximum value from their site.

Broderick Architects used their innovative Building Information Software from building concept on to working drawings and extensive site modeling that was required for the Landmarks Preservation Board presentations.
