BLOGGING A SEATTLE BACKYARD COTTAGE – SCHEMATIC DESIGN
a CAST architecture case study project

intro-image

We’ve completed the first round of design on our CAST architecture case study backyard cottage.

Kate and Ric’s cottage is intended to serve as an art studio, workshop and guest house. It is also designed so that it may function as a rental home if needed. Our initial round of planning looked at how the spaces might work as a rental thinking that those functional requirements would be more restrictive than the requirements for an art studio and workshop.

Elements common to all three schematic design options:

All three options place the cottage at the SW corner of the site, chosen for it’s relationship to the more public areas of the existing home and for an opportunity to create a shared outdoor room for both the cottage and the home. They all have a gable roof which was chosen for the height bonus allowed in the ordnance and to help marry the form of the cottage to the form of the existing home. All three options have the kitchen, living and bath rooms on the first floor and a bedroom loft on the second floor. Another feature common to all the options is the use of salvaged galvanized steel scaffolding components (see image below) which we plan to use as treads for ladder to the loft spaces.

SCHEMATIC DESIGN OPTION 1


This design incorporates an existing garage which more or less sits on the South and West property lines. The city land use desk (walk in) indicated that it was probable that we would be able to grandfather the building envelope of the existing garage into a new backyard cottage but they were unwilling to guarantee it. They recommended that we go through formal land use approval early in the process. Regardless of their final call we did know that we would have to stick within the building envelope of the garage for all portions of the backyard cottage that did not conform to the new ordinance. The potential advantage of using the existing garage is that it would allow us to use up less of the yard space for our new structure.

SCHEMATIC DESIGN OPTION 2


The major element in this design is the creation of a covered outdoor workspace to the south of the cottage.

OPTION-2-PLAN

The covered patio to the south provides a sheltered outdoor workspace. The loft space is pulled back from the east wall allowing two stories of light to fill the first floor studio.

SCHEMATIC DESIGN OPTION 3


This scheme ended up being the winner with Kate and Ric. They felt it was the best fit for their needs in terms of layout and size. It features a simple open plan on the first floor and a second floor that is more private than the lofts in the first two options.

OPTION-3-PLAN

Pass through doors and a simple plan define this scheme.
