An Ingenious In-law Suite on an Unforgiving Sitecomments (0) February 15th, 2013 in Blogs
(This case history from Renovation 4th Edition reflects today's need to maximize space and functionality, conserve resources, and create homes that can accommodate life's changes.)
At first glance, the space beneath the garage was a daunting place to add an in-law suite. It was dark, steeply pitched and--perched on one of San Francisco's foggier hillsides--damp most of the year. Structurally, the rehab was sure to be complex as well. So by the time the owners, Narayan and Melanie, met with Stephen Shoup of buildingLab, they had spent a lot of time pondering a renovation, and had as many questions as answers.
Initially, the suite would house an au pair but some day one of their parents would probably move in. So it needed to be a self-contained living space. Aesthetically, the suite should match the main house. For budgetary reasons, it must be built entirely within the footprint of the garage, 490 sq. ft. And because both clients were very busy, they wanted to simplify decision-making and lines of responsibility. They wanted just one entity, buildingLab, to handle all aspects of the job--whether wrangling with the city, refining the design, or explaining the technical implications of a choice.
Clients' requirements: "Create an in-law suite from the raw space under the garage. Tie the new unit to the main house by incorporating similar materials, proportions and aesthetics. Though the unit should be autonomous, it need not be slavishly so, because whoever lives in the suite will be an active part of our lives."
Design Solutions: The size of the space and the disposition of the site largely decided the layout. To create a complete dwelling in so little space, clearly some areas would have to do double duty--be multi-functional, that is.
Two walls had no opportunities for windows: the south wall was cut into the hillside, whereas the east wall bordered the stairs. Thus the large walk-in closet, which needed no natural light, was placed in the SE corner; the kitchenette (which was too small for entertaining) was placed next to the closet, along the south wall. Clearly, the living room area needed light, so it was situated along the north wall, near the door. The main trade-off was between the bath and bed. Because it would be calming to lie in bed and look out into the forest, the owners decided to situate the Murphy bed in the SW corner, so the bath was consigned to the remaining (NE) corner, with white laminated glass to assure its privacy.
Heavy Lifting: To create a clear open space for the suite, it was necessary to replace an existing wood girder with a 600-lb steel I-beam that spanned 22 ft. This operation will chronicled in Feb 22's CozyDigz blog, "Replacing a Wooden Girder with a Steel I-Beam."
Green touches: FSC-certified lumber. Locally sourced materials whenever possible. Low-flow bath fixtures. Using a recirculation loop to pull hot water to the suite, saving water. Recycled cotton insulation. Created new dwelling on existing lot, within existing structure. Multi-functional, space-conserving layout and furniture.
Clients' parting thoughts: "We chose a design-build firm…based on our fundamental belief that if you are detail oriented, like us, then you need someone who understands the build implications of the design and conversely the design choices that will best fit your taste if build constraints emerge…A design-build approach seems the most customer-centric one to us because they are involved with you all through the project."
