Bedrooms I would not kick out of bed for eating crackers

The sleeping space is set off with curtains instead of a door to foster an open feel on the ground floor. Bedding from West Elm and a quilt made by Magill’s mother sit atop a platform bed, also from West Elm. The red chairs, originally from Ikea, were another inexpensive secondhand acquisition. The deck chairs feature reversible canvas slings by the fashion designer Julie Brown.

Ever the energetic grandmother, Ferguson insisted the house be flexible. In the three guest bedrooms,twin beds are mounted atop a railing system. Pushed together, they form a double bed. When Ferguson wants to accommodate a raft of children, she pushes the twin beds apart, thanks to the rails, with the flick of a finger.

Large windows and sliding doors with maximal operability are placed throughout, including the master bedroom, where expansive lift-and-slide mechanisms line three exterior walls. The room is furnished by a custom mahogany headboard and bed frame by Larry Hepler and a glass Murano lamp by Massimiliano Schiavon.

All of the furniture was meticulously handmade by Klebba and Reis to serve the family’s needs.

In this sustainable home in Silicon Valley, the primary suite opens to a deck and fern garden with large, sliding glass doors.

The 4,000-square-foot home previously contained a single bedroom, a egregious waste of space. Subdivided into three bedrooms, the house is shared by the Bloemkers and their four children.
