Suzanne and Brooks Kelley at the back of their 1,100-square-foot guest cottage.

The owners toured this home, which surrounds a mature tipu tipu tree, while visiting relatives for the day. The brick is original to the 1947 construction.

The Conservatorium is outfitted with furniture by Cassina, Kartell, and Living Divani.

The atrium features a wealth of materials: the brick of the original structure, a glass roof, and steel beams supporting the new structure.

Sliding doors by Quantum were made to look like the original panes that couldn't be saved, and they lead to a fire pit outside.

Just like the exterior, the interior rooms feature a mix of design influences: traditional blue plates hold court with minimalist furnishings.

The rooms feature 100-percent Egyptian cotton bedding, flat-screen TVs, a deep soaking tub and separate shower, safety deposit box, complimentary WiFi, and a prime view of the cityscape.

Here's a shot of the lounge.

This shot of the stairwell shows the myriad materials used: metal, marble, and brick.

The hotel was originally the Rijkspostspaarbank building. In 1978 the bank moved and the building became a music conservatorium five years later. In 2008 the Conservatorium of Amsterdam moved locations and Set Hotels purchased the building.

The serene spa features a full menu of services including facials, manicures, and massages.

“A building can have far greater impact than the space it stands in.”—William Carpenter, architect and resident

New zoning allowed for a zero-lot-line structure, but required a public storefront, which Carpenter uses as an art gallery.

See Arch restored the exterior fireplace wall and painted it a deep blue hue to match the repainted blue timber cladding.

The Airstream Haus’s interior is minimalist, but comfortable, boasting a fully functional kitchen and queen-size bed that doubles as a couch.

The Kelleys furnished the cottage with help from Suzanne’s daughter Betsy Burbank of Betsy Burbank Interiors. Classic modernist icons, such as a Saarinen Womb chair for Knoll, a Herman Miller Eames lounge chair, and an Eileen Grey E1027 side table look at home alongside present-day pieces such as an Encore sofa (which handily folds down into a sleeping surface) from Room & Board and a Doka rug designed and produced by Stephanie Odegard. The Wohlert pendant lights from Louis Poulsen were designed by Vilhelm Wohlert in 1959, but grouped as such, they appear distinctly contemporary.

This open-concept Amsterdam loft features soaring 15-foot ceilings, an Eames lounge chair and ottoman, and a Jielde light. Throughout the home, Standard Studio architects Wouter Slot and Jurjen van Hulzen favored raw materials, including concrete, oiled oak, and hot-rolled steel, all of which complemented the original space's industrial feel. Tucked smartly underneath the loft, a compact home office features functional built-in shelving and an Eames DSR chair.

“I really believe buildings are part of a city as an organism.”—William Carpenter, architect and resident

Black and white kitchen tiles add visual interest to this stunning modern kitchen by IKEA.

Neutra's Kaufmann home was initially designed for living just two months out of the year. Yet after the original owner passed, future tenants attempted to retrofit the space for year-long use. An air conditioning unit was placed atop the roof, and square footage was added, enclosing this courtyard. To return it to its original state, the current owner underwent a five-year restoration and reopened this courtyard to honor the original design. Photo: Tim Street-Porter

The first step was to tear out the existing wall-to-wall carpeting and replace it with cabin-grade, oak flooring to give the house a classic feel and to help anchor the more modern walls and trim. They ordered the flooring from a large company and despite it being the cheapest option offered, the total expense came to $2,300 for materials, making the wood floors—according to Anderson—their biggest splurge.

The apartment is accessed via an old freight elevator. The cabinetry around the elevator entrance—including a massive bookshelf and storage space—is black, contrasting with the white brick walls and the white oak joinery.

Pleased with the pop-up they designed last summer, Frame approached i29 again this fall to construct a more long-term installation: a shop meant to evoke a 3-D walk through of an issue of their magazine.

Fashion-tech designer Anouk Wipprecht’s white Spider Dress 2.0 was developed with Philip Wilck along the lines of a previous dress she made inspired by arachnids. The 3D-printed robotic garment with eight jointed arms (activated by sensors and Intel Edison chips with artificial bio-signal intelligence) protects the wearer. Depending on the wearer's mood—agitated or pleased—the arms of the dress spring upward to ward off intrusions.

Part of the PIXEL series, the Ripple 2.0 Coffee Table, shown in walnut with powder coated steel pulls, takes the same inspiration of the movement created by a ripple of water and brings it to a different, slightly darker, place by using a different kind of wood and pixelating the motif further.

The smooth, raven-hued island in this kitchen is made of oak with a thin stone countertop. A Foscarini Gregg Pendant hangs overhead.

The newly built house, just feet from the water’s edge, occupies the space where a decaying farmhouse once stood.

The floor tile is from Virginia Tile, while the wall tile is from Daltile.
